The type (as in freq/tone) will be OK, all you have to do is see if it fits in the mount OK (if not as Chris has pointed out you just need a simple adaptor.
Please note that if you;re swapping round an LNB then please mark the centre line of the LNB (they can be rotated inside of the mount) and replace the new LNB witht he same rotaion... Just that as you go north/south from the equator the horizontal/vertical of the sat antenna is mismatched the more north/south you are
