It mates to 0.110\" (2.79mm) or 0.125\" (3.18mm) tab widths with a 0.032\" (0.81mm) tab thickness, and the tin-plated brass contact suits moderate-cycle applications where corrosion resistance is not the primary concern. ## Tab width and wire range versus Utilux and PIDG peers The 2-520979-2's 0.110\" (2.79mm) tab width and 18-22 AWG wire range differ from the wider 0.248\" (6.30mm) tab of the Utilux 1-1659250-0 (17-20 AWG) and the 0.250\" (6.35mm) tab of the Utilux 1-1627194-4 (15-18 AWG) — the narrower tab and smaller wire gauge target signal-level circuits rather than power distribution. The PIDG 1377175-8 (0.312\" tab, 14-16 AWG) is a heavier-duty terminal with non-mating end insulation; the 2-520979-2's fully insulated barrel provides complete coverage along the wire entry.","metaTitle":"TE 2-520979-2 Quick-Disconnect Terminal, 18-22 AWG, Red","metaDescription":"TE Connectivity Ultra-Fast Plus 2-520979-2 female quick-disconnect terminal, 18-22 AWG, 0.110\" tab width, tin-plated brass, fully insulated, ROHS3 compliant.","metaKeywords":null},"attributes":{"series":"Ultra-Fast Plus","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Wire-to-Wire Connectors","Quick-Disconnect Terminals"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Red","Gender":"Female","Series":"Ultra-Fast Plus","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"-","Tab Width":"0.110\\\" (2.79mm), 0.125\\\" (3.18mm)","Insulation":"Fully Insulated","Tab Length":"-","Wire Gauge":"18-22 AWG","Termination":"Crimp","Mounting Type":"Free Hanging (In-Line)","Tab Thickness":"0.032\\\" (0.81mm)","Terminal Type":"Standard","Contact Finish":"Tin","Product Status":"Active","lifecycle_stage":"unknown","Contact Material":"Brass","Length - Overall":"0.735\\\" (18.67mm)","Base Product Number":"520979","Insulation Diameter":"0.060\\\" ~ 0.120\\\" (1.52mm ~ 3.05mm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3400","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.34000","currency":"USD"},{"qty":10,"price":"$0.30600","currency":"USD"},{"qty":25,"price":"$0.30480","currency":"USD"},{"qty":50,"price":"$0.29840","currency":"USD"},{"qty":100,"price":"$0.25510","currency":"USD"},{"qty":250,"price":"$0.22960","currency":"USD"},{"qty":500,"price":"$0.21686","currency":"USD"},{"qty":1000,"price":"$0.19007","currency":"USD"},{"qty":3000,"price":"$0.18879","currency":"USD"},{"qty":6000,"price":"$0.16966","currency":"USD"},{"qty":15000,"price":"$0.15787","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/2-520979-2","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/2-520979-2 when reusing this data.
