12-speed Shimano HG cassettes
Every cassette here mounts on a Shimano HG (8-11sp MTB) body and shifts 12 speeds. Two of the three things that decide a cassette, then — what's left is the chain family it needs, the gearing range you want, and that your rear derailleur can wrap it.

These all mount and all shift the right number of gears, but they split across chain families that don't interchange — the chain and rear derailleur have to match the one you pick. Check which your bike runs before ordering.
