In old µwave, the weak point was the capacitor (High voltage one).
The filament is too much large for dying.though is uses a large current
(some A).
A point to be checked is the cooling fan.

Hi, I have to replace (in a micorwave oven) a Panasonic magnetron 2M236-M62 which is no longer in production and it's difficult to find in my country.
Some spare parts websites list Panasonic 2M236-M42 as an alternative model, but I am unable to find the datasheets to compare values.

Any advice on where to find those datasheets, or a minimum warranty that they are compatible?

Thank you
