Can I use a hard drive PCB from a different manufacturer as a replacement?

No, you cannot use a hard drive PCB from a different manufacturer as a replacement. Hard drive PCBs are designed to work specifically with the hard drive they were manufactured for, and they are not interchangeable between different hard drive models or manufacturers. Even if the PCB appears to be identical, there may be differences in the firmware or other components that can cause compatibility issues. Using a PCB from a different manufacturer can result in data loss or damage to the hard drive. It is important to always use a replacement PCB that is designed for your specific hard drive model and revision number (hard drive pcb replacement).
