The post tails are tin-plated at 100 µinch for good solderability to the PCB. This is a surface-mount header with solder termination — the SMT pads sit on the board surface, so the footprint must match the 1.27 mm pitch and the dual-row layout. In a vibration environment, consider a secondary retention method or a locking header variant.","metaTitle":"73547-105LF Amphenol ICC (FCI) Rib-Cage™ III Header","metaDescription":"Amphenol ICC (FCI) Rib-Cage™ III board-to-board header, 10 circuits, 1.27mm pitch, 30µin gold mating finish, 1 A rating, UL94 V-0.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Style":"Board to Board","Series":"Rib-Cage™ III","Package":"Tube","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Surface Mount","Connector Type":"Header","Fastening Type":"Push-Pull","Number of Rows":"2","Pitch - Mating":"0.050\\\" (1.27mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"-","Insulation Color":"Natural","Insulation Height":"0.364\\\" (9.25mm)","Ingress Protection":"-","Base Product Number":"73547","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"10","Row Spacing - Mating":"0.050\\\" (1.27mm)","Contact Finish - Post":"Tin","Contact Length - Post":"-","Current Rating (Amps)":"1A (DC)","Operating Temperature":"-55°C~130°C","Mated Stacking Heights":"9.93mm","Overall Contact Length":"-","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.130\\\" (3.30mm)","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":"$0.9932","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/731b3cee66723ea6cf4ca02249714427.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the pinout of 73547-105LF?","answer":"The header has 10 positions, all loaded, arranged in two rows with 1.27 mm pitch between rows and between positions.
