The 0039302041: This is a single-row vertical header from the Mini-Fit Jr 5566 series, with 4 positions loaded at a 4.20mm pitch.
This header mates with Mini-Fit Jr receptacle housings, such as the 5557 series, which accept crimp terminals (e.g., 5556 or 45750 series). The 4.20mm pitch and single-row layout require a matching 4-circuit receptacle housing.
