Rated 5 A per circuit at 110 V, with 30.0 µ" (0.76 µm) gold plating on the mating surface, it is a general-purpose board-to-board interconnect for through-hole solder attachment.
Within the BergStik® II family, the 87916-109HLF sits as a 9-position single-row member. The 0.830" (21.08 mm) mating pin length provides a long wipe distance for reliable contact, while the 0.128" (3.25 mm) solder tail suits standard 1.6 mm PCB thickness.
This is an unshrouded header — the pins are exposed on all sides, which means there is no physical keying to prevent a reversed or offset mate. In a harness or board-stacking application, the mating receptacle must provide the polarization. The 0.100" pitch is identical to the legacy 2.54 mm grid used on prototyping boards and standard pin headers, so it fits existing footprints without layout changes. The 1.058" (26.87 mm) overall contact length gives a tall profile above the board; verify clearance in your enclosure before specifying.
