With 17 position cavities but only 13 positions loaded, this header accommodates selective population for harness configurations where not every circuit is needed. The single-row, 3.96mm pitch layout gives you a compact but serviceable footprint — each contact is spaced wide enough for easy routing of 18-24 AWG wire in the mating receptacle. The 600VAC rating is higher than typical for this pitch class, so this header can handle line-voltage distribution within an enclosure as long as the creepage distances are respected. RoHS compliant, housed in a UL94 V-0 rated thermoplastic, and available in bulk packaging.","metaTitle":"TE Connectivity 644959-1 MTA-156 Header, 17 Pos, 3.96mm","metaDescription":"TE Connectivity 644959-1 MTA-156 header, right-angle through-hole, 17 positions (13 loaded), 3.96mm pitch, tin contacts, friction lock.","metaKeywords":null},"attributes":{"series":"MTA-156","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-156","Package":"Bulk","Features":"-","Shrouding":"Shrouded - 1 Wall","Termination":"Solder","Applications":"General Purpose, Industrial","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":"0.156\\\" (3.96mm)","Product Status":"Active","Voltage Rating":"600VAC","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Natural","Insulation Height":"0.300\\\" (7.62mm)","Ingress Protection":"-","Base Product Number":"644959","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"17","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"-","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":"0.400\\\" (10.16mm)","Number of Positions Loaded":"13","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.2900","priceTiers":[{"qty":1,"price":"$6.29000","currency":"USD"},{"qty":10,"price":"$5.51200","currency":"USD"},{"qty":100,"price":"$4.93450","currency":"USD"},{"qty":500,"price":"$4.58824","currency":"USD"},{"qty":1000,"price":"$4.09767","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/44351ab8d9e53213926a8499403b1120.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/644959-1/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy TE Connectivity 644959-1?","answer":"The 644959-1 is available through our distribution channel.
