A 39.6 KB PDF for the 2SC5216, with an _E tag in the name that is not explained. It is listed as a schematic, but the name points to a transistor datasheet. Parts with the 2SC prefix are NPN bipolar transistors under JIS numbering. Open it in any PDF viewer to confirm pin order, package and voltage, current and dissipation limits. Compare the board part's marking with this number, and choose substitutes with equal or higher ratings in the same case style.
