Here is an image showing the pin diagram of this transistor.The 2SD733K-D transistor can have a current gain of 60 to 120. The gain of the 2SD733K will be in the range from 40 to 320, for the 2SD733K-C it will be in the range from 40 to 80, for the 2SD733K-E it will be in the range from 100 to 200, for the 2SD733K-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SD733K-D might only be marked "D733K-D".The complementary PNP transistor to the 2SD733K-D is the 2SB697K-D.You can replace the 2SD733K-D with the 2N6676, 2SC1586, 2SC2428, 2SC2523, 2SD424, 2SD753 or 2SD753-B.
