Breakaway design and board fit
The 77315-101-07LF: The breakaway construction lets the header be snapped to the desired position count from a longer strip — the 7-position version is the factory-loaded length, with all positions populated. Through-hole right-angle mounting places the 0.225" (5.72mm) mating pin perpendicular to the board; the 0.101" (2.57mm) solder post fits standard 0.100" pitch footprints.
