Product details

2.50 mm Pitch, 8 Positions — Board Footprint and Circuit Count

Mated stack height is 11.3 mm — this is the z-height from the PCB surface to the mating interface, which governs the clearance for the cable exit in the enclosure.

Through-Hole Press-Fit Termination

Termination is press-fit, solder — the header pins are designed to be pressed into plated through-holes and then wave-soldered.

8 vs 9 Positions — Position Count Decision

The sibling B09B-XASK-1 carries 9 positions on the same 2.50 mm pitch, same locking ramp, same 3 A rating, same 11.3 mm stack height. If the BOM calls for 8 circuits, this header matches; if it calls for 9, step up to the B09B-XASK-1. No other parametric difference between the two.

Frequently asked questions
