Product details

Where this 0.30 mm pitch FPC connector fits

The 5047542120 is a 21-position, 0.30 mm pitch FPC connector from Molex's BackFlip / Easy-On LA75 series. The right-angle SMT orientation keeps the mated assembly low — 0.75 mm above the board — which matters when stacking boards in a tight z-height budget. Gold-plated contacts (3.94 µin) on both top and bottom sides of the FPC handle repeated mating cycles — the connector is rated for 10 cycles, typical for a ZIF-style FPC connector used in assembly rather than field-service disconnect. The 0.2 A per-contact current rating and 50 V voltage ceiling confirm this is a signal-only interconnect.

Mating and FPC preparation

This connector accepts a tapered-end FPC, 0.20 mm thick. The flip-lock backlock actuator opens fully, the FPC inserts with the contact pads facing either top or bottom (the connector contacts both sides), then the actuator locks down.

Frequently asked questions

What is the exact pitch of the Molex 5047542120?

The pitch is 0.012" (0.30 mm). This is the tightest pitch in the Easy-On LA75 series, so the FPC must be precisely aligned during insertion.

Does the 5047542120 come in cut tape packaging?

The Cut Tape version is suitable for prototype or low-volume assembly.
