Crimp-on receptacle for 0.250" tabs
The 160389-3 is the 18-22 AWG member of TE's Faston non-insulated quick-disconnect receptacle line, accepting 0.250" (6.35 mm) wide tabs with 0.032" (0.81 mm) thickness. Nickel-plated steel contact material suits applications where the mating cycle count is moderate and the environment does not demand gold — the nickel finish resists corrosion at a lower cost than tin or gold plating.
Position within the 0.250" Faston range
The 160389-3's 0.250" tab width and 18-22 AWG wire range place it between the 1-1627194-4 (15-18 AWG, same tab width, brass contact, 0.780" overall length) and the 1-1659250-0 (17-20 AWG, 0.248" tab width, tin-plated brass, 0.780" overall length) — all share the same free-hanging non-insulated crimp format and 0.032" tab thickness class, so the selection axis is wire gauge and contact material.
