In some cases yes, in other no.
If you can provide a lot more details about the failed drive and the donor you are trying to use, then maybe you can get more assistance.
Drive MDL, PCB codes, pics of the PCBs, etc.

fail drive mdl : WD10EARX 1.0TB (Caviar Green)
donor drive : WD5000AAKX-001CA0 (500GB)

Ok, sorry not enough details... but overall, my guess is: likely will not work.
