Its single-row contacts are on a 0.100\" (2.54mm) pitch, rated 250VAC, and use tin-plated mating surfaces for cost-effective signal duty. ## Position count and series fit Within the MTA-100 series, the 3-644861-1 carries 11 positions in a single row at 0.100\" (2.54mm) pitch — the friction lock and 4-wall shrouding are shared across the series, so the position count is the selection variable.","metaTitle":"TE MTA-100 3-644861-1 Header, 11 Pos, 0.100\" Pitch","metaDescription":"TE Connectivity AMP Connectors MTA-100 header 3-644861-1: 11 positions, 0.100\" (2.54mm) pitch, shrouded 4-wall, friction lock, through-hole, tin-plated","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 Cable/Wire","Series":"MTA-100","Package":"Bulk","Features":"-","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"General Purpose","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Friction Lock","Number of Rows":"1","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"250VAC","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Black","Insulation Height":"0.410\\\" (10.41mm)","Ingress Protection":"-","Base Product Number":"644861","Insulation Material":"Polyester","Number of Positions":"11","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.140\\\" (3.56mm)","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-55°C~105°C","Mated Stacking Heights":"-","Overall Contact Length":"0.440\\\" (11.18mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.200\\\" (5.08mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2093","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/89a4de5171c97c94b0959718e00c1bc4.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/3-644861-1/alternatives.json"},"ai":{"faq":[{"question":"What is the 3-644861-1's style and series?","answer":"The style is Board to Cable/Wire, and the series is MTA-100."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/3-644861-1","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/te-connectivity-amp-connectors/3-644861-1 when reusing this data.
