UVR1C330MDA Equivalent & Substitute Parts

Part Overview

The UVR1C330MDA is a 33 µF, 16 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is classified as obsolete, with a rated lifetime of 2000 hours at 85°C. Due to its obsolete status, equivalent and substitute parts with improved specifications, extended operational lifetimes, or enhanced compliance certifications are available to maintain design continuity and ensure long-term component availability.

Substitute Part Grouping Explanation

Substitution of the UVR1C330MDA is determined by the following critical parameters:

Capacitance: Must remain 33 µF (±20% tolerance acceptable)
Voltage Rating: Must be equal to or greater than 16 V
Package Type: Must be Radial, Can configuration
Lead Spacing: Must be 0.079" (2.00mm)
Size / Dimension: Must be 0.197" Dia (5.00mm)
Height - Seated (Max): Must not exceed 0.433" (11.00mm) for direct mechanical compatibility
Mounting Type: Must be Through Hole
Polarization: Must be Polar

Substitute parts are grouped into two categories:

Category A - Direct Mechanical Replacements (Height ≤ 0.433"): UKW1H330MDD, UKW1V330MDD, UPW1C330MDD, UPW1E330MDD, UPW1V330MDD, 336SAK035M. These maintain identical or compatible physical dimensions and can be used as direct board-level substitutes.

Category B - Higher Voltage / Extended Lifetime (Height > 0.433"): UFW1H330MDD, UFW1V330MDD, UHE1V330MDD, EEU-EB1V330S. These offer improved electrical performance or extended operational lifetime but require verification of available board space due to increased height.

Engineering Selection Recommendations

For Direct Board-Level Replacement (No Layout Modification Required):

Select UPW1C330MDD if the original 16 V rating is required. This part maintains identical physical dimensions (0.433" height) while providing ROHS3 compliance and extended operational temperature range (-55°C ~ 105°C) with 2000 hours lifetime at 105°C.

Select UKW1V330MDD or UKW1H330MDD if voltage derating is acceptable. Both provide ROHS3 compliance and identical physical dimensions. UKW1V330MDD offers 35 V rating; UKW1H330MDD offers 50 V rating.

Select 336SAK035M (Cornell Dubilier / Illinois Capacitor) as an active product alternative. This part is currently in active production status, ensuring long-term availability. It provides ROHS3 compliance, 35 V rating, and slightly reduced height (0.413"), making it suitable for space-constrained applications.

For Extended Operational Lifetime:

Select UHE1V330MDD for applications requiring extended lifetime at elevated temperatures. This part provides 5000 hours at 105°C (versus 2000 hours at 85°C for the original), maintains identical physical dimensions, and offers ROHS3 compliance with expanded operating temperature range (-40°C ~ 105°C).

Select EEU-EB1V330S (Panasonic Electronic Components) as an active product with extended lifetime. This part is currently in active production, provides 5000 hours at 105°C, ROHS3 compliance, and 35 V rating. Height is 0.472", requiring verification of available board space.

For Higher Voltage Derating:

Select UPW1V330MDD for applications requiring higher voltage margin. This part provides 35 V rating with identical physical dimensions, ROHS3 compliance, and extended operational temperature range (-55°C ~ 105°C) with 2000 hours lifetime at 105°C.

Frequently Asked Questions (FAQ)

Q: Can UVR1C330MDA be replaced with a higher voltage-rated capacitor?

A: Yes. Capacitors rated at higher voltages (35 V, 50 V) are electrically compatible as direct substitutes in circuits designed for 16 V operation. The higher voltage rating provides additional safety margin and does not affect circuit functionality. Physical dimensions and lead spacing must remain compatible with the PCB layout.

Q: What is the difference between parts with 0.433" height and those with 0.492" height?

A: Parts with 0.433" height (UKW series, UPW series, UHE1V330MDD) are direct mechanical replacements requiring no PCB modification. Parts with 0.492" height (UFW series) require verification that available board clearance accommodates the increased height. Parts with 0.413" height (336SAK035M) fit in space-constrained applications.

Q: Why should I select an active product status part over an obsolete part?

A: Active product status parts (336SAK035M, EEU-EB1V330S) are currently manufactured and have guaranteed long-term availability. Obsolete parts may become unavailable as manufacturer inventory depletes. For new designs or long-term production requirements, active status parts ensure supply chain continuity.

Q: What does ROHS3 compliance mean for this capacitor?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, hexavalent chromium, and specific brominated flame retardants. The original UVR1C330MDA is RoHS non-compliant; all substitute parts listed are ROHS3 compliant, making them suitable for applications with environmental or regulatory requirements.

Q: Can I use EEU-EB1V330S (Panasonic) as a direct replacement for UVR1C330MDA?

A: EEU-EB1V330S is electrically and functionally compatible. However, its height (0.472") exceeds the original (0.433"), requiring verification of available board clearance. Lead spacing (0.079" / 2.00mm) and diameter (0.197" / 5.00mm) are identical, ensuring footprint compatibility on the PCB.

Q: What is the advantage of UHE1V330MDD over UPW1V330MDD?

A: Both parts provide 33 µF, 35 V, identical physical dimensions, and ROHS3 compliance. UHE1V330MDD offers 5000 hours lifetime at 105°C with operating range -40°C ~ 105°C. UPW1V330MDD offers 2000 hours lifetime at 105°C with extended operating range -55°C ~ 105°C. Selection depends on whether extended high-temperature lifetime or extended low-temperature operation is required.

Q: Are all substitute parts through-hole mounted?

A: Yes. All substitute parts listed are through-hole mounted with 0.079" (2.00mm) lead spacing, maintaining compatibility with existing PCB designs. No surface-mount alternatives are included in this substitution list.
