Mated stack height is 5.6 mm, which sets the clearance needed above the board when mated with the ZH receptacle. ## Peer comparison: through-hole vs surface-mount The B2B-ZR is the through-hole version. Its surface-mount sibling, the B2B-ZR-SM4-TFT, shares the same 2-position, 1.50 mm pitch, and detent lock but adds pick-and-place features and solder retention tabs for SMT assembly. The through-hole variant offers stronger mechanical retention in high-vibration environments without the need for reflow.","metaTitle":"JST B2B-ZR Header – 2-Pos, 1.5mm Pitch, Through Hole, Active","metaDescription":"JST B2B-ZR ZH series header, 2 circuits, 1.50 mm pitch, through hole, shrouded 4-wall, detent lock, rated 1 A at 50 V.
