Is there a pin-compatible replacement for CY2102MD14EF44G2A8?

No direct pin-compatible replacement with identical 7.5mm lead spacing was identified in this review. All suitable electrical alternatives have different package dimensions, requiring mechanical checks before use.

What risks should I check before replacing CY2102MD14EF44G2A8?

The main risks are mechanical fit and safety compliance. Verify the substitute's lead spacing (e.g., 10mm vs. 7.5mm) fits your PCB. Also, ensure the safety class (e.g., Y1, Y2, X2) is appropriate for your application's safety requirements.

CY2102MD14EF44G2A8 Alternatives, Datasheet & Cross Reference | Dersonic

Finding a substitute for the Dersonic CY2102MD14EF44G2A8 Y2 safety capacitor involves checking key safety and mechanical parameters. While several parts offer similar capacitance and even upgraded safety ratings, differences in lead spacing are common and require verification.

AI replacement insight

Electrical risklow

Many candidates offer superior voltage and safety ratings.

Package riskhigh

All suitable alternatives have a wider 10mm lead spacing vs. the original 7.5mm.

Can it be replaced directly?

No direct, drop-in replacement was found. All candidates require mechanical verification due to different lead spacing.

Best replacement path

Upgrade to a Y1-rated capacitor with a higher voltage rating, but verify mechanical fit for the wider lead spacing.

Main risk

Package mismatch (lead spacing) is the primary risk, preventing a direct drop-in replacement.

Recommended alternatives

Electrically stronger (Y1, 400V) but has different lead spacing (10mm vs 7.5mm).
