S8550 can usually be directly replaced by PNP tubes such as 9012, 2N5401 and 2N2907. The power and voltage of these transistors are within the allowable ± values ​​​​of S8850, and the appearance and pin arrangement are the same. They are completely Can be replaced.

In certain circumstances, such as when implementing functions such as detection or switching, 9012, 9015, 2N5551, 3DG12, etc. can be used instead. In some circuits, the amplification requirements of S8050 are very high and cannot be replaced at will. It must be replaced with the original parameter tube, otherwise the circuit will not work properly.

Extended information:

Transistor selection and replacement:

1. First of all, make a parameter comparison. If you don’t know the parameters, you can search his specifications on the Internet first.

2. Know the parameters, especially BVCBO, BVCEO, BVEBO, HFE, ft, VCEsat parameters. Find similar products by comparing various parameters.

S8550 features:

1. Dissipation power PCM: 0.625 W (at an ambient temperature of 25°C);

2. Collector current ICM: 0.5 A;

3. Collector-base voltage V (BR) CBO: 40 V.
