This works with 26-28 AWG discrete wire, and the natural-colour housing accepts the wire in a single pass. The trade-off: IDC connections are less forgiving of repeated rework than crimped terminals, so this connector is best specified for one-time harness assembly where the wire gauge and insulation diameter are controlled. The free-hanging design means it does not require a board-mount footprint — it terminates to the wire and mates to a header that is either through-hole or SMT soldered to the PCB. The single-row 9-position layout keeps the mated pair narrow, which helps when the connector sits at the edge of a crowded board or inside a shallow enclosure.","metaTitle":"TE Connectivity 173977-9 CT Receptacle, 9 Pos, 2.00mm Pitch","metaDescription":"TE Connectivity 173977-9 CT series 9-position single-row receptacle, 0.079\" (2.00mm) pitch, IDC termination for 26-28 AWG discrete wire, tin contacts.","metaKeywords":null},"attributes":{"series":"CT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 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":"9","Contact Finish Thickness":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7900","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.79000","currency":"USD"},{"qty":10,"price":"$0.76500","currency":"USD"},{"qty":25,"price":"$0.76200","currency":"USD"},{"qty":50,"price":"$0.73620","currency":"USD"},{"qty":100,"price":"$0.61730","currency":"USD"},{"qty":250,"price":"$0.57872","currency":"USD"},{"qty":500,"price":"$0.54656","currency":"USD"},{"qty":1000,"price":"$0.47904","currency":"USD"},{"qty":2500,"price":"$0.45332","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/8ac15261306a27bf454658981536441c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does the 173977-9 have a mating plug or header?","answer":"Yes, the 173977-9 receptacle mates with a CT series male header (same 2.00 mm pitch, single row).
