The body is shrouded on one wall — the open side faces the board edge, which helps guide the mating housing during blind assembly. Only 4 of the 5 positions are loaded with pins; the empty position is common in MTA-156 headers for keying or to reduce contact count in a standard cavity layout. ## Current, plating, and mating cycle reality ## Through-hole mounting and termination The header mounts vertically through-hole with solder termination. The contact length — mating portion is 0.400 inch (10.16mm), post length is 0.125 inch (3.18mm), and overall contact length is 0.650 inch (16.51mm). The housing is natural-colored, glass-filled thermoplastic. Contact material is copper alloy, square pin shape — standard for MTA-156 headers.","metaTitle":"643495-1 TE Connectivity MTA-156 Header, 5 Pos, 3.96mm Pitch","metaDescription":"643495-1 TE Connectivity AMP Connectors MTA-156 header, 5 positions (4 loaded), 3.96mm pitch, shrouded-1 wall, friction lock, through-hole solder, tin","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":"0.425\\\" (10.80mm)","Ingress Protection":"-","Base Product Number":"643495","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"5","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":"4","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7700","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.77000","currency":"USD"},{"qty":10,"price":"$0.74300","currency":"USD"},{"qty":100,"price":"$0.59920","currency":"USD"},{"qty":500,"price":"$0.53050","currency":"USD"},{"qty":1000,"price":"$0.46497","currency":"USD"},{"qty":5000,"price":"$0.40568","currency":"USD"},{"qty":10000,"price":"$0.38621","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/6c579302a048e426fa445d87d5af8123.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the pitch and position count of 643495-1?","answer":"The pitch is 3.96mm (0.156 inches).
