Is there some place to look up Microwave
Magnetron Sharp 2M240G-A251 characteristics-size and is it 1250watt,
2450MHz type
(i.e can it be replacement for Magnetron Sharp 2m237-a064 )?

The answer is no, there is not some place. Like any part, you pick
the magnetron you want to use based on the specs of the product and
look at the datasheet of the replacement to see if it'll do the job.
