Here is an image showing the pin diagram of this transistor.The 2SA1788-E transistor can have a current gain of 100 to 200. 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-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SA1788-E might only be marked "A1788-E".The complementary NPN transistor to the 2SA1788-E is the 2SC4652-E.You can replace the 2SA1788-E with the 2SA1093, 2SA1106, 2SA1146, 2SA1633, 2SA1633-E, 2SB1162, 2SB1162-P, 2SB1163, 2SB1163-P, 2SB1361, 2SB1361-P, 2SB1362, 2SB1362-P, 2SB816, 2SB816-E, 2SB817, 2SB817-E, 2SB817C, 2SB966, 2SB966-Q, KTB817, KTB817-Y, KTB817B, KTB817B-Y, MJW1302A or MJW1302AG.
