halacha - Is there a "5 second rule" for foods becoming non-Kosher?

OK so I don't actually mean a 5 second rule. But is there an amount of time that it takes for something hot that comes in contact with a non-Kosher utensil or surface to become not kosher? For example, if something falls out of my frying pan and touches the range surface (which is not Kosher as it is constantly getting splattered by milchig and fleishig), and I grab it right away, is it too late?

I'll CMLOR for any practical real-life scenarios.
