The 2SC4632LS gets a brief 26.9 KB PDF here, indexed as a schematic but named after a discrete semiconductor. Following JIS conventions, the 2SC prefix means an NPN bipolar transistor. The LS ending appears to denote a variant of the base 2SC4632, although the name gives no details. Read the package section carefully, because suffix versions often differ in lead form or case. Match the marking and footprint on the board before using this data to source a replacement.
