Although using an equivalent transistor requires a detailed comparison, the BC547 is still a good alternative to 2N2222. BC547 transistor is considered the best equivalent of 2N2222 & can work well in your projects. Given below is the list of transistors that are equivalent to 2N2222 and can be used as a replacement. Which transistors are equivalent to 2N2222? Therefore, it is important to refer to the datasheet for the exact part number and manufacturer. The exact specifications depend on the manufacturer, case type, and variation. This table shows the technical specifications of the 2N2222 Transistor The technical specifications of 2N2222 in TO-18 metal packaging and 2N2222A transistor in TO-92 packaging are given below: Spec The Collector to Base, Emitter to Base, and Collector to Emitter voltage ratings of 2N2222 and 2N2222A are 60V, 30V, 5V and 75V, 40V, 6V respectively.Īlso, the 2N2222 comes in metal packaging whereas the 2N2222A is available in TO-92 plastic enclosure only.ĢN2222A is a better option considering its higher ratings, low cost, and TO-92 packaging. The emitter is denoted by ‘ E’.ĢN2222 VS 2N2222A: What’s the difference?īoth are similar types of transistors but the 2N2222A has higher Maximum absolute ratings than 2N2222. This pin act as an outlet and the current comes out of the transistor from here. This pin controls the transistor biasing. This pin act as an inlet as the current enters the transistor from here.
