Nichicon UVR0J330MDA Equivalent & Substitute Parts

Part Overview

The Nichicon UVR0J330MDA is a 33 µF, 6.3 V aluminum electrolytic capacitor in radial, can package with a rated lifetime of 2000 hours at 85°C. This component is classified as obsolete and operates across a temperature range of -40°C to 85°C, making it suitable for general-purpose applications requiring stable capacitance and ripple current handling at low voltage levels.

Due to its obsolete status, equivalent and substitute parts are necessary for ongoing design support, production continuity, and system maintenance. Substitutes are selected based on matching or exceeding the electrical and mechanical parameters of the original specification.

Engineering Selection Recommendations

Direct Equivalent (Same Voltage Rating):

UVR0J330MDD is the direct equivalent to UVR0J330MDA, maintaining identical electrical specifications (33 µF, 6.3 V, ±20%, 2000 Hrs @ 85°C). The primary difference is RoHS3 compliance status and a marginal increase in seated height (0.492" vs 0.433"). This part is suitable for direct replacement in applications where RoHS compliance is required or preferred.

Upgrade Options (Higher Voltage Ratings with Enhanced Performance):

UPW series parts (UPW1A330MDD at 10 V, UPW1C330MDD at 16 V, UPW1E330MDD at 25 V, UPW1V330MDD at 35 V) provide higher voltage ratings with extended operating temperature range (-55°C to 105°C) and improved thermal performance (2000 Hrs @ 105°C). These are suitable for applications requiring greater voltage margin or enhanced reliability in elevated temperature environments. All UPW parts maintain the original 0.433" seated height and are ROHS3 compliant.

Alternative Options (Different Voltage Ratings for Specific Applications):

UFW and UKW series parts at 35 V and 50 V ratings are suitable for applications requiring higher voltage headroom. UFW1H330MDD and UKW1H330MDD (50 V) provide the highest voltage rating with increased ripple current capability (120 mA @ 120 Hz, 240 mA @ 10 kHz). UHE1V330MDD (35 V) offers extended lifetime (5000 Hrs @ 105°C) for long-life applications requiring superior thermal stability.

All substitute parts maintain through-hole mounting compatibility, radial can package configuration, and 0.079" (2.00 mm) lead spacing. ROHS3 compliance is standard across all substitute options except the original UVR0J330MDA.

Frequently Asked Questions (FAQ)

Q: Can UVR0J330MDD be used as a direct replacement for UVR0J330MDA?

A: Yes. UVR0J330MDD is electrically identical to UVR0J330MDA with matching capacitance (33 µF), voltage rating (6.3 V), tolerance (±20%), and lifetime rating (2000 Hrs @ 85°C). The seated height increases from 0.433" to 0.492", which may require PCB layout verification. UVR0J330MDD is ROHS3 compliant, whereas the original is non-compliant.

Q: What is the difference between UPW and UFW/UKW series substitutes?

A: UPW series parts feature extended operating temperature range (-55°C to 105°C) and thermal performance rated at 105°C, making them suitable for applications requiring enhanced reliability in elevated temperature environments. UFW and UKW series maintain the original -40°C to 85°C operating range but offer higher voltage ratings (35 V and 50 V) with increased ripple current capability for audio and general-purpose applications requiring greater voltage margin.

Q: Are all substitute parts through-hole compatible with the original PCB layout?

A: All substitute parts maintain 0.079" (2.00 mm) lead spacing and 0.197" (5.00 mm) case diameter, ensuring through-hole footprint compatibility. However, seated height varies: UVR0J330MDD, UFW1H330MDD, and UFW1V330MDD are 0.492" (12.50 mm), while UPW series, UKW1V330MDD, UKW1H330MDD, and UHE1V330MDD are 0.433" (11.00 mm). Verify clearance in applications with height-constrained layouts.

Q: Which substitute offers the longest operational lifetime?

A: UHE1V330MDD provides the longest rated lifetime at 5000 hours @ 105°C, compared to 2000 hours @ 85°C for the original UVR0J330MDA. This extended lifetime is achieved through enhanced thermal design and is suitable for applications requiring maximum reliability over extended service periods.

Q: Can a higher voltage-rated substitute be used in a circuit designed for 6.3 V?

A: Yes. Higher voltage-rated capacitors (10 V, 16 V, 25 V, 35 V, 50 V) are electrically compatible in circuits designed for lower voltages. The capacitor will operate well within its voltage rating, providing additional safety margin. However, higher voltage ratings typically result in increased physical size or different thermal characteristics; verify mechanical fit and thermal performance requirements for your specific application.

Q: What is the impact of RoHS compliance on part selection?

A: All substitute parts except the original UVR0J330MDA are ROHS3 compliant. If your application or supply chain requires RoHS compliance, select from the substitute options. RoHS compliance does not affect electrical performance or mechanical compatibility; it reflects manufacturing process and material composition standards.
