Here is an image showing the pin diagram of this transistor.Sometimes the "2S" prefix is not marked on the package - the 2SC2530 might only be marked "C2530".The complementary PNP transistor to the 2SC2530 is the 2SA1080.The 2SC3912 (SOT-23), 2SC3913 (SOT-23), 2SC3914 (SOT-23), 2SC3915 (SOT-23), BC817 (SOT-23), BC817W (SOT-323) and BCX19 (SOT-23) is the SMD version of the 2SC2530 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2530 with the 2SC1985, 2SC1986, 2SC2075, 2SC3179, 2SC4007, 2SC4008, 2SC4550, 2SC4551, 2SC4552, 2SD1274, 2SD1274A, 2SD1274B, 2SD795, BD201, BD203, BD239, BD239A, BD239B, BD241, BD241A, BD241B, BD243, BD243A, BD243B, BD301, BD303, BD533, BD535, BD537, BD539, BD539A, BD539B, BD543, BD543A, BD543B, BD545, BD545A, BD545B, BD737, BD795, BD797, BD799, BD807, BD809, BD947, BD949, BD951, BDT29, BDT29A, BDT29B, BDT81, BDT81F, BDT83, BDT83F, BDX77, D44H11, D44H11FP or D44H8.
