Substitute Part Grouping Explanation

Substitute parts for the UVR2E220MHD1TO are categorized based on the following substitution criteria:

Direct Substitutes (Parametric Equivalents): Parts with identical capacitance (22 µF), voltage rating (250 V), tolerance (±20%), lead spacing (5.00 mm), case diameter (12.50 mm), and through-hole radial mounting. Packaging format differences (Cut Tape vs. Tape & Box) do not affect electrical compatibility.

Voltage-Upgraded Substitutes: Parts maintaining 22 µF capacitance and ±20% tolerance with higher voltage ratings (315 V, 350 V, 400 V). These provide enhanced voltage margin and are mechanically compatible with identical lead spacing and case dimensions.

Performance-Enhanced Substitutes: Parts with improved lifetime ratings, extended operating temperature ranges, or higher ripple current capacity while maintaining core electrical parameters and mechanical compatibility.

Cross-Manufacturer Alternatives: Equivalent parts from manufacturers other than Nichicon (Rubycon) meeting identical electrical specifications and mechanical form factors.

Engineering Selection Recommendations

Primary Recommendation for Direct Replacement: UVR2E220MHD1TD (Nichicon, Active Status)

This part provides exact electrical and mechanical equivalence to the UVR2E220MHD1TO with identical capacitance, voltage rating, tolerance, temperature range, and physical dimensions. The only difference is packaging format (Tape & Box vs. Cut Tape), which does not affect circuit performance. Active product status ensures long-term availability and supply chain stability.

Recommended Upgrade Path: UBT2E220MHD8TO (Nichicon, Active Status)

This automotive-grade alternative maintains the 22 µF, 250 V specification with identical mechanical compatibility. It extends the operating temperature range to 125°C and provides 2000-hour lifetime at this elevated temperature, offering improved thermal performance for applications requiring higher temperature margins. ROHS3 and REACH compliance are maintained.

Higher Voltage Alternatives for Enhanced Margin: UCY2V220MHD3TO or UCS2V220MHD1TO (Nichicon, Active Status)

Both parts provide 350 V rating with 22 µF capacitance, delivering 40% voltage headroom above the original 250 V specification. UCY2V220MHD3TO offers 12000-hour lifetime at 105°C, while UCS2V220MHD1TO provides 10000-hour lifetime at 105°C. Both extend operating temperature to 105°C. Mechanical compatibility is maintained with identical lead spacing and case diameter; height is reduced by 0.5 mm (21.50 mm vs. 22.00 mm), which is acceptable for through-hole applications.

Cross-Manufacturer Alternative: 350PX22MEFCG412.5X20 (Rubycon, Active Status)

This Rubycon part matches the 22 µF, 350 V specification with identical mechanical dimensions and lead spacing. It provides 2000-hour lifetime at 105°C operating temperature range. ROHS3 compliance is maintained. This option provides supply diversification from a different manufacturer.

Maximum Voltage Upgrade: UCS2G220MHD1TO or 400PX22MEFCG412.5X20 (Active Status)

Both parts provide 400 V rating with 22 µF capacitance, delivering 60% voltage headroom. UCS2G220MHD1TO (Nichicon) offers 10000-hour lifetime at 105°C with extended temperature range. 400PX22MEFCG412.5X20 (Rubycon) provides 2000-hour lifetime at 105°C.

Frequently Asked Questions (FAQ)

Q: Can UVR2E220MHD1TD be used as a direct replacement for UVR2E220MHD1TO?

A: Yes. Both parts are electrically and mechanically identical with 22 µF capacitance, 250 V rating, ±20% tolerance, -40°C to 85°C operating range, and identical physical dimensions (5.00 mm lead spacing, 12.50 mm diameter, 22.00 mm height). The only difference is packaging format (Tape & Box vs. Cut Tape), which does not affect circuit performance. UVR2E220MHD1TD has Active product status, ensuring continued availability.

Q: What is the advantage of upgrading to UBT2E220MHD8TO?

A: UBT2E220MHD8TO maintains the same 22 µF, 250 V electrical specification and mechanical form factor but extends the maximum operating temperature to 125°C with 2000-hour lifetime at this temperature. This provides superior thermal performance for applications operating in elevated ambient conditions. It is automotive-grade and carries Active product status.

Q: Are higher voltage-rated substitutes (350 V, 400 V) compatible with circuits designed for 250 V?

A: Yes. Higher voltage-rated capacitors are electrically compatible with lower voltage circuit requirements. A 350 V or 400 V capacitor can be used in a 250 V circuit without performance degradation. The higher voltage rating provides additional safety margin and does not affect capacitance value or tolerance. Mechanical compatibility is maintained with identical lead spacing and case diameter.

Q: What is the difference between Nichicon and Rubycon alternatives?

A: Both manufacturers produce aluminum electrolytic capacitors meeting the same electrical specifications (22 µF, ±20% tolerance) and mechanical form factors (5.00 mm lead spacing, 12.50 mm diameter). Rubycon alternatives such as 350PX22MEFCG412.5X20 and 400PX22MEFCG412.5X20 provide supply chain diversification. Selection between manufacturers depends on procurement strategy, inventory availability, and established supplier relationships.

Q: Why do some substitute parts have reduced height (21.50 mm vs. 22.00 mm)?

A: Height reduction occurs in higher-performance series (UCY, UCS) due to improved internal construction and materials that achieve longer lifetime ratings (10000-12000 hours at 105°C) in a more compact form factor. The 0.5 mm reduction is negligible for through-hole applications and does not affect PCB layout or mechanical clearance in standard designs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, ensuring compatibility with environmental and regulatory requirements. REACH status varies by part; refer to individual part specifications for REACH compliance details.

Q: What ripple current capacity should be considered when selecting a substitute?

A: The original UVR2E220MHD1TO handles 190 mA at 120 Hz and 304 mA at 10 kHz. Higher-performance alternatives such as UCY2V220MHD3TO and UCS2V220MHD1TO provide increased ripple current capacity (325 mA @ 120 Hz, 650 mA @ 100 kHz), beneficial for applications with demanding AC current requirements. Rubycon alternatives provide comparable ripple current handling. Selection should match circuit ripple current specifications.

Q: Can UVR2E220MHD1TO be used in new designs?

A: No. UVR2E220MHD1TO is classified as Not For New Designs. For new designs, select from Active status alternatives such as UVR2E220MHD1TD, UBT2E220MHD8TO, UCY2V220MHD3TO, UCS2V220MHD1TO, UCS2G220MHD1TO, or cross-manufacturer options from Rubycon.
