72-position breakaway header, 2.54 mm pitch
The 77313-138-72LF is the 72-circuit member of Amphenol ICC's BERGSTIK breakaway header line, a dual-row unshrouded board-to-board or cable style connector with push-pull fastening. Rated 3A per contact with a gold or GXT mating finish (30.0µin/0.76µm) and tin post finish. The through-hole solder termination and UL94 V-0 thermoplastic insulation suit wave-solder assembly on standard 2.54 mm pitch grids.
Position-count ladder in the BERGSTIK series
The 72-position 77313-138-72LF is the highest-count member of the 77313 series at the 0.100" (2.54mm) pitch. The dual-row layout and 0.100" row spacing are shared across the series — the position count is the sole selection variable for circuit matching. Lower-count siblings (e.g., 36, 50 positions) share the same footprint and plating options.
