Here is an image showing the pin diagram of this transistor.The 2SA914 transistor can have a current gain of 90 to 450. The gain of the 2SA914-Q will be in the range from 90 to 155, for the 2SA914-R it will be in the range from 130 to 220, for the 2SA914-S it will be in the range from 185 to 330, for the 2SA914-T it will be in the range from 260 to 450.Sometimes the "2S" prefix is not marked on the package - the 2SA914 might only be marked "A914".The complementary NPN transistor to the 2SA914 is the 2SC1953.You can replace the 2SA914 with the 2SA1322.
