Getting Electronic Parts

There are several suppliers of electronic parts that advertise in Model Railroader and other model train magazines.  Circuitron has a good selection of parts applicable to the model railroader.  Check out your local train store.

This section is intended to introduce you to suppliers of electronic parts that do not advertise in model train hobby magazines.  These are companies that I've had good experiences with that you may want to try.  They don't bite and may offer lower prices.  Their main business is electronic parts.  Virtually all take charge cards.  Some have a minimum; usually about $25.

Most have quite substantial catalogs with more choices than you may have ever seen before.  Call and get a catalog before you need something.  Then use my suggestions below to zero in on exactly what you want.

You can ask questions about the product.  The people who you place your order with will not usually be able to answer them.  Tell them you need to ask someone a technical question about a part you want to buy.  They may ask if you want to talk to an applications technician or engineer.  Say yes.  When you are connected with that person, ask away!

SUGGESTION #7-1: Radio Shack     http://www.RadioShack.com

Radio Shack is a great place to get the components you need to make a track wiring buzzer or when you need just a few things in a pinch.

Getting #18AWG solid wire in the color that you want at Radio Shack has a curious problem.  Catalog item #278-1217 is available in both red and black.  Since both colors are stocked under the same number, a store cannot order the color you want if they don't have it.  You cannot call a store and have them just look on their computer to see what they have in stock.  You need to make sure they go look at what they have hanging on the wall.  Fortunately, a store employee knew of this problem and he called around and found the black I was looking for.  You might want to buy a roll or two extra when you see it as there is no telling when you will be able to buy the color you want when you need it.

SUGGESTION #7-2: Digikey

1-800-DIGI-KEY  (344-4539)     http://www.digikey.com

Good prices, items in stock, and popular with hobbyists.

SUGGESTION #7-3: Allied Electronics

1-800-433-5700

If you think DigiKey's catalog is impressive, this one is even bigger. There is almost nothing this company doesn't sell. They cost a little more, so they are not usually my first choice.  Allied is also quite good.

SUGGESTION #7-6: Mouser Electronics

1-800-346-6873      http://www.mouser.com

This company carries similar products to Digikey.  Their catalog is on-line, or you can get a free copy of the catalog in print, on a CD-ROM, or both!  Very popular with hobbyists.  This company carries the Insulation Displacement Connectors (IDCs) mentioned in Tony Koester's August 1998 article in Model Railroader.  For IDC part numbers, see below.  Mouser's prices are even better than Digi-Key's.

SUGGESTION #7-12: Hosfelt Electronics:  Hobbyist Supplier and Transformers.

Hosfelt isn't quite as big as any of the above, but they are a supplier friendly to hobbyists and they are one of the few that carry transformers appropriate for DCC use.  They do not have an online catalog.  So go to their web page now and order a catalog so you will know what they have when you need it.  Hosfelt Electronics  http://www.hosfelt.com

SUGGESTION: Electronic Tools for the Professional.

These companies are the Micro-Mark of electronic tools — Ideal brand wire strippers, electric wire strippers that don't put much pulling force on small wires, magnifying lights, and much, much more. Some of the tools are exotic tools for the professional that does electronic work day-in and day-out so they may be out of your reach. But if there is an electronic tool you have seen and want, these companies seems to have it.

HMC Electronics:  http://www.hmcelectronics.com

Techni-Tool: http://www.techni-tool.com

SUGGESTION #7-7: THIS is an Electronics Store!  Fry's Electronics    http://www.frys.com

This is the store an electronics hobbyist always wished Radio Shack would become.   It's interesting they now occupy dead Incredible Universe stores in the Dallas, TX area.  They have what seems like everything.  Parts, computers, test equipment like oscilloscopes.  In the silicon valley area, one store is reported to look like a giant IC.  Another, a pyramid.  They even sell snacks for those all-night work sessions and non electronic magazines to make sure you stay a well rounded individual.

International Electronics Suppliers: Farnell and Element 14

For those not in the United States, here are two international suppliers of electronic parts. Farnell seems to be in every country except the United States. Element 14 has a social media portal for electronic design engineers and contains datasheets and advice on parts.

http://www.farnell.com

http://www.element14.com

SUGGESTION #7-4: For Layout Wire, Tie Wraps, and Heat Shrink Tubing:

Your local home improvement store!  See the track wiring section for the types of wire they carry.  They also have a great selection of heat shrink tubing and tie wraps.

SUGGESTION #7-5:  Decoder Harness Plugs:

Samtec manufacturers the plugs.  Their web page includes listings of their dealers.  I have not dealt with Samtec.  They are a manufacturer and as such may not want to do retail sales.  Be sure to contact one of their dealers, especially if you need small quantities.
Male plug P/N:  SDL-104-TT-19      Female plug P/N:  BDL-104-T-F

Note:  This information came from Larry Puckett's column in Model Railroading.  He frequently covers DCC topics.  I found I liked the rest of the magazine, too!

The following carry decoder plugs.  No doubt, there are many others.

Tried & True Trains

RECOMMENDATION #7-11:  Use #6 Screw Terminal Strips.

Terminal strips come in several sizes.  Below I list locking spade lugs.  When you compare the availability of terminal strips and locking spading lugs, you find the #6 screw terminal strip and locking spade lugs are a good all-around size for model railroaders.  I recommend you standardize model railroad on this size.  All parts below having to do with terminal strips I have based on this standard.

Useful Parts

Looking through a train catalog is sometimes fun, but electronic catalogs rarely are. So here are common items that are frequently needed by model railroaders.

I'm sorry it isn't practical to provide pages numbers. As soon as a given company comes out with a new catalog, any page numbers I would list are all doomed to be wrong. Murphy makes sure of it!

Please note!  The prices provided are only provided to give you an idea of what the items cost.  I do not intend to try too hard to keep these current.  These are the prices at the time I purchased them and entered them into this page.  If you buy a larger or smaller quantity, your price will vary accordingly.  If you are inclined to send me the current price you pay, I will be glad to update the list.

RIBBON CABLES

(For Zimo Decoders)

C3AAT-1618M-ND
($3.69)

16 pin, tin plated contacts, multicolored, 18" ribbon cable with connectors on both ends. Cut this cable in half and you will be able to do two Zimo decoders.  Since you will mate this connector one time and leave it alone inside the locomotive, you don't need higher grade connector

Note:  Ribbon cables will fail if it flexed a lot, handled often, or if strain is placed on the cable.  Strain is particularly important to a cable that is inside a locomotive.  Be sure there is no strain on the cable.  It will fail eventually - and probably a lot sooner than either of us wants!

C3AAG-1618M-ND
($4.24)

16 pin, gold plated contacts, multicolored, 18" ribbon cable with connectors on both ends. For those who would prefer a gold plated connector for their Zimo decoder.

SUGGESTION 7-8:  Circuit Board Throw Bars and Phosphor Bronze:

Making circuit board throw bars isn't fun.  In fact, it can be very dangerous! 

Fast Tracks Hobbyworks, Inc. sells PC board ties already cut to size and gapped. Order on line at: http://www.handlaidtrack.com/Fast-Tracks-PC-Board-Ties-s/38.htm While you are at it, you may want to pick up a Frog Juicer for your turnout. U.S. modelers will note that Fast Tracks is a Canadian company. I have dealt with several Canadian companies, including Fast Tracks. Shipping cost and normal ground delivery has never been a problem for me.

Cloverhouse has a catalog of strips of PC boards you can use for ties, as well as, all sorts of craftsman supplies and tools.  He has sheets and wires of phosphor bronze as well as sheets of brass and nickel silver. Clover House, POB 62, Sebasstopol, CA  95473-0062. www.cloverhouse.com Clover House does not accept phone orders, but you can fax orders to him. Also, you cannot order from the website.

Note:  Phosphor bronze is a great material.  It's springy, conducts electricity well, and doesn't corrode badly.  I recommend it over anything you might use strips of brass or copper for.

RECOMMENDATION #7-9: Liquid Flux:

H&N Electronics  http://www.ccis.com/home/hn  Their Supersafe flux is great!  Amateur and advanced solderers will wonder how you ever soldered without it.  For more information, see the section on Soldering.

SUGGESTION #7-12: Sockets for the 1156 Tail Light Bulb - Reasonably Priced!

The price was $1.73 each abd come leads about 6" long.

Globe Specialty Company

Go to page 64 or search for part number 322X-56

One may send check or M.O. or they will ship UPS COD.

Here is another source that is even cheaper and seems to be an ideal choice. They are $0.99 each and come from a company called SuperBrightLEDs.com   http://www.superbrightleds.com

The socket you want is the one on the right with the white wire and single contact in the socket. As you can see, the socket is metal and has two mounting tabs with holes. You can screw down the socket to a terminal strip or your benchwork.

You can tell by the name, this website primarily sells LED products. So finding the 1156 socket is a little difficult. Follow this link and it will take you right to it:

http://www.superbrightleds.com/cgi-bin/store/index.cgi?action=DispPage&Page2Disp=%2Fhobby.htm%23socks

Then click on "See Prices and Buy." Then click on 1156. You want the BA15S-SW socket. If you are like me, you are a little skeptical of a socket for a hot light bulb coming from a company that sells cool running LED products. I obtained one of their sockets and it is the real deal made of metal.

Note on Using LEDs. You might be thinking, "Why don't I use LED tail light bulbs?" They run cooler, use less energy, and generally is the green thing to do. It won't work as a short protector. Don't try it. Don't even think it. The reason is that a light bulb has a property that makes it work. That is, it has a very low resistance when cold. There is minimal voltage drop across a light bulb when cold. This allows trains to run. When it heats up, it has a high resistance and limits the amount of current to a short. An LED tail light has a significant voltage drop, even when off, and allows only a minimal current to flow. Your trains won't run.

SUGGESTION #7-15: Flat Cable (Telco) Supplier in Germany. waving deutschland flag

Thanks to Sebastian Daeunert for supplying information on where someone in Germany can find the flat cable used on Digitrax and some other of the US made DCC systems. This cable is frequently referred to "Telco" cable as it is used on US phones. Telco is simply short for telecommunications.

Note: If you are using Digitrax, they do not require that you use this cable. It is simply convenient to do so.

Sebastian found the cable at Conrad Electronic (www.conrad.de). He was able to get the right plugs and found the price reasonable — 4.70 Euro for a 3 Meter cable.

921442-41 for 3 Meter Cable

921442-42 for 6 Meter Cable

921442-43 for 10 Meter Cable
