Please compare the number of pins and plugs with the old part before purchasing.
Signs that your regulator needs replacing:
Depending on the location of the regulator rectifier, the part can easily overheat. Other causes for a dead regulator rectifier center on the battery. Ground connections are important for good voltage, and if there is a faulty voltage, the regulator rectifier can run hot. Bad grounding, corroded battery connection and poor or loose battery connections will cause faulty voltage too.

There are generally two ways for the regulator rectifier to fail:
The first deals with diode burnout, resulting in battery drain. It is easy to assume that the issue is a bad battery because of symptoms such as dimming headlights and poor starts. Checking the voltage with a voltmeter versus relying on symptoms alone will prove highly beneficial. If the voltage drops below 13 volts, the motorcycle will begin to drain the battery and eventually the engine will stop. Check for bad connections and corrosion; these can also cause voltage issues.
The other failure type is shunt regulator burnout, where the regulator rectifier fails to control the voltage, resulting in battery overcharge. Again, a voltmeter will be useful for diagnosis. Though generally, readings above 17 volts mean the regulator rectifier is not converting the excess power correctly and all of that excess voltage may cause the headlights to become extremely bright and then blow.
