Aircraft diverted into ZZZ with EPR mode fault. System showed engine 1 EPR mode fault with fault messages of P2 T2 SENS/HC/EEC1. TSM 73-XX-XX-XXX-XXX showed a P2 T2 sensor and a relay box as possible faulty Line Replaceable Unit. I looked up the part numbers for the sensor and relay box and gave those to our AOG people to see if they could find the parts in ZZZ. I think I wrote down the wrong part number for the sensor.
Technician reported ordering the wrong part for installation on an A321 aircraft.
