The nickel-plated steel contact carries a 0.250\" (6.35mm) tab width and 0.032\" (0.81mm) tab thickness — the flag orientation routes the wire 90° from the tab axis, keeping the crimp body clear of adjacent terminals in a multi-position block. ## Same-width peers in the catalog The 1742543-1 shares its 0.250\" tab width and non-insulated crimp body with the Utilux-series 1-1627194-4 (15-18 AWG, brass) and the 1-1659250-0 (17-20 AWG, tin-plated brass). The 1742543-1 uses steel for the contact base — steel carries higher pull-out force at the expense of corrosion resistance versus the brass peers. The PIDG-insulated 1377175-8 (Fastin-Faston series) uses a 0.312\" tab and a pre-insulated sleeve, so it does not share the same tab width or wire range.","metaTitle":"TE 1742543-1 Faston Female Quick-Disconnect 0.250\" Tab","metaDescription":"TE Connectivity Faston 1742543-1 female quick-disconnect terminal, 16-18 AWG, 0.250\" tab width, nickel-plated steel, non-insulated flag crimp.","metaKeywords":null},"attributes":{"series":"Faston","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Wire-to-Wire Connectors","Quick-Disconnect Terminals"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"-","Gender":"Female","Series":"Faston","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"-","Tab Width":"0.250\\\" (6.35mm)","Insulation":"Non-Insulated","Tab Length":"0.305\\\" (7.75mm)","Wire Gauge":"16-18 AWG","Termination":"Crimp","Mounting Type":"Free Hanging (In-Line), Right Angle","Tab Thickness":"0.032\\\" (0.81mm)","Terminal Type":"Angled - 90°, Flag","Contact Finish":"Nickel","Product Status":"Active","lifecycle_stage":"unknown","Contact Material":"Steel","Length - Overall":"-","Base Product Number":"1742543","Insulation Diameter":"0.110\\\" ~ 0.210\\\" (2.79mm ~ 5.33mm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2600","priceTiers":[{"qty":1,"price":"$0.26000","currency":"USD"},{"qty":10,"price":"$0.22100","currency":"USD"},{"qty":25,"price":"$0.20560","currency":"USD"},{"qty":50,"price":"$0.19500","currency":"USD"},{"qty":100,"price":"$0.18430","currency":"USD"},{"qty":250,"price":"$0.17160","currency":"USD"},{"qty":500,"price":"$0.16172","currency":"USD"},{"qty":1000,"price":"$0.15324","currency":"USD"},{"qty":3500,"price":"$0.14195","currency":"USD"},{"qty":7000,"price":"$0.12853","currency":"USD"},{"qty":10500,"price":"$0.11299","currency":"USD"},{"qty":35000,"price":"$0.10099","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/952874325f536406b0cb57127bbec355.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1742543-1/alternatives.json"},"ai":{"faq":[{"question":"What is the gender of the 1742543-1 terminal?","answer":"Female.
