The orange closed-end housing blocks the last cavity, preventing a stray terminal from being inserted and leaving a live contact exposed at the end of the harness. It accepts 18 AWG wire, either discrete or ribbon cable. The tooling required is the standard MTA-100/MTA-156 hand tool or a bench press with the appropriate IDC head; the same tool family covers the whole MTA series, so if you already build MTA harnesses, the setup is identical.","metaTitle":"TE Connectivity 3-640431-3 MTA-156 Receptacle, 3 Pos, IDC","metaDescription":"TE Connectivity MTA-156 3-640431-3 receptacle, 3 positions, 0.156\" pitch, IDC termination for 18 AWG, tin plating, orange housing.","metaKeywords":null},"attributes":{"series":"MTA-156","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Circular Connectors","Panel-Mount & In-Line Circular"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Orange","Pitch":"0.156\\\" (3.96mm)","Series":"MTA-156","Package":"Bulk","Features":"Closed End","Wire Type":"Discrete or Ribbon Cable","Wire Gauge":"18 AWG","Row Spacing":"-","Contact Type":"Female Socket","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Receptacle","Contact Finish":"Tin","Fastening Type":"-","Number of Rows":"1","Product Status":"Active","lifecycle_stage":"unknown","Cable Termination":"IDC","Base Product Number":"640431","Number of Positions":"3","Contact Finish Thickness":"80.0µin (2.03µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4400","priceTiers":[{"qty":1,"price":"$0.44000","currency":"USD"},{"qty":10,"price":"$0.41300","currency":"USD"},{"qty":25,"price":"$0.41160","currency":"USD"},{"qty":50,"price":"$0.40140","currency":"USD"},{"qty":100,"price":"$0.34420","currency":"USD"},{"qty":250,"price":"$0.31136","currency":"USD"},{"qty":500,"price":"$0.29408","currency":"USD"},{"qty":1000,"price":"$0.25774","currency":"USD"},{"qty":2500,"price":"$0.25428","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/666aa6088d5b5c3aed984c32a7d9ec9a.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/3-640431-3/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 3-640431-3?","answer":"The 3-640431-3 is an active TE Connectivity part, sourced to order through independent distribution."},{"question":"What tools are recommended for installing 3-640431-3?","answer":"Standard MTA-series IDC hand tools or a bench press with the appropriate IDC head are used.
