What the 93690-102-20LF Is
The AMPHENOL BERGSTIK 93690-102-20LF is a dual-row 2.54 mm pitch male header in the BERGSTIK series, configured as a board-to-board or cable breakaway header with 20 positions loaded. Square male pins accept IDC receptacles, card-edge connectors, or matching cable headers — the breakaway design lets you snap the strip to the exact position count your board needs. It mounts through-hole and supports both press-fit and solder termination, so it lands on a PCB by either method depending on your assembly process. Contact finish splits across the connector: gold GXT plating at 30.0 µin (0.76 µm) on the mating interface drives durability and low contact resistance at the plug face, while the post side carries tin at 39.4 µin (1.00 µm) — tin solders readily and the thicker deposit holds up to press-fit insertion into plated-through holes without wicking issues. Rated 5 A per circuit at the connector interface and 110 V between adjacent contacts, with an insulation height of 0.100 inch (2.54 mm) that sits flush with the board surface without protrusion.
Where It Goes
Board-to-board stacking, card-edge acceptance, and cable harness midpoints all fall within the BERGSTIK sweet spot. The push-pull fastening holds the mating half under vibration — the thermoplastic housing carries a UL94 V-0 flammability rating, so it is acceptable in enclosed equipment where flame retarding is required. Without a shroud the header exposes the pin row along the unmate side, so it is not a sealed connector: no IP rating applies and it belongs in an enclosure or behind a panel in any application where contamination is a concern.
