DDR3 SODIMM socket?

    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

    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).


  2. Maybe the 4mm guys were 'lying', and re-fashioned their spec sheets.

    Could you not get a set of those as a reference element?

    I have one 4mm socket, removed from a mboard -- wrong "sex" (key located
    wrongly for my needs). Labeled

    "DDR3 1.5V 4.0R" with logo "LCN"

    but I can find no distributors for this.

    This might work:
    That does look good.

    It's now obsoleted by Molex but Digi-Key crossed it to this TE part:

    and it will work for me.

    Thanks for the pointer.

    Have a great weekend.

  5. Probably cheaper to buy a dead version of the entire motherboard, and
    salvage one (or more) from that.
