The 0039299104: This header uses a 4.20mm pitch on both the mating interface and the row spacing, with two rows of 5 positions each for a total of 10 circuits. The 0.165" (4.20mm) row spacing matches the standard Mini-Fit Jr footprint — the board layout is the same as any dual-row 4.20mm header in the series.
Yes — it is a Mini-Fit Jr 5566 series header and mates with standard Mini-Fit Jr receptacle housings (e.g., 5557 series) using the 4.20mm pitch and locking ramp interface.
