Here is an image showing the pin diagram of this transistor.The 2SA1402-D transistor can have a current gain of 60 to 120. The gain of the 2SA1402 will be in the range from 40 to 320, for the 2SA1402-C it will be in the range from 40 to 80, 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-D might only be marked "A1402-D".The complementary NPN transistor to the 2SA1402-D is the 2SC3596-D.You can replace the 2SA1402-D with the 2N4919, 2N4919G, 2N4920, 2N4920G, 2SA1220, 2SA1220-R, 2SA1403, 2SA1403-D, 2SA1405, 2SA1405-D, 2SA1536, 2SA1536-D, 2SA1537, 2SA1537-D, 2SA1539, 2SA1539-D, 2SA743A, 2SA743A-B, 2SB548, 2SB548-R, 2SB549, 2SB549-R, 2SB631, 2SB631-D, 2SB631K, 2SB631K-D, 2SB649, 2SB649-B, 2SB744A, 2SB744A-R, BD138, BD138G, BD140, BD140G, BD168, BD170, BD178, BD180, BD180G, BD190, BD229, BD231, BD236, BD236G, BD238, BD238G, BD378, BD380, BD440, BD440G, BD442, BD442G, BD788, BD788G, BD790, BD792, KSA1220, KSA1220-R, KSB744A, KSB744A-R, KSE171, KSE172, MJE171, MJE171G, MJE172, MJE172G, MJE233, MJE234, MJE235, MJE250, MJE251, MJE252, MJE253, MJE253G, MJE254, MJE711 or MJE712.
