This is a single-wall shrouded header, meaning the plastic wall protects the pins on one side only. In a board-to-cable application, orient the header so the open side faces away from the cable entry to minimise the chance of a short if the wire is pushed sideways. ## How this header compares to a 2.00mm-pitch alternative The 640388-2 carries a higher voltage rating (600VAC) and wider pitch (3.96mm), which gives it a higher per-contact current ceiling and easier board routing, but at the cost of a larger footprint.","metaTitle":"640388-2 TE Connectivity MTA-156 Header 2 Pos 3.96mm","metaDescription":"640388-2 TE Connectivity AMP Connectors MTA-156 series header, 2 positions, 3.96mm pitch, tin plating, friction lock, active production.","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":"Circular","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":"640388","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"2","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":"$0.2100","priceTiers":[{"qty":1,"price":"$0.21000","currency":"USD"},{"qty":10,"price":"$0.17900","currency":"USD"},{"qty":100,"price":"$0.16300","currency":"USD"},{"qty":500,"price":"$0.12654","currency":"USD"},{"qty":1000,"price":"$0.11761","currency":"USD"},{"qty":5000,"price":"$0.10421","currency":"USD"},{"qty":10000,"price":"$0.09230","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/42cab01b09a94914227d0d8e2650ce77.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/640388-2/alternatives.json"},"ai":{"faq":[{"question":"Is 640388-2 RoHS compliant?","answer":"Yes, it is RoHS compliant per the manufacturer listing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/640388-2","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/640388-2 when reusing this data.
