Component selection is the first step during schematic capture. In addition to being the most important activity of the PCBA design process, your choice of parts significantly influences the other two stages of PCBA development: manufacturing, and testing. Similarly, the sources you rely on for the procurement of components impact the entire iterative design⇒build⇒test (DBT) development cycle and can hamper board production, as well.
Where to get your electronic components is an important decision, and due diligence should be exercised before committing to a source. To help you, we have compiled a list of the top electronic component distributors based on services, experience, and expertise.
This list is based on our research on parts suppliers and their services. We based our rankings on the services offered, years in business, and a supply chain resiliency (SCR) metric with the following weighted factors:
- Availability and size of component stockpiles
- Turnaround times from manufacturers
- Counterfeit component susceptibility
- Availability of component data, datasheets, and other information
- Reputation
The factors above are derived from information available online at distributor websites and/or industry publications, and are listed according to their importance for SCR in descending order. The SCR is a quantitative ranking of our qualitative assessment of the distributor’s susceptibility to the many supply chain disruptions that can interfere with the timely and accurate delivery of electronic parts. In the table above, the higher the SCR score, the more resilient the supplier is to supply chain issues.
Summary of the Top Electronic Component Distributors
As the comparison table shows, the top electronic component distributors that made the list have a history of serving the needs of OEMs, ODMs, PCB designers, engineers, and others developers of electronic systems. However, they are distinguishable characteristics, as shown below, to help you evaluate them.
- Digi-Key
Digi-Key is the most trusted distributor of electronic components. Alternative components and other design information are available and easily accessible. Adding to their supply chain resilience is a partnership with Ultra Librarian, the largest online component library in the world for CAD models and other design data and information.
- RS-Online
RS (also known as Allied Electronics and Automation) is a highly reputable parts supplier. The company provides searchers with component quantities and design models.
- Avnet
Avnet has been around since the dawn of the electronics industry and is one of the world leaders in sales. The company provides detailed descriptions of components and datasheets that can be downloaded.
- Arrow
Arrow is another company that has evolved and grown alongside the electronics industry. The company has an integrated partnership with the industry leader for manufacturer-verified component CAD models, and provides component data, inventory, and ship dates that help streamline your component selections.
- Mouser
Mouser has developed a large following and is known for providing many alternatives for common components. They provide listed lead times to assist you in choosing among the available options.
- WPG
Although a relatively new company, WPG is rated as the second-largest electronics distributor in the world. The company has operations in many countries, which improves availability. However, the data and inventory information for online searchers is limited.
Choosing the Best Component Distributor
The global market for consumer electronics exceeds one trillion USD. Consequently, there is a sizable number of vendors and distributors of electronic components to choose from. With supply chain issues such as shortages and delays plaguing developers throughout the industry, making this choice is more critical now than ever. Partnering with an industry leader that sources from reliable electronics manufacturers, provides manufacturer-vetted CAD models, and services, such as a custom library built to your specifications and requirements, is probably your best choice. Doing so ensures the foundation of your design and development process is quality components, accurate data, and supply chain resilience.
