Solid state overload relay on a mature Omron line
The G3S-201PL-US DC12 from Omron is a solid state overload relay sitting on the solid state relay line — the part's own listing places it under the protection / relay tree rather than the electromechanical contactor family, so it is treated as a solid-state replacement for a thermal overload block in a motor-starting string. Lifecycle is recorded as mature on this Omron code — meaning the design has long since shipped past its primary introduction window, but the part remains orderable rather than formally retired, so existing panels that specify it can still be built or maintained without an immediate re-engineering pass.
DC12 coil variant and panel-side fit
The DC12 suffix on the order code marks the coil / control-voltage variant for this G3S-201PL-US line — buyers matching a panel that already calls for a 12 VDC solid-state overload block on the relay sub-plate should specify this exact suffix rather than the AC variants, because the SSR trigger electronics on the input side are sized to that control rail.
Sourcing posture for a mature Omron SSR
For a mature-status Omron solid state relay, the realistic channel is quoted-to-order against the BOM line — independent distribution holds the part for replacement and panel-build spares, with current pricing and lot availability confirmed at RFQ rather than carried as standing shelf stock. Buyers cross-border should treat the part as documentable: country-of-origin and Omron trace paperwork travel with the shipment so the import desk can clear it under the right HS code and the receiving QA can match the nameplate against the PO line.
