Rated 5 A per circuit at 110 V, the tin-plated phosphor bronze contacts (100.0 µin / 2.54 µm on the mating surface) handle signal-level current and moderate power distribution in low-cycle applications — think a single-mate production assembly, not a field-service disconnect that sees dozens of cycles. The UL94 V-0 black housing gives it the flame rating required inside equipment enclosures where a fire stop is mandatory.
Right-angle board footprint and routing
The 0.100" pitch and 0.190" (4.83 mm) insulation height define the keep-out zone on the board. With 46 positions in two rows, the header spans about 2.30 inches along the edge — that is a wide footprint, so confirm the board edge has room for the full row length plus the solder tail clearance. The 0.230" (5.84 mm) post length gives a solid through-hole solder joint on a standard 0.062" board; thicker boards may need a longer post variant.
As an unshrouded header, the 86840-446HLF relies on the mating receptacle housing for polarization and strain relief — the pins themselves have no plastic wall to prevent a mis-mate.
