Here is an image showing the pin diagram of this transistor.The 2SA1788-F transistor can have a current gain of 160 to 320. The gain of the 2SA1788 will be in the range from 60 to 320, for the 2SA1788-D it will be in the range from 60 to 120, for the 2SA1788-E it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SA1788-F might only be marked "A1788-F".The complementary NPN transistor to the 2SA1788-F is the 2SC4652-F.You can replace the 2SA1788-F with the 2SA1106, 2SA1633, 2SA1633-F, 2SB966 or 2SB966-P.
