What risks should I check before replacing 01EC4236?

Check for physical fit (diameter, length, lead spacing), electrical parameters beyond the basics (ESR, ripple current, lifetime), and temperature range to ensure reliability in your application.

01EC4236 Alternatives, Datasheet & Cross Reference | KNSCHA

Find and compare alternatives for the 01EC4236, a 470µF 50V radial aluminum electrolytic capacitor. This guide reviews pin-compatible options, functional alternatives, and potential risks.

AI replacement insight

Package riskhigh

Many functional alternatives have different packages (SMD, Snap-in) or sizes that will not fit.

Electrical riskmedium

Secondary parameters like ESR, ripple current, and lifetime must be verified from datasheets.

Sourcing risklow

This is a common capacitor value with many available manufacturers.

Can it be replaced directly?

Direct replacement for 01EC4236 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The GR477V050G20RR0VH4FP0 from CX is the strongest candidate, matching key electrical specs and package size, making it a potential pin-to-pin replacement after verifying secondary parameters.

Main risk

The main risk is physical incompatibility. Many alternatives have different package sizes, mounting types (SMD), or lead spacing, requiring PCB redesign.

Recommended alternatives

A strong pin-to-pin candidate with matching key electrical specs and package dimensions.
