What this part is
The G3R-OA202SZN-UTU 5-24VDC is an Omron solid state relay listed under the Solid State Relays category, with the subcategory reading Solid State Overload Relays inside the broader Circuit Breakers, Fuses & Protection grouping — i.e. a panel-side switching device rather than a discrete board-level component. Solid state relays in this class replace an electromechanical coil with a semiconductor output stage, so the unit switches the load with no moving contacts — quieter, faster, and tolerant of repeated cycling in heat-seal, oven, or packaging lines where mechanical relays would wear out.
Ratings on record and what they govern
The control-side input is rated 5–24 VDC, which is the coil-equivalent voltage range the integrator applies to the input terminals to command the output — the SSR draws its gate current from this rail, not from the load circuit.
Lifecycle read for the BOM line
The part sits at a mature lifecycle stage, meaning Omron has moved it past the introductory window but it has not been flagged for discontinuation — for a procurement manager this is the cohort where spot shortages surface first when demand spikes, so locking a second-source cross-reference before the next reorder cycle is the prudent move.
Sourcing posture for a line-down scenario
The mature lifecycle stage means franchise-channel allocations can thin out, and the surplus/broker channel is the realistic fallback for spot buys.
