Board-to-board breakaway header, 31 positions
The 77315-401-31LF is the 31-position member of Amphenol ICC (FCI)'s BERGSTIK unshrouded breakaway header line, configured as a single-row board-to-board interconnect. Tin-plated phosphor bronze contacts carry 3 A per contact across a -65°C to 125°C operating range; the UL94 V-0 thermoplastic housing suits equipment inside an enclosure requiring flame rating.
Single-row pitch and footprint
The 0.100" (2.54 mm) pitch and single-row layout define the board footprint — the 31 positions occupy a 3.00" (76.2 mm) row length. The right-angle through-hole termination places the mating interface parallel to the PCB edge.
