KKM Solutions does not publish a manufacturer lifecycle status for 18637 — check Schneider Electric's own product page for whether it is current, superseded, or end-of-life. It does not change what we can do: we source current-production, superseded and long-obsolete parts the same way, and where a part is genuinely unavailable we identify a form-fit-function equivalent.
