Narrative:

I had removed and replaced first officer's navigation receiver with part number 622-3257-201 and installed with part number 066-1060-4B. The circumstances that led to this were in part that the crew reports of a VOR flag in view on first officer's side with 2 mins left before pushback. I, lead mechanic, was in the airplane working other items when informed. I then called a line mechanic to bring me a navigation receiver for aircraft to gate xx and installed it on #2 position. I told the mechanic that the circuit breaker was pulled. The mechanic replied to me on the radio indicating that the navigation receiver is in #2 position. I pushed back the circuit breaker and started to perform functional check of navigation receiver and upgrading to CAT IIIA status. The logbook was signed and returned to the flight crew and proceeded to handle other gate calls. The parts tag indicated that the part is for 300 series aircraft. The mechanic grabbing the part and installing it on my request. This could have been avoided by putting a flag -- not on the parts tag, which gives us a heads up as to check effectivity, thus avoiding these types of incidents from happening when there is no one to check effectivity in the office and trying to minimize delays.
