UVR2D221MHA Equivalent & Substitute Parts

Part Overview

The UVR2D221MHA is a 220 µF, 200 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete and no longer recommended for new designs. The UVR series represents an older generation of general-purpose aluminum electrolytic capacitors with a rated lifetime of 2000 hours at 85°C.

Finding equivalent and substitute parts is necessary due to the obsolete status of this component. Direct replacements from the same manufacturer series and cross-manufacturer alternatives are available with improved specifications, enhanced compliance certifications, and extended operational temperature ranges.

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Specifications):

UVR2D221MHD (Nichicon) provides the closest direct equivalent with identical 220 µF, 200 V ratings and matching physical dimensions. This part carries ROHS3 compliance, addressing the RoHS non-compliance of the original UVR2D221MHA. Product status is "Not For New Designs," indicating limited future availability.

ESMG201ELL221MMP1S (Chemi-Con) offers an active-status alternative with identical electrical specifications and ROHS3 compliance. Physical height is 1.457" versus 1.476" for the original, representing a 0.019" reduction that remains within typical PCB clearance tolerances for through-hole components.

B43821A2227M000 (EPCOS - TDK Electronics) provides extended lifetime performance at 3000 hours @ 85°C compared to the original 2000 hours, with ROHS3 compliance and active product status. Physical height matches the Chemi-Con alternative at 1.457".

For Enhanced Performance (Extended Temperature Range):

UAQ2D221MHD (Nichicon) maintains 220 µF, 200 V specifications while extending the operating temperature range to -40°C ~ 105°C and lifetime to 2000 hours @ 105°C. This part carries active product status and ROHS3 compliance, providing superior thermal performance for applications requiring extended temperature operation.

EKMG201ELL221MMP1S (Chemi-Con) offers identical electrical specifications to UAQ2D221MHD with extended 105°C temperature capability. Product status is "Discontinued at DiGi Electronics," indicating potential supply constraints.

For Upgraded Voltage Rating (250 V):

UVK2E221MHD (Nichicon), 250PK220MEFC18X35.5 (Rubycon), ESMQ251ELL221MMP1S (Chemi-Con), and EKMQ251ELL221MMP1S (Chemi-Con) all provide 250 V rated alternatives with 220 µF capacitance. These parts maintain identical physical form factors and lead spacing while offering increased voltage margin. All carry ROHS3 compliance.

250PX220MEFC18X35.5 (Rubycon) combines 250 V rating with extended 105°C temperature operation, providing maximum performance enhancement while maintaining mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use a 250 V rated capacitor in place of the 200 V UVR2D221MHA?

A: Yes. A higher voltage rating maintains full electrical compatibility. The 250 V alternatives (UVK2E221MHD, 250PK220MEFC18X35.5, ESMQ251ELL221MMP1S, EKMQ251ELL221MMP1S) provide identical 220 µF capacitance and matching physical dimensions while offering increased voltage margin. This substitution is electrically valid and mechanically compatible.

Q: What is the difference between parts with 85°C and 105°C temperature ratings?

A: The temperature rating indicates the maximum continuous operating temperature at which the capacitor maintains its specified lifetime. Parts rated for 105°C operation (UAQ2D221MHD, EKMG201ELL221MMP1S, EKMQ251ELL221MMP1S, 250PX220MEFC18X35.5) provide extended performance in higher-temperature environments. For applications operating at or below 85°C, both 85°C and 105°C rated parts are functionally equivalent.

Q: Are there physical dimension differences between substitute parts?

A: Most substitutes maintain the original 0.709" diameter and 1.476" height. Chemi-Con alternatives (ESMG201ELL221MMP1S, EKMG201ELL221MMP1S, EKMQ251ELL221MMP1S, ESMQ251ELL221MMP1S) have a height of 1.457", representing a 0.019" reduction. This minor difference remains within standard PCB clearance tolerances for through-hole components and does not affect mechanical compatibility.

Q: Which substitute offers the best long-term availability?

A: Parts with "Active" product status offer the best long-term availability. ESMG201ELL221MMP1S (Chemi-Con), UAQ2D221MHD (Nichicon), 250PK220MEFC18X35.5 (Rubycon), 250PX220MEFC18X35.5 (Rubycon), B43821A2227M000 (EPCOS - TDK Electronics), EKMQ251ELL221MMP1S (Chemi-Con), and ESMQ251ELL221MMP1S (Chemi-Con) all carry active status. Parts marked "Not For New Designs" or "Discontinued at DiGi Electronics" have limited future availability.

Q: Does RoHS compliance affect electrical performance?

A: RoHS compliance relates to material composition and environmental standards, not electrical performance. All ROHS3 compliant substitutes maintain identical electrical specifications to the original UVR2D221MHA. The upgrade from RoHS non-compliant to ROHS3 compliant status reflects improved environmental and regulatory alignment without affecting circuit functionality.

Q: Can I substitute based on ripple current specifications?

A: Ripple current capacity varies among substitutes. The original UVR2D221MHA specifies 810 mA @ 120 Hz and 1.296 A @ 10 kHz. Direct equivalents (UVR2D221MHD, ESMG201ELL221MMP1S, B43821A2227M000) maintain similar ripple current ratings. Upgraded alternatives with extended temperature ranges (UAQ2D221MHD, EKMG201ELL221MMP1S) show reduced ripple current capacity due to thermal design optimization. For applications with specific ripple current requirements, verify the substitute part's ripple current specification against circuit demands.
