10 circuits, 4.20mm pitch, 9A per pin — the BOM-fit check
The 1-1586038-0: This is a TE Connectivity VAL-U-LOK 10-position dual-row header, 0.165" (4.20mm) pitch, rated 9A per circuit at 600VAC. The 4-wall shroud and locking ramp keep the mating receptacle seated under vibration — a step up from unshrouded pin strips common in low-cost consumer gear.
