Here is an image showing the pin diagram of this transistor.The 2SA1694-O transistor can have a current gain of 50 to 100. The gain of the 2SA1694 will be in the range from 50 to 180, for the 2SA1694-P it will be in the range from 70 to 140, for the 2SA1694-Y it will be in the range from 90 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SA1694-O might only be marked "A1694-O".The complementary NPN transistor to the 2SA1694-O is the 2SC4467-O.You can replace the 2SA1694-O with the 2SA1104, 2SA1105, 2SA1106, 2SA1186, 2SA1186-O, 2SA1294, 2SA1294-O, 2SA1303, 2SA1303-O, 2SA1386, 2SA1386-O, 2SA1386A, 2SA1386A-O, 2SA1386A-P, 2SA1386A-Y, 2SA1490, 2SA1490-O, 2SA1491, 2SA1491-O, 2SA1492, 2SA1492-O, 2SA1695, 2SA1695-O, 2SA2151, 2SA2151-O, 2SA2151A, 2SA2151A-O, 2SA2151A-P, 2SA2151A-Y, 2SA2223, 2SA2223-O, FJA4210, FJA4210R, MJW1302A, MJW1302AG, MJW21191 or MJW21191G.
