Is there a pin-compatible replacement for ERS1HM680E12OT?

No pin-compatible replacements have been verified. Candidates with matching electrical values often differ in package size, lead spacing, or mounting type (SMD vs. Through-Hole), requiring layout changes.

What risks should I check before replacing ERS1HM680E12OT?

The main risks are physical and electrical. Verify the substitute's package size (diameter, length, lead spacing) fits your PCB. Electrically, ensure capacitance is identical, and voltage rating is equal or higher. Also check endurance and ESR if critical for your application.

AI replacement insight

Package riskhigh

Most alternatives have different dimensions or mounting types.

Electrical risklow

Candidates with matching capacitance and equal/higher voltage are available.

Can it be replaced directly?

No, a direct drop-in replacement for ERS1HM680E12OT has not been found. All candidates require some level of design review.

Best replacement path

Use a functional alternative like ERS1KM680G13OT, but verify the larger package and lead spacing fit the PCB layout.

Main risk

The primary risk is physical incompatibility. Many functional alternatives have different package sizes, lead spacing, or are surface-mount instead of through-hole.

Recommended alternatives

AISHI ERS1KM680G13OT is a functional alternative with higher voltage but requires layout verification.
