PDF for the 2SC5532, 47.0 KB, indexed as a schematic and written in lowercase in the original name. The 2SC prefix is the Japanese JIS designation for NPN bipolar transistors, so this is most likely a component datasheet. No further details such as package or revision are given. Open it in a PDF viewer to identify base, collector and emitter, review breakdown voltages and gain, and evaluate replacements. Make sure the physical package and body marking match before soldering in an alternative.
