The 1735265-8 is an 8-position FPC connector on a 0.039" (1.00mm) pitch, terminated by solder to the board and mated with a 0.30mm-thick flat flex cable. The ZIF (Zero Insertion Force) slide lock means you slide the FPC in without forcing contacts, then lock the actuator to wipe the pads and hold them.
At 0.039" (1.00mm) pitch and 8 positions, this connector fits a narrow FPC footprint common in handheld and portable gear. The bottom-contact arrangement means the FPC traces face the PCB, which can simplify routing if the cable bends away from the board. The slide lock adds retention that a simple ZIF flip may not provide under vibration.
ROHS3 compliant, with no known pin-compatible direct replacement within the same base product number family. If you need a different position count or pitch, the 1735265 base series offers other options.
