Narrative:
On aircraft X; an aircraft support mechanic replaced a halon fire extinguisher. As a lead; I made the logbook entry for the extinguisher that was replaced. The extinguisher was not the correct extinguisher for this aircraft resulting in a configuration deviation. This could have been prevented by checking the extinguisher effectivity to the aircraft. Supplemental information from acn 817018: I was completing the safety check on aircraft X. I found a fire extinguisher with the date unreadable. We replaced the fire extinguisher with the same type that was on the aircraft. Fire extinguisher was not effective for that aircraft; resulting in a configuration deviation.
