Can I replace a transistor with any other transistor?

Fortunately it is normally possible to use a replacement transistor type as there is often a considerable degree of overlap between the specifications of different types of transistor, and by looking at the basic specifications it is normally possible to choose the correct transistor replacements.

What is beta for a 2N3904 transistor?

For your transistor, the ubiquitous 2N3904, Fairchild’s datasheet quotes a minimum beta of 100 and a typical of 300 at 10mA collector current and 1V from collector to emitter.

What are the three leads in the 2N3904 NPN transistor?

The 2N3904 is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, base, and collector leads. Here is an image showing the pin diagram of the this transistor. Complementary PNP transistor

What kind of transistor is the UTC 8550?

UNISONIC TECHNOLOGIES CO., LTD 8550S PNP SILICON TRANSISTOR LOW VOLTAGE HIGH 3 CURRENT SMALL SIGNAL 1 PNP TRANSISTOR 2 SOT-23 DESCRIPTION The UTC 8550S is a low voltage high current small signal PNP transistor, designed for Class B push-pull audio amplifier and general purpose applications.

How does the s8550 PNP transistor datasheet work?

Note: Complete Technical Details can be found at the S8550 transistor datasheet given at the end of this article. S8550 is a PNP transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin.
