31-position 0.30mm-pitch FPC — what fits and where
The 3-2328724-1: This is a 31-position, 0.30mm-pitch FPC connector from TE Connectivity's FPC series, with bottom contacts and a flip-lock actuator. The 31-position count is uncommon; confirm the FPC tail has exactly 31 pads before committing the BOM line. The flip-lock actuator provides zero-insertion-force mating and positive retention — no secondary latch needed, but the actuator must be fully closed to hold the FPC under vibration.
Current and voltage ceiling — 0.5A per contact at 30V
Rated 0.5A per contact at 30V. The 0.30mm pitch limits current per circuit more than the contact itself — derate if more than 50% of positions carry current simultaneously.
Mating and termination — bottom contact, 0.20mm FPC thickness
Accepts 0.20mm-thick FPC with tapered cable end. Bottom contact configuration means the FPC pads face down toward the PCB. The flip-lock actuator secures the FPC without a secondary latch — confirm the FPC tail length matches the connector's insertion depth from the product drawing.
