Here is an image showing the pin diagram of this transistor.The 2SA1402-C transistor can have a current gain of 40 to 80. The gain of the 2SA1402 will be in the range from 40 to 320, for the 2SA1402-D it will be in the range from 60 to 120, for the 2SA1402-E it will be in the range from 100 to 200, for the 2SA1402-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SA1402-C might only be marked "A1402-C".The complementary NPN transistor to the 2SA1402-C is the 2SC3596-C.You can replace the 2SA1402-C with the 2N4919, 2N4919G, 2N4920, 2N4920G, 2N5194, 2N5194G, 2N5195, 2N5195G, 2SA1403, 2SA1403-C, 2SA1405, 2SA1405-C, 2SA1536, 2SA1536-C, 2SA1537, 2SA1537-C, 2SA1539, 2SA1539-C, 2SB548, 2SB548-S, 2SB549, 2SB549-S, BD138, BD138-6, BD138G, BD140, BD140-6, BD140G, BD168, BD170, BD178, BD180, BD180G, BD190, BD229, BD231, BD236, BD236G, BD238, BD238G, BD378, BD378-6, BD380, BD380-6, BD440, BD440G, BD442, BD442G, BD788, BD788G, BD790, BD792, MJE233, MJE234, MJE235, MJE250, MJE251, MJE252, MJE253, MJE253G, MJE254, MJE711, MJE712 or NTE185.
