Why Choose Our Calculator?
Via Current Analysis
DigiKey's calculator focuses on trace width and impedance. We add via current capacity calculations essential for power delivery and thermal via design.
Differential Impedance
Calculate coupled differential pairs for USB, HDMI, Ethernet, and other high-speed interfaces. Critical for modern PCB designs that DigiKey's tool doesn't support.
Mobile Friendly
Fully responsive design works on any device. Check calculations during board reviews, lab work, or while traveling—something DigiKey's older interface struggles with.
About DigiKey
DigiKey Electronics is one of the world's largest electronic component distributors, headquartered in Minnesota, USA. They offer various engineering tools and calculators as free resources for their customers.
DigiKey's PCB calculators are useful but are secondary to their component distribution business. TraceWidthCalculator is dedicated entirely to PCB design calculations, which is why we offer more comprehensive features.
Use both tools together: calculate your PCB specs with TraceWidthCalculator, then source your components from DigiKey or other distributors.

Frequently Asked Questions
Are calculations the same as DigiKey?
Yes. Both use IPC-2221 standards for trace width calculations. Results should be identical for matching input parameters.
Should I still use DigiKey for components?
Absolutely! DigiKey is excellent for component sourcing. Use our calculator for PCB design, then order parts from DigiKey.
Why does our calculator have more features?
DigiKey's primary business is component distribution. Our sole focus is PCB design calculations, allowing us to offer more comprehensive tools.
Is this affiliated with DigiKey?
No. TraceWidthCalculator is an independent, free tool. DigiKey is a trademark of Digi-Key Electronics.
