Board-to-Board Header for Standard 0.100" Footprints
The Amphenol 86503-432HLF is a 32-position, dual-row male header from the BERGSTIK II series, built on the industry-standard 0.100" (2.54mm) pitch. All 32 positions are loaded, giving a 2x16 pin layout that matches common parallel-interface and signal-routing BOMs. The 0.100" pitch provides enough creepage for the 110 V rating while keeping the board footprint compatible with legacy DIP and IDC layouts. The housing is molded from UL94 V-0 rated black thermoplastic, and the contacts are phosphor bronze with a 100.0 µin (2.54 µm) tin finish on the mating surface and tin on the solder tails.
Mating Half and Build-to-Print Checklist
For a complete build-to-print assembly, the matching half is typically a 32-position IDC socket or a female header with the same pitch and row spacing. The 0.100" (2.54mm) insulation height and 0.250" (6.35mm) mating pin length provide clearance for standard ribbon-cable connectors. The through-hole termination with a 0.120" (3.05mm) post length suits standard 0.062" to 0.093" PCBs.
