Parts needed

 

Hello All,

I have an hp1611A Logic State Analyzer that has two broken 15-pin, 2-row card-edge connector sockets, part number 1251-1886.

Would anyone have some of these sockets so I could fix this motherboard?

Thanks in advance.

Christopher
 

Hi,

Might, or not, be the original parts but you certainly want to look at EDAC connectors:
https://edac.net/

This is a 30p PCB mounted connector, I suggest to measure yours with a caliper and compare. They have several different sizes.

There is a store near me that might have these: Midwest Surplus Electronics . They have all kinds of?old school parts . Provide dimensions and I can? check next time I am there.?

The closest match I have found is an EDAC 307-015-521-102, given the spacing and pitch. However, it is only one set of contacts. I checked their catalogue and they do not make one with a set of two contacts.
 

The Cinch number you provided does match those on the motherboard. The ones on eBay do look like the originals. What would be the difference between the '301' of these and the '341' of the originals?
 

@Maciej Kawalkowski

Thank you for this information. I see these are available in the Mouser catalogue.
 

I was at the electronics store but they did not have any 30 position ones. A lot of other ones were available.
 

I think you want these

305-030-520-202

 

In the interim while you look around for the correct connector socket, you might try putting epoxy in the broken ends and put a zip tie around the connector. I used this method for a couple of years until I found my correct connector.

Thanks for the advice. I will give this a try. Problem is that this is to be a replacement board for another 1611A that has a strange fault where the transformer heats to (internal) meltdown after two minutes.

I'll take a look at this.
 

This one is indeed more correct, given it corresponds to the '341' series tag. Never thought I would gather so much knowledge on edge connectors. I love this hp gear!
