The press-fit option allows solderless assembly for high-reliability backplane applications, while the solder tails provide a conventional mount. Mated stacking height is 11.3 mm, and the post length (0.134\") ensures adequate solder joint exposure on the PCB bottom side. ## Peer comparison: 8-position vs 9-position, and RoHS variants The 9-position B09B-XASK-1 is one position denser than the 8-position B08B-XASK-1(LF)(SN), sharing the same 2.50 mm pitch, locking ramp, and 3 A rating. Between the B09B-XASK-1 and its RoHS-compliant sibling B09B-XASK-1(LF)(SN), the specs are identical except for the lead-free plating on the latter. The B09B-XASK-1-A variant adds a board guide feature.","metaTitle":"JST B09B-XASK-1 XA Header – 9 Pos, 2.5 mm Pitch","metaDescription":"JST XA series 9-position shrouded header, 2.50 mm pitch, locking ramp, press-fit/solder termination.
