Was there any serious opposition to the Habsburg dynasty for the Imperial throne between the death of Frederick III and the War of the Austrian Succession (1493-1740)?

After Frederick III managing secure the title of Holy Roman Emperor(several Habsburgs have been king of the romans beforehand), was there any serious opposition for the Habsburg election to the imperial throne until the succession of Maria Theresa?
