UVR2D330MHD1TO Equivalent & Substitute Parts

Part Overview

The UVR2D330MHD1TO is a 33 µF, 200 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 This component is classified as "Not For New Designs," indicating it has been superseded in the product lifecycle. The part is rated for 2000 hours at 85°C and is suitable for general-purpose applications requiring through-hole mounting with 5.00 mm lead spacing.

Equivalent and substitute parts are necessary to support existing designs, provide extended component availability, or upgrade to improved performance characteristics such as higher voltage ratings, extended lifetime ratings, or enhanced ripple current handling.

Substitute Part Grouping Explanation

Substitution of the UVR2D330MHD1TO is determined by the following criteria:

Mandatory Compatibility Parameters:

Capacitance: 33 µF (exact match required)
Tolerance: ±20% (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)

Allowable Variation Parameters:

Voltage - Rated: Equal to or greater than 200 V
Operating Temperature Range: Equal to or greater than -40°C ~ 85°C
Lifetime @ Temperature: Equal to or greater than 2000 Hrs @ 85°C
Physical dimensions (diameter and height): Within acceptable PCB layout tolerances
Ripple Current ratings: Equal to or greater than specified values

Substitute parts are grouped into two categories:

Direct Equivalents: Parts with identical or superior electrical and thermal characteristics that maintain the same series designation or represent direct functional replacements.

Upgraded Alternatives: Parts with enhanced performance specifications (higher voltage ratings, extended lifetime, improved ripple current handling) that provide superior reliability while maintaining mechanical and electrical compatibility.

Engineering Selection Recommendations

For Direct Replacement (Same Series, Active Status): UCS2E330MHD1TO is the recommended upgrade path. This part maintains Nichicon manufacturing consistency, achieves Active product status, and provides 10000 hours lifetime at 105°C compared to the original 2000 hours at 85°C. The 250 V rating exceeds the 200 V requirement, and ripple current performance is doubled across both frequency ranges.

For Enhanced Performance (Higher Voltage Rating): UCY2V330MHD1TO or EKXJ351ETE330MK20S provide 350 V ratings with 12000 hours (Nichicon UCY series) or 10000 hours (Chemi-Con KXJ series) lifetime at 105°C. Both parts exceed the original specifications and are classified as Active products. The Chemi-Con EKXJ351ETE330MK20S carries AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability.

For Equivalent Voltage Substitution (Same Series, Legacy Status): UVR2E330MHD1TO provides a 250 V variant within the same UVR series. This part maintains identical thermal and ripple current characteristics to the original but is also classified as "Not For New Designs." This option is suitable only for legacy design support where series consistency is required.

For Intermediate Performance (250 V, Active Status): UCY2E330MHD3TO delivers 250 V rating with 12000 hours lifetime at 105°C and Active product status. This represents a balanced upgrade offering improved reliability without the higher voltage rating of the 350 V alternatives.

All substitute parts maintain identical mechanical compatibility: 5.00 mm lead spacing, 12.50 mm diameter, and radial through-hole mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can UVR2E330MHD1TO be used as a direct replacement for UVR2D330MHD1TO?

A: Yes, with voltage margin consideration. UVR2E330MHD1TO is electrically compatible with identical capacitance (33 µF), tolerance (±20%), lead spacing (5.00 mm), and mounting type. The 250 V rating exceeds the 200 V requirement. However, both parts carry "Not For New Designs" status. For new designs or long-term support, UCS2E330MHD1TO is preferred.

Q: What is the primary advantage of UCS2E330MHD1TO over the original part?

A: UCS2E330MHD1TO provides five times longer lifetime (10000 hours at 105°C versus 2000 hours at 85°C), doubled ripple current capacity, extended operating temperature range to 105°C, and Active product status ensuring continued availability and support.

Q: Are there physical dimension differences between substitute parts?

A: Yes. The original UVR2D330MHD1TO has a maximum seated height of 22.00 mm. Substitute parts UCS2E330MHD1TO, UCY2E330MHD3TO, UCY2V330MHD1TO, and EKXJ351ETE330MK20S have a maximum seated height of 21.50 mm. This 0.50 mm reduction is within standard PCB layout tolerances. Lead spacing remains constant at 5.00 mm across all parts.

Q: Can EKXJ351ETE330MK20S be used in non-automotive applications?

A: Yes. EKXJ351ETE330MK20S meets ROHS3 compliance and carries AEC-Q200 automotive qualification. Automotive-qualified components exceed standard industrial reliability requirements and are suitable for general-purpose applications. The higher qualification level does not restrict use in non-automotive designs.

Q: What is the difference between UCY2E330MHD3TO and UCY2V330MHD1TO?

A: Both are Nichicon UCY series parts with 12000 hours lifetime at 105°C and Active status. UCY2E330MHD3TO is rated 250 V with 400 mA ripple current at 120 Hz. UCY2V330MHD1TO is rated 350 V with 380 mA ripple current at 120 Hz. Selection depends on circuit voltage requirements: use 250 V for lower voltage applications, 350 V for higher voltage margins.

Q: Is RoHS compliance consistent across all substitute parts?

A: Yes. All parts listed—UVR2D330MHD1TO, UVR2E330MHD1TO, UCS2E330MHD1TO, UCY2E330MHD3TO, UCY2V330MHD1TO, and EKXJ351ETE330MK20S—are ROHS3 compliant.
