CR2450 has nearly 3x the capacity of the CR2032 (620mAh vs 225mAh) so the benefit of using it is that you'll have to replace it far less frequently.
But there is a difference in physical size that one might want to double check.
That's what the name means :D
CR2032 is 20mm in diameter and 3.2mm thick.
Some smart home devices use the CR2450 rather than the CR2032.
