Contact system and board fit
The 77315-125-07LF is the 7-circuit member of Amphenol's BERGSTIK® breakaway header line, unshrouded, single row, at 0.100" (2.54mm) pitch. Mating contacts are gold or GXT™ finish rated 3A per contact; the post finish is tin. The right-angle through-hole termination suits board-edge or parallel-to-PCB layouts.
Position count across the series
Within the 77315 series the 7-position 77315-125-07LF sits between the 6-position and 8-position siblings — the 0.100" pitch, single-row layout, and gold/GXT™ mating contact finish are shared across the series, so match the position count to the circuit count.
