Is there a pin-compatible replacement for CGA0201C0G100J500ET?

Several capacitors share the 0201 package, but may have different electrical values. Candidates like GRM0335C1H9R0CA01D (9pF) or CGA0201C0G120J500ET (12pF) fit the PCB but require engineering review due to capacitance differences.

What risks should I check before replacing CGA0201C0G100J500ET?

Key risks include capacitance deviation, which can affect filter performance or timing circuits, and package size differences, which impact PCB layout. Always verify the substitute's datasheet for tolerance, temperature characteristics, and voltage rating.

AI replacement insight

Electrical riskmedium

C0G caps are often for precision; capacitance changes are risky.

Package riskhigh

High for functional alternates with different footprints; Low for same-package options.

Can it be replaced directly?

No exact drop-in replacement is identified in this review. Alternatives require reviewing either a capacitance change or a package change.

Best replacement path

Find a 10pF, 50V, C0G, 0201 capacitor from another major manufacturer. If unavailable, consider a part with slightly different capacitance and verify circuit impact.

Main risk

Capacitance mismatch is the primary risk, potentially altering circuit behavior in timing or filtering applications.

Recommended alternatives

Electrically identical (10pF, 50V, C0G) but in a larger 0402 package, requiring a different PCB footprint.
