Tin-plated female sockets are rated for the contact resistance of a low-cycle harness; the closed-end housing prevents wire poke-through on the last position. ## Position Count and Sibling Options The 04SR-3S sits in a single-row family that runs from 3 to 6 positions at the same 1.00 mm pitch. If the BOM calls for 4 circuits, this is the match; a 5-circuit harness steps up to the 05SR-3S without changing the wire gauge or tooling. The lifecycle status is Active and RoHS3 compliance is confirmed.","metaTitle":"04SR-3S SR Series 4-Position IDC Receptacle, 1.00mm Pitch","metaDescription":"JST SR series 04SR-3S IDC receptacle, 4 positions, 1.00mm pitch, tin contacts, 30 AWG wire.
