As I understand it: ANY Copeland residential Scroll with a '9' in that position of the model # is manufactured as a replacement compressor (not an OEM unit)... has to do with warranty tracking. AS to the internals... I do not think there is much difference... someone else might want to step in here if they know more than I do.

Your comfort, Your way, Everyday!
GA's basic rules of home heating and AC upgrades:
*Installation is more important than the brand of equipment
*The duct system keeps the house comfortable; the equipment only heats and cools (and dehumidifies)
*The value of comfort, over the long term; leave economic choices behind!
