Is there a pin-compatible replacement for 01EC1830?

No verified pin-for-pin compatible replacement for the 01EC1830 has been identified in this analysis. All candidates require careful review of physical dimensions (package size, lead spacing) and mounting type (through-hole vs. surface mount) before use.

What risks should I check before replacing 01EC1830?

Key risks include package mismatch (radial vs. SMD, or larger can size), which impacts board fit. Also, check secondary parameters like ESR, ripple current, and load life to ensure they meet your application's requirements. Some alternatives may not have the same voltage safety margin.

01EC1830 Alternatives, Datasheet & Cross Reference | KNSCHA

KNSCHA 01EC1830 is a 33µF 50V radial aluminum electrolytic capacitor. While direct pin-compatible replacements are not readily available, several functional alternatives exist with similar electrical characteristics but may require board layout changes or have different physical dimensions.

AI replacement insight

Package riskhigh

No candidates match the target's 5x11mm radial package. All require fit checks or board redesign.

Electrical risklow

Most candidates meet or exceed key electrical specs like voltage and capacitance.

Can it be replaced directly?

No direct, drop-in replacement for 01EC1830 is confirmed. All reviewed candidates have significant differences in package size or mounting style.

Best replacement path

The most viable path is to use a larger radial capacitor like ERS1KM330F12OT if board space permits, or to redesign for an available SMD alternative.

Main risk

The primary risk is physical incompatibility. The target is a compact 5x11mm radial capacitor, and most alternatives are either larger radial parts or surface-mount components requiring a different PCB layout.

Recommended alternatives

A functional alternative with a higher voltage rating and longer life, but in a larger radial package.

Questions & answers

The best alternative depends on your design constraints. For a through-hole replacement, AISHI ERS1KM330F12OT offers upgraded voltage (100V) but is physically larger (8x12mm vs 5x11mm). If your board can be modified for an SMD part, several options like Panasonic's EEEFK2A330P exist.
