The Amphenol BERGSTIK 55101-G1103LF is a 3-position, single-row unshrouded pin header on the standard 0.100" (2.54 mm) pitch. It is a board-to-board interconnect, right-angle through-hole mounted, with a push-pull fastening style. The mating contacts are finished with 30.0 µin (0.76 µm) gold over GXT™, while the solder tails get a thicker 100.0 µin (2.54 µm) tin finish. Rated at 5 A per circuit and 110 V, with a UL94 V-0 black housing.
Lifecycle and Sourcing
This part is officially Obsolete per the manufacturer. There is no listed direct successor or cross-reference. For existing BOM lines, sourcing runs through the surplus and broker channel — quoted to order against an RFQ. Current availability and pricing are confirmed at quote time; no stock-holding claim is made here.
What the Key Ratings Mean for Fit
The 0.100" (2.54 mm) pitch is the industry-standard footprint for legacy through-hole layouts — it matches the vast majority of 0.1" grid protoboard and older PCB designs. The 5 A per-circuit rating is typical for a signal-level header; the limiting factor is the pin density and the temperature rise in the unshrouded housing, not the phosphor bronze contact itself. The gold GXT™ plating on the mating side (30 µin) gives good corrosion resistance and cycle life for field-serviceable connections, while the tin-plated tails are standard for solder assembly.
