Rated 3 A per contact at 250 V, with tin-plated mating surfaces — suitable for moderate-cycle applications where cost per position matters more than gold-plating cycle life. ## Sourcing and lifecycle status RoHS non-compliant per the listed status — verify your assembly's exemption or waiver requirements before committing the line. ## Mating and termination checklist Terminates via press-fit and solder through-hole — the press-fit tails hold the header in place during wave solder, eliminating the need for secondary hold-down fixtures. Mates with JST XA series crimp receptacle housings using the matching crimp terminal. The locking ramp on the header engages the latch on the receptacle for a vibration-resistant mate. Mated stack height is 11.3 mm — confirm the board-to-wire clearance in your enclosure before committing the layout.","metaTitle":"B03B-XASK-1-A JST XA Header 3 Pos 2.5mm Locking Ramp","metaDescription":"JST XA series header, 3 positions, 2.50mm pitch, shrouded 4-wall, locking ramp.
