The JST B3PS-VH is a 3-position, single-row header from the VH series, designed for board-to-cable/wire interconnects. It uses a 3.96mm pitch — wide enough to handle the 10 A per contact rating without crowding the board layout. The right-angle, through-hole orientation places the mating face parallel to the PCB, which suits low-profile harness routing or board-edge connections where a straight header would interfere with the enclosure wall.
Key features and ratings
Tin plating on both the mating surface and the solder tail keeps contact resistance stable for moderate mating-cycle duty — this is a power interconnect, not a high-cycle signal connector. The locking ramp on the shroud provides positive retention against vibration or cable tug, and the UL94 V-0 nylon housing meets the flammability requirement for equipment inside an enclosure. Operating temperature spans -25°C to 85°C, which covers most indoor industrial and consumer applications.
Comparison with the straight version
The B3P-VH shares the same 3-position count, 3.96mm pitch, and 10 A rating, but mounts straight (vertical) rather than right-angle. If your board layout has clearance for a vertical header, the B3P-VH is a drop-in alternative for the same circuit count and wire-to-board function. The B4PS-VH is the 4-position right-angle sibling — same pitch and current, one more circuit.
Lifecycle and compliance
The B3PS-VH has an Active lifecycle status. It is RoHS non-compliant per the listing — verify your assembly's regulatory requirements before committing the BOM line. No official successor or cross-reference is on record beyond the VH series siblings listed above.
