Parametric IC search engine for electronic components.

A new and independent parametric IC search engine for analog IC. Our strength in IC search is the wide choice of parameters and the large variety of IC manufacturer. At present you can search 60+ analog IC manufacturer in our IC search engine. Selectable parameters are optimized for each product family. We offer up to 30+ parameter per product segment and up to 35+ parameter in the 1-page product overviews. Additional tools which help during the selection process are the product side-by-side comparison and product replacement search.

Please read our News for the latest search engine, usability and expansion updates.

Start parametric IC search and select your product group via below tiles.

Update to the manufacturer overviews. We added a checkbox in front of each product so it can be directly loaded into the side-by-side comparison. Sometimes it is hard to find out the difference between 2 products if the part number is very similar like xx1, xx2, xx3. This quick comparison should help without reading each datasheet.

2 examples are shown:

  • Manufacturer Elmos has 2 similar part numbers for its DC/DC Buck Converter: E522.01 and E522.02. Checking both parts and loading into the quick side-by-side comparision shows that one part has a fixed 3.3V output and the other has a fixed 5.0 output.

  • Manufacturer Fairchild has 5 similar part numbers for it's DC/DC LED Boost Driver: FAC5340, FAN5341, FAN5343, FAN5345, FAN5346. Checking all 5 products show that the main difference is the maximum output voltage and therefore number of LEDs each product can drive.

Changes for easier and faster usability. Instead of opening new tabs all the time to remain the present parametric search results and parameter selection, most windows open now in a lightbox. This allows a quick check for reading, datasheet opening or searching at the target page. It gives also direct access to datasheets, application notes and more - all within the manufacturers product folder and still be on the parametric search table.

The first screenshot shows which link opens in a lightbox and the other screenshots show their target pages.

  • manufacturer product folder
  • suggested inductor or inductor search tool by WE
  • Distributor inventory and pricing infomation by findchips

Note: the last 3 columns with samples, inventory and price only populate once you click the 'check inventory' button on the left menu.

Our IC search engine strengths:

  • Search: 60+ IC manufacturer ranging from small startups, over niche and special focus to the large and industry dominant manufacturer
  • Find: detailed 1-page product overviews with up to 35 parameters all on a single page
  • Compare: side-by-side comparison of up to 5 products
  • Replace: product replacement search for similar part list and search (beta)
  • rare to find and unique parameters like peak efficiency, inductor size, external component count, total solution size 
  • distributors sample, stock, inventory, pricing information for all products (beta)
  • additional resources like list of all products, help and tutorial videos, statistics, markets, parameter and manufacturer reports

 is a fast and easy parametric search engine for electronic parts and especially analog IC. With our large selection of standard plus unique technical parameters, engineers can find their ideal product within seconds and solve their application problems quickly.
