This is fast for production but not field-reworkable — once terminated, the wire is captive. The 02SR-3S is the 2-position member of JST's SR series. The series spans from 2 to 16 positions at the same 0.039\" (1.00mm) pitch, all sharing the same IDC termination and 30 AWG wire gauge. The 03SR-3S (3-position) and 04SR-3S (4-position) are direct siblings — identical in pitch, termination, and contact finish, differing only in position count. For a 2-circuit harness, this is the minimum position count; if your BOM calls for 3 or 4 circuits, the 03SR-3S or 04SR-3S is the correct match.","metaTitle":"JST 02SR-3S SR Receptacle, 2-Pos, 1.00mm Pitch, IDC, 30 AWG","metaDescription":"JST 02SR-3S SR series 2-position receptacle, 0.039\" (1.00mm) pitch, IDC termination for 30 AWG discrete wire.
