What the source establishesPublished cross-reference

WorldWide Electric publishes this row in its SMR cross table, listing the WorldWide SMR model alongside competitor model numbers at the same published 25:1 cross-reference position. This preserves the manufacturer-published cross-reference claim without independently asserting that every listed competitor model is pairwise interchangeable.

Sumitomo Drive Technologies HSM307H-25 and WorldWide Electric SMR6-25/1 are tied by the published source at 25:1 · AGMA size 307.

Evidence boundary

A cross-reference is a qualified replacement lead, not proof of a drop-in swap for every configured unit.
