Through-hole breakaway, 32 positions at 0.100" pitch
The 77313-427-32LF is the 32-position, dual-row member of Amphenol ICC's BERGSTIK breakaway header line. It is unshrouded with push-pull fastening and through-hole solder termination. Mating and row spacing are both 0.100" (2.54mm). Each contact is rated 3A with tin-plated mating and post surfaces, and the housing carries a UL94 V-0 flammability rating.
Board footprint and routing density
The 0.100" (2.54mm) pitch and row spacing set the board footprint — a standard 0.100" grid. The unshrouded design leaves the mating pins exposed, which keeps the board-edge profile low and allows the header to be snapped to length for non-standard position counts.
