As long as the MCU and motor chip are the same, and you swap ROM chip then it will be compatible.

Toshiba mostly give good result for PCB and head swap. Unless kill Rom when hot swap.
I do like Toshiba drives

hi friend.

is this your 1st ROM swap job then don't do it. specially toshiba 2.5 hdd. becz. Toshiba 2.5 pcb ROM swap is bit hard than 3.5 hard. overheat or any mistake, data lost forever. try with same useless PCB. or contact well experience person.

good luck

This is true, ROM chip switching isn’t so easy on these with underlying solder and easily messed up with catastrophic results

This number is all that needs to be matched to get a compatible PCB. However, as others have said, if you overheat that ROM while transferring it, it's game over forever. There's no rebuilding a destroyed Toshiba ROM, not even by professionals.

Also, how certain are you that the PCB is even at fault? It's my experience that 90% of the time people are messing around with the PCB when it has nothing to do with the root cause of the problem.
