Here is an image showing the pin diagram of this transistor.The 2SA1210-S transistor can have a current gain of 140 to 280. The gain of the 2SA1210 will be in the range from 100 to 400, for the 2SA1210-R it will be in the range from 100 to 200, for the 2SA1210-T it will be in the range from 200 to 400.Sometimes the "2S" prefix is not marked on the package - the 2SA1210-S might only be marked "A1210-S".The complementary NPN transistor to the 2SA1210-S is the 2SC2912-S.You can replace the 2SA1210-S with the 2SA1407 or 2SA1541.
