I've never found the need to use any force at all. Always a snug fit, but easily achievable by hand.
It sounds to me that the tolerances on the new part might be at the extent of here they should be.
As Plieades suggests, it might be a burr, or excess paint (if it has been painted - I can't tell) - worth checking and giving each spline a gently rub with a needle file to clean it back.
Or
You could try heating the new sprocket up a little (boiling water), the expansion might be enough, but then to get it off you are going to have to heat it up. I'd be inclined to return it and get another one.
Worth checking the splines on the drive shaft over, one
may be damaged - but it doesn't look it from the photo.
I certainly wouldn't use force to get it on.
