Nichicon USV0J330MFD Equivalent & Substitute Parts

Part Overview

The Nichicon USV0J330MFD is a 33 µF, 6.3 V aluminum electrolytic capacitor in radial through-hole configuration with a 5000-hour lifetime rating at 105°C. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. Substitute parts are selected based on matching capacitance, tolerance, and core electrical characteristics while accommodating variations in voltage rating, package type, and performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the USV0J330MFD is based on the following core parameters:

• Capacitance: All substitutes maintain 33 µF
• Tolerance: All substitutes maintain ±20%
• Voltage Rating: Substitutes may exceed the 6.3 V rating; higher voltage ratings are acceptable for direct replacement
• Mounting Type & Package: Substitutes are grouped by through-hole or surface-mount configurations
• Lifetime & Temperature: Substitutes must support the operating temperature range of -40°C ~ 105°C
• Compliance: All substitutes maintain ROHS3 compliance and REACH unaffected status

Three substitute parts are identified:

1. UUL0J330MCL1GS – Same voltage rating (6.3 V), surface-mount variant, active product status
2. RNS1C330MDS1 – Higher voltage rating (16 V), polymer type, through-hole, active product status
3. UHE1V330MDD – Higher voltage rating (35 V), through-hole, obsolete product status

Parameter Comparison

Engineering Selection Recommendations

For Through-Hole Applications with Matching Voltage: UUL0J330MCL1GS is not suitable due to surface-mount configuration. For through-hole replacement at 6.3 V, no direct equivalent exists among the listed substitutes.

For Through-Hole Applications with Higher Voltage Tolerance: RNS1C330MDS1 (16 V, polymer type, active status) and UHE1V330MDD (35 V, standard type, obsolete status) are both viable. RNS1C330MDS1 is preferred due to active product status and extended operating temperature range (-55°C ~ 105°C). Note that RNS1C330MDS1 has a reduced lifetime of 2000 hours at 105°C compared to the original 5000 hours.

For Surface-Mount Applications: UUL0J330MCL1GS provides an active, surface-mount alternative with identical voltage and lifetime specifications. Physical dimensions differ; verify PCB land pattern compatibility.

Compliance Considerations: All substitutes maintain ROHS3 compliance and REACH unaffected status, matching the original part's regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can UUL0J330MCL1GS replace USV0J330MFD in a through-hole design? A: No. UUL0J330MCL1GS is a surface-mount component (SMD package), while USV0J330MFD is through-hole. Physical mounting incompatibility prevents direct substitution without PCB redesign.

Q: Is RNS1C330MDS1 a direct replacement for USV0J330MFD? A: RNS1C330MDS1 matches capacitance, tolerance, and through-hole mounting. However, it differs in voltage rating (16 V vs. 6.3 V), lifetime (2000 Hrs vs. 5000 Hrs @ 105°C), and type (polymer vs. standard aluminum). Higher voltage rating is acceptable for direct replacement in circuits designed for 6.3 V operation. Verify application requirements for lifetime specifications.

Q: Why does UHE1V330MDD have a taller profile than the original part? A: UHE1V330MDD has a height of 0.433" (11.00mm) compared to USV0J330MFD at 0.315" (8.00mm). This is due to the higher voltage rating (35 V). Verify PCB clearance before substitution.

Q: Are all substitutes ROHS3 compliant? A: Yes. All three substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory compliance of the original USV0J330MFD.

Q: What is the key difference between RNS1C330MDS1 and UHE1V330MDD? A: RNS1C330MDS1 is an aluminum-polymer capacitor with 16 V rating and active product status. UHE1V330MDD is a standard aluminum electrolytic capacitor with 35 V rating and obsolete product status. RNS1C330MDS1 is preferred for new designs due to active availability.
