The single-row, 3-circuit layout suits low-circuit-count power taps — think a small DC fan, a sensor feed, or a battery pack lead where you need a positive, negative, and a sense or enable line.
The 4.20 mm pitch is the same across the entire Mini-Fit Jr 5557 family, so this housing mates with any 4.20 mm-pitch header in the series.
