Hardware engineers usually care about the following issues when designing circuits ：

Whether the inventory of this component is sufficient , Can you supply goods stably for a long time ;
Is this component popular , Whether there will be unexpected problems , Usually, the more people use the components, the less easy it is to step on thunder ;
Is the price of this component reasonable ;
Is this component made in China , Is there any domestic one that can replace , Usually, the price of domestic products is lower , Shorter delivery time ;
Where can I download this component data manual .

The following websites can provide comprehensive information when used together , Including component data manual download and supply .

Abstract

The star rating of the website is based on my personal frequency of use and subjective feelings , Not very authoritative , All students make their own judgments .

One . Domestic component mall

1.1 Li Chuang mall

Li Chuang mall _ Electronic components procurement online mall _ Leading spot component trading platform - Jialichuang electronic mall (szlcsc.com)

I use Lichuang mall most everyday , Relatively complete components , Data manuals are provided , You can also learn about inventory information .

1.2 Huaqiu Mall

Huaqiu Mall ( primary " Huaqiang core city ") Official website _ Electronic components procurement network _ Self operated spot electronic components mall - One stop electronic components mall (hqchip.com)

Huaqiu mall is also a relatively large electronic component mall in China , Provide data manuals .

1.3 Quick match PCB

PCB Proofing _ Circuit board proofing _ Agile speed PCB Super factory (jiepei.com)

Quick match PCB It is a strong competitor of Lichuang in all aspects , You can search the stock and data manual respectively .

These three are basically the largest component mall in China , The models are quite complete , If you can't find inventory information or data manuals on these three websites , You can try your luck on the following websites .

1.4 Cloud core city

Cloud core city ICKey.cn_ Electronic components procurement _BOM Match the order _SMT Patch _PCB Proofing

Yunhan core city feels that it is the best in the second tier of component mall .

1.5 Between cores

In Xinjian mall - Genuine electronic components 、SMT Patch 、PCB customized 、BOM The table is equipped with a single station service platform (zxjian.com)

Between cores , Accidentally found a website , Looking at the inventory, I feel there are quite a lot of goods .

1.6 Shenghetang online

Shenghetang's one-stop component e-commerce platform - Shenghetang online (bomman.com)

Shenghetang online , In Zhihu see components mall , It feels a little more reliable than some miscellaneous shopping malls .

1.7 Other domestic component malls

The following malls are relatively small , Are developing .

Two . Foreign component mall

2.1 Tradeze Electronics

Electronic components distributor - Mouser Electronics

Advantages of MAOZe Electronics ：

The screening design of components is good , It can easily screen out components that meet the requirements
Schematic symbols are provided for most components 、PCB Encapsulation and data manual
It can be seen that the components are out of production 、 Not recommended for information such as new designs , Remind designers to avoid using

shortcoming ：

Only foreign components
It may be because the server is abroad , Very slow to visit
Now in chip shortage , Many component inventories show 0

I used to use Mao Ze more , After the rise of Li Chuang in recent years, it is less used , But when using foreign components, it is still very good to use maize electronics to obtain various information of components .

2.2 Dejie Electronics

Dejie Electronics China Digi-Key Official website | The supplier directly authorizes the distributor of electronic components (digikey.cn)

Like MAOZe Electronics , Dejie is also a large foreign component mall , The information is also very complete , But it is not convenient to use .

2.3 Jiechi electron

Jiechi Electronics Co., Ltd - Global electronic component dealers _IC_ The transistor _ Capacitance resistance (jotrin.com)

It is smaller than MAOZe and Dejie , The web page is also a little poor .

3、 ... and . Data manual download website

The above component stores provide data manuals to download , Most components can be downloaded through the mall .

The following website is a pure data manual download website , The data is relatively complete , Data manuals of some niche components can also be found .

3.1 Semi conducting core

Semi conducting core - Chip query tool _ Chip replacement query _ Data book query _ Specification inquiry _datasheet Inquire about _IC Inquire about (semiee.com)

Famous chip inquiry website in China , Wechat applet and APP, It is developing well now , The chip data is quite complete .

3.2 Core check

Core check - Electronic information industry data engine (xcc.com)

It is also famous in China , There are also APP.

3.3 Core mining net

Core mining net FindIC- Electronic components query ,datasheet download , Electronic components search engine

Domestic development of hot components information inquiry website , Benchmarking foreign websites ——Datasheets, Electronic Parts, Components, Search - Octopart.

This website has AIBOM The function of , Can recognize BOM Intermediate components and give suggestions , For example, which material is discontinued .
