What this connector is
The Amphenol FCI 86832-124HLF is a dual-row 0.100-inch pitch board-to-board male header in the BERGSTIK II series — 24 circuits loaded, all positions populated. It terminates via through-hole solder and uses a push-pull fastening type without shrouding. Contacts are square-pin phosphor bronze with gold or Gold GXT plating at 30 µin (0.76 µm) on the mating surface.
Ratings that drive the fit decision
Pitch is 0.100 inches (2.54 mm) on a dual-row grid, so the board footprint is a standard 0.100-inch lattice — routing density and keep-out are what you would expect for this pitch class. Current rating is 5 A per contact at the stated voltage of 110 V; the phosphor bronze base with 30 µin gold or GXT plating handles that duty without the temperature-rise concerns that plague thin tin plating at equivalent current. The insulation height of 0.100 inches (2.54 mm) and overall contact length of 0.525 inches (13.34 mm) give you the mated stack dimension for z-height budget planning. Because it is unshrouded, the mating half must carry its own polarizing key or the board layout must enforce orientation — mis-mate risk sits on the receptacle side, not the header. Material is rated UL94 V-0 — the insulation housing passes the most demanding residential and industrial panel flammability tier, which matters if the board assembly is going into a UL-certified end product.
Where it is used
BERGSTIK II headers are a long-run commercial product line used in industrial control, instrumentation, and board-stacking applications where a standard 0.100-inch pitch dual-row footprint gives the design flexibility to mate with a wide range of matching receptacles or IDC-style headers. The push-pull fastening type suits applications where the board is either drop-shipped as a mated pair or handled in a fixture that does not rely on a screw-lock to maintain engagement. The 24-position count sits in the middle of the BERGSTIK II range — large enough to carry a bus or multi-signal cluster, compact enough to stay within a single board region without consuming the full board width.
Lifecycle and sourcing posture
86832-124HLF carries an Active product status per available records. Sourced to order against BOM quantity via RFQ; the base product number 86832 belongs to a BERGSTIK II family with fixed 0.100-inch pitch and row spacing — variants in the series share the same footprint.
