Is there a pin-compatible replacement for 100YXJ100M10X20?

Yes, several radial capacitors match the 10mm diameter and standard lead spacing. However, you must verify the case length and critical parameters like load life and ripple current before considering them fully pin-compatible.

What risks should I check before replacing 100YXJ100M10X20?

The main risk is a shorter operational lifetime, as the YXJ series has a very high load life rating (4000-10000h). Also check ripple current rating and ESR to ensure they meet your circuit's power handling needs.

100YXJ100M10X20 Alternatives, Datasheet & Cross Reference | rubycon

Finding a substitute for the Rubycon 100YXJ100M10X20 requires matching its 100µF/100V rating, radial package, and long-life characteristics. Alternatives exist but often have a shorter load life, which is a key risk to evaluate.

AI replacement insight

Electrical riskhigh

Reduced load life is a critical electrical risk. Ripple current and ESR must also be verified.

Package risklow

Several candidates match the 10mm diameter radial package, but length can vary.

Can it be replaced directly?

There is no known direct, drop-in replacement that matches all parameters, especially the high load life rating of the YXJ series. All alternatives require careful review.

Best replacement path

Use another Rubycon part like the PX series for similar quality, but verify the reduced load life is acceptable. For cost-sensitive designs, other brands offer size-compatible parts with further reduced lifetimes.

Main risk

The primary risk is reduced product reliability and lifetime due to substituting with a capacitor that has a significantly lower load life rating.

Recommended alternatives

Matches key electricals but has a shorter body and lower rated load life. From the same manufacturer.
