C-Board connectors replacement

[mpatou]

Hi

I have a fully working CPS1 C-Board, but it has some poor contacts on two of its connectors that make it impossible to use.

I searched on many websites with no result. Does anyone know what replacement part can I use, or where those connectors could be found?

Many thanks!

Here’s some that should work fine, I think they use standard pitch.
This is for (10) but you can find them individually from many sellers.

^those will work, assuming you get the correct pin count, but they do not populate the socket fully. It is possible to connect them incorrectly, as a result.

Below are correct replacements. None in stock at that link, but possibly can be found elsewhere or looking for a slight part number variation that gets you the same basic part.

While looking for 9140-4500PL, I found this

https://fr.farnell.com/3m/8540-4500pl/embase-ci-40-voies/dp/9138676?ost=9138676

It looks exactly the same, but it's available! I can't find any availability for 9140-4500PL (discontinued?)
