PDF for the 2SC5417LS, 43.1 KB, catalogued as a schematic. The LS letters after the number mark a variant of the base 2SC5417, which has its own sheet; compare both, since such suffixes often indicate a different package or lead form. Under JIS naming, 2SC identifies an NPN transistor, typically high-frequency, so this is a component datasheet. Use it to verify pinout and outline before fitting a replacement, and make sure the exact suffix on the part matches.
