What are these called?

Postby dominicbeesley » Mon Nov 27, 2017 11:37 am

The riser/header/dil plug/board to board connector things?

I'd like some for my experiments, but also to replace the broken ones on my WE 1770 boards (all have at least one missing pin!)

I've just spent an hour on RS and Farnell but don't seem to be able to find anything.

They're sort of unobtanium - the standard method is to use some turned pin headers, then stack up turned pin sockets underneath to the right height.

Samtec make them and call them APA adapter plugs.

Toby Electronics sell them but you have to contact them to get the right size:

The 40-pin 0.6" version was called APA-640-T-N when I ordered some a good while back.

This outfit is quoting for them @ £5.59 each (+ £12 shipping - or free shipping if your order is > ~£33). I'm guessing VAT will be on top:

I'm afraid you'll have to call/email them. They were £2.99 each when I bought them but that was back in 2008!

The ones I was thinking about are these:

Probably no good with a width of 0.3"!

But, courtesy, of Simon Inns, I have a few of these. They would need extra height e.g. other turned pin sockets (there're only 16mm high - top to bottom of pins!), however, that would be good to save damage to the delicate pins.

Yes please Dave, they look like they would work. I'll PM you.

I'll probably solder an socket upside down on the duaghter board anyway as I've had nothing but bother with these things.

Thanks RobC for that part-number that's led to a few more avenues...

Digikey have them listed at £5.59 each and reckon a lead time of 18/12/17

Personally, I'm looking for that kind of thing but as low profile as possible, not as high. Does anybody know of something cheaper and/or more available than the Precidip ones which cost about 5p/pin?
