Alternates Tool: Find Drop-in Capacitor Replacements

Find drop-in replacement capacitors ranked by DC bias performance. Input a part number and the tool will find top drop-in replacements that most closely meet the specs of the reference part ranked by DC bias derated capacitance. Alternates ranking by pricing and availability information in development.

This automates the tedious process of cross-referencing multiple manufacturer datasheets and performance curves. Verify the recommendations via the specs table and the performance graphs below. Hit the Try Me button for a demo.

Currently supporting ceramic capacitors from Murata, Kemet, TDK, Samsung, and Kyocera AVX. More manufacturers and component types coming soon.

Introducing Merlin's Changelog

We're starting this changelog to keep you up to date on new features and improvements.

The Story So Far

• The ceramic capacitor analysis tool allows engineers to easily compare specs and graphs of capacitors from Murata, Kemet, TDK, Samsung, and Kyocera AVX with detailed technical specifications and performance graphs.
• Added explanations of DC bias derating, ESR characteristics, and other critical parameters for circuit design.
• Search a single part to analyze it on its own or compare multiple parts.
