China and Japan are not the same country exactly. If I recall correctly they are not even great friends.

The 'german' kind of this connector is actually available in the US:

Would be interesting to see how fast the number in stock would go down

I am new and sorry for anything I should have noticed already. I am looking for break out boards as pictured at the top of this post for the 121 pin molex ecu connector. I see that someone has designed one from this site, but im not sure how to use the file source or where I can send it to have the board made? thanks for any help pointing me in the right direction

I have a few of these, just listed them at https://www.tindie.com/stores/russian/ - https://www.tindie.com/products/russian ... -bare-pcb/

If you are not in the USA shipping price would be a disaster :(

Anyway, back to your question how to make your own batch: one of the links above would get you to https://svn.code.sf.net/p/rusefi/code/t ... gerber.zip file.

"Gerbers" are these magic files you provide to a PCB shop to make boards. You can take that gerber ZIP file to https://oshpark.com/ or https://www.seeedstudio.com/ or any other PCB shop.

The board would be a 2 layer, would go as "under 5cm x 15cm", your call on color and thickness.

The source files are done in KICAD. If you are looking to make changes to the board, you can do the changes in KICAD. Or you can grab the gerber files and send them to a PCB house to have them fabricated.

Thanks all, I am going to send it off to seeestudio.

Hopefully 1 OZ copper should be enough even for the power side? I made it exactly 5cmx15cm. Also, I am trying to source an ECU enclosure here in the US to use with the 121 pin connector, if I cant find one, I guess I will grab an Altima ECU to use as a mock up before ordering 10+ from China later on.

I'm not sure if it was noticed / mentioned, I was looking into these connectors and found some info at some point.

Korean variant is much cheaper (at least at mouser). 1/3rd the price. eg 81p plug is $6 or something vs $20.

German variant has at least two subtypes. On motronic ME7.x for VW cars they use this to key things (eg. whether the car has wideband O2 or not, was one use. Maybe there are more).

here you can see the key

I'll look the ECUs I have and post the tyco part numbers for the two variants sometime.

What about PCB thickness? For example this specific connector board. Is the popular default 1.6mm the best thickness, or should it be maybe only 1.0mm? 0.8mm?

I don't think thickness matters that much. The connectors are reasonably strong with any PCB installed.

I will order 0.8mm just to save the planet, also 1.6mm looks so last century.

Just a random fact: Audi is placing ECUs inside a cage so that you cannot just unplug a connector. Same break away bolts like they use on steering column locks.

side latches are fine

I did similar to my projects. EDC 15+ ECU is very cheap in my country. Is possible to share 3D model of connector for PCB renderings?

First post in this thread has links to TE site - TE site has 3D PDF and other 3D files, we used those.

Thank you.
I didn't know about Eagle's library for this connector and everything measured and draw footprint myself :x :x :x :x :x

We use KICAD and do not use Eagle.

I know, but when learn Eagle few years ago is hard to switch my brain to KiKad. KiKAD is a very good, and free for charge stuff.
