Different AC compressor for 2.7 than 3.4?

Are the AC compressors different for the 2.7 and 3.4? For some reason I’m finding much better deals for the compressors that say they fit the 3.4 than I am for the ones that say they fit my 2.7. Curious what the difference is between the two.

 

Yes, the compressors are different:
