Substitute Part Grouping Explanation

Substitution for the UVR2E220MHA is determined by strict adherence to the following electrical and mechanical parameters:

Core Substitution Criteria:

Capacitance: 22 µF (exact match required)
Voltage Rating: 250 V minimum (higher voltage ratings are acceptable as upgrades)
Tolerance: ±20% (matching tolerance)
Polarization: Polar (required)
Package: Radial, Can (physical form factor)
Lead Spacing: 0.197" (5.00 mm) (exact match required for PCB compatibility)
Case Diameter: 0.492" (12.50 mm) (exact match required)
Mounting Type: Through Hole (required)

Parametric Equivalent: Parts matching all core criteria with identical electrical performance at rated conditions.

Upgrade Substitutes: Parts exceeding the original specifications in voltage rating, operating temperature range, or lifetime rating while maintaining identical physical dimensions and lead spacing.

Engineering Selection Recommendations

Parametric Equivalent (Direct Replacement):

UVR2E220MHD1AA is the parametric equivalent to UVR2E220MHA, maintaining identical electrical specifications and physical dimensions. This part remains within the UVR series and is currently in active production status.

Nichicon Upgrade Substitutes (Same Manufacturer):

UBT2E220MHD8 provides extended operating temperature range (-40°C to 125°C) and ROHS3 compliance while maintaining 250 V rating and identical physical form factor. Suitable for applications requiring automotive-grade reliability.

UAS2G220MHD and UCS2G220MHD offer increased voltage rating (400 V) with ROHS3 compliance. UCS2G220MHD provides extended lifetime (10000 Hrs @ 105°C) compared to the original 2000-hour rating.

UCS2V220MHD and UCY2V220MHD3 provide 350 V rating with extended lifetime ratings (10000 and 12000 hours respectively) and ROHS3 compliance.

Rubycon Upgrade Substitutes (Alternative Manufacturer):

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a substitute?

A: Yes. A capacitor rated at 350 V or 400 V can replace the 250 V UVR2E220MHA in the same circuit. Higher voltage ratings provide additional safety margin and do not affect circuit operation when the applied voltage remains at or below 250 V.

Q: Are all substitute parts physically compatible with the original PCB layout?

A: Yes, all listed substitutes maintain the same lead spacing (5.00 mm), case diameter (12.50 mm), and height (22.00 mm or 21.50 mm for UCS series). Through-hole mounting configuration is identical across all parts.

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

A: Both manufacturers provide equivalent electrical performance and identical physical dimensions. Selection between manufacturers depends on supply chain availability, procurement preferences, and application-specific requirements. All listed Rubycon parts are ROHS3 compliant.

Q: Does the UVR2E220MHD1AA have the same performance as the obsolete UVR2E220MHA?

A: Yes. UVR2E220MHD1AA is the parametric equivalent, maintaining identical capacitance (22 µF), voltage rating (250 V), tolerance (±20%), lifetime rating (2000 Hrs @ 85°C), and operating temperature range (-40°C to 85°C).

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

A: UCS2G220MHD and UCY2V220MHD3 provide the highest lifetime ratings (10000 and 12000 hours respectively at 105°C) with ROHS3 compliance and extended operating temperature ranges.

Q: Can I use a 22 µF capacitor with different tolerance?

A: No. Substitutes must maintain ±20% tolerance to ensure circuit performance specifications are met. Tolerance directly affects capacitance accuracy and circuit behavior.

Q: Are all substitutes RoHS compliant?

A: The original UVR2E220MHA is RoHS non-compliant. All active substitute parts listed are ROHS3 compliant, meeting current environmental and regulatory requirements.
