0.250" tab, 12-14 AWG, non-insulated
The 170089-1 is a female quick-disconnect terminal from TE Connectivity AMP Connectors' Fastin-Faston series, accepting 12-14 AWG wire with a 0.250" (6.35mm) tab width.
Same tab width, different wire range
The 170089-1's 0.250" tab width and 0.032" (0.81mm) tab thickness match the Utilux 1-1627194-4, but that peer accepts 15-18 AWG — the 170089-1 handles the heavier 12-14 AWG range.
