Substitute Part Grouping Explanation

Substitution of the UPW2D220MPD is determined by strict equivalence in the following core parameters:

Capacitance: 22 µF (exact match required)
Voltage Rating: 200 V (minimum; higher ratings are acceptable)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Case Diameter: 0.394" (10.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)

Parts are grouped into three categories based on their relationship to the main part:

MFR Recommended Substitutes: Direct replacements from the same manufacturer (Nichicon) with identical electrical specifications and improved performance metrics.

Similar Substitutes: Parts meeting all core electrical and mechanical parameters but from alternative manufacturers or with different performance characteristics (lifetime, ripple current ratings).

Direct Equivalents: Cross-manufacturer parts with identical specifications from established suppliers.

Upgrade Options: Parts with higher voltage ratings or extended lifetime specifications that provide enhanced design margin.

Engineering Selection Recommendations

Primary Recommendation: UCY2D220MPD

The UCY2D220MPD is the manufacturer-recommended direct replacement for the obsolete UPW2D220MPD. Both parts share identical capacitance, voltage rating, tolerance, and mechanical footprint (lead spacing and case diameter). The UCY2D220MPD offers significant performance improvements: extended lifetime of 12000 hours at 105°C compared to 5000 hours, increased ripple current handling (450 mA @ 100 kHz versus 224 mA @ 10 kHz), and a reduced height of 0.689" versus 0.787". The part is active in production and ROHS3 compliant. This substitution requires no design modifications.

Alternative for Cost-Sensitive Applications: MAL214232229E3 or MAL214252229E3

The Vishay Beyschlag MAL214 series parts (142 RHS) provide active, ROHS3-compliant alternatives with identical electrical specifications. Both variants maintain 22 µF capacitance, 200 V rating, and ±20% tolerance. These parts feature a reduced height of 0.689" and ripple current rating of 213 mA @ 10 kHz. Lifetime specification is 2500 hours at 105°C. The primary distinction between MAL214232229E3 and MAL214252229E3 is packaging (Tape & Box versus Bulk). These parts are suitable for general-purpose applications where the reduced lifetime is acceptable.

Upgrade Option: EKXG251ELL220MJ20S

The Chemi-Con EKXG251ELL220MJ20S provides an enhanced specification upgrade with 250 V rating (versus 200 V), 8000-hour lifetime at 105°C, and superior ripple current capability (500 mA @ 100 kHz). Mechanical compatibility is maintained with identical lead spacing and case diameter. This part is recommended for applications requiring extended operational margin or higher voltage transient immunity. The 250 V rating is backward-compatible with 200 V circuit designs.

Not Recommended for New Designs: UVZ2D220MPD, UAQ2D220MPD

The UVZ2D220MPD is designated "Not For New Designs" and the UAQ2D220MPD, while active, offers reduced lifetime specifications (2000 hours at 105°C). These parts should be avoided in new designs despite meeting core electrical and mechanical parameters.

Mechanical Constraint: UPM2D220MHD

The UPM2D220MHD is obsolete and features a larger case diameter (0.492" versus 0.394") and greater height (1.063" versus 0.787"), making it unsuitable for direct substitution in existing PCB layouts. This part is not recommended.

Frequently Asked Questions (FAQ)

Q: Can UCY2D220MPD be used as a direct drop-in replacement for UPW2D220MPD?

A: Yes. The UCY2D220MPD maintains identical capacitance (22 µF), voltage rating (200 V), tolerance (±20%), lead spacing (5.00 mm), and case diameter (10.00 mm). The reduced height (0.689" versus 0.787") is a physical improvement that does not affect electrical compatibility. No circuit modifications are required.

Q: What is the difference between MAL214232229E3 and MAL214252229E3?

A: Both parts are electrically and mechanically identical. The primary difference is packaging: MAL214232229E3 is supplied in Tape & Box format, while MAL214252229E3 is supplied in Bulk packaging. Selection depends on procurement and assembly requirements.

Q: Why is EKXG251ELL220MJ20S listed as an upgrade option?

A: The EKXG251ELL220MJ20S provides a higher voltage rating (250 V versus 200 V) and extended lifetime (8000 hours versus 5000 hours). These specifications offer increased design margin and reliability. The part maintains mechanical compatibility and is suitable for applications where enhanced performance is beneficial.

Q: Can parts with different heights be used interchangeably?

A: Height differences affect PCB layout and component clearance. The UCY2D220MPD (0.689" height) is shorter than the UPW2D220MPD (0.787" height), which is advantageous for space-constrained designs. The UAQ2D220MPD and UVZ2D220MPD are taller (0.866" and 0.827" respectively) and may require layout verification. The UPM2D220MHD is significantly larger and incompatible with existing layouts.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, maintaining regulatory alignment with the original UPW2D220MPD.

Q: What is the significance of product status (Active, Obsolete, Not For New Designs)?

A: Active parts are in current production with guaranteed long-term availability. Obsolete parts are no longer manufactured and should not be specified in new designs. "Not For New Designs" indicates the part is available but not recommended for future applications. For new designs, select only Active parts: UCY2D220MPD, MAL214232229E3, MAL214252229E3, EKXG251ELL220MJ20S, or SEK220M200ST.

Q: How do ripple current ratings affect part selection?

A: Ripple current rating indicates the maximum AC current the capacitor can handle at specified frequency without exceeding temperature limits. Higher ripple current capability (UCY2D220MPD at 450 mA @ 100 kHz) provides better performance in high-frequency switching applications. Lower ratings (UAQ2D220MPD and UVZ2D220MPD at 192 mA @ 10 kHz) are suitable for lower-frequency or lower-current applications.
