Here is an image showing the pin diagram of this transistor.The 2SA1403-E transistor can have a current gain of 100 to 200. The gain of the 2SA1403 will be in the range from 40 to 320, for the 2SA1403-C it will be in the range from 40 to 80, for the 2SA1403-D it will be in the range from 60 to 120, for the 2SA1403-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SA1403-E might only be marked "A1403-E".The complementary NPN transistor to the 2SA1403-E is the 2SC3597-E.You can replace the 2SA1403-E with the 2SA1096A, 2SA1184, 2SA1220, 2SA1220-Q, 2SA1358, 2SA1537, 2SA1537-E, 2SA743A, 2SA743A-C, 2SA794, 2SA794A, 2SB1144, 2SB1144-Q, 2SB1167, 2SB1167-R, 2SB1168, 2SB1168-R, 2SB548, 2SB548-Q, 2SB549, 2SB549-Q, 2SB631, 2SB631-E, 2SB631K, 2SB631K-E, 2SB649, 2SB649-C, 2SB744A, 2SB744A-O, BD138, BD138-16, BD138G, BD140, BD140-16, BD140G, BD168, BD170, BD178, BD180, BD180G, BD190, BD229, BD231, BD236, BD236G, BD238, BD238G, BD378, BD378-16, BD380, BD380-16, BD788, BD788G, BD790, BD792, KSA1220, KSA1220-O, KSB744A, KSB744A-O, KSE171, KSE172, KTA1704, KTA1704-Y, MJE171, MJE171G, MJE172, MJE172G, MJE233, MJE235, MJE250, MJE252, MJE254, MJE711 or MJE712.
