The Basic Principles Of Component Selection

With the development of science and technology, the types and functions of electronic components are becoming more and more perfect, and the branches are gradually expanding. But the selection of components has also become a technical task. Many new people will take a lot of detours when they are just entering the industry or when they are just designing PCB boards, and they can't suffer a lot of losses. Today I will present you with the selection of components. I hope I can give you some help~

Electronic Component

With the development of science and technology, the types and functions of electronic components are becoming more and more perfect. However, the selection of components has also become a technical task. When many small partners just enter the industry or design PCB boards, they will take many detours and suffer a lot of losses. Today, the editor will introduce to you the basic principles of component selection, and hope to give you some help~

The principle of universality:

      If the selected components have been widely used and verified, try to minimize the use of unpopular and partial chips to reduce development risks.

Substitution principle:

      Try to choose components with more pin to pin compatible chip brands.

The principle of high cost performance:

      In the case of similar functions, performance, and utilization rates, try to choose components with better prices to reduce costs.

Principles of sustainable development:

      Try to choose components that will not be discontinued in the foreseeable time.

Principles of resource conservation:

      Try to use all the functions and pins of the components.

Principles of Convenience in Purchasing:

      Try to choose components that are easy to buy and have a short lead time.

Principle of upward compatibility:

      Try to choose components that have been used in old products before.

Familiar with these basic principles of component selection, you can confidently and boldly buy components against the principles! Hope it can help you!
