The closed end blocks the last cavity, so you cannot over-insert or mis-seat the cable; it also polarises the mate against an open-ended header. The yellow housing stands out in a bundle — useful when you have several MTA-156 harnesses running to the same board. ## IDC Termination and Wire Gauge No crimp tool, no solder; just a press. The wire gauge is fixed at 20 AWG, and the connector accepts either discrete wires or ribbon cable. The tin-plated contacts (80.0µin / 2.03µm thickness) are rated for the current the 20 AWG wire can carry in a low-cycle-count application; tin is not a high-mating-cycle finish, but for a one-time IDC install it is the standard choice. ## Obsolete — Sourcing Reality If your BOM calls for this exact 17-position closed-end IDC receptacle, we can still locate it; just submit an RFQ with your quantity.","metaTitle":"TE MTA-156 4-640432-7, 17 Pos IDC Receptacle, Obsolete","metaDescription":"TE Connectivity MTA-156 4-640432-7 is a 17-position, 0.156\" (3.96mm) pitch IDC receptacle, yellow, closed end, for 20 AWG discrete or ribbon cable.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circular Connectors"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Yellow","Pitch":"0.156\\\" (3.96mm)","Series":"MTA-156","Package":"Box","Features":"Closed End","Wire Type":"Discrete or Ribbon Cable","Wire Gauge":"20 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":"Obsolete","lifecycle_stage":"unknown","Cable Termination":"IDC","Base Product Number":"640432","Number of Positions":"17","Contact Finish Thickness":"80.0µin (2.03µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/4378ca7f8cb8904c61ed97f2af193bd4.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/4-640432-7/alternatives.json"},"ai":{"faq":[{"question":"Is 4-640432-7 obsolete?","answer":"Yes, TE Connectivity lists the 4-640432-7 as Obsolete."},{"question":"What is the pitch of the MTA-156 connector?","answer":"The pitch is 0.156\" (3.96mm), which is the standard for the MTA-156 series.
