NOTE: Is this a JST connector?

This is the common wire connector LIONEL uses on some of its passenger cars:

I need to buy a bunch of these in male/female pairs for LED lighting upgrades for passenger cars. (Note: the LIONEL part sells for $2.50 ea.)

I'd like to know what product this is; and, what lug LIONEL uses, as well as the AWG of the wire.

Thanks for the help.

During LIONEL's 1/2 price off sale I bought one. I went to measure it but my digital caliper's battery was DOA. Getting replacement LR44 tomorrow and will post specs.

Perhaps with specs the mfr. can be id'd.

Will also call/email LIONEL service to see if they know and will tell.

GRJ, what would be a close JST alternative in size and wire AGW?

I don't need to mate to the LIONEL connector, just male/female pairs of that size for LED wiring in passenger cars.

You'll need to pay him $25 for that information.

kidding.

To answer your other question, I use these.

For whatever reason, I couldn't find them last time I looked, don't know what the issue is.

One problem is they're discontinued by Molex and so existing stock is all that's left.

Mouser.com has all the types, I just ordered all the types between 2-pins and 5-pins and the matching pins.

Given Molex has discontinued these, I'll go with the JST you identified.

Thanks, John.

Carl you can use the JST connector but they are more difficult to separate if you intend to use them wire to wire. They were designed for wire to board.
The molex connector linked above are designed for wire to wire connections. Thats why Lionel is now using them in their passenger cars.

Pete, i appreciate your incites. Since the JST products are available pre-wired and will relieve me from having to crimp connections, I'll go with the JST's.

Confession: I tried to find the Molex connectors GRJ referenced on Mouser.com, but gave up after 30 minutes of searching--moderately embarrassing to say the least.

GRJ, if you are still there, how about a link to the Molex product on Mouser.com???

Someone else posted a link from Amazon, so there is that one, too.

Both Tom C and I posted links to pre wired connectors. Pretty cheap too. Given a choice I would go with pre wired too even though I already have the pins and housings.

It is the Molex connector part number 51006-200: Pitch is 2.0 mm, 2 Amp rating. While Molex has discontinued this connector, another company, Daier, seems to be supplying the equivalent. I've seen this connector with 26 awg and 22 awg pigtails. I'm not sure of the current required in the Lionel application.

On Amazon, eBay, etc. they've acquired the JST-DS Losi nomenclature. The "Losi" comes from a major RC manufacturer, Losi, that popularized its use. I don't know why it has acquired the JST-DS nomenclature. Perhaps it's compatible or with the JST PH or PA series (or just looks similar to JST connectors).

Trivia: This is the second instance I've seen Lionel look to the RC market for parts. The other being the Cupola cam.

Pete, if you have actually worked with these Molex connectors, you'll discover they're every bit as hard to separate as the JST connectors! For my test set, where I'm taking the connectors apart all the time, I just hack the little locking nubs to make the connectors easy to separate. :)

I have both and have found the Molex type easier to separate. You can grab the housings vs only the wires with the JSTs. Your mileage obviously varies.
