try fitting one on your machine- then carefully (by hand) lower the needle and see if it is going to hit the foot or not- some are interchangeble - some are not- but the basic differences are some machines are low-shank- some are high shank===and some the needle will hit and break-some will work- you will only find out if you try them- but don't just put one on and try to sew---put one on and turn the wheel by hand to lower the needle & see if it works without hitting the foot- if it does you are good to go as long as they attach securely
