The 2.50mm pitch sets the PCB footprint and the per-contact current ceiling — at 3A the temperature rise stays within the UL94 V-0 nylon 6/6 housing rating. The natural insulation color and glass-filled PA66 material are standard for general-purpose wire-to-board interconnects. ## 26 positions vs 22 — choosing the right circuit count The B26B-XADSS-N-A carries 26 circuits in a dual-row layout. The sibling B22B-XADSS-N offers 22 positions on the same 2.50mm pitch and row spacing, same vertical orientation, same locking ramp. If your BOM calls for 26 positions, this is the one; if 22, the B22B-XADSS-N is the direct drop-in. Both are active, both use tin-plated mating contacts rated 3A per circuit at 250V. The only functional difference is the position count — no change in footprint width or mating height.","metaTitle":"B26B-XADSS-N-A JST XAD Header, 26 Pos, 2.5mm, Through Hole","metaDescription":"JST XAD series 26-position vertical header, 2.50mm pitch, shrouded 4-wall, locking ramp, rated 3A/250V.
