Nichicon UPS2C220MPD 22µF 160V Radial Aluminum Electrolytic Capacitor Equivalent & Substitute Parts

Part Overview

The Nichicon UPS2C220MPD is a 22µF, 160V radial aluminum electrolytic capacitor rated for 2000 hours at 105°C. This component is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design support and production continuity. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts offer enhanced performance characteristics or extended operational ratings suitable for the same application space.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters: capacitance value (22µF), case diameter (10.00mm), lead spacing (5.00mm), mounting type (through hole radial), and polarization (polar). Parts are grouped into three categories based on their relationship to the main part:

Direct Equivalents maintain all electrical specifications (160V rating, 2000 Hrs @ 105°C) with identical mechanical form factor, differing only in packaging format or minor series designation.

Performance Upgrades retain the core capacitance, voltage, and mechanical dimensions but offer extended lifetime ratings (5000 Hrs or 8000 Hrs @ 105°C), higher ripple current capacity, or elevated temperature operation (125°C).

Voltage Upgrades maintain the 22µF capacitance and mechanical footprint while increasing the voltage rating (200V, 250V, or 350V), suitable for applications requiring higher voltage margin or operating in elevated voltage environments.

Engineering Selection Recommendations

Direct Replacement (Same Specifications): UPS2C220MPD1TD is a direct equivalent differing only in packaging format (cut tape versus bulk). Both parts are obsolete; however, UPS2C220MPD1TD maintains identical electrical performance and mechanical dimensions.

Recommended Active Substitutes: UCS2C220MPD (Nichicon UCS series) is the primary recommended substitute. This part is active in production, ROHS3 compliant, and offers superior performance with 8000 hours lifetime at 105°C compared to the original 2000 hours. The UCS series provides higher ripple current capacity (250 mA @ 120 Hz versus 130 mA), maintaining the same 160V rating and mechanical footprint.

Voltage-Rated Alternatives: For applications requiring higher voltage margin, UCS2D220MPD (200V) and UCS2E220MPD (250V) provide extended voltage ratings while maintaining the same 22µF capacitance and active production status. UCY2V220MPD9 offers the highest voltage rating (350V) with extended 12000-hour lifetime, suitable for demanding applications.

Temperature-Enhanced Option: UBT2C220MPD8 is designated for automotive applications with extended operating temperature range (-40°C to 125°C) and maintains the 160V rating. This part is active and ROHS3 compliant.

Alternative Manufacturer: SEK220M160ST (Cornell Dubilier Electronics) provides an active alternative from a different manufacturer with matching 22µF/160V specifications and 2000-hour lifetime. Note the reduced height (0.630" versus 0.866"), which may affect PCB layout compatibility.

Lower Lifetime Option: EKMG161ELL220MJ20S (Chemi-Con KMG series) is an active alternative with identical voltage and capacitance but reduced lifetime rating (1000 hours @ 105°C). This part is suitable only for applications with lower reliability requirements.

Frequently Asked Questions (FAQ)

Q: Can UCS2C220MPD directly replace UPS2C220MPD without PCB modification?

A: UCS2C220MPD maintains identical lead spacing (5.00mm), case diameter (10.00mm), and mounting type (through hole radial). The height difference (0.846" versus 0.866") is minimal and typically accommodated within standard PCB clearances. No PCB modification is required for electrical or mechanical compatibility.

Q: What is the primary advantage of upgrading to UCS2C220MPD?

A: The UCS2C220MPD offers 8000-hour lifetime at 105°C compared to 2000 hours for the original UPS2C220MPD, representing a 4x improvement in operational life. Additionally, ripple current capacity increases from 130 mA to 250 mA at 120 Hz, providing greater thermal margin in high-ripple applications. The UCS series is active in production, ensuring long-term availability.

Q: Are voltage-upgraded parts (200V, 250V, 350V) suitable for 160V applications?

A: Yes. Higher voltage-rated capacitors are electrically compatible with lower voltage applications. The 22µF capacitance and mechanical dimensions remain constant. Voltage upgrades provide additional safety margin and are appropriate for designs requiring future voltage headroom or operating in variable voltage environments.

Q: Why does SEK220M160ST have a different height (0.630" versus 0.866")?

A: SEK220M160ST is manufactured by Cornell Dubilier Electronics using different internal construction. The reduced height may affect PCB layout compatibility. Verify clearance requirements before substitution, particularly in space-constrained designs.

Q: Is EKMG161ELL220MJ20S suitable for long-term production use?

A: EKMG161ELL220MJ20S is active and available; however, the 1000-hour lifetime at 105°C is significantly lower than the original 2000-hour specification. This part is suitable only for applications with reduced reliability requirements or shorter operational life expectations.

Q: What compliance certifications apply to these substitute parts?

A: All listed substitute parts are ROHS3 compliant. UBT2C220MPD8 and UCY2V220MPD9 are REACH Affected; all other parts are REACH Unaffected. All parts carry EAR99 ECCN classification and HTSUS code 8532.22.0020.

Q: Can I use UBT2C220MPD8 in non-automotive applications?

A: Yes. UBT2C220MPD8 is designated for automotive applications but is electrically and mechanically compatible with general-purpose designs. The extended temperature range (-40°C to 125°C) and automotive-grade reliability provide additional performance margin for any application.
