EHS2GM221M45OT
AISHI
Needs validationhigh risk
A functional alternative with higher voltage (400V) and much longer life, but in a larger radial package.
Best Alternatives to 152EC0251
Finding a substitute for the KNSCHA 152EC0251 capacitor requires careful attention to mechanical fit. While several parts offer matching capacitance and superior voltage ratings, none are a direct drop-in replacement due to package differences.
AI replacement insight
Package riskhigh
No candidates match the target's 16x32mm radial package, requiring PCB redesign or mechanical adaptation.
Electrical risklow
Several candidates offer superior voltage and endurance ratings, providing a safe electrical upgrade path.
Can it be replaced directly?
No direct, pin-compatible replacements were found. All suitable electrical alternatives have different physical packages.
Best replacement path
Find a 220µF capacitor with a voltage rating of 250V or higher in a radial package with a 16mm diameter and 32mm length.
Main risk
The primary risk is mechanical incompatibility. All functional alternatives are either physically larger or use a different mounting style (Snap-In).
