Samacsys Component Search Engine
The SamacSys Component Search Engine is a specialized platform designed to accelerate electronic design by providing engineers with free access to millions of verified CAD models. It serves as a central hub where users can find schematic symbols, PCB footprints, and 3D models (STEP files) that integrate directly into their preferred ECAD software. Key Features of the Search Engine Massive Verified Library: Access over 15 million components with high-quality, IPC-compliant symbols and footprints. Real-Time Sourcing Data: Every search result provides live pricing, stock levels, and datasheets from leading global distributors like Mouser and RS Components . 3D Mechanical Models: Most components include accurate 3D models for mechanical verification, ensuring they fit within product enclosures. Universal Compatibility: The platform supports over 24 major ECAD tools, including Altium Designer , Eagle , KiCad, Cadence OrCAD/Allegro, and Zuken . Streamlining Workflow with "Library Loader" To achieve seamless integration, SamacSys provides a free utility called the Library Loader . SamacSys: Find Any Component. Download. Design.
Here is the "long story" of the SamacSys Component Search Engine—how it started, the problem it solved, and why it became a standard in the electronics industry before its eventual integration into a larger ecosystem. The Prologue: The "Library Trap" To understand the SamacSys story, you have to understand the frustration of the modern electronics design engineer. In the world of Printed Circuit Board (PCB) design, every component—be it a resistor, a microcontroller, or a complex connector—requires three distinct things to exist in the design software:
The Symbol: The logical representation (the square box with pins that you see in the schematic). The Footprint: The physical pads on the board where the part is soldered. The 3D Model: The mechanical representation to ensure it fits in the enclosure.
For decades, creating these three elements was a manual, tedious chore known as "library creation." Engineers spent 20% to 50% of their time drawing rectangles and pads rather than actually designing circuits. Some manufacturers provided libraries, but they were often low-quality or in the wrong format. Many provided nothing. Engineers were stuck in "The Library Trap"—wasting hours on data entry. The Genesis: A Solution Born from Necessity The story begins around 2014 in the UK. A team led by Alex MacDougall recognized that the industry was shifting. Electronics were becoming more complex, and time-to-market was shrinking. Library creation was the bottleneck. They founded SamacSys with a specific mission: to provide high-quality, verified PCB libraries for free. Their business model was counter-intuitive. Instead of charging engineers for libraries, they partnered with component manufacturers (like Mouser, Digi-Key, and chip makers). The manufacturers paid SamacSys to create and host the data, because it helped engineers design their products in faster. It was a win-win: manufacturers got their parts designed in, and engineers got free, reliable data. The Engine: Building the Platform The SamacSys Component Search Engine was the technological answer to this mission. It wasn't just a website; it was an aggregator and a delivery system. Here is how it revolutionized the workflow: 1. Aggregation SamacSys built a massive database. They didn't just hoard data; they curated it. They employed engineers to manually verify footprints and symbols, ensuring that if the datasheet said a pin was 1.5mm long, the model was 1.5mm long. 2. The Search Interface The search engine was designed to be the "Google of Parts." An engineer could type in a part number (e.g., "STM32F407") and instantly see a preview. Crucially, it showed the 3D model, the symbol, and the footprint side-by-side. 3. The "Export to Anywhere" Magic The true power of the engine was its output flexibility. PCB design software (ECAD) is a fragmented market. You have Altium, KiCad, Eagle, Cadence OrCAD, and many others. Traditionally, a library file for Altium is useless to an Eagle user. SamacSys built a translation engine. Their database stored the data in a neutral format, and the website converted it on the fly. An engineer could search for a part and download it instantly for: samacsys component search engine

The Plugin Revolution While the website was great, SamacSys took another leap by developing the "Library Loader." This was a small piece of software that sat on the engineer's computer. It connected the web browser directly to the PCB software. An engineer could be on the SamacSys website, click "Download," and the Library Loader would automatically open their CAD software and place the component into their library, ready to use. It turned a 30-minute task into a 30-second task. This tool was particularly beloved by users of KiCad , an open-source software that historically lacked a unified, centralized library system. SamacSys effectively filled that gap, making professional-grade libraries accessible to hobbyists and startups. The Acquisition: Entering the NXP Fold As the Component Search Engine grew to host hundreds of thousands of parts, the company caught the eye of industry giants. In November 2021 , NXP Semiconductors (one of the world's largest chip makers) acquired SamacSys.
The Logic: NXP wanted to ensure that engineers designing with their chips had the best possible experience. By owning the library tool, they could ensure their parts were instantly usable. The Promise: NXP pledged to keep the search engine and tools free and open for all components, not just NXP parts. The SamacSys Component Search Engine is a specialized
The "Long Story" Today: ComponentSearchEngine.com Following the acquisition, the platform has continued to evolve. It is still accessible at componentsearchengine.com . However, the landscape is shifting again. Larger PLM (Product Lifecycle Management) companies are integrating these tools directly into supply chain software. SamacSys technology is now deeply embedded in the supply chain, allowing engineers to see pricing and availability alongside the symbol and footprint. The Legacy The "long story" of SamacSys is the story of removing friction. Before the Component Search Engine, the library was a wall engineers had to climb. SamacSys turned that wall into a door. They proved that in a specialized industry like electronics, a well-executed search engine and a universal file format could save millions of man-hours globally. While the company name may eventually dissolve fully into NXP's branding, the "SamacSys model"—verified, multi-format, free libraries—is now the industry standard that engineers demand.
SamacSys Component Search Engine: The Gateway to Verified Electronic Components In the world of electronic design, productivity hinges on access to accurate, high-quality data. For engineers sourcing components or building schematics, few tools are as critical—or as time-consuming to manage—as the component library. The SamacSys Component Search Engine has emerged as a leading solution to this challenge, offering a streamlined, trusted platform for finding electronic components with ready-to-use design assets. What Is the SamacSys Component Search Engine? At its core, the SamacSys Component Search Engine is a specialized web-based tool (accessible via componentsearchengine.com ) that allows engineers, purchasers, and hobbyists to search for electronic components across millions of parts. Unlike general part search engines that return only datasheets or pricing, SamacSys distinguishes itself by providing pre-built, high-quality CAD models for every listed component. These models include:
Schematic symbols (for circuit design) PCB footprints (land patterns for board layout) 3D models (for mechanical integration and visualization) Real-Time Sourcing Data: Every search result provides live
All models are available in native formats for Altium, Eagle, KiCad, OrCAD, PADS, and more . Key Features and Capabilities 1. Massive, Verified Component Database The search engine indexes millions of components from hundreds of manufacturers (e.g., Texas Instruments, Analog Devices, Microchip, Murata, TE Connectivity). Crucially, each component’s CAD models are created and verified by SamacSys’s internal engineering team , not crowd-sourced—dramatically reducing the risk of footprint errors that can cause costly board respins. 2. Direct Integration with PCB Design Tools SamacSys has partnered with major EDA vendors to embed its search engine directly into design environments:
Altium Library Loader – Search and place parts inside Altium Designer. KiCad – Built-in SamacSys plugin for direct component downloads. Eagle – Free SamaCad plugin for library management.
