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.","metaTitle":"Amphenol BERGSTIK 55101-G1103LF, 3-pos Header, 2.54mm, 5A","metaDescription":"Amphenol BERGSTIK 55101-G1103LF 3-position unshrouded pin header, 0.100\" pitch, right-angle through-hole, 5A, gold GXT mating contacts.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Style":"Board to Board","Series":"BERGSTIK®","Package":"Bag","Features":"-","Shrouding":"Unshrouded","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole, Right Angle","Connector Type":"Header","Fastening Type":"Push-Pull","Number of Rows":"1","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Obsolete","Voltage Rating":"110V","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.140\\\" (3.56mm)","Ingress Protection":"-","Base Product Number":"55101","Insulation Material":"-","Number of Positions":"3","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.090\\\" (2.29mm)","Current Rating (Amps)":"5A","Operating Temperature":"-","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Gold, GXT™","Contact Length - Mating":"0.230\\\" (5.84mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"100.0µin (2.54µm)","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/5df463f350e91e65e23bd6425bccdf67.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/55101-G1103LF/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 55101-G1103LF?","answer":"As an obsolete part, 55101-G1103LF is sourced through independent distribution and quoted to order against an RFQ.
