ALPS Alpine Card Socket Replacements

Holding a ALPS Alpine card-socket part number that distributors now list as Obsolete or Not for new designs? The table below lists 15 verified-discontinued ALPS Alpine part numbers by card interface, each matched to a KINGCONN socket still in production for the same interface; open a part number for the distributor evidence, the matching basis and the KINGCONN drawing specifications. Matches are reviewed by KINGCONN R&D; ask KINGCONN before you order — pin assignment, hold-down positions and detect-switch polarity can differ from the original.

Frequently asked questions

Does KINGCONN offer replacements for discontinued ALPS Alpine card connectors?

Yes. This page lists 15 ALPS Alpine card-socket part numbers verified as obsolete or not-for-new-design at authorised distributors, each matched to a KINGCONN part with the same card interface and (checked part by part) the same eject mechanism; interfaces covered: microSD sockets, SD card sockets.

What is the matching basis?

Identical card interface standard and eject mechanism (derived separately from the KINGCONN part description and the distributor description — where it cannot be derived, nothing is claimed), with the published mated height of both parts side by side. No drop-in claim: check pin-out, hold-downs and detect-switch polarity against the drawing.

How is the discontinued status verified?

Each status is read from the lifecycle field of the Digi-Key or Mouser product page, with the source link and check date (latest: 2026-09-02); part numbers not marked discontinued at a distributor are not listed.

What should I do before ordering?

Send the ALPS Alpine part number, your drawing or application through the KINGCONN enquiry form; the Taoyuan R&D team checks pin-out and footprint and replies which part fits as-is and which needs a modification.
