28-position unshrouded breakaway header
The 77315-424-28LF is the 28-circuit member of Amphenol ICC's BERGSTIK® breakaway header line, a single-row unshrouded board-to-board interconnect on 0.100" (2.54mm) pitch. Tin-plated square pins rated 3 A per contact, through-hole right-angle mounting with solder termination. Operating temperature range -65°C to 125°C; UL94 V-0 thermoplastic housing.
Pitch and footprint fit
The 0.100" (2.54mm) pitch matches standard perf-board and legacy DIP footprints. The unshrouded push-pull fastening allows the header to be broken to a shorter length for non-standard circuit counts — the breakaway construction snaps at the scored grooves between positions. Single-row layout with all 28 positions loaded; the 0.112" (2.84mm) post length suits typical 1.6mm-thick PCBs with through-hole soldering.
