It carries 20 male square pins loaded across two rows, with a row-to-row spacing of 0.100\" (2.54mm) — a layout that matches the footprint of a matching BergStik II receptacle or IDC socket. The 5 A per-contact current rating is typical for this pitch class, and the 100.0 µ\" (2.54 µm) tin plating on the mating surface provides a robust, cost-effective contact finish for moderate-cycle applications. As an unshrouded header, the 86503-420HLF relies on the mating receptacle for alignment — there is no shroud to guide the plug, so the board layout must provide mechanical registration if the assembly sees repeated mating or vibration. The 0.250\" (6.35mm) mating pin length provides sufficient wipe for reliable contact. Termination is through-hole solder; the 0.120\" (3.05mm) post length fits typical 0.062\" (1.6mm) PCBs with room for the solder fillet.","metaTitle":"Amphenol 86503-420HLF BergStik II Header, 20 Pos","metaDescription":"Amphenol 86503-420HLF BergStik II unshrouded header, 20 positions, 0.100\" pitch, 5 A, tin plating.
