Narrative:
During an operations check of the passenger service unit oxygen masks (drop test) we discovered l-hand #1 passenger service unit mask was not dropping. After troubleshooting; we discovered the cannon plug was damaged. Since we did not have the part in stock and the aircraft was already late; my manager instructed me to remove a passenger service unit from another CRJ200 that was in the hangar and install it on the aircraft in question. I questioned his instructions; but he told me to complete the task and to hurry. I completed switching the passenger service unit's and did an operations check. Some time later and upon further review it has come to my attention that the passenger service unit removed from the other aircraft was not applicable to the aircraft in question. The result was the aircraft had to be removed from service as soon as the discrepancy was discovered; and a new part brought in to replace the incorrect passenger service unit.
