Not what, they are not compatible.

New!! HDD-PCB.COM for all your PCB and donor HDD requirements!

so i should be looking for a 7200.11 family?

Offcourse; this is like organ donation; you dont want to put the liver of an elephant into a leapard!
Search for same familiy; exact same model and country where the drive was made; preferably same partnumber and firmware.
Must say that your chances are very slim to make this work.
Better to practise on some other drives with no important data if you would like to do it yourself.
Good luck; you'll need it.
