The through-hole termination uses press-fit solder tails, and the natural PA66 insulator is rated UL94 V-0. The tin-on-tin contact finish — both mating and post — suits applications where mating cycles are moderate and cost is a factor.
At 16 positions, this is the highest circuit count in the single-row XH header family — the B15B-XH-A carries 15 positions, one fewer. The 2.50mm pitch is wider than the 2.00mm or 1.25mm found on compact wire-to-board connectors, which means more board space per circuit but easier routing and less risk of solder bridges during hand assembly.
