A specific one, no not really. I would suggest search for ones that have the same specs as are on the charger. It should have the info right on the charger itself. So stick with ones that have the same info.
So as an example (since I don't know what yours actually says) if it were to say it is... 20V, 3.25A, 65W ... then I would get a new one that has those same specs. Again, that is just a random example. So go with the specs listed on your charger.
