Hi all, I bought a IRF630 mosfet after reading a detailed introduction article about this device, here's the link: IRF630 datasheet. It gives me their comparison about specifications. But their comparative specification information is not complete. Some specification information is omitted.

The problem is after I got this device I found out that I got a IRF640 at home already, so can these two be used interchangeably?

Google the specs. As long as the gate voltage etc specs are the same you should be alright.
However the current ratings are considerably higher for the 640 so they aren't necessarily interchangeable if you substitute the 630 for the 640...
