No official pin-compatible successor or cross-reference exists from TE — this is the current production part number for the 9-position unshrouded MTA-100 header.","metaTitle":"3-644695-9 TE Connectivity MTA-100 Header, 9-Pos","metaDescription":"3-644695-9 TE Connectivity AMP Connectors MTA-100 unshrouded header, 9 circuits, 0.100\" pitch, through-hole, tin-plated, UL94 V-0.","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":"Unshrouded","Termination":"Kinked Pin, Solder","Applications":"General Purpose","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"-","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":"Natural","Insulation Height":"0.100\\\" (2.54mm)","Ingress Protection":"-","Base Product Number":"644695","Insulation Material":"Thermoplastic","Number of Positions":"9","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.110\\\" (2.79mm)","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-55°C~105°C","Mated Stacking Heights":"-","Overall Contact Length":"0.505\\\" (12.83mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.295\\\" (7.49mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"150.0µin (3.81µm)","Contact Finish Thickness - Mating":"150.0µin (3.81µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5827","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/fcee9782bc901f9c90edf5bd60763ead.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/3-644695-9/alternatives.json"},"ai":{"faq":[{"question":"How can I order 3-644695-9 and get a price?","answer":"The 3-644695-9 is sourced to order against your BOM quantity."},{"question":"Is 3-644695-9 compatible with standard MTA-100 receptacles?","answer":"Yes. The 0.100\" pitch and unshrouded male pin layout are designed to mate with TE MTA-100 IDC and crimp receptacles.
