Board-to-Board Header for General-Purpose Interconnects
The FCI BERGSTIK® II 86840-422HLF is a 22-position, dual-row, unshrouded male pin header on a 0.100" (2.54 mm) pitch. It is a through-hole, right-angle component designed for board-to-board stacking or wire-to-board applications when mated with a compatible receptacle. The tin-plated mating finish and phosphor bronze contacts are rated for 5 A per circuit, making it suitable for general-purpose signal and moderate power distribution inside enclosed equipment.
Key Specs and What They Mean for Fit
The 0.100" pitch and 0.100" row spacing define a standard 0.1-inch grid footprint — the same layout used by legacy BergStik and many other 2.54 mm headers, so board layout is straightforward. The 22 positions are fully loaded across two rows, giving 11 pins per row. The right-angle orientation places the pin axis parallel to the board, which suits edge-mount applications where the mating connector approaches from the side rather than vertically. The 5 A per-circuit rating is typical for a 0.100" pitch header with tin contacts. Tin plating is adequate for moderate mating cycles (typically 25–50 cycles) in clean, indoor environments. For higher cycle counts or corrosive atmospheres, a gold-plated variant would be preferred. The UL94 V-0 housing meets the flame rating required for equipment inside an enclosure. The unshrouded design means the pins are exposed — no plastic shroud protects them from bending during handling or mating. This is common for low-cost board-to-board headers where the mating receptacle provides the alignment. The push-pull fastening type means no locking latch; retention relies on the friction of the pin-receptacle interface.
