DDR2 SODIMM connector

Sun Dec 14, 2014 2:44 pm

I am making a one-off IO board for the Compute Module, only that I am having trouble trying to source the DDR2 SODIMM connector cheaply.
I live in Ireland, so that needs to be factored in.

RS Compoments charges 27 euro for a single connector, so I will only use them as a last resort.

Digi-Key has a better price, charging approx 29 euro for 4 connectors, including shipping.

I am leaning towards Digi-Key, but I would like to know if there is a cheaper place to source it from...
I don't really want to get it out of a scrap laptop Motherboard, since soldering the connector to my IO board will be hard enough without having to de-solder it(And risking damage to it!)...

And just to make sure, I need a DDR2 SDRAM, SODIMM, 200 pin, Right angle surface mount connector? Are there any other things like contact finishes, thickness, etc that I need to know about?


Thanks

Lol, Thanks. I forgot all about Ebay... That one seller does not ship to Ireland unfortunately, but I'll have a look at the other offers.

Thanks Jamesh! :mrgreen:

It would be great if RS & Farnell listed all the components used to build Pi's and development kits!
I realise that would not include BCM2835, DDR ram or PCB but offering the LAN9512 etc. and all the connectors, and passives would be extremely useful.
