The 4-wall shroud protects the pins during handling and guides the receptacle into alignment. A friction lock on the shroud holds the mated pair without a separate latch or hardware, providing vibration resistance for the wire-to-board joint in general-purpose equipment. ## Contact plating and current handling for moderate-duty cycles Both the mating contact finish and the solder post are tin-plated. Tin-on-tin interfaces are cost-effective for applications with limited mating cycles — typical for a header that mates once during assembly and stays connected. The current rating varies by wire gauge, so the limiting factor is the attached wire, not the header pin itself.","metaTitle":"2-644488-3 TE Connectivity MTA-100 Header 3 Pos 2.54 mm","metaDescription":"2-644488-3 TE Connectivity AMP Connectors MTA-100 header, 3 positions, 0.100\" (2.54 mm) pitch, right-angle through-hole, tin contacts, friction lock.","metaKeywords":null},"attributes":{"series":"MTA-100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 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":"Shrouded - 4 Wall","Termination":"Solder","Applications":"General Purpose","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole, Right Angle","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":"0.343\\\" (8.71mm)","Ingress Protection":"-","Base Product Number":"644488","Insulation Material":"Polyester","Number of Positions":"3","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.130\\\" (3.30mm)","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-55°C ~ 105°C","Mated Stacking Heights":"-","Overall Contact Length":"-","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":"$0.6200","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.62000","currency":"USD"},{"qty":10,"price":"$0.60100","currency":"USD"},{"qty":100,"price":"$0.48490","currency":"USD"},{"qty":500,"price":"$0.42936","currency":"USD"},{"qty":1000,"price":"$0.37632","currency":"USD"},{"qty":5000,"price":"$0.32833","currency":"USD"},{"qty":10000,"price":"$0.31258","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/81d605b30dd155ee70162f41dd9bb683.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the mating connector for 2-644488-3?","answer":"The friction lock on the header engages the corresponding ramp on the receptacle housing."},{"question":"Is 2-644488-3 RoHS compliant?","answer":"Yes, the 2-644488-3 is ROHS3 compliant, meeting the current RoHS directive requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/2-644488-3","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/2-644488-3 when reusing this data.
