Flux Now Has the World's Largest eCAD Part Library

Scattered million of electronic components in space, with 800k super bright text at the center. This is the current number of components available at Flux today which is the largest electronic part library.

Imagine starting a project with over 800,000+ parts at your fingertips, ready to go without any setup. Gone are the days of hunting for components across multiple sites or worrying about missing parts. With Flux’s community-powered part library, you have everything you need to build at scale—all in one place, with real-time supply chain data, intelligent filters, and powerful AI tools to make part selection and optimization a breeze.

Why Library Size and Variety Matters

As any hardware designer knows, access to the right parts can make or break your design process. When the parts you need aren’t available, you’re forced to create them from scratch or search through endless online resources, slowing down your workflow and increasing the risk of mistakes.

With this launch, Flux is eliminating these obstacles. Our parts library has grown from 180,000 to over 800,000 parts this year alone, making it the largest, most comprehensive library embedded in any ECAD tool. With more parts available, you can now design faster, with greater confidence, and the reassurance that every component you need is readily available and up-to-date.

Smarter Searching and Filtering for Faster Part Selection

Finding the right part shouldn’t feel like searching for a needle in a haystack. With our expanded library, you now have access to enhanced filters and a smart ranking system that prioritizes parts based on their relevance and popularity within the community.

Here are some of the powerful filters now available in Flux:

  • Part Type – Find components based on specific categories.
  • Manufacturer – Filter by your preferred brands.
  • Mount Style – Choose parts that suit your mounting requirements.
  • Package Case Code – Select parts with the correct package type.
  • Availability – Check real-time stock status from your chosen distributor.
  • Compliance – Identify parts that meet regulatory or industry standards.
  • Terminal Count – Filter parts by the number of terminals or pins.

These filters give you the freedom to design with precision, narrowing your search to parts that fit your exact specifications and are available in real-time. No need to jump between different sources to check stock—Flux brings live data right to you.

Real-Time Data That Keeps You Ahead

The new parts library also include live data that gives you valuable insights as you build. Here’s what you’ll find:

  • Real-Time Availability and Pricing: Know exactly which parts are in stock and at what cost, so you can make informed decisions without jumping between tools.
  • Lifecycle Alerts: Receive end-of-life warnings and other lifecycle alerts right within the design canvas.helping you avoid outdated components and future compatibility issues.
  • Detailed Specs and Compliance Data: Access part specifications, compliance information, and detailed package options.

These improvements aren’t just conveniences—they’re essential tools that save you time and reduce the risk of expensive errors in your design process.

AI-Powered Workflows for Deep Research and Optimization

To help you find the best part for your project, we’ve added new, advanced filters that make selection faster and more precise. Here’s a quick summary, but check out our tutorial for a deeper dive:

  • Compare Parts Side-by-Side
    Need to weigh your options? Drag parts onto the canvas and let Copilot guide you through a side-by-side comparison, highlighting key differences and helping you make an informed choice.
  • Ask Datasheet-Specific Questions
    Save time on research by asking Copilot direct questions about datasheet information. Whether you need specs, capabilities, or compatibility details, Copilot pulls the answers you need, streamlining your design process.
  • Find Replacement Parts
    When a part is out of stock or doesn’t meet your needs, Copilot can suggest alternative components that match your requirements, keeping your project on track without manual searching.

These AI workflows allow you to optimize your BOM for factors like cost, power efficiency, and compliance—all within the same tool. It’s like having an expert assistant by your side, making every design choice easier.
