Replacement ECM motor RPM difference

My current ECM 3/4 horsepower motor is rated at 1050 RPM. Genteq provides two replacement motors for my specific model, ALL with the same specifications except for the RPM, one is rated at 1050 and the other at 1075. I'm having a difficult time finding the 1050rpm motor in stock (6207x), but finding ample supply of the other 1075 RPM rated motor (6207E). Since it is an ECM motor and the difference in RPM is only 2% and it's listed as compatible, is it acceptable to use the 1075 RPM motor?
