Compared to a 2-position sibling in the same NH series, this 4-position header offers the same pitch and current rating but doubles the circuit count — useful when a single connector replaces two separate 2-circuit interfaces, reducing assembly time and board real estate. Active lifecycle status — JST continues production of the NH series header under base number BS4P-SHF. RoHS compliant (LF designation confirms lead-free). The (LF)(SN) suffix indicates lead-free and tin-plated finish; the earlier BS4P-SHF-1AA (without suffix) is electrically identical but may carry different plating or packaging — confirm the BOM position before substituting. Confirm the mating receptacle part number against your wire harness specification — the NH series includes both single-row and dual-row options. Unshrouded header — no plastic shroud around the pins, so the pins are exposed. This simplifies probing but requires careful handling to avoid bending pins during mating. The insulation height of 0.220\" (5.60 mm) provides clearance for the mating receptacle's latch mechanism.","metaTitle":"JST BS4P-SHF-1AA(LF)(SN) NH Header 4-Pos 2.5mm Right-Angle","metaDescription":"JST NH series header, 4 circuits, 2.50 mm pitch, right-angle through-hole, tin plating, friction lock, UL94 V-0, RoHS.
