Only 6 positions are loaded — one cavity is empty, likely for keying or polarity alignment, so confirm the mating half's cavity count matches your harness layout. The shrouded-1 wall design and friction lock keep the header aligned and latched to the mating MTA-156 receptacle under vibration — a common need in industrial panel wiring and general-purpose equipment where the cable assembly sees movement. ## Through-hole termination and contact finish The contact length from mating face to board entry is 0.650\" (16.51mm), giving a reasonable z-height for wire-to-board routing. The copper alloy base provides adequate conductivity for the current rating, which varies by wire gauge. ## Lifecycle and sourcing posture No stock-holding claim — quoted per RFQ.","metaTitle":"641991-2 TE Connectivity MTA-156 Header, 7 Pos, 3.96mm Pitch","metaDescription":"641991-2 TE Connectivity AMP Connectors MTA-156 pin header. 7-position, 1-row, 0.156\" pitch, shrouded-1 wall, friction lock, through-hole, tin contacts.","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","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":"0.125\\\" (3.18mm)","Ingress Protection":"-","Base Product Number":"641991","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"7","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":"6","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9200","priceTiers":[{"qty":1,"price":"$0.92000","currency":"USD"},{"qty":10,"price":"$0.88000","currency":"USD"},{"qty":100,"price":"$0.72500","currency":"USD"},{"qty":500,"price":"$0.65912","currency":"USD"},{"qty":1000,"price":"$0.56995","currency":"USD"},{"qty":5000,"price":"$0.48853","currency":"USD"},{"qty":10000,"price":"$0.47985","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/46a02423441b158e74f8e849da034571.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/641991-2/alternatives.json"},"ai":{"faq":[{"question":"Is 641991-2 a shrouded header?","answer":"Yes — it has a shrouded-1 wall design, which provides partial side-wall protection for the pins and guides the mating receptacle into alignment."},{"question":"What is the pitch of 641991-2?","answer":"The pitch is 0.156\" (3.96mm), standard for the MTA-156 series.
