I fixed a bad magnetron connection with the same connector but it was probably too loose. This one was tight and after cleaning the magnetron terminal I'm sure it will outlive the other parts in the microwave. It's hard to predict the lifespan of this connector, but as it's made from good materials that allow me to make a strong crimp, I'm sure it will work well. It came boxed so I can replace the other connectors in this microwave if they break later.
