Here is an image showing the pin diagram of this transistor.The 2SB1429-R transistor can have a current gain of 55 to 110. The gain of the 2SB1429 will be in the range from 55 to 160, for the 2SB1429-O it will be in the range from 80 to 160.Sometimes the "2S" prefix is not marked on the package - the 2SB1429-R might only be marked "B1429-R".The complementary NPN transistor to the 2SB1429-R is the 2SD2155-R.You can replace the 2SB1429-R with the 2SA1294, 2SA1302, 2SA1302R, 2SA1386A, 2SA1386A-O, 2SA1386A-P, 2SA1386A-Y, 2SA1492, 2SA1943, 2SA1943R, 2SA1962, 2SA1962R, 2SA1986, 2SA2121, 2SA2121-R, 2SA2151, 2SA2151A, 2SA2151A-O, 2SA2151A-P, 2SA2151A-Y, 2SA2223, 2SA2223A, FJA4213, FJA4213R, FJL4215, FJL4215R, KTA1943, KTA1943A, KTA1943AR, KTA1943R, KTA1962, KTA1962A, KTA1962AR, KTA1962R, MAG9413, MJW1302A, MJW1302AG or NTE2329.
