I wouldn't use them. Unless you are 100% certain that they are compatible I wouldn't use it. Let me put it this way, is losing your airplane worth the $5 you saved?? If you can answer yes to that question then I would say go ahead and use them. If not, then get Futaba crystals.

I know that this may sound harsh, but this is just one of the costs of being in the hobby. It just part of the cost of setting up a radio for your plane.
