Da . BC107, 171, 337, 547 (Uce=45V), orice tranzistor care are Uce si Ic cel putin la fel ca cel indicat. Nu ai precizat la ce tensiune se alimenteaza montajul deoarece daca e la 12V (de exemplu) poti utiliza ORICE tranzistor NPN, chiar si BC108, 170 care au Uce=20V sau BC172, 238, 338 care au Uce=25V (sau oricare din BC548, 549).
