Engineering Selection Recommendations

UCS2E220MPD (Nichicon): This substitute provides a 250 V rated voltage with identical 8000-hour lifetime at 105°C. Electrical and mechanical parameters remain unchanged from the main part. Selection is appropriate when circuit design requires voltage margin above 200 V while maintaining equivalent operational lifetime.

UCY2V220MPD9 (Nichicon): This substitute offers 350 V rated voltage with extended 12000-hour lifetime at 105°C. The higher voltage rating and extended lifetime provide design margin for demanding applications. Ripple current ratings are reduced compared to the main part. Selection is appropriate for applications requiring extended operational life or higher voltage stress tolerance.

EKXJ351ELL220MJ20S (Chemi-Con): This substitute provides 350 V rated voltage with 10000-hour lifetime at 105°C and includes AEC-Q200 automotive-grade certification. Mechanical and electrical parameters are compatible with the main part. Selection is appropriate for automotive applications or designs requiring third-party manufacturer qualification.

Frequently Asked Questions (FAQ)

Q: Can UCS2E220MPD be used as a direct replacement for UCS2D220MPD?

A: Yes. The UCS2E220MPD maintains identical capacitance, tolerance, operating temperature range, and mechanical dimensions. The 250 V rating is higher than the 200 V requirement, providing additional voltage margin. Lifetime at 105°C remains 8000 hours.

Q: What is the primary difference between UCY2V220MPD9 and UCS2D220MPD?

A: The UCY2V220MPD9 provides 350 V rated voltage (versus 200 V) and extended 12000-hour lifetime at 105°C (versus 8000 hours). All mechanical dimensions and lead spacing are identical. Ripple current ratings are lower due to the higher voltage rating.

Q: Is EKXJ351ELL220MJ20S suitable for automotive applications?

A: Yes. The EKXJ351ELL220MJ20S carries AEC-Q200 automotive-grade certification and is manufactured by Chemi-Con. It provides 350 V rated voltage and 10000-hour lifetime at 105°C with identical mechanical compatibility.

Q: Do all substitute parts fit the same PCB footprint as UCS2D220MPD?

A: Yes. All substitute parts maintain identical lead spacing (0.197" / 5.00mm), diameter (0.394" / 10.00mm), and maximum seated height (0.846" / 21.50mm). Through-hole mounting compatibility is preserved across all parts.

Q: Can a lower voltage-rated substitute be used if the circuit only requires 150 V?

A: No. Substitutes must maintain voltage ratings equal to or higher than the original part specification. Lower voltage ratings are not permitted.

Q: What is the significance of the ±20% tolerance specification?

A: The ±20% tolerance indicates the allowable capacitance variation from the nominal 22 µF value. All substitute parts maintain this identical tolerance specification, ensuring equivalent circuit performance characteristics.
