Here is an image showing the pin diagram of this transistor.The 2SC3787-R transistor can have a current gain of 100 to 200. The gain of the 2SC3787 will be in the range from 100 to 400, for the 2SC3787-S it will be in the range from 140 to 280, for the 2SC3787-T it will be in the range from 200 to 400.Sometimes the "2S" prefix is not marked on the package - the 2SC3787-R might only be marked "C3787-R".The complementary PNP transistor to the 2SC3787-R is the 2SA1477-R.You can replace the 2SC3787-R with the 2N5655, 2N5655G, 2N5656, 2N5656G, 2SC1565A, 2SC2688, 2SC2688-L, 2SC2690A, 2SC2690A-Q, 2SC2911, 2SC2911-R, 2SC2912, 2SC2912-R, 2SC3116, 2SC3116-R, 2SC3117, 2SC3117-R, 2SC3601, 2SC3601-E, 2SC3902, 2SC3902-R, 2SC3956, 2SC3956-E, 2SC4212, 2SD669A, 2SD669A-C, BD127, BD128, BD157, BD158, KSC2688, KSC2688-Y, KSC2690A, KSC2690A-O, KSE340, KTC2800, MJE340, MJE340G, MJE344, MJE3440 or MJE344G.
