Engineering Selection Recommendations

UHW2A221MHD1TO (Nichicon): This substitute offers extended lifetime (10000 Hrs @ 105°C) and elevated operating temperature range (-40°C ~ 105°C) compared to the original UVR2A221MHD1TO. Ripple current capacity is significantly higher across both low and high frequency ranges. Product status remains Not For New Designs. Selection is appropriate for applications requiring enhanced thermal performance and extended operational life within the same mechanical footprint.

UKW2A221MHD1TO (Nichicon): This substitute maintains identical electrical specifications and lifetime rating to the UVR2A221MHD1TO with equivalent operating temperature range. The primary distinction is application classification as Audio rather than General Purpose. Mechanical compatibility is complete. Product status is Not For New Designs. Selection is appropriate for direct replacement in audio circuit applications.

ECA-2AHG221B (Panasonic Electronic Components): This substitute is the only option with Active product status, ensuring continued availability and manufacturing support. It carries AEC-Q200 automotive qualification and extends the operating temperature range to -55°C ~ 105°C. Lifetime rating is 2000 Hrs @ 105°C. Ripple current specifications are lower than the original part. Selection is appropriate for new designs, automotive applications, and situations where long-term component availability is critical.

Frequently Asked Questions (FAQ)

Q: Can UHW2A221MHD1TO be used as a direct replacement for UVR2A221MHD1TO?

A: Yes. Both parts share identical capacitance (220 µF), voltage rating (100 V), tolerance (±20%), and mechanical dimensions (lead spacing, case diameter, height). The UHW2A221MHD1TO provides enhanced performance with higher ripple current capacity and extended lifetime rating.

Q: What is the difference between UKW2A221MHD1TO and UVR2A221MHD1TO?

A: Both parts are electrically and mechanically identical. The UKW2A221MHD1TO is designated for audio applications, while the UVR2A221MHD1TO is classified for general purpose use. Substitution is direct.

Q: Why should ECA-2AHG221B be considered despite lower ripple current ratings?

A: The ECA-2AHG221B is the only substitute with Active product status, ensuring long-term availability. It carries AEC-Q200 automotive qualification and supports an extended operating temperature range (-55°C ~ 105°C). Selection depends on whether component longevity and automotive compliance outweigh ripple current requirements in the target application.

Q: Are all substitutes mechanically compatible with the original UVR2A221MHD1TO?

A: Yes. All substitute parts maintain identical lead spacing (0.197" / 5.00 mm), case diameter (0.492" / 12.50 mm), and height (1.063" / 27.00 mm). Through-hole mounting compatibility is complete across all options.

Q: What compliance certifications apply to these substitutes?

A: All parts are ROHS3 compliant and REACH unaffected. The ECA-2AHG221B additionally carries AEC-Q200 automotive qualification. No other ratings are specified for the Nichicon alternatives.
