Product details

Board-fit note for this 40-position ZIF

The 5052784033: This is a 0.50mm-pitch, 40-position ZIF (zero insertion force) FFC connector from the Molex Easy-On FS19 series. The flip-lock actuator clamps the FFC against bottom-side tin-plated contacts — the FFC inserts with no force, then the lock presses the contacts onto the flex pads. The 20 mating cycles reflect the tin contact finish — adequate for a single assembly cycle or occasional field service, but not for repeated reconnections.

ZIF actuation and cable fit

The flip-lock actuator is black polyamide, glass-filled, and swings open to accept a straight FFC or FPC cable. The contacts are on the bottom side — the cable's conductor pads must face down toward the PCB when inserted.

Frequently asked questions

Is 5052784033 a ZIF connector and what does that mean for assembly?

Yes, it is a ZIF (zero insertion force) connector with a flip-lock actuator. The FFC slides in freely with the actuator open; closing the lock clamps the contacts onto the flex pads without the insertion force required by non-ZIF connectors. This protects the fine-pitch pads from damage during assembly.

What is the closest pin-compatible alternative to 5052784033 in the Easy-On FS19 series?

No official pin-compatible alternative is listed by Molex for this exact 40-position, 0.50mm pitch, bottom-contact ZIF connector. Other FS19 members differ in position count, contact plating, or actuator style — verify the BOM before substituting.
