Here is an image showing the pin diagram of this transistor.The 2SB966-R transistor can have a current gain of 60 to 120. The gain of the 2SB966 will be in the range from 60 to 320, for the 2SB966-P it will be in the range from 160 to 320, for the 2SB966-Q it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SB966-R might only be marked "B966-R".The complementary NPN transistor to the 2SB966-R is the 2SD1289-R.You can replace the 2SB966-R with the 2SA1093, 2SA1104, 2SA1105, 2SA1106, 2SA1146, 2SA1186, 2SA1264, 2SA1264-O, 2SA1264N, 2SA1264N-O, 2SA1265, 2SA1265-O, 2SA1294, 2SA1301, 2SA1302, 2SA1303, 2SA1386, 2SA1386A, 2SA1386A-O, 2SA1386A-P, 2SA1386A-Y, 2SA1490, 2SA1491, 2SA1492, 2SA1516, 2SA1633, 2SA1633-D, 2SA1694, 2SA1695, 2SA1788, 2SA1788-D, 2SA1804, 2SA1805, 2SA1940, 2SA1941, 2SA1942, 2SA1943, 2SA1986, 2SA2062, 2SA2063, 2SA2120, 2SA2121, 2SA2151, 2SA2151A, 2SA2151A-O, 2SA2151A-P, 2SA2151A-Y, 2SA2223, 2SB1162, 2SB1162-Q, 2SB1163, 2SB1163-Q, 2SB1361, 2SB1361-Q, 2SB1362, 2SB1362-Q, 2SB1429, 2SB688, 2SB778, 2SB816, 2SB816-D, 2SB817, 2SB817-D, 2SB863, FJA4210, KTA1943, KTA1943A, KTA1962, KTA1962A, KTB688, KTB688B, KTB778, KTB817, KTB817-O, KTB817B, KTB817B-O, MJW1302A, MJW1302AG or NTE2329.
