Quick-disconnect receptacle, 0.250" tab
The 175164-1: It crimps onto 14-18 AWG wire and hangs free in-line; the steel contact carries no insulation sleeve.
Tab-width selection in the Positive Lock EX line
The 175164-1 uses a 0.250" tab width, while the 175034-1 and 175032-1 in the same series use a narrower 0.187" tab — the wire gauge range and overall length differ accordingly, so the tab width must match the mating male blade.
