Hi Michael!
All Wii disc drives are compatible with each other.
Only the parts withing the disk drive are different (like the lasers, they use different laser). But whenever you are going to replace the whole drive, you can use all of them. You also do not have to transfer the PCB. For the Wii it's all fine and you can just swap it.
The only thing is, that the new (RVL-101) disc drive won't read gamecube games. Only the old (RVL-001) drive does.
Please let me know if you have any questions, and please let us know how it goes!
