Tin-to-tin contact with a header of the same finish is reliable for the service life of the harness; if the application requires frequent reconnection or operates in a corrosive atmosphere, a gold-plated MTA-100 variant would be the better choice.","metaTitle":"TE MTA-100 3-643816-4, 4-Pos IDC Receptacle, 0.100\" Pitch","metaDescription":"TE MTA-100 3-643816-4 4-position IDC receptacle, 0.100\" (2.54mm) pitch, tin-plated contacts, locking ramp.","metaKeywords":null},"attributes":{"series":"MTA-100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Circular Connectors","Panel-Mount & In-Line Circular"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Green","Pitch":"0.100\\\" (2.54mm)","Series":"MTA-100","Package":"Bulk","Features":"Closed End","Wire Type":"Discrete or Ribbon Cable","Wire Gauge":"28 AWG","Row Spacing":"-","Contact Type":"Female Socket","Mounting Type":"Free Hanging (In-Line), Right Angle","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":"643816","Number of Positions":"4","Contact Finish Thickness":"80.0µin (2.03µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3700","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.37000","currency":"USD"},{"qty":10,"price":"$0.33500","currency":"USD"},{"qty":25,"price":"$0.33400","currency":"USD"},{"qty":50,"price":"$0.32700","currency":"USD"},{"qty":100,"price":"$0.27940","currency":"USD"},{"qty":250,"price":"$0.25152","currency":"USD"},{"qty":500,"price":"$0.23752","currency":"USD"},{"qty":1000,"price":"$0.20819","currency":"USD"},{"qty":2500,"price":"$0.20679","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/9f03f51583de3fe9e12ef82d56d7aaf6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 3-643816-4 and what is the lead time?","answer":"Submit an RFQ for a firm commitment on your quantity."},{"question":"Is 3-643816-4 compatible with MTA-100 headers?","answer":"Yes.
