XT90PB-M.G.Y is an XT90-rated alternate, but its vertical PCB mount is not a drop-in match.
XT90PW-M.G.Y replacements should be reviewed for XT90 mating, horizontal PCB footprint, and 30A/500V ratings. No pin-compatible substitute is proven from the provided data.
XT90PB ratings match; XT60 ratings conflict by source.
Horizontal footprint is not proven for kept alternates.
Passive connector; no firmware impact.
Lifecycle and PDF checks need confirmation.
No direct pin-compatible replacement is verified from these candidates.
Review XT90PB-M.G.Y only if vertical PCB mounting is acceptable; otherwise seek exact XT90PW-M.G.Y.
Mechanical fit and mating compatibility are the main risks.
