The Amphenol BERGSTIK II 86503-470HLF is a 70-circuit (2×35) unshrouded male pin header on 0.100-inch (2.54 mm) pitch — the standard breadboard-compatible grid that matches legacy prototype layouts and production PCB tooling. The black UL94 V-0 housing and 0.100-inch insulation height keep the pin field accessible for probing or rework.
As an unshrouded header, the 86503-470HLF mates with any standard 0.100-inch pitch shrouded receptacle housing that accepts 2×35 male pins — typically a BERGSTIK II or compatible IDC socket assembly. The 0.250-inch (6.35 mm) mating contact length provides good wipe for tin-on-tin interfaces. The 0.120-inch (3.05 mm) solder post length suits standard 0.062-inch (1.6 mm) PCBs; for thicker boards, verify the post protrusion through the plated-through hole. No board locks or alignment pegs — the through-hole solder joints carry all mechanical retention.
