UVZ1E221MPD Equivalent & Substitute Parts

Part Overview

The UVZ1E221MPD is a 220 µF, 25 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is classified as Not For New Designs, indicating it has been superseded in the product portfolio. The part operates across a temperature range of -55°C to 105°C with a rated lifetime of 1000 hours at 105°C, making it suitable for general-purpose applications requiring stable capacitance and ripple current handling.

Identifying equivalent and substitute parts is necessary due to the product's obsolescence status and potential supply constraints. Suitable alternatives must maintain the same capacitance value (220 µF), voltage rating (25 V or higher), and mechanical compatibility while offering improved reliability characteristics or active product status.

Engineering Selection Recommendations

For Direct PCB Footprint Compatibility (No Layout Modification Required):

Select UKA1E221MPD or UPS1E221MPD when the original UVZ1E221MPD footprint must be preserved. Both parts maintain identical lead spacing (0.138"), case diameter (0.315"), and maximum height (0.512" or less). UKA1E221MPD provides doubled lifetime (2000 Hrs vs. 1000 Hrs) with no mechanical penalty. UPS1E221MPD offers reduced height (0.453") for space-constrained applications while maintaining 2000 Hrs lifetime.

For Active Product Status:

UVY1V221MPD is the only substitute with Active product status, ensuring long-term availability and supply continuity. This part provides 35 V voltage rating (suitable for 25 V applications with margin) and maintains identical mechanical dimensions to the original part.

For Extended Lifetime Requirements:

UPJ1E221MPD and UPM1E221MPD deliver 3000 Hrs @ 105°C lifetime. UPM1E221MPD includes AEC-Q200 automotive qualification. Both require PCB layout accommodation for increased height (0.630" and 0.650" respectively). UPJ1E221MPD6 and UPM1E221MPD6 extend lifetime to 5000 Hrs but require footprint redesign due to modified lead spacing (0.197") and increased case diameter (0.394").

For Compliance and Certification:

All listed substitutes maintain ROHS3 compliance. UPM series parts carry AEC-Q200 automotive qualification, suitable for automotive-grade applications. UKA1V221MPD and UVY1V221MPD provide 35 V rating, offering voltage margin for circuits designed for 25 V operation.

For Space-Constrained Designs:

UPS1E221MPD and UPW1E221MPD offer reduced height (0.453") while maintaining standard lead spacing and case diameter, enabling direct substitution in height-limited applications.

Frequently Asked Questions (FAQ)

Q: Can UVY1V221MPD replace UVZ1E221MPD in a 25 V circuit?

A: Yes. UVY1V221MPD is rated for 35 V, which exceeds the 25 V requirement. The higher voltage rating provides operational margin and does not degrade performance in 25 V applications. All other electrical parameters (220 µF capacitance, ±20% tolerance, -55°C to 105°C operating range) are identical. Mechanical dimensions match exactly, enabling direct PCB substitution.

Q: What is the difference between UKA1E221MPD and UPS1E221MPD?

A: Both parts share 220 µF capacitance, 25 V rating, and 2000 Hrs @ 105°C lifetime. UKA1E221MPD maintains the original height of 0.512", while UPS1E221MPD is shorter at 0.453". Lead spacing and case diameter are identical for both. Selection depends on available PCB clearance; UPS1E221MPD is preferred for space-constrained designs.

Q: Are UPJ1E221MPD6 and UPM1E221MPD6 direct replacements?

A: No. These parts require PCB footprint redesign. Lead spacing increases from 0.138" to 0.197", and case diameter increases from 0.315" to 0.394". However, they deliver 5000 Hrs @ 105°C lifetime, the highest available. UPM1E221MPD6 includes AEC-Q200 automotive qualification. Use these parts only when PCB layout modification is feasible.

Q: Why is UVY1E221MED listed as Obsolete?

A: UVY1E221MED has been discontinued and is not recommended for new designs. Although it shares the same electrical specifications as UVZ1E221MPD, its smaller mechanical dimensions (0.098" lead spacing, 0.248" case diameter) make it unsuitable as a direct replacement. Existing inventory may be available, but UVY1V221MPD (Active status) is the preferred alternative from the UVY series.

Q: Can I use a 35 V rated capacitor in place of a 25 V rated capacitor?

A: Yes. A higher voltage rating does not compromise performance in lower voltage applications. UKA1V221MPD and UVY1V221MPD are both rated for 35 V and function correctly in 25 V circuits. The higher rating provides voltage margin and may improve reliability. Verify that PCB layout accommodates the physical dimensions.

Q: What is the impact of increased ripple current capability?

A: Higher ripple current ratings indicate improved thermal performance and lower impedance. UPJ1E221MPD (455 mA @ 120 Hz) and UPM1E221MPD (455 mA @ 120 Hz) handle greater ripple current than the original UVZ1E221MPD (240 mA @ 120 Hz). This improvement reduces heat generation and extends operational life in high-ripple applications. Selection should be based on actual circuit ripple current requirements.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the environmental certification of the original UVZ1E221MPD. No compliance degradation occurs with any listed alternative.
