Is there a pin-compatible replacement for 01EC1266?

Yes, NJCON 47105001016R00 shares the same radial 10x16mm package and pinout. KNSCHA 03EC0563 also matches the package but has significantly lower performance and is considered a high-risk downgrade.

What risks should I check before replacing 01EC1266?

Key risks include package mismatch (SMD vs. Radial), lower ripple current handling, shorter operational lifetime, and higher ESR. Ensure any replacement meets or exceeds the target's 1400mA ripple, 5000hr life, and 0.05Ω ESR.

AI replacement insight

Electrical riskhigh

Many alternatives have much lower ripple current and lifetime ratings.

Package riskhigh

Many parametrically similar parts are SMD, not through-hole radial.

Sourcing risklow

This is a common capacitor value and package, with multiple vendors available.

Can it be replaced directly?

No verified direct drop-in replacement is available without review. The closest candidate, NJCON 47105001016R00, is an upgrade that requires engineering validation.

Best replacement path

The NJCON 47105001016R00 offers an upgrade in voltage and performance but requires verification of its lifetime and suitability of polymer capacitor chemistry.

Main risk

The main risk is selecting a substitute with inadequate ripple current handling or a shorter lifetime, which could lead to premature failure.

Recommended alternatives

A potential upgrade with higher voltage and ripple current in the same package, but requires engineering review.
