8 Positions, 2.00 mm Pitch — Board-to-Wire Fit
The B8B-PH-SM4-TB(LF)(SN): This is an 8-position, single-row surface-mount header from JST's PH series, designed for board-to-wire connections. A detent lock holds the mated pair against light vibration — enough for stationary equipment but not for high-shock environments.
SMT Termination with Solder Retention
Termination is solder to surface-mount pads. The solder retention feature adds small barbs on the contact tails that grip the PCB pad during reflow, reducing tombstoning and improving shear strength against cable strain. Mated stack height is 8.6 mm — this sets the clearance between the PCB and the mating wire housing. The insulation height of 6.60 mm leaves room for the receptacle body above the board.
This part carries an active lifecycle status — JST continues to manufacture the B8B-PH-SM4-TB(LF)(SN). RoHS compliant per the (LF)(SN) suffix — lead-free and tin-plated. The base product number is B8B-PH-S, which covers the entire 8-position PH SMT family.
