VH Series 3-Position Header, 3.96mm Pitch
The JST B3P-VH-FB-B(LF)(SN) is a 3-position, single-row header from the VH series, designed for board-to-cable/wire interconnects. It carries a 0.156" (3.96mm) pitch, which gives enough clearance for the 10 A per-contact rating without requiring an unusually wide board footprint. The through-hole solder termination and shrouded 4-wall design with a locking ramp make it a direct-fit choice for harness assemblies where the mating half needs positive retention against vibration.
What the Ratings Mean for Your Fit
Position Count Comparison: 3 vs 2
This B3P-VH-FB-B(LF)(SN) is the 3-position variant of the VH series. The 2-position sibling, B2P-VH-FB-B(LF)(SN), shares the same 0.156" (3.96mm) pitch, 10 A rating, 250 V rating, tin plating, shrouding, and locking ramp. The only decision-relevant difference is the position count — match the circuit count on your BOM. If your design calls for exactly 3 circuits, this is the one; the 2-position version won't fit a 3-circuit harness without adding a separate connector.
Sourcing and Compliance
The B3P-VH-FB-B(LF)(SN) carries an Active lifecycle status and is RoHS Compliant, so there's no end-of-life pressure for new designs or ongoing production. The UL94 V-0 flame rating on the housing satisfies the flammability requirement for equipment inside an enclosure.
