Board-to-board breakaway, 14 positions, 0.100" pitch
The 77315-418-14LF: Tin-plated mating contacts carry 3 A per contact; the through-hole right-angle orientation suits edge-mount or parallel-PCB layouts where the mated board sits perpendicular to the main board.
Position count in the unshrouded single-row line
The 14-position 77315-418-14LF is one member of the BERGSTIK unshrouded single-row header family; the pitch (0.100"), contact finish (tin), and right-angle orientation are shared across the series, so the position count alone determines the board footprint length.
