The 0.156\" (3.96mm) pitch matches the standard MTA-156 header footprint, and the closed-end feature blocks the last position to prevent a one-off cable insertion error. ## IDC Termination and Wire Handling This connector terminates via insulation displacement — no crimp tool, no loose terminals. The 24 AWG wire gauge is fixed by the slot geometry; the wire type is listed for discrete or ribbon cable, meaning the same housing works for both a point-to-point harness and a ribbon-cable assembly. The closed end forces the cable to load from the open side, which is a deliberate orientation key — you cannot insert the cable backwards or one position off. ## Locking Ramp and Free-Hanging Mount Mates with the standard MTA-156 pin header (0.156\" pitch, single row).","metaTitle":"TE MTA-156 3-640429-9, 9-Pos IDC Receptacle, 0.156\" Pitch","metaDescription":"TE Connectivity MTA-156 3-640429-9 receptacle, 9 positions, 0.156\" pitch, IDC termination for 24 AWG discrete or ribbon cable.","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":"White","Pitch":"0.156\\\" (3.96mm)","Series":"MTA-156","Package":"Bulk","Features":"Closed End","Wire Type":"Discrete or Ribbon Cable","Wire Gauge":"24 AWG","Row Spacing":"-","Contact Type":"Female Socket","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Receptacle","Contact Finish":"Tin","Fastening Type":"Locking Ramp","Number of Rows":"1","Product Status":"Active","lifecycle_stage":"unknown","Cable Termination":"IDC","Base Product Number":"640429","Number of Positions":"9","Contact Finish Thickness":"80.0µin (2.03µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9600","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.96000","currency":"USD"},{"qty":10,"price":"$0.91400","currency":"USD"},{"qty":25,"price":"$0.87320","currency":"USD"},{"qty":50,"price":"$0.86140","currency":"USD"},{"qty":100,"price":"$0.75260","currency":"USD"},{"qty":250,"price":"$0.72448","currency":"USD"},{"qty":500,"price":"$0.68422","currency":"USD"},{"qty":1000,"price":"$0.59165","currency":"USD"},{"qty":2500,"price":"$0.54738","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 3-640429-9?","answer":"3-640429-9 is sourced to order against an RFQ through independent distribution.
