Here is an image showing the pin diagram of this transistor.Sometimes the "2S" prefix is not marked on the package - the 2SC4881 might only be marked "C4881".The complementary PNP transistor to the 2SC4881 is the 2SA1931.The 2SD1624 (SOT-89) and BDP949 (SOT-223) is the SMD version of the 2SC4881 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC4881 with the 2SC1985, 2SC1986, 2SC4550, 2SC4551, 2SC4552, 2SD1274, 2SD1274A, 2SD1274B, 2SD613, 2SD823, BD203, BD243A, BD243B, BD243C, BD303, BD535, BD537, BD539A, BD539B, BD539C, BD543A, BD543B, BD543C, BD545A, BD545B, BD545C, BD797, BD799, BD801, BD807, BD809, BD949, BD951, BD953, BDT81, BDT81F, BDT83, BDT83F, BDT85, BDT85F, BDX77, D44H11, D44H11FP or D44H8.
