Here is an image showing the pin diagram of this transistor.The 2SD414-P transistor can have a current gain of 160 to 320. The gain of the 2SD414 will be in the range from 40 to 320, for the 2SD414-Q it will be in the range from 100 to 200, for the 2SD414-R it will be in the range from 60 to 120, for the 2SD414-S it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SD414-P might only be marked "D414-P".The complementary PNP transistor to the 2SD414-P is the 2SB548-P.The 2SC3438 (SOT-89) and 2SC3438-E (SOT-89) is the SMD version of the 2SD414-P transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SD414-P with the 2SC1565, 2SC2481, 2SC2481-Y, 2SC2690, 2SC2690-P, 2SC2690A, 2SC2690A-P, 2SC3117, 2SC3902, 2SD1684, 2SD1724, 2SD1725, 2SD415, 2SD415-P, 2SD600, 2SD600-F, 2SD600K, 2SD600K-F, 2SD669, 2SD669-D, BD169, BD237, BD237G, BD379, BD379-25, KSC2690, KSC2690-Y, KSC2690A, KSC2690A-Y, KTC2803, KTC2803-GR, MJE242, MJE244 or MJE722.
