There are only 4 or so shank lengths for sewing machines so, as long as you purchase a darning foot with the right shank for your machine, it should work. There are websites that show pictures of the different shanks and give you measurements so you can figure out what yours is (or your manual might tell you). Just Google to find one. Otherwise, take one of your Brother feet with you when you go shopping for a darning foot to make sure that the shanks are the same.
