The closest functional second-source is the B04B-JWPF-SK-R(LF)(SN) — same 4 positions, 2.00 mm pitch, same tin-plated contacts and IP rating. The only difference is the suffix; the EK-R variant uses a different latch or packaging detail. Both are active.","metaTitle":"JST B04B-JWPF-EK-R 4-Pin Header 2mm Pitch Active","metaDescription":"JST JWPF series 4-position header, 2.00mm pitch, shrouded, latch holder, IP-rated dust-tight/waterproof.
