UVR1H221MPD Equivalent & Substitute Parts

Part Overview

The UVR1H221MPD is a 220 µF, 50 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as "Not For New Designs," indicating it has been superseded in the product lifecycle. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 2000 hours at 85°C, suitable for general-purpose applications requiring stable capacitance and ripple current handling.

Locating equivalent and substitute parts is necessary due to the product's discontinued status for new designs, potential supply constraints, and the availability of functionally compatible alternatives from active product lines that meet or exceed the original specifications.

Engineering Selection Recommendations

Nichicon Active Alternatives (Recommended for New Designs): URS1H221MPD and UVR1H221MPD1AA are Nichicon products with Active product status. Both maintain identical electrical specifications to the UVR1H221MPD while offering current manufacturing support and supply continuity. URS1H221MPD operates within the same temperature range (-40°C to 85°C) with marginally lower ripple current (420 mA vs. 430 mA at 120 Hz). UVR1H221MPD1AA provides direct electrical equivalence with full ripple current specification (430 mA at 120 Hz).

Enhanced Thermal Performance Alternatives: UKA1H221MPD (Nichicon) and 227CKE050M (Cornell Dubilier) extend the operating temperature range to -55°C to 105°C with 2000-hour lifetime at 105°C, providing superior thermal margin for applications requiring extended temperature operation. UKA1H221MPD is a Nichicon product with Audio application focus. 227CKE050M is an Active product from Cornell Dubilier with documented ESR specification (754 mOhm @ 120 Hz) and Bypass/Decoupling application classification.

Alternative Manufacturer Options: 50PX220MEFC10X12.5 (Rubycon, Active) and B41821A6227M000 (EPCOS - TDK Electronics, Active) provide cross-manufacturer substitution with identical electrical parameters. 50PX220MEFC10X12.5 offers extended temperature range (-55°C to 105°C). B41821A6227M000 maintains standard temperature range with documented ESR (900 mOhm @ 120 Hz) and slightly reduced height (0.531" vs. 0.551").

Panasonic Options: ECA-1HM221 and ECA-1HM221B (Panasonic, Active) are functionally equivalent with identical electrical specifications. ECA-1HM221B is packaged in Tape & Box format, while ECA-1HM221 is supplied in Bulk packaging. Both feature reduced height (0.531" vs. 0.551") and slightly lower ripple current (400 mA at 120 Hz).

All recommended substitutes maintain ROHS3 compliance and are suitable for direct PCB mounting replacement without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can UVR1H221MPD be directly replaced with URS1H221MPD? A: Yes. URS1H221MPD is a parametric equivalent with identical capacitance (220 µF), voltage rating (50 V), tolerance (±20%), package dimensions, and lead spacing. The primary difference is Active product status versus Not For New Designs. Electrical performance is equivalent within specified ripple current tolerances.

Q: What is the difference between UVR1H221MPD1AA and UVR1H221MPD1CP? A: Both parts are UVR series variants with identical electrical specifications. UVR1H221MPD1AA has Active product status, while UVR1H221MPD1CP is Not For New Designs. For new designs, UVR1H221MPD1AA is the preferred choice due to ongoing manufacturing support.

Q: Why do some substitutes have different heights (0.531" vs. 0.551")? A: B41821A6227M000 (EPCOS - TDK) and ECA-1HM221/ECA-1HM221B (Panasonic) have a maximum seated height of 0.531" compared to the UVR1H221MPD at 0.551". This 0.020" (0.50 mm) difference must be evaluated against PCB clearance requirements. These parts are mechanically compatible for most applications but require verification of vertical space constraints.

Q: Are there temperature range differences between substitutes? A: Yes. UKA1H221MPD, 227CKE050M, and 50PX220MEFC10X12.5 extend the operating range to -55°C to 105°C with 2000-hour lifetime at 105°C, compared to the UVR1H221MPD at -40°C to 85°C with 2000-hour lifetime at 85°C. These extended-range parts are suitable for applications requiring broader thermal operation but are not required for standard -40°C to 85°C applications.

Q: What is the significance of ripple current differences? A: Ripple current specifications indicate the maximum AC current the capacitor can handle at specified frequency without exceeding temperature limits. The UVR1H221MPD is rated at 430 mA @ 120 Hz. Substitutes with lower ripple current ratings (e.g., UKA1H221MPD at 300 mA, 227CKE050M at 350 mA) may require circuit evaluation if ripple current approaches these limits. Parts with equal or higher ripple current (e.g., ECA-1HM221 at 400 mA) are directly compatible.

Q: Can I use ECA-1HM221B (Tape & Box packaging) instead of Bulk packaging? A: Yes, electrically and mechanically. ECA-1HM221B is identical to ECA-1HM221 except for packaging format. Tape & Box packaging is suitable for automated assembly processes, while Bulk packaging is typical for manual or mixed-volume applications. Component performance is identical regardless of packaging format.

Q: Which substitute offers the best long-term supply availability? A: URS1H221MPD and UVR1H221MPD1AA (Nichicon, Active status) offer the most reliable long-term supply continuity. 227CKE050M (Cornell Dubilier, Active), 50PX220MEFC10X12.5 (Rubycon, Active), B41821A6227M000 (EPCOS - TDK, Active), and ECA-1HM221/ECA-1HM221B (Panasonic, Active) are all Active products with established manufacturing support.

Q: Are all substitutes ROHS3 compliant? A: Yes. All listed substitutes maintain ROHS3 compliance, ensuring compatibility with environmental and regulatory requirements equivalent to the original UVR1H221MPD specification.
