Electronic components are the building blocks of modern technology. They power everything from smartphones and computers to cars and aeroplanes.
However, finding the right electronic components can be a challenging and time-consuming task, even for seasoned veterans at electronics OEMs and EMSes.
In this blog post, we’ll cover practical ways to source both standard and hard-to-find electronic components, along with strategies to help you locate the parts your operation needs.
Common Channels to Find Electronic Components
When you need to find readily available electronic components, there are several options—each with distinct benefits and use cases.
1. Online Marketplaces and Distributors
Online distributors are the most popular sourcing method for electronic components for many manufacturers.
- Platforms: Digi-Key, Mouser, and Arrow Electronics.
- Advantages: Wide selection of electronic parts, consistent supply, and strong supplier relationships.
- Best for: Routine orders, established supply needs, and manufacturers looking for reliability.
2. Electronic Component Search Engines
If you want to compare sources and prices, use a component search engine.
- How it works: Enter a part number or specification, and get results from multiple sources.
- Popular options: Octopart, Findchips, and TrustedParts.
- Best for: Rapid price checks and sourcing hard-to-find parts.
3. Direct Purchases from Manufacturers
Larger buyers can often purchase directly from component manufacturers.
- Benefits: Lower costs, reliable supply, and access to custom or high-volume parts.
- Requirements: Strong supplier relationships and minimum order quantities.
- Best for: Bulk orders and custom component needs.
How to Find Hard-to-Find Electronic Components?
Obsolescence, end-of-life notices, and sudden supply chain disruptions can make certain electronic components nearly impossible to find through traditional channels. When standard distributors don’t have what you need, here are proven alternatives:
1. Excess Marketplaces
Excess marketplaces specialize in selling surplus and idle inventory from manufacturers, contract assemblers, and distributors.
- What to expect: Genuine, unused parts often still in original packaging.
- Why use them: Lower prices, quick availability, and access to obsolete or discontinued components.
Tip: Always verify part authenticity and seller reputation before purchasing.
2. Liquidation Auctions
Industrial liquidation auctions are another fast way to secure large lots of obsolete or rare electronic components.
- How it works: Sellers list surplus inventory; buyers compete for lots in a time-bound auction format.
- Why use them: Opportunity to secure below-market pricing and access inventory not listed elsewhere.
- Best for: High-volume buyers or those seeking a range of parts for ongoing maintenance needs.
3. Enterprises with Excess Inventory
Many large enterprises—especially those in electronics manufacturing, automotive, or aerospace—hold significant surplus inventory.
- How to tap in: Network with other industry players, join buyer groups, or work with industrial liquidators who connect buyers and sellers.
- Benefits: Find compatible, often unused, parts that match your specifications.
Pro tip: Use platforms or brokers specializing in matching enterprise surplus to your needs.
How to Find Alternative Electronic Components to Replace Original Parts
Parametric search in online platforms is a powerful tool that enables engineers and procurement professionals to find alternate electronic components quickly and easily. This search function enables the user to filter parts based on key technical specifications, such as voltage, current, package type, and operating temperature range, to name a few. By inputting these parameters into a search engine, the user can generate a list of components that meet their specific requirements.
To use parametric search effectively, it's essential to have a clear understanding of the technical specifications that are critical for the project.
For example, if the voltage rating is a critical factor, the user should specify the required voltage range in the search field to ensure that only relevant parts are displayed. Once the search is complete, the user can filter the results based on additional criteria, such as cost or availability, to further narrow down the list of options.
It's also important to keep an open mind when using parametric search to find alternate electronic components. While the user may have a specific part in mind, they may find that an alternate component that meets the same technical requirements offers better pricing or availability. By exploring alternate options, the user may be able to reduce the cost of the project or improve the availability of critical parts, leading to a more successful outcome.
