What this 0.50 mm pitch ZIF connector is for
The 5051102691 is a 26-position, 0.50 mm pitch FFC/FPC connector from the Molex Easy-On FD19 series. The 25 mating cycle rating confirms it is not intended for frequent reconnection.
Fit check: cable thickness, pitch, and contact position
The 0.50 mm pitch must match the cable's conductor spacing exactly—any mismatch will prevent insertion or cause intermittent contact. Contacts are on the bottom side of the connector, meaning the cable's conductive pads must face downward when inserted. The flip-lock actuator secures the cable without requiring insertion force on the contacts. Gold plating on the contacts (1.97 µin) and phosphor bronze base metal provide corrosion resistance for the rated 25 cycles, but the thin gold layer is not designed for high-wear environments.
Sourcing and compliance for production planning
RoHS non-compliant—this is a critical flag for any BOM requiring RoHS exemption-free compliance. Verify your product's exemption status before committing. The housing material is LCP glass-filled (UL94 V-0), and the actuator is nylon glass-filled. No stock-holding claim; sourcing confirmed per RFQ.
