Tin-plated female socket contacts are standard; tin is adequate for the limited mating cycles typical of an internal harness that is mated once and left in place. The housing is natural (uncolored) UL-rated material, free-hanging (in-line) with no mounting ears — it floats in the harness, not panel-mounted. ## What the IDC Termination Means for Your Build IDC on discrete wire requires a specific hand-tool or press — the same tooling used for the CT series ribbon connectors works, but the wire must be aligned individually into each slot. The 26-28 AWG range is narrow; 24 AWG is too thick for the slot geometry, and 30 AWG may not be reliably captured. The single-row layout (13 positions in one row) means the harness exit is a flat ribbon-like spread, which simplifies routing in a shallow enclosure.","metaTitle":"TE CT 1-173977-3 Receptacle, 13 Pos, 2.00mm IDC","metaDescription":"TE Connectivity CT 1-173977-3 receptacle, 13 positions, 0.079\" (2.00mm) pitch, IDC termination for 26-28 AWG discrete wire, tin contacts, active production","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":"13","Contact Finish Thickness":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5100","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.51000","currency":"USD"},{"qty":10,"price":"$1.38100","currency":"USD"},{"qty":25,"price":"$1.34080","currency":"USD"},{"qty":50,"price":"$1.32700","currency":"USD"},{"qty":100,"price":"$1.23180","currency":"USD"},{"qty":250,"price":"$1.21136","currency":"USD"},{"qty":500,"price":"$1.10248","currency":"USD"},{"qty":1000,"price":"$0.98678","currency":"USD"},{"qty":2500,"price":"$0.91192","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/a1c0865492628e892d86688ab5941416.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 1-173977-3 and what is the price?","answer":"Submit an RFQ for the exact BOM quantity."},{"question":"What is the pitch of 1-173977-3?","answer":"The pitch is 0.079\" (2.00mm), which is the standard CT-series spacing for signal-level discrete-wire harnesses."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/1-173977-3","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/te-connectivity-amp-connectors/1-173977-3 when reusing this data.
