Here is an image showing the pin diagram of this transistor.The 2SD476 transistor can have a current gain of 60 to 200. The gain of the 2SD476-B will be in the range from 60 to 120, for the 2SD476-C it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SD476 might only be marked "D476".The complementary PNP transistor to the 2SD476 is the 2SB566.You can replace the 2SD476 with the 2SC1826, 2SC1827, 2SC1985, 2SC1986, 2SC2075, 2SC2334, 2SC3179, 2SC3851, 2SC3851A, 2SC789, 2SD1133, 2SD1134, 2SD1267, 2SD1267A, 2SD1269, 2SD1270, 2SD1271, 2SD1274, 2SD1274A, 2SD1274B, 2SD1355, 2SD1356, 2SD1407, 2SD1407A, 2SD1408, 2SD1568, 2SD1588, 2SD2059, 2SD2060, 2SD476A, 2SD525, 2SD526, 2SD568, 2SD569, 2SD613, 2SD743, 2SD743A, 2SD812, 2SD823, 2SD857, 2SD857A, 2SD866, 2SD866A, 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, BDT91, BDT91F, BDT93, BDT93F, BDT95, BDT95F, BDX77, D44H11, D44H11FP, D44H8, KSC2334, KSD1408, KSD1588, KSD526, KSD568, KSD569, KTD2059, KTD2060 or NTE152.
