What this connector is and where it fits
The Amphenol FCI BERGSTIK 93690-102-18LF is an 18-position, dual-row male pin header at 0.100" (2.54 mm) pitch, rated 5 A per circuit at 110 V. The style is listed as Board to Board or Cable, meaning it serves as the board-side termination for a range of wire-to-board and board-to-board harness topologies. The header is unshrouded and breakaway-style — the individual pin strips snap apart cleanly, so you can pop off a sub-set of positions without cutting — and it mounts through-hole with press-fit or solder termination. Square male pins mate into the matching IDC or insulation-displacement receptacle; the push-pull fastening relies on pin-to-socket interference rather than a locking latch, so confirm your receptacle housing has adequate retention for the application vibration profile. The dual-row spacing is 0.100", matching standard 0.100" pitch daughtercards and carrier boards — the pitch and row spacing together define the footprint class this header lives in. What separates this from a plain tin header is the split plating: gold GXT™ at the mating interface (30.0 µin / 0.76 µm,) over a copper alloy contact, with tin on the post side at 39.4 µin (1.00 µm,). The gold GXT grade gives lower contact resistance at first mate and better fretting resistance across reconnection cycles compared to an all-tin finish — a meaningful difference if the assembly sees field service or repeated mating. The tin post plating is sized for solderability and long-term board-level reliability, not for the mating interface itself. All 18 positions are loaded, so there are no empty stubs in the footprint to account for.
Ratings that drive the fit decision
Current rating is 5 A per circuit — the per-contact ceiling at the stated conditions. The voltage rating of 110 V is typical for signal-level and low-voltage power interconnect.
