Classification of hFE
The 2SD414-R transistor can have a current gain of 60 to 120. The gain of the 2SD414 will be in the range from 40 to 320, for the 2SD414-P it will be in the range from 160 to 320, for the 2SD414-Q it will be in the range from 100 to 200, for the 2SD414-S it will be in the range from 40 to 80.
Marking
Sometimes the "2S" prefix is not marked on the package - the 2SD414-R might only be marked "D414-R".
Complementary PNP transistor
The complementary PNP transistor to the 2SD414-R is the 2SB548-R.
SMD Version of 2SD414-R transistor
The 2SC3438 (SOT-89) and 2SC3438-C (SOT-89) is the SMD version of the 2SD414-R transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
