The MP40A is supposed to be an analog with transistor OC70 Can the MP40A be used to replace a 2N2614? |

Dear Omer, the 2N2614 is designed for a max voltage of Vce = -40 V, OC70 = -30 V, mp40a = -20 V. Because we don't know the existing voltages at the collectors of the 2N2614's in the relevant model / schematic, I can't recommend this replacement. The gain (hfe) also differs, so a Japanese type like 2SB75A, 2SB77A, 2SB178A will be more suitable. If a max voltage of -30 V will be sufficient, the AC122 may be a good choice, please take a look here, a really satisfying offer. Good luck, Günther |
