Is there a pin-compatible replacement for ECE2CM100E12OTPO?

No, a pin-compatible replacement with the same 6.3mm x 12mm package has not been identified. All potential alternatives are physically larger and require a board layout check to ensure they will fit.

What risks should I check before replacing ECE2CM100E12OTPO?

The main risk is physical incompatibility. All potential replacements have a larger body diameter (from 8mm to 10mm) than the original's 6.3mm. You must measure the available space on your board. Also, check for minor differences in lifetime ratings.

Finding a replacement for the Yunxing ECE2CM100E12OTPO, a 10µF 160V capacitor in a compact 6.3mm radial package, is challenging. While several parts offer matching or superior electrical specs, they all come in larger packages that require careful physical fit verification.

AI replacement insight

Package riskhigh

All candidates are larger, especially in diameter, than the 6.3mm target part.

Electrical risklow

All kept candidates offer equal or higher voltage ratings, which is a safe electrical substitution.

Can it be replaced directly?

No direct, drop-in replacement has been verified. Several functional upgrades with higher voltage ratings are available, but all have larger physical dimensions that require verification before use.

Best replacement path

01EC0004SHG10uF250V is the most promising alternative due to its closer physical size, but still requires a fit check.

Main risk

The primary risk is the physical package size. All suitable alternatives are larger in diameter than the original part and may not fit on the circuit board.

Recommended alternatives

A 250V upgrade with a slightly larger diameter (8mm vs 6.3mm) and similar length; requires physical fit check.
