Probably, but link us to the specs. Minimum - the flange-to-flange dimensions need to be the same. There could be other differences. Why are you replacing the gas valve?

I can tell you that the new replacement valve will replace both of those part numbers.

It looks like those valves are similar in design and operation. However, you would need to adjust the pilot flame as it's adjustable and possibly the main gas pressure regulator which is also adjustable.

Hopefully the valve you purchased used is working correctly.

That's basically it. I can't approve or condemn your exchange. The rest is up to you.
