I cement resistors into J-heads with exhaust putty and have never known one to fail, ever. The only reason they fail is a poor thermal connection to the heater block allowing them to run hotter than the rest of the hot end.

The standard reprap heater is 12V/40W. The resistance will be lower than your resistor, so you might want to adjust the PWM max in firmware so that you don't run it at full power, and you'll probably need to retune your PID settings.
Or do as nophead says and install it the resistor you have so that it gets good thermal contact, the only advantage of the cartridge heater is that its easier to get good contact than with an enamel resistor.
