It carries a 5.00 mm pitch, rated 7 A per circuit at 300 V, and mates with the matching WPJ receptacle housing. The header is shrouded on all four walls, with a latch holder for positive retention, and carries a waterproof ingress protection rating — suited for outdoor or washdown applications where moisture ingress is a concern. The housing is glass-filled PBT rated UL94 V-0, and the operating temperature range is -25°C to 85°C. ## Key features and ratings The 5.00 mm pitch gives enough room for the 300 V creepage without crowding the board — the 7 A per circuit rating is conservative for the contact cross-section, so the limiting factor in a harness is the wire gauge, not the header. Tin plating on both the mating and solder tails keeps the cost down; for a sealed connector that doesn't see frequent reconnection, tin is adequate. The latch holder locks the mated pair against vibration, and the four-wall shroud protects the pins during handling and misalignment. ## Mating and termination This header mates with the WPJ series receptacle housing (crimp terminal required). The through-hole solder tails are 0.130\" long, suited for standard PCB thicknesses. The board guide aids alignment during assembly. The mated stack height is 25.3 mm, which sets the z-height budget for the enclosure. ## Lifecycle and sourcing The B02B-WPJES-3 (LF)(SN) is listed as obsolete by JST. No official successor order code is recorded. Buyers should verify the mating half and circuit count before committing.","metaTitle":"JST B02B-WPJES-3 (LF)(SN) WPJ Header, 2-Pos 5.00mm, Obsolete","metaDescription":"JST B02B-WPJES-3 (LF)(SN) WPJ series header, 2 circuits, 5.00 mm pitch, 7 A, 300 V, waterproof, latch holder.
