How would we know? You gave the link to REALOEM above. Simply look up both models. Same part number means it the same item. Not sure why it matters, unless you have a stock of E46 separators to use up. This issue is in no way specific to the X5, but is common to many BMW models.

About OS, I forgot to mention something interesting: I had at home a whole OS and hoses set, Contitech brand for the hoses, Febi por the OS, that I purchased some months ago. Once I decided to replace the whole system, I wondered if it wouldn't be better to get genuine BMW parts (means supposed better quality) as this is not the job that I'd like to do every month!
So I ordered a set of brand new BMW OS and hoses and tried to do the job. It took a little more than one hour to get the old OS out, no problem except that I had to cut the old hoses (brittled) to get them out. And it took about 2 hours to only try to put the small "S" hose coming from the OS to the valve cover (the one which needs to be rotated)!! No way to click the hose on the OS, even with some silicone lubricant. It was already hard to fit with the OS outside of the vehicle and simply impossible to fit on the car... After 2 unsuccessful hours, I got the Contitech parts and immediately noticed that the design was far more better! Put them on the vehicle and after one or two tries, the hose came to the right place with no real effort...
I got a look after that to the BMW parts when I had more time. To get the hose on the OS easily, I finally needed to use a file to slightly reduce the int. diameter of the clip ring...
I don't know if it was a bad batch of parts ot whatever but it could be helpful for those who plan to replace the OS and get the same problem.
