Voltage and size are the same, so that's good. The remaining figure,
0.13 amp, tells you how much current the component draws from the power
supply. Since 0.13 is less than 0.22, that means this fan draws less
power than the old fan. Which means that you should be able to replace
it without any danger of overloading your power supply (in fact your
power supply will have a slightly easier time with the new fan.)
So, in short, yes, it will work. However, something to check would be
the RPM of the new fan versus the old one. A slower fan won't cool as
well, and that might lead to problems of an entirely different nature
