What this is
The B3PS-VH is the 3-circuit member of the VH series — a single-row board-to-wire header with a 0.156 inch (3.96 mm) pitch, right-angle through-hole mounting, and tin-plated brass contacts rated 10 A per circuit at 250 V. The housing is polyamide (PA66) nylon 6/6 with a UL94 V-0 flammability rating, an insulation height of 0.335 inch (8.51 mm), and an operating range of -25°C to 85°C.
Key ratings and what they mean
The 10 A per contact current rating governs power-distribution duty at this pitch — signal-level interconnects at 3.96 mm are uncommon; most VH-series applications carry load current across the header. Both mating-surface and solder-tail platings are tin — no gold option listed on this MPN, which means higher mating-cycle applications (repeated plug/unplug cycles) should evaluate whether the tin surface will hold — the series does not offer a gold-plated variant in this position count. The shrouding is 1-wall — one side of the contact cavity is covered by the housing wall, providing basic polarisation and contact protection but not full four-side encapsulation. The locking ramp on the header body mates with the receptacle housing to resist accidental unmating.
How it sits against its series peers
The B3P-VH (without the S) shares the same 3 positions, pitch, current, voltage, and tin plating but is a vertical-mount part — the right-angle orientation of the B3PS-VH is the primary footprint and board-layout difference. The two are not drop-in interchangeable in the same panel cutout. The B4PS-VH carries the same right-angle through-hole form, locking ramp, and ratings but steps to 4 positions — the only delta is circuit count. If the BOM needs four positions at the same pitch and current, the B4PS-VH is the natural series-mate.
Where this class is used
The 3.96 mm pitch VH-series header handles board-to-wire power interconnects at 10 A per circuit at 250 V — suited for in-rush and motor-drive branch circuits in industrial control, lighting, and appliance harness assemblies.
Sourcing and compliance
RoHS status is non-compliant — this part is not confirmed for EU RoHS substance restrictions. If the end product must meet EU RoHS, this MPN requires a compliance review or a sourcing alternative before being locked into the BOM. Sourced to order against BOM quantity via RFQ. Confirm the locking-ramp housing compatibility and the panel depth clearance for the right-angle profile before specifying.
