It sits on the standard 0.100\" (2.54mm) pitch grid, with the same 0.100\" row spacing, making it a drop-in fit for any BergStik II receptacle or IDC socket on that pitch. Rated 5A per contact with tin plating on both the mating surface and the solder tails, this header is built for cost-sensitive board-to-board or wire-to-board interconnects where the mating cycle count stays low — tin is reliable for a few dozen mates but frets under repeated disconnect. The through-hole right-angle orientation routes the pins parallel to the board, useful for mezzanine stacking or edge-card connections in enclosures with tight z-height budgets. The black UL94 V-0 rated housing and phosphor bronze contacts are standard for this series. ## What the ratings mean for your fit The 0.100\" pitch is the de facto standard for 2.54mm grid prototyping and production boards — any BergStik II or compatible 0.100\" receptacle housing will mate. The 54 positions are fully loaded (all positions populated), so the BOM circuit count must match exactly. The 5A per contact rating is the thermal limit at room temperature; derate for elevated ambient temperatures per the standard BergStik derating curve. The tin-on-tin contact interface is fine for a single install or occasional rework, but if your application calls for frequent mating cycles (50+), a gold-plated sibling in the same series would be the better call. The right-angle through-hole termination gives solid mechanical retention on the PCB, and the 0.230\" post length is standard for most board thicknesses. ## Sourcing and lifecycle The 86840-454HLF is listed as Active on the manufacturer's lifecycle record, meaning it remains in standard production with no announced end-of-life. No official replacement or cross-reference is recorded for this order code — the BergStik II series is broad, and a pin-compatible substitute would need to match the 54-position count, 0.100\" pitch, dual-row, right-angle, unshrouded, tin-plated configuration exactly.","metaTitle":"FCI 86840-454HLF BergStik II Header, 54 Pos, 0.100\" Pitch","metaDescription":"FCI 86840-454HLF BergStik II unshrouded header, 54 positions, 0.100\" pitch, 5A, tin-plated, through-hole right-angle.
