I need one of these:
It's a low-profile smd type DDR3 SODIMM socket for laptop use with those little metal spring-release tabs.
I need one with 4 mm total height. All the ones I can find are 5-plus mm. I've seen 4 mm parts in manufacturer datasheets but can't find any US distributors.
And it needs to be standard orientation flavor (key right-of-center, relative to user's view when inserting the SODIMM).
That last point is glossed-over pretty easily by even product drawings: as far as I can determine these come in both orientations: the two types are identical except that the polarity key is right- or left-of center. I think the "standard" model is right-of-center key.
Mouser has only vertical orientation sockets (a la desktop motherboard). Digi-Key has the correct type but wrong key location (reverse style).
