Replace Optical Drive: laptop

After spending considerable time diagnosing a problem on a friends
laptop I believe his DVD drive needs to be replaced. From what I can
tell the "lock screw tab" for lack of a better name is in different
locations on my laptop compared to where it is on his laptop drive.

Does anyone know if any slim DVD drive work or are there other
compatibility issues I should be looking out for?

Thanks in advance for any help provided.

oh and it is a fairly new Dell inspirion laptop.
