Here is an image showing the pin diagram of this transistor.The 2SA1241-O transistor can have a current gain of 70 to 140. The gain of the 2SA1241 will be in the range from 70 to 240, for the 2SA1241-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SA1241-O might only be marked "A1241-O".The complementary NPN transistor to the 2SA1241-O is the 2SC3076-O.The 2DA1213 (SOT-89), 2DA1213O (SOT-89), 2SA1213 (SOT-89), 2SA1213-O (SOT-89), 2SA1364 (SOT-89), BCP52 (SOT-223), BCP52-10 (SOT-223), BCX52 (SOT-89) and BCX52-10 (SOT-89) is the SMD version of the 2SA1241-O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1241-O with the 2SA1244, 2SA1244-O, 2SB768, 2SB906, 2SB929, 2SB929-Q, 2SB929A, 2SB929A-Q, 2SB930, 2SB930-Q, 2SB930A, 2SB930A-Q, KTA1042D or KTA1042D-O.
