Voltage rating is 250 VAC, consistent with general-purpose signal and low-power distribution applications. Available in bulk packaging. ## Comparison with Peer Headers Compared to the 1-292164-1 (CT series, 11 positions, 0.079\" pitch, shrouded, right-angle), the 3-644456-6 offers a wider 0.100\" pitch and unshrouded vertical orientation — a simpler footprint for manual wiring but less protection against mis-mating. The CT header uses a detent lock for retention; the MTA-100 relies on the receptacle's latch.","metaTitle":"3-644456-6 TE Connectivity MTA-100 Header, 6 Pos, 2.54 mm","metaDescription":"3-644456-6 TE Connectivity AMP Connectors MTA-100 unshrouded header, 6 positions, 0.100\" pitch, tin plating, through-hole, UL94 V-0.","metaKeywords":null},"attributes":{"series":"MTA-100","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Style":"Board to Cable/Wire","Series":"MTA-100","Package":"Bulk","Features":"-","Shrouding":"Unshrouded","Termination":"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":"644456","Insulation Material":"Thermoplastic","Number of Positions":"6","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":"$0.5500","priceTiers":[{"qty":1,"price":"$0.55000","currency":"USD"},{"qty":10,"price":"$0.47600","currency":"USD"},{"qty":100,"price":"$0.39280","currency":"USD"},{"qty":500,"price":"$0.34156","currency":"USD"},{"qty":1000,"price":"$0.28179","currency":"USD"},{"qty":5000,"price":"$0.24763","currency":"USD"},{"qty":10000,"price":"$0.23055","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/305c50b34b3f718eb64ff1129ed620d7.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/3-644456-6/alternatives.json"},"ai":{"faq":[{"question":"Is 3-644456-6 RoHS compliant?","answer":"Yes, it is RoHS compliant per the manufacturer's listing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/3-644456-6","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/3-644456-6 when reusing this data.
