The Amphenol FCI 86503-408HLF is the 8-circuit member of the BERGSTIK II dual-row pin header series — a board-to-board board-stack header rated 5 A per contact at 0.100" (2.54mm) pitch with tin-plated phosphor bronze contacts and a push-pull fastening interface.
All contacts are populated and finished in 100 µin (2.54 µm) tin on both the mating interface and the solder post — a single plating grade that handles the full 5 A per-contact rating without a gold-upgrade option in this variant. The insulator is black with a 0.100" (2.54mm) height above the board surface, giving a low-profile stack entry point. The header is unshrouded and uses push-pull engagement — mating half selection must confirm the matching receptacle or housing accepts an unshrouded square-pin dual-row with 0.100" row spacing and the same 8-position count. Material flammability is rated UL94 V-0 — the standard requirement for enclosed equipment in industrial and infrastructure applications where the connector sits inside a sealed housing.
The 86503-408HLF ships in a bag per the standard package type. The BERGSTIK II series shares a common footprint and mating interface across multiple position counts — parametric search on base product 86503 will surface variants at higher circuit counts in the same header family.
Production status is Active. Quoted to order against BOM quantity with no official successor or cross-reference listed. Verify position count and confirm the mating half before committing to the BOM line.
