Board-to-board or cable breakaway header
The 77313-402-58LF is the 58-position member of Amphenol ICC (FCI)'s BERGSTIK® header line, a dual-row unshrouded breakaway header for board-to-board or cable connections. It carries tin-plated mating contacts rated 3A per contact and mounts through-hole with solder termination; the thermoplastic housing is rated UL94 V-0.
Pitch and footprint across the series
The 0.100" (2.54mm) pitch and 0.100" (2.54mm) row spacing are shared across the BERGSTIK® series, so the board footprint is consistent regardless of position count. The 58 positions sit at the high end of the dual-row BERGSTIK® offering — the pitch and footprint are shared, so the selection decision is driven by circuit count.
