BC548 equivalent transistor is the topic we are going explain here, when we were working with an electronic circuit, the replacement for a component is an important thing we always follow.

If it is on circuit designing or upgrading of a circuit, sometimes we need a replacement component, especially for transistors. In these situations, we must have considered so expectations of the transistor.

So in this post, we are going to explain about different specifications expects of the BC548 equivalent transistor and also suggest a perfect equivalent for the BC548 NPN BJT transistor.
