Murata Electronics
Electrically similar but in a larger 0402 package, requiring a different PCB layout.
Reviewing alternatives for the Murata GRM0335C1H820JA01D, an 82pF 50V 0201 C0G capacitor. Key considerations for substitutes are capacitance value and package size.
All same-package candidates have different capacitance values.
One candidate is in a larger 0402 package, requiring a PCB change.
No direct pin-to-pin replacements were found. All candidates have different capacitance values or package sizes.
Evaluate candidates with the closest capacitance, like GRM0335C1H750GA01D (75pF), but circuit testing is required.
The primary risk is a change in circuit behavior due to capacitance mismatch. A package mismatch requires a PCB redesign.
