Completely different beast. Galaga takes DC in from the power supply, Galaxian takes AC in from the transformer and rectifies it to DC on the board itself (much like Pacs do).

Beyond that the pinout is different as well. You can probably get an adapter board made that will handle the pinout differences and the voltage rectification. That's assuming your Galaxian hasn't been converted over to a switching power supply... in which case you'd just need an adapter board to handle the pinout difference.
 
I put together an adapter for my Galaxian.

I mounted the Galaga board close to the front of the cabinet so I wouldn't have to stretch/flex the original harness too much. I've got a switcher wired into the adapter to power the Galaga board.

I haven't done anything to it in a long time. Galaxian is sitting ignored...
