The FCI 86832-402HLF is a 2-position, dual-row BERGSTIK® II unshrouded header designed for board-to-board interconnects. With a 0.100" (2.54mm) pitch and 0.100" (2.54mm) row spacing, it mates with standard 0.100" pitch receptacles. The 2-position count is the key fit parameter — confirm your BOM calls for exactly two circuits before specifying, as the dual-row layout occupies the same footprint as a 4-position single-row header. The overall contact length of 0.525" (13.34mm) with a 0.325" (8.26mm) mating length and 0.100" (2.54mm) post length defines the board-to-board stack height budget — the mating half must accommodate this pin length.
Within the BERGSTIK® II series, the 86832-402HLF is the 2-position dual-row variant. The closest sibling is the 86832-404HLF at 4 positions — same pitch, same 5 A rating, same tin plating. The decision between them is purely the circuit count: 2 positions for a two-wire interconnect versus 4 for a four-wire. No other functional difference exists between these two members.
