Male tab for solder termination
The 1742803-1 is a male quick-disconnect tab from TE's Faston series, designed for through-hole solder mounting to a PCB or bus bar. Tab measures 0.312" (7.92mm) wide and 0.030" (0.76mm) thick, with a tin-plated brass contact that suits moderate-cycle applications.
Crossing into a female receptacle
The 1742803-1 mates with female quick-disconnect receptacles of the same 0.312" (7.92mm) tab width and 0.030" (0.76mm) thickness — the 1377175-8 Fastin-Faston PIDG receptacle (14-16 AWG, crimp) shares the same tab dimensions and tin plating. A narrower 0.250" (6.35mm) female receptacle like the 1-1627194-4 Utilux will not fit this tab — the width mismatch prevents engagement.
