Substitute Part Grouping Explanation

Substitution for the UVR2F221MRD is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 220 µF (exact match required)
• Rated voltage: 315 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting type: Through Hole (exact match required)
• Package configuration: Radial, Can (exact match required)
• Operating temperature range: -40°C ~ 85°C (exact match required)
• Lifetime rating: 2000 Hrs @ 85°C (exact match required)

The substitute part UVR2F221MRD6 meets all electrical equivalence criteria. Physical dimensions and ripple current ratings differ within acceptable manufacturing tolerances for the same series and electrical specification class.

Parameter Comparison

Engineering Selection Recommendations

Both UVR2F221MRD and UVR2F221MRD6 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Both components carry EAR99 classification and share identical HTSUS coding. The electrical specifications—capacitance, voltage rating, tolerance, operating temperature range, and lifetime rating—are identical between the two parts.

Selection between these parts is determined by physical space constraints and PCB layout requirements. The UVR2F221MRD6 features a larger diameter (25.00mm vs 22.00mm) and greater lead spacing (12.50mm vs 10.00mm), but reduced height (32.00mm vs 52.00mm). Ripple current ratings are lower in the UVR2F221MRD6 variant; circuit design must confirm that application ripple current requirements do not exceed 770 mA @ 120 Hz or 1.232 A @ 10 kHz.

Frequently Asked Questions (FAQ)

Q: Can UVR2F221MRD6 be used as a direct replacement for UVR2F221MRD?

A: UVR2F221MRD6 is electrically equivalent across all specified parameters: capacitance, voltage rating, tolerance, temperature range, and lifetime. Physical dimensions differ; PCB layout and available mounting space must accommodate the larger diameter and different lead spacing of the UVR2F221MRD6.

Q: What are the key differences between these two parts?

A: The primary differences are physical dimensions and ripple current ratings. UVR2F221MRD6 has a larger diameter (25.00mm) and wider lead spacing (12.50mm) but shorter height (32.00mm). Ripple current capacity is lower: 770 mA @ 120 Hz versus 850 mA, and 1.232 A @ 10 kHz versus 1.36 A.

Q: Are both parts compliant with current environmental standards?

A: Both UVR2F221MRD and UVR2F221MRD6 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component procurement.

Q: What determines whether I can substitute one part for the other?

A: Electrical equivalence is confirmed across all specified parameters. Substitution feasibility depends on physical space availability on the PCB and whether application ripple current requirements fall within the lower ratings of the UVR2F221MRD6 variant.

Q: Why is the original UVR2F221MRD marked as obsolete?

A: Product status indicates obsolescence in the manufacturer's product line. UVR2F221MRD6 remains available as the current equivalent offering within the same UVR series, maintaining identical electrical specifications.
