There are two different gear series of this product.
If replacing just the gearhead and not the motor, look for a GU or GE on the gearhead you are replacing and pick the corresponding gear type series.
If replacing both gearhead and motor together, opt for the GE versions of this product which are the current specification versions from the manufacturer. Product names are the same but with GE instead of GU in the name.
Compatible with 90W Induction Motors.
