Non-insulated LIF receptacle for 0.250" tabs
The 2178300-1 is the 14-18 AWG member of TE's Faston non-insulated female receptacle line, accepting 0.250" (6.35mm) wide tabs with a 0.032" (0.81mm) thickness. The low insertion force (LIF) spring design reduces mating effort without compromising retention, and the nickel-plated steel contact provides corrosion resistance in dry environments.
Wire gauge selection across the Faston 0.250" series
Within the same 0.250" tab-width Faston series, the 2178300-1 (14-18 AWG) sits between the 2178301-1 (10-12 AWG) and the 2178299-1 (18-20 AWG) — the tab dimensions, contact finish, and overall length are shared, so the choice follows the wire gauge on the harness.
