Is there a pin-compatible replacement for KCXL4502W101MF?

A pin-compatible replacement has not been verified. While some alternatives are radial leaded, their physical dimensions and lead spacing must be checked against the target part's footprint to ensure they fit.

What risks should I check before replacing KCXL4502W101MF?

Key risks to check are: 1) Voltage rating must be at least 450V. 2) Capacitance changes can affect performance (e.g., hold-up time, inrush current). 3) Physical dimensions (diameter, length, lead spacing) must fit the PCB layout.

KCXL4502W101MF Alternatives, Datasheet & Cross Reference | Ymin

Finding a substitute for the Ymin KCXL4502W101MF, a 100µF 450V radial aluminum electrolytic capacitor, requires careful matching of voltage, capacitance, and physical size. Alternatives exist but often involve parametric trade-offs.

AI replacement insight

Electrical riskhigh

Capacitance mismatch can affect circuit timing, stability, and inrush current.

Package riskhigh

Candidates have different dimensions and lead types (e.g., snap-in) that may not fit the PCB.

Sourcing risklow

Multiple manufacturers produce capacitors with similar ratings, though parameters vary.

Can it be replaced directly?

No direct drop-in replacement has been identified. All potential alternatives require engineering review due to significant differences in capacitance and/or package dimensions.

Best replacement path

Select a candidate with a 450V rating and evaluate if its capacitance (e.g., 68µF or 180µF) is acceptable for the specific application after circuit analysis.

Main risk

The main risks are circuit malfunction from mismatched capacitance and mechanical incompatibility due to different package sizes or lead types.

Recommended alternatives

Matches voltage but has much higher capacitance (180µF) and a larger, potentially snap-in package.
