Find a cross reference
you can trust

Enter a part number to see the alternatives in our library from Chinese manufacturers, the same manufacturer and other manufacturers, then have the AI check them against the datasheets.

Letters, numbers and - . / are allowed, 2 to 80 characters. Case and spaces are cleaned up automatically.

Three steps to a cross-reference report

Submit a part number and its report opens right away.

  1. Identify the Original Part

    We find the part in our library and show its manufacturer and key specs.

    If several manufacturers use the part number, you pick one first.

  2. List known alternatives

    We list the alternatives recorded in our data, grouped by Chinese manufacturers, the same manufacturer and other manufacturers.

    Chinese manufacturers first, then by replacement level

  3. Check it with AI

    The AI compares specs and pinouts across both datasheets and cites the page numbers.

    Click “AI Replacement Review” on a candidate
Inside the Alternative Report

Known alternatives first, then an AI datasheet check

The listed alternatives come from replacement relations recorded in our data. Pinout, package and electrical specs are checked only when you run “AI Replacement Review”, which compares both datasheets item by item.

  • Manufacturer and key specs of the original part
  • The replacement type recorded in our data (direct, manufacturer recommended, etc.)
  • Three groups with counts: Chinese manufacturers, same manufacturer, other manufacturers
  • Whether each candidate has a datasheet you can open online
  • Pinout, package and specs: checked item by item in “AI Replacement Review”, with datasheet page citations

How to read replacement levels

Levels come from our data, listed from highest to lowest priority.

  1. DirectThe data source marks it as a direct replacement.
  2. MFR Recommended / UpgradeThe manufacturer's suggested successor or upgraded part.
  3. Parametric EquivalentKey specs are comparable; check pinout and package separately.
  4. Similar / OtherSame device class, for reference only; needs the most validation.

Replacement levels come from our catalog labels (Direct > MFR Recommended > Upgrade > Parametric Equivalent > Similar). They set the validation priority and do not mean a drop-in production replacement; review pinout, electrical limits, external circuitry and reliability.
