UVK2C220MPD Equivalent & Substitute Parts

Part Overview

The UVK2C220MPD is a 22 µF, 160 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 This component is classified as Not For New Designs, indicating it has been superseded in Nichicon's product line. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 2000 hours at 85°C, making it suitable for general-purpose applications requiring stable capacitance and moderate ripple current handling.

Identifying equivalent and substitute parts is necessary due to the product's obsolescence status and potential supply constraints. Equivalent alternatives maintain the same electrical specifications while offering improved availability, extended operational lifetime, or enhanced thermal performance from active manufacturers.

Engineering Selection Recommendations

Direct Mechanical and Electrical Equivalents (Preferred for Direct Replacement)

160PK22MEFC10X12.5 (Rubycon) and ESMQ161ELL220MJC5S (Chemi-Con) are direct equivalents to UVK2C220MPD. Both maintain identical capacitance, voltage rating, tolerance, and lifetime specifications (2000 Hrs @ 85°C). Both manufacturers are Active status, ensuring continued supply and support. These parts are suitable for applications where the original thermal and ripple current specifications are sufficient.

Enhanced Performance Substitutes (Recommended for New Designs)

160LLE22MEFC10X12.5 (Rubycon) and EKXF161ELL220MJC5S (Chemi-Con) provide extended operational lifetime (15000 Hrs @ 105°C) while maintaining mechanical compatibility. These parts support higher operating temperatures (-40°C to 105°C) and are classified as Active products. Selection of these parts is appropriate when extended service life or elevated temperature operation is required.

160LEX22MEFC10X12.5 (Rubycon) offers 5000 Hrs @ 125°C lifetime with extended temperature range to 125°C, providing intermediate performance enhancement between standard and premium options.

Alternative Consideration

160PX22MEFC10X12.5 (Rubycon) provides 2000 Hrs @ 105°C operation with extended temperature capability. This part is suitable when moderate thermal performance improvement is needed without requiring the extended lifetime of LLE or KXF series.

Mechanical Constraint Consideration

ESMG161ELL220MJ20S (Chemi-Con) maintains electrical equivalence but has a maximum height of 0.846" (21.50 mm), significantly taller than the original 0.551" (14.00 mm). This part is suitable only for applications where vertical space constraints do not apply.

UVR2C220MPD (Nichicon) has a maximum height of 0.689" (17.50 mm), exceeding the original specification. This part is suitable only where increased height is accommodated by board layout.

All substitute parts maintain ROHS3 compliance and are suitable for applications requiring regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can I use 160LLE22MEFC10X12.5 as a direct replacement for UVK2C220MPD?

A: Yes. 160LLE22MEFC10X12.5 maintains all critical mechanical parameters: 22 µF capacitance, 160 V rating, ±20% tolerance, 0.197" lead spacing, 0.394" case diameter, and Through Hole radial mounting. The maximum height of 0.571" (14.50 mm) is within acceptable tolerance of the original 0.551" (14.00 mm). The part provides enhanced performance with 15000 Hrs @ 105°C lifetime and extended operating temperature range.

Q: What is the difference between 160PK22MEFC10X12.5 and 160PX22MEFC10X12.5?

A: Both parts are manufactured by Rubycon with identical mechanical specifications. The primary difference is thermal performance: 160PK22MEFC10X12.5 is rated 2000 Hrs @ 85°C with operating range -40°C to 85°C, while 160PX22MEFC10X12.5 is rated 2000 Hrs @ 105°C with operating range -40°C to 105°C. Selection depends on the application's thermal environment.

Q: Why is ESMG161ELL220MJ20S listed as a substitute if it is significantly taller?

A: ESMG161ELL220MJ20S maintains all electrical specifications and core mechanical parameters (capacitance, voltage, tolerance, lead spacing, case diameter, mounting type). The increased height of 0.846" (21.50 mm) makes it suitable only for applications where vertical clearance is not constrained. Board layout verification is required before selection.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the original UVK2C220MPD specification.

Q: What is the significance of ripple current ratings in selecting a substitute?

A: Ripple current capacity determines the maximum AC current the capacitor can safely handle without exceeding temperature limits. The original UVK2C220MPD is rated 130 mA @ 120 Hz and 208 mA @ 10 kHz. Substitute parts with equal or higher ripple current ratings are suitable for identical applications. Parts with lower ripple current ratings (such as 160PX22MEFC10X12.5 at 92 mA @ 120 Hz) require verification that application ripple current does not exceed the substitute's specification.

Q: Can I use parts with higher voltage ratings as substitutes?

A: The provided substitute list contains only parts rated 160 V, matching the original specification. Higher voltage-rated parts are not included in this equivalency reference. Voltage derating and circuit design implications require separate engineering analysis.

Q: What does "Product Status: Active" mean for substitute selection?

A: Active status indicates the manufacturer currently produces and supports the part, ensuring continued availability and supply chain stability. The original UVK2C220MPD is classified as "Not For New Designs," making Active-status substitutes preferable for new applications and long-term production requirements.
