Here is an image showing the pin diagram of this transistor.The 2SD1207-R transistor can have a current gain of 100 to 200. The gain of the 2SD1207 will be in the range from 100 to 560, for the 2SD1207-S it will be in the range from 140 to 280, for the 2SD1207-T it will be in the range from 200 to 400, for the 2SD1207-U it will be in the range from 280 to 560.Sometimes the "2S" prefix is not marked on the package - the 2SD1207-R might only be marked "D1207-R".The complementary PNP transistor to the 2SD1207-R is the 2SB892-R.The 2SC3444 (SOT-89), 2SC3444-D (SOT-89), 2SD1622 (SOT-89), 2SD1622-R (SOT-89), 2SD1623 (SOT-89), 2SD1623-R (SOT-89), 2SD874A (SOT-89), BCP55 (SOT-223), BCP55-16 (SOT-223), BCX55 (SOT-89), BCX55-16 (SOT-89), BSP41 (SOT-223) and BSR41 (SOT-89) is the SMD version of the 2SD1207-R transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SD1207-R with the 2SC2655, 2SC3328, 2SD1347, 2SD1347R, 2SD1835, 2SD1835-R or KTC3209.
