It's the receptacle half of a board-to-board mezzanine interconnect, designed to mate with the matching SEARAY header. The 0.050\" pitch packs 100 circuits into a footprint that fits under a mid-size BGA, so the board layout engineer allocates a 10x10 pad array and routes traces between pads at 0.025\" line/space or tighter. The socket sits 0.297\" (7.54mm) above the board, and the mated stack height ranges from 9.5mm to 14.5mm depending on which header height you pair it with — nine options that cover common mezzanine gaps without changing the PCB footprint. The housing includes a board guide to align the socket during reflow, and a pick-and-place pad lets the nozzle handle it without touching the contacts. ## Stack height selection — matching the gap The mated stack heights for the 465577445 are 9.5mm, 10mm, 10.5mm, 11mm, 12mm, 12.5mm, and 14.5mm. That range covers the typical z-height budget between a motherboard and a mezzanine card. The actual stack height depends on which SEARAY header you pair it with — the socket height is fixed at 7.54mm, so the header height determines the total. Pick the stack height that matches your board spacing, then source the corresponding header part number.","metaTitle":"Molex SEARAY 465577445, 100-Position 0.050\" Array Socket","metaDescription":"Molex SEARAY 465577445 high-density array socket, 100 positions, 0.050\" pitch, 30 µ\" gold, SMT.
