The 0.156\" (3.96mm) pitch matches the MTA-156 header family, so the board footprint is set by that spacing. The orange housing is a visual identifier on the harness, not a functional spec. ## IDC termination and wire gauge — what fits This receptacle is specced for 18 AWG wire — that's a single gauge, so the slot width is fixed. Use the correct insulation OD for MTA-156 tooling; too thick and the wire won't seat, too thin and the grip is loose. The feed-through feature lets the wire pass straight through the housing, useful for daisy-chaining in a harness. ## Locking ramp keeps the pair mated It's a positive latch — you hear it click. For a wire-to-board connection in a moving assembly or moderate vibration, that latch holds the pair together without a secondary lock. The free-hanging mount means this receptacle is the cable side; the header is the board-mount half. ## Tin contacts — 80.0µin thick for repeated mates That's a thick tin layer — standard flash tin is around 30-50µin. The extra thickness buys more insertion cycles before the tin wears through and exposes the base metal. It's still a tin-to-tin interface, so the mating cycle life is lower than gold, but for a connector that sees occasional unmate-and-remate in service (not daily cycling), this plating is cost-effective. Tin is also the standard for MTA-156, so mixing tin receptacle with tin header is the intended match. ## Mating with the MTA-156 header The header is typically board-mount (vertical or right-angle) with the same locking ramp. The 18 AWG IDC termination is the receptacle side; the header side accepts the same gauge wire or board trace. No adapter or conversion is needed — straight MTA-156 to MTA-156.","metaTitle":"TE MTA-156 3-640599-4, 4-Pos IDC Receptacle, 0.156\" Pitch","metaDescription":"TE Connectivity MTA-156 receptacle, 4 positions, 0.156\" (3.96mm) pitch, IDC termination for 18 AWG wire, tin contacts, locking ramp.","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":"Feed Through","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":"Locking Ramp","Number of Rows":"1","Product Status":"Active","lifecycle_stage":"unknown","Cable Termination":"IDC","Base Product Number":"640599","Number of Positions":"4","Contact Finish Thickness":"80.0µin (2.03µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6200","priceTiers":[{"qty":1,"price":"$0.62000","currency":"USD"},{"qty":10,"price":"$0.59800","currency":"USD"},{"qty":25,"price":"$0.59520","currency":"USD"},{"qty":50,"price":"$0.57520","currency":"USD"},{"qty":100,"price":"$0.48230","currency":"USD"},{"qty":250,"price":"$0.45216","currency":"USD"},{"qty":500,"price":"$0.42704","currency":"USD"},{"qty":1000,"price":"$0.37428","currency":"USD"},{"qty":2500,"price":"$0.35419","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/9114e74f0d6f98f63901ed2129a98451.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/3-640599-4/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 3-640599-4 and what is the lead time?","answer":"Submit an RFQ for your BOM quantity to get a lead-time estimate."},{"question":"What is the mating connector for 3-640599-4?","answer":"The header order code starts with 640599 (the base product number) — for example, a vertical or right-angle header in the same series.
