Dual-row breakaway header at 0.100" pitch
The 77313-427-18LF is the 18-position member of Amphenol's BERGSTIK breakaway header family, configured as a dual-row unshrouded through-hole header with push-pull fastening. Rated 3 A per contact with tin-plated mating and post surfaces, the header operates from -65°C to 130°C and carries a UL94 V-0 thermoplastic housing.
Position count and shared footprint
The 18-position 77313-427-18LF uses the same 0.100" (2.54 mm) pitch and 0.100" row spacing as other BERGSTIK breakaway headers — the board footprint and routing density are consistent across the series; the position count is the selection variable.
