With most newer vehicles when the compressor grenades you won't get away with just changing it out...Drier/accumulator replacement and checking the expansion valve/orfice tube for debris is a must as well as flushing the system...Then hope the condenser isn't clogged after all that ... Most new compressors will have a small amount of oil but more will be needed using the service manual's recommendation for your vehicle...All new compressor should be hand turned at least 10 revolutions to expel the oil into the system before use...Don't run it too long without out a system flush or you'll be buying a new compressor again when all the metal makes it's rounds through it..
