    Hi,
    it all depends really...and the best place to look for the info is probably the manufacturer datasheet.
    For example, we are using 2 legged and 3 legged crystal here and the difference between them is whether they have built-in capacitors.

    I am convinced that a 4 pin crystal has 1 or 2 of its pin not connected anywhere....
    to be checked...
