Narrative:

Maintenance control wanted this MEL cleared on a thru flight. The lead handed me the clock which was pulled from stock. I checked our parts reference and noticed that the clock was good for the aircraft but I never realized that the #1 on the computer screen under 'position'; meant only for that position (in the airplane). Since I didn't pull the part from stock; I never checked our parts computer second screen to confirm the location of where the part is on the shelf; and on that (second) screen it clearly states that the clock is only for position #1 on the B737-300.
