Hi, The replacement for my current motor is listed as UST1072. It seems the only difference from the ST1072 is the service factor. Can I use an ST1072 instead of a UST1072 or is the service factor a game breaker?

The ST1072 is a stronger motor so you may need to change the impeller if it was originally set up for the UST1072. Also the filter may not be able to handle the extra water pressure.
