Discontinued Molex & ALPS Card Connector Cross-Reference → KINGCONN Replacements

Holding a Molex or ALPS card-socket part number that distributors now list as obsolete? This table maps those part numbers to KINGCONN sockets still in production for the same card interface. Matching basis: identical card interface standard and eject mechanism, with the published mated height of both parts side by side. The matches have been reviewed by KINGCONN R&D. Ask KINGCONN before you order — send the original part number or your drawing through the form; the Taoyuan R&D team confirms pin-out and footprint, then you order against that reply.

How to read this table

The status column is read from the lifecycle field of Digi-Key / Mouser product listings, with the source link and check date; parts not marked end-of-life at a distributor are not listed.
A KINGCONN match is a catalog part with the same card interface and eject mechanism; the published mated height is shown where available so you can judge the difference yourself.
A cross-reference is a starting point, not a drop-in guarantee: pin assignment, hold-down positions and detect-switch polarity can differ — compare drawings before ordering.
