Is This The Right Diode For A Gp?

Diode
I'm attempting to repair my old GP that was damaged by a faulty power supply. I was told to replace the diode and the capacitor by the power supply input. Can I just cut the ends off this diode and solder it in?

While I'm at it how easy is it to replace a tantalum capacitor? Is this one ok? Capacitor
