Narrative:

Pilot log item was right AC bus off light came 'on,' followed by an AC xtie lockout light. The right bus remained pwred with volts and frequencys. I contacted our technician center about the problem, the AC bus control panel was suspected to be at fault. The technician representative checked for the company part number of the AC bus control panel, which was a part number 92408, but found that it was not in stock. So he checked to see if another company part could be used in its place. He found what he thought was an optional part for the part number 92408, and he said that a part number 92432 could be used in its place, and at our station, we had found in stock. I contacted our stock room and ordered the part, which was installed. We ran the engines and accomplished the xtie checks, and checked the AC bus off light operation. All checked normal and the aircraft was released for service. Only when the direct data entry was being accomplished and the part number was entered, did the report come up, saying that the part was not configured for this aircraft. I contacted the technician representative and informed him about the part not being configured for this aircraft. Since some time had passed and the aircraft was in-flight to the next station, he said that the aircraft would be stopped, and a part number 92408 AC bus control panel would be installed in place of the part 92432, before the next flight. The company borrowed a part number 92408 AC bus control panel from another airlines and it was installed before the next flight. I found that our xref stock item store comments are sometimes misleading, especially for this particular part number.
