C945: C945 transistor can also be used as an alternate of this transistor.īC557 is best complement of transistor c1815.KSP2222A: c1815 Characteristics similar to the 2N2222.It can handle more current than the C1815. This transistor is used where low power amplification is needed. There are three configuration used in an amplifier circuit are common emitter, common base, common collector. 2N4401: This is an NPN transistor suitable for applications where higher collector current is required. When its base is connected to ground it will allow high current (600mA) to pass through collector to emitter, that’s how it amplifies the current.BC547: The BC547is an NPN transistor and is often used in low-power applications.2N2222: Another NPN transistor that’s commonly used and has similar characteristics.2N3904: The 2N3904 is a widely used NPN transistor with similar characteristics to the C1815.We can replace C185 with the following transistors but pinout configuration may differ so please check if you want to use any alternate.
