I think it is difficult to say yeasts are equivalent. Even liquid yeasts that are supposed to be from the same source sometimes are much different.
I have heard people say that BRY-97 is the dry equivalent of WY1272. I have used both a lot and they are very different. I have heard the Belle Saison and WY3711 are equivalent. Again I have used both a lot and they give much different flavor profiles. They do share the trait that they will ferment the spoon if you stir too long, but they are definitely different.
So maybe instead of saying they are equivalent, say they are somewhat similar and can be used as a possible substitution.
