Non-insulated Faston — 0.250" tab, 18-22 AWG
The 41772: Tin-plated brass construction suits standard-duty crimp applications where the terminal is mated to a matching 0.250" male tab in a free-hanging, in-line configuration.
Wire gauge and insulation diameter range
Within the Faston series, the 41772's 18-22 AWG range and 0.090" to 0.130" (2.29mm to 3.30mm) insulation diameter sit between the 14-18 AWG 41274 (0.120" to 0.170" insulation) and the 10-14 AWG 41450 (0.150" to 0.200" insulation) — the tab width and thickness are shared across the three, so the selection axis is the wire gauge and insulation jacket the existing harness carries. The 170183-2 shares the same 18-22 AWG range and nearly identical insulation diameter but uses a 0.031" (0.79mm) tab thickness versus the 41772's 0.032" (0.81mm) — the 0.001" difference does not affect tab fit in standard 0.250" receptacles.
