Product details

18-position 0.50mm pitch FFC connector for compact board layouts

The 5052781833: This Molex Easy-On FS19 connector packs 18 circuits into a 0.50mm pitch, fitting a narrow FFC cable for dense PCB routing.

Signal current and mating cycle limits

Rated 0.5A per contact, this connector handles low-current digital or control signals—not power delivery. The tin-plated contacts are rated for 25 mating cycles, enough for production harness assembly and field service but not repeated reconnection.

Flip-lock actuation and FFC thickness compatibility

The flip-lock actuator secures the FFC without a secondary latch; it accepts 0.30mm thick cable with tabbed, tapered ends. The bottom-contact design mates the FFC pads to the connector terminals on the lower side of the cable.

Frequently asked questions

What is the pitch and position count of 5052781833?

0.50mm pitch, 18 positions.

Does 5052781833 have a replacement or equivalent part?

The Easy-On FS19 series includes other position counts, but a pin-compatible alternative would need matching pitch, orientation, and actuator style.

Is 5052781833 compatible with 0.5mm pitch FFC cables?

Yes. The 0.50mm pitch and 0.30mm FFC thickness spec match standard 0.5mm-pitch FFC with tabbed, tapered ends.
