Is there a pin-compatible replacement for EGY477M1JG20RR?

No pin-compatible replacement has been verified. The closest candidate, GR477M063J20RR, has a larger 13mm diameter (vs. 10mm) and its lead spacing must be confirmed, making it unlikely to be a drop-in fit.

What risks should I check before replacing EGY477M1JG20RR?

The main risks are physical fit and secondary electricals. Check the candidate's diameter, length, and lead spacing against your PCB. Also, verify ESR, ripple current, and lifetime ratings from the datasheet.

AI replacement insight

Electrical risklow

Most candidates match or exceed key electrical ratings like voltage and capacitance.

Package riskhigh

All candidates have different physical dimensions or lead spacing, likely requiring board layout changes.

Sourcing riskmedium

Alternatives are from different manufacturers, which may have different qualification and supply chain considerations.

Can it be replaced directly?

No direct drop-in replacement has been verified. GR477M063J20RR is electrically identical but physically larger, requiring board layout verification.

Best replacement path

Verify package on electrically similar parts

Main risk

Physical incompatibility due to different package dimensions (diameter, length, lead spacing) is the primary risk across all candidates.

Recommended alternatives

Electrically similar but with a larger diameter and shorter rated lifetime; requires physical and reliability review.
