I am trying to find a SSOP 24 to DIP adapter with .635mm pitch (.025") Everything I have found so far is .65mm pitch. The chip I want to use is the Si4844 AM/FM/SW receiver. This chip doesn't quite line up on the .65mm adapters. People have said they were able to use a .65mm adapter for this ic but this is going to be my first SMT job. I would prefer to use an adapter that lines up perfectly to increase the odds of success.

Does anyone have a source for that?

 

Digikey, Mouser, maybe Radio Shack. Have you thought about rolling your own? The datasheet for the Si4844 (https://www.silabs.com/Support Documents/TechnicalDocs/Si4844-B20.pdf) shows a nice drawing of the pad layout that could be scaled to actual size and used as a pcb etching mask.

 

Doubtful if you are going to find a socket if that is what you are looking for. You could solder your own.

Check the body size against this one: http://www.proto-advantage.com/store/product_info.php?products_id=3100159 It's 32 pin, but so what. Right pitch.
Use the drawings.

 

You could do just FM pretty easily

You might want to contact sparkfun. Maybe they have something in the works???

 

I second spinnaker's suggestion. That's what I use, and where I get them too.

I keep a box of all different sizes on hand in advance of need. Same with proto boards, the "sea of holes" on 0.1" centers, plated thru on real FR4 material; I keep various sizes on hand.

They take 2-3 weeks typically to make it to my door with the free shipping.

 

I think the OP is worried about soldering that chip. I have done stuff just a little bigger but my hands are shaky and I got the job done. You should be able to do OK. Just read up on surface mount soldering.

 

If proto-advantage has the part, you can get the stencil. Then it's cake.

That one is too wide. The space between the pads is wider than the entire width of the Si4844, including pins.

This one is the correct pitch and width, but is 48 pins:

KeepItSImpleStupid you hit the nail on the head with this:

It's got a few extra pins, but so what.

Thank you.
