The mouse of all wedge and big box Amigas are interchangeable.
So one from A500 will fit and work flawlessly in one A4000T, for example. And vice-versa.
The original from A1000 is exclusive because of the L shape of the connector. All mice fit in it if no side expansion devices are used (they will block the mouse port, so only the L-shaped will fit).
CDTV & CD32 are different beasties: they use a kind of "serial" Amiga mouse.
