Three checks with different outcomes
RC-WM-101 has a documented successor to RC-WM-119. MC120NM has a documented RF399B system pair. Rio 4.0 v1 and v2 have an explicit revision conflict. Each result needs its own exact identifiers.
Current coverage is limited: many component identities have no documented replacement path. An Unknown result is a request for more evidence, not a recommendation to buy a similar-looking part.
