Most of the time, the part number can be found on the device but but it may not be completed. For example it labels A1011, the complete part number is 2SA1011. For many parts need to add 2S prefix to complete part number. For example: Axxx, Bxxx, Cxxx, Dxxx, Kxxx will become 2SAxxx, 2SBxxx, 2SCxxx, 2SKxxx.
Sometime, the part may be burned or does not have a label, we need the model number of the equipment (in back of equipment) and the location code (on the board where the part was installed)
