The free-hanging (in-line) mounting suits cable-to-board or cable-to-cable connections where the receptacle floats rather than being panel-mounted. The 4-position count and single-row layout must match the header's position count and row configuration — a 4-position single-row header is the correct mate.","metaTitle":"TE Connectivity 173977-4 CT Receptacle, 4-Position IDC","metaDescription":"TE Connectivity CT series 173977-4 receptacle, 4 positions, 2.00mm pitch, IDC termination for 26-28 AWG discrete wire, tin contacts, RoHS compliant, active","metaKeywords":null},"attributes":{"series":"CT","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Circular Connectors","Panel-Mount & In-Line Circular"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Natural","Pitch":"0.079\\\" (2.00mm)","Series":"CT","Package":"Bulk","Features":"-","Wire Type":"Discrete","Wire Gauge":"26-28 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":"173977","Number of Positions":"4","Contact Finish Thickness":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4400","priceTiers":[{"qty":1,"price":"$0.44000","currency":"USD"},{"qty":10,"price":"$0.40200","currency":"USD"},{"qty":25,"price":"$0.40040","currency":"USD"},{"qty":50,"price":"$0.39220","currency":"USD"},{"qty":100,"price":"$0.33520","currency":"USD"},{"qty":250,"price":"$0.30168","currency":"USD"},{"qty":500,"price":"$0.28494","currency":"USD"},{"qty":1000,"price":"$0.24974","currency":"USD"},{"qty":2500,"price":"$0.24806","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/80f6e723b8d1cc35c4ece1e666ab9241.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/173977-4/alternatives.json"},"ai":{"faq":[{"question":"Is 173977-4 RoHS compliant?","answer":"Yes, the 173977-4 is RoHS compliant."},{"question":"What is the mating connector for 173977-4?","answer":"The 173977-4 mates with a 4-position, single-row, 2.00 mm pitch CT series header (male pin strip).
