That means Omron still manufactures it, but it's not a new-design target — no imminent EOL notice, but also no active development. For a BOM freeze, this is a stable pick: the part has a long production history and a wide installed base, so cross-references and replacement paths are well documented. If you're planning a multi-year run, check with your sourcing desk whether a successor exists, but for current builds this is a straightforward order.
Estimated lead time is usually 1-10 working days — typical for a mature, widely stocked SSR. That's a good sign for MRO planners: you're not looking at a long backorder risk.
