What this is
The B3P-VH-FB-B is a 3-circuit single-row VH-series header with a 0.156 inch (3.96 mm) pitch, rated 10 A per circuit at 250 V, terminated as a through-hole solder part with tin-plated copper alloy contacts on both the mating face and the solder tail. The 4-wall shroud wraps all four sides of the pin array — unlike the 1-wall shroud on the plain B3P-VH — which constrains lateral entry and keeps the receptacle properly keyed in harness or panel environments where accidental skew insertion is a risk.
Ratings and what they mean
At 10 A per circuit the VH handles power-distribution bus positions cleanly at 250 V; the tin plating is adequate for this duty level, though if the application demands more than a few dozen insertion cycles the spec table carries no mating-cycle rating — treat it as a fixed-install header rather than a frequently mated interconnect. The PBT glass-filled housing carries a UL94 V-0 flammability rating and the operating window spans -25 °C to 85 °C, which covers most enclosed-panel and industrial wiring-compartment environments without derating concerns at the rated current. Insulation height is 11.00 mm from the board face — the board guide feature on the shroud helps align the mating receptacle during field service but does not change the footprint or pin assignment.
Lifecycle and sourcing
Quoted to order against BOM quantity; no official successor or cross-reference listed. Confirm the 3-circuit position count and the 4-wall shroud requirement against the existing design before committing the line.
