The Amphenol FCI BERGSTIK II 86832-146HLF is a 46-position dual-row unshrouded male header rated 5 A per circuit at 0.100" (2.54 mm) pitch — a standard board-to-board footprint used across industrial controls and instrumentation. Through-hole soldering and push-pull fastening make it a permanent board-mount choice in applications where the daughtercard mates and unmates from a fixed motherboard. Contact finish is gold or Gold GXT at 30.0 µin (0.76 µm) over nickel on the mating interface, with phosphor bronze as the base material.
What the ratings mean for fit
The 46-position dual-row configuration at 0.100" (2.54 mm) pitch clears a standard 2.54 mm routing grid. The 5 A per-contact rating is the limiting figure; the 110 V rating is well above typical signal/logic bus levels, so voltage is not the constraint on this part. The square pin shape and unshrouded body mean keying relies on housing polarization or board-keying features. Insulation height is 0.100" (2.54 mm) and the post extends 0.100" (2.54 mm) beyond the insulator for through-hole engagement. Overall contact length is 0.525" (13.34 mm), giving adequate lead-in for hand or wave-solder board assembly. The mating pin length of 0.325" (8.26 mm) determines the minimum receptacle bore depth.
Typical environments
Board-to-board headers at 0.100" pitch appear in backplane daughtercard interfaces, industrial PLC modules, and test-and-measurement fixtures where the interconnect is made once at final assembly and left mated. UL94 V-0 rating confirms the housing material self-extinguishes, suitable for enclosed equipment where fire-retardance is specified. The product ships in a bag (not tape-and-reel), which reflects its through-hole mounting orientation and use in batch or hand-assembly workflows rather than automated SMT placement.
Sourcing and lifecycle
Listed as Active. Quoted to order against the BOM quantity — confirm position count matches the circuit design before committing. No official cross-reference or successor order code for this 46-position member of the BERGSTIK II series.
