Only 3 of the 5 positions are loaded with pins, so the BOM line for the mating half should account for the actual circuit count, not the housing size. The shrouded-1 wall and friction lock give this header a positive retention against vibration — a step up from unshrouded breakaway headers — without needing a secondary latch. It mates with standard MTA-156 crimp-socket housings (like the 640550 series) using the same 0.156\" pitch. ## Current rating and temperature ceiling The tin-plated mating surface and post handle the current the attached wire can carry, up to the 600VAC voltage rating.","metaTitle":"643495-2 TE Connectivity MTA-156 Header, 5 Pos, 3.96mm","metaDescription":"643495-2 TE Connectivity AMP Connectors MTA-156 header, 5 positions, 0.156\" (3.96mm) pitch, shrouded-1 wall, friction lock, tin-plated, active production.","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":"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":"3","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0700","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.07000","currency":"USD"},{"qty":10,"price":"$1.00400","currency":"USD"},{"qty":100,"price":"$0.86410","currency":"USD"},{"qty":500,"price":"$0.76138","currency":"USD"},{"qty":1000,"price":"$0.68197","currency":"USD"},{"qty":5000,"price":"$0.61658","currency":"USD"},{"qty":10000,"price":"$0.57810","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/7d0cb0738f602e0586ad67ec19a7733c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the pitch of 643495-2?","answer":"The pitch is 0.156\" (3.96mm), which is the standard MTA-156 spacing."},{"question":"What is the mating connector for 643495-2?","answer":"It mates with MTA-156 crimp-socket receptacles (e.g., TE 640550 series) using the same 0.156\" pitch and friction-lock interface."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/643495-2","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/643495-2 when reusing this data.
