The real question here is why do you need a substitute? the IRF630 are still available in plentiful supply.

But to answer the question, the NTE2388 is a good substitute. As for the reasoning, compare the datasheets:

NTE2388 Datasheet - http://www.nteinc.com/specs/2300to2399/pdf/nte2388

IRF630 Datasheet - http://www.spelektroniikka.fi/kuvat/IRF630

Yes, and see if it has the same or better voltage also the same or better current...

Then s the gain about the same and the on off speed also about the same.

Finally is the intended use an amplifier with linear gain steps or a switch where the gain can much less orderly...

Now go compare the data sheets !!!
