Rated 3 A per contact with tin-lead mating and post plating, 100.0µin (2.54µm) thick, and housed in a UL94 V-0 thermoplastic insulator rated -65°C to 105°C. ## Board fit and routing density The 0.100\" (2.54mm) pitch and 0.100\" row spacing define the board footprint — the 42 positions occupy a 2.100\" row length. The 0.230\" (5.84mm) mating contact length and 0.090\" (2.29mm) post length set the through-hole depth. Unshrouded design allows the header to be snapped to length for non-standard circuit counts; the breakaway construction separates at scored grooves between positions.","metaTitle":"TE 4-103777-0-21 AMPMODU Mod II Header, 42 Pos, 2.54mm","metaDescription":"TE Connectivity AMPMODU Mod II header 4-103777-0-21: 42 positions, dual row, 0.100\" pitch, 3 A, tin-lead plating, through-hole, unshrouded breakaway.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Style":"Board to Board or Cable","Series":"AMPMODU Mod II","Package":"Bulk","Features":"-","Shrouding":"Unshrouded","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header, Breakaway","Fastening Type":"Push-Pull","Number of Rows":"2","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.090\\\" (2.29mm)","Ingress Protection":"-","Base Product Number":"103777","Insulation Material":"Thermoplastic","Number of Positions":"42","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin-Lead","Contact Length - Post":"0.090\\\" (2.29mm)","Current Rating (Amps)":"3A","Operating Temperature":"-65°C~105°C","Mated Stacking Heights":"-","Overall Contact Length":"0.410\\\" (10.41mm)","Contact Finish - Mating":"Tin-Lead","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":"100.0µin (2.54µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2600","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/4-103777-0-21/alternatives.json"},"ai":{"faq":[{"question":"How can I request pricing and availability for 4-103777-0-21?","answer":"Submit an RFQ against the BOM quantity.
