The Amphenol FCI 86837-404HLF is a 4-position, dual-row unshrouded header from the BERGSTIK® II series, on the standard 0.100" (2.54mm) pitch. It is a through-hole, board-to-board interconnect with tin-plated phosphor bronze male pins rated 5A per circuit at 110V.
Fit and Board Layout
The 0.100" (2.54mm) pitch and 0.100" row spacing place this on the industry-standard grid, so the footprint is a straight match for any 0.100" dual-row receptacle. The 0.120" (3.05mm) solder post length is sized for standard 1.6mm PCBs; the 0.380" (9.65mm) mating pin length gives good wipe before the contact bottoms out. The 4-position count is the minimum for a dual-row header — two pins per row — which keeps the board footprint compact.
