This is not usually the case. Later versions of FS will have features, like improved texture formats, that are not compatible with earlier versions. Many earlier 3rd party FS2002 aircraft were simply existing FS2000 models updated to work in the later version. In this case you might as well use the originals. I don't think proper FS2002 models will be compatible, any more than proper FS9 models are compatible with FS2002.
