Here is an image showing the pin diagram of this transistor.The 2SA1313-Y transistor can have a current gain of 120 to 240. The gain of the 2SA1313 will be in the range from 70 to 240, for the 2SA1313-O it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SA1313-Y might only be marked "A1313-Y".The complementary NPN transistor to the 2SA1313-Y is the 2SC3325-Y.You can replace the 2SA1313-Y with the 2SA1518, 2SA1519, 2SA1520, 2SA1521, 2SB710A, 2SB710A-R, BCW89, FMMT2907A, FMMT2907AR, FMMT591, FMMT591Q, FMMTA55, FMMTA56, KN2907AS, KST2907A, KST55, KST56, KTN2907AS, MMBT2907A, MMBT4354, MMBT4355, MMBT4356, MMBTA55, MMBTA56, PMBT2907A, PMBTA56, PMST2907A, SMBTA55 or SMBTA56.
