The Amphenol 87900-414HLF is a 14-position, dual-row unshrouded header from the BERGSTIK® II series, built on the standard 0.100" (2.54mm) pitch that matches breadboard and legacy footprint layouts. It carries male square pins with a full tin finish — 100.0µin (2.54µm) on the mating surface — rated for 5 A per contact at the stated conditions.
The 0.100" (2.54mm) pitch on both rows and the 0.100" (2.54mm) row spacing means this header drops onto a standard 0.100" x 0.100" grid — no unusual pad geometry. The 0.120" (3.05mm) post length is short enough for single-board through-hole but long enough for a typical 1.6mm PCB with a solder fillet. The overall contact length of 0.940" (23.88mm) gives a generous 0.720" (18.29mm) mating pin for stacking receptacles at a distance.
The 14 positions are all loaded, so there are no unpopulated pin locations to track. Termination is solder only; the phosphor bronze contacts are tin-finished end to end (mating side and post side), which keeps the bill of materials simple but limits mating cycle life compared to gold. For a one-time assembly or low-cycle board interconnect, the tin-on-tin interface is adequate.
The 110V voltage rating and 5 A per contact current rating are typical for signal-level board interconnects in this pitch class.
