The current rating is not a single fixed value — it varies by wire gauge, as the smaller 22 AWG conductor has higher resistance and will heat more under load than 20 AWG. For a harness designer, this means the actual current per contact depends on the wire size selected; the 250V voltage rating is consistent across the range. The free-hanging design allows the connector to be used as a cable-end receptacle without a backshell, though a backshell kit can be added for strain relief and shielding termination if the application requires it.","metaTitle":"TE 1-745491-9 AMPLIMITE HDE-20 D-Sub Receptacle, 9 Pos IDC","metaDescription":"TE Connectivity 1-745491-9 AMPLIMITE HDE-20 D-sub receptacle, 9 positions, IDC termination for 20-22 AWG, gold-plated contacts, 250V rating.","metaKeywords":null},"attributes":{"series":"AMPLIMITE HDE-20","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["D-Sub & D-Shaped Connectors","D-Sub Cable Assemblies"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Black","Series":"AMPLIMITE HDE-20","Package":"Bulk","Features":"-","Wire Gauge":"20-22 AWG","Termination":"IDC, Discrete Wire","Contact Form":"-","Contact Type":"Signal","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Receptacle, Female Sockets","Contact Finish":"Gold","Flange Feature":"Housing/Shell (Unthreaded)","Number of Rows":"2","Product Status":"Active","Voltage Rating":"250V","Backset Spacing":"-","Connector Style":"D-Sub","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Ingress Protection":"-","Base Product Number":"745491","Dielectric Material":"Thermoplastic, Glass Filled","Number of Positions":"9","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-55°C ~ 105°C","Shell Material, Finish":"Steel, Tin Plated","Contact Finish Thickness":"30.0µin (0.76µm)","Material Flammability Rating":"UL94 V-0","Shell Size, Connector Layout":"1 (DE, E)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.5900","priceTiers":[{"qty":1,"price":"$8.59000","currency":"USD"},{"qty":10,"price":"$7.48700","currency":"USD"},{"qty":25,"price":"$7.28960","currency":"USD"},{"qty":50,"price":"$7.09280","currency":"USD"},{"qty":100,"price":"$6.65930","currency":"USD"},{"qty":250,"price":"$6.61992","currency":"USD"},{"qty":500,"price":"$6.22588","currency":"USD"},{"qty":1000,"price":"$5.55600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/026933f092cb679b1c2eadb0af3d3cd7.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1-745491-9/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the TE 1-745491-9 D-sub receptacle?","answer":"The 1-745491-9 is sourced to order through independent distribution.
