Is there a pin-compatible replacement for LS477M250O30RR0VH2SP0?

KNSCHA 152EC0330 matches the package and pinout, but its capacitance (220µF) is less than half the original's 470µF, making it unsuitable for most applications without circuit redesign.

What risks should I check before replacing LS477M250O30RR0VH2SP0?

Key risks include: 1) Capacitance mismatch, affecting circuit timing or stability. 2) Different physical size, preventing PCB fit. 3) Lower temperature or lifetime rating, reducing reliability.

LS477M250O30RR0VH2SP0 Alternatives, Datasheet & Cross Reference | Chengx

Finding a substitute for the CX LS477M250O30RR0VH2SP0, a 470µF 250V snap-in capacitor, requires checking capacitance, voltage, temperature, and physical size. Alternatives may offer higher voltage but often differ in capacitance or case dimensions.

AI replacement insight

Electrical riskhigh

Available candidates have significantly different capacitance values.

Package riskmedium

Many alternatives have different package types or dimensions.

Can it be replaced directly?

No direct, verified drop-in replacement is currently identified. All candidates require parametric or physical compromises.

Best replacement path

Search for 470µF, ≥250V, 105°C snap-in capacitors with a 25mm diameter and 10mm lead spacing. Verify case length is ≤30mm.

Main risk

The primary risk is finding a part that matches both the 470µF capacitance and the 25x30mm snap-in package.

Recommended alternatives

A form-fit alternative with significantly lower capacitance. Electrical function must be carefully evaluated before use.
