The Amphenol 86503-414HLF is a 14-position, dual-row unshrouded header from the BERGSTIK® II series, designed for board-to-board interconnect applications. It uses a 0.100" (2.54 mm) square-pin grid on both pitch and row spacing, with all positions loaded. The through-hole solder termination and tin-plated phosphor bronze contacts make it a straightforward, cost-effective choice for parallel PCB stacking or wire-to-board via a mating receptacle.
Key specs and what they mean for the build
The 0.100" pitch is the standard legacy grid — it matches the vast installed base of BergStik-compatible receptacles and perf-board layouts. The 14 circuits in two rows give you a 2x7 footprint; the unshrouded design means no keying or polarization, so the mating receptacle must be aligned by eye during assembly. Rated 5 A per contact at 110 V, with tin-on-tin contact finish — adequate for signal and moderate power duty, but the tin plating limits the connector to about 50 mating cycles before fretting becomes a concern. The UL94 V-0 black housing is standard for equipment inside an enclosure requiring flame rating.
