Compatibility of 17.3kW 19A 1760RPM vs 15kW 16A 1769RPM Motors for Replacement

Good day
Ive got two motors one of which is currently in use and a spare but they are slightly different I was wanting to know if they were compatible??
Power  17.3kw       15kwAmps  19.0a           16.0aRPM    1760             1769Cos       0.85            0.86 
Thanks in advance

This would depend on a lot of things:- mechanical compatibility (shaft size, mounting flanges, etc- the load you are driving - if the 17.3 KW motor is near its limits, the 15KW one may not cut it and overload.- the cutout / overload  arrangements - they may need adjusting when changing from one motor to the otherWindings - I'd presume they are both 3-phase and have star-delta windings?Without a fair bit more information it's difficult to say, though they are similar in most basic respects.
