Narrative:

I was answering a gate call for a popped circuit breaker. I troubleshot the problem down to a faulty flight data recorder. I looked up the appropriate part number in the ATR72 illustrated parts catalog. I was able to make out the part number partially, but not completely due to the cleanliness of the tape (unit was not completely legible). I pulled the suspected part number out of stock, proceeded to the aircraft and installed and operations checked the unit per applicable aircraft reference. No faults were noted at that time. I signed off the logbook, called in to the maintenance office to confirm status and left the aircraft as returned to service. Later, I was notified that the part number was not an approved part number for that aircraft type.
