The tin-plated mating surface is rated for the typical wire-to-board mating cycle count in a fixed installation; gold is not needed here because the connector is seldom unmated after commissioning. ## Pitch, Positions, and Locking — Fit Check 17 positions, all loaded, in a single row. The friction lock engages with a ramp on the receptacle shroud — you will feel it click when fully seated. The 0.156\" (3.96 mm) pitch is the same across the MTA-156 family, so the board footprint is consistent whether you use a 2-position or 24-position header. Rated 600 VAC — sufficient for 120/240/480 VAC industrial circuits.","metaTitle":"1-640445-7 TE Connectivity MTA-156 Header, 17 Pos","metaDescription":"1-640445-7 TE Connectivity AMP Connectors MTA-156 series header, 17 positions, 0.156\" (3.96 mm) pitch, single-row, shrouded with friction lock, through-hole","metaKeywords":null},"attributes":{"series":"MTA-156","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-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","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":"0.425\\\" (10.80mm)","Ingress Protection":"-","Base Product Number":"640445","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"17","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.125\\\" (3.18mm)","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-55°C~105°C","Mated Stacking Heights":"-","Overall Contact Length":"0.650\\\" (16.51mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.400\\\" (10.16mm)","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":"$1.9800","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.98000","currency":"USD"},{"qty":10,"price":"$1.72300","currency":"USD"},{"qty":100,"price":"$1.53930","currency":"USD"},{"qty":500,"price":"$1.28272","currency":"USD"},{"qty":1000,"price":"$1.09948","currency":"USD"},{"qty":5000,"price":"$0.97487","currency":"USD"},{"qty":10000,"price":"$0.95288","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/6a6ae74c758a809f2940ce5a6656561e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is 1-640445-7 a shrouded header?","answer":"Yes, it is a shrouded header with a single wall (1-wall shroud) that guides the mating receptacle and protects the male pins during insertion."},{"question":"What is the locking mechanism on 1-640445-7?","answer":"The header uses a friction lock built into the shroud."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/1-640445-7","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/1-640445-7 when reusing this data.
