Is there a pin-compatible replacement for 01EC0004SHG10uF250V?

No, a direct pin-compatible replacement was not found. The target part has an 8mm diameter and 3.5mm lead spacing, while all suitable electrical alternatives have a 10mm diameter and 5mm lead spacing, making them physically incompatible.

What risks should I check before replacing 01EC0004SHG10uF250V?

Before replacing, you must verify physical fit. All alternatives are larger (e.g., 10x13mm vs 8x12mm) and have different lead spacing (5mm vs 3.5mm), requiring a PCB layout change. Also, check for any downgrades in lifetime or ripple current.

01EC0004SHG10uF250V Alternatives, Datasheet & Cross Reference | KNSCHA

Finding a replacement for the KNSCHA 01EC0004SHG10uF250V, a 10µF 250V aluminum capacitor, involves a trade-off. While electrically similar or superior parts exist, none match its compact 8x12mm package and 3.5mm lead spacing, requiring board redesign for any substitution.

AI replacement insight

Package riskhigh

All candidates have a larger diameter and different lead spacing, requiring board layout changes.

Electrical risklow

Most candidates offer a higher voltage rating, which is a safe upgrade. Check ripple current on some options.

Can it be replaced directly?

No, there are no direct pin-compatible replacements available. All potential alternatives have a larger package and different lead spacing, making them physically incompatible without a board change.

Best replacement path

Use a functional alternative like Rubycon's 450BXW10MEFR10X16 for upgraded voltage and lifetime, but you must modify the PCB layout for its larger size.

Main risk

The primary risk is physical incompatibility. All candidates are larger and have a different lead spacing (5mm vs 3.5mm), which requires a PCB redesign.

Recommended alternatives

Functional alternative with higher voltage and longer life, but requires PCB change due to larger package and lead spacing.
