Product details

What this 17-position FFC connector does on your board

The 5052781733 is a 17-position, 0.50mm pitch FFC/FPC connector from Molex's Easy-On FS19 series. It accepts a 0.30mm-thick FFC with tabbed, tapered ends and terminates via solder to the PCB in a right-angle orientation.

Flip lock and solder retention keep the cable seated

The flip lock actuator (black polyamide, glass-filled) clamps the FFC against the bottom contacts. It locks positively without a secondary latch — vibration won't work it loose.

Frequently asked questions

Does 5052781733 have a flip lock mechanism?

Yes, it uses a flip lock actuator. The black polyamide lever flips down to clamp the FFC against the bottom contacts, providing positive retention without a secondary latch.

What is the equivalent of 5052781733?

The closest functional equivalent is the 505278-1733, which shares the same pitch, position count, height, and flip lock. The difference is the housing color — beige vs black — and the packaging options. Both are active.
