UEP0J331MPD Equivalent & Substitute Parts

Part Overview

The Nichicon UEP0J331MPD is a 330 µF, 6.3 V aluminum electrolytic capacitor in radial, can package configuration. This component is classified as Not For New Designs, indicating it has reached end-of-life status. The part operates across a temperature range of -55°C to 105°C with a rated lifetime of 1000 hours at 105°C, making it suitable for general-purpose applications requiring stable capacitance and ripple current handling.

Finding equivalent or substitute parts becomes necessary when the original UEP0J331MPD reaches inventory depletion or when design updates require components with active product status and extended availability.

Substitute Part Grouping Explanation

Substitution of the UEP0J331MPD is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Substitution:

• Capacitance value: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: Minimum 6.3 V (equal or higher voltage rating is acceptable)
• Operating temperature range: -55°C to 105°C (must encompass or match)
• Lifetime specification: 1000 Hrs @ 105°C (must meet or exceed)
• Polarization: Bi-Polar (exact match required)
• Mounting type: Through Hole (exact match required)
• Package configuration: Radial, Can (exact match required)
• Lead spacing: 0.138" (4.60 mm) (exact match required)
• Physical dimensions: 0.315" Dia (8.00 mm), Height 0.512" (13.00 mm) (exact match required)

The Rubycon 10NXA330MEFC8X11.5 qualifies as a substitute because it maintains identical capacitance, tolerance, polarization, mounting type, package style, lead spacing, and physical dimensions. The voltage rating of 10 V exceeds the minimum 6.3 V requirement, providing additional design margin. Both parts share identical operating temperature range and equivalent lifetime specifications.

Engineering Selection Recommendations

The Rubycon 10NXA330MEFC8X11.5 is the qualified substitute for the Nichicon UEP0J331MPD based on the following engineering criteria:

Product Status: The substitute part carries Active product status, ensuring continued availability and manufacturing support. The original UEP0J331MPD is classified as Not For New Designs, making the transition to an active alternative necessary for long-term supply chain stability.

Compliance and Certifications: Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for equivalent applications. Both parts carry identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications.

Electrical Compatibility: The substitute part's 10 V voltage rating exceeds the 6.3 V requirement of the original design, providing additional voltage margin without compromising circuit functionality. Capacitance, tolerance, and temperature specifications remain identical, ensuring direct functional equivalence in general-purpose applications.

Physical and Mechanical Compatibility: Identical lead spacing, package dimensions, and mounting configuration ensure direct board-level compatibility without PCB redesign or layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the Rubycon 10NXA330MEFC8X11.5 be used as a direct replacement for the Nichicon UEP0J331MPD?

A: Yes. Both parts share identical capacitance (330 µF), tolerance (±20%), polarization (Bi-Polar), lead spacing (0.138" / 4.60 mm), physical dimensions (0.315" Dia / 8.00 mm, Height 0.512" / 13.00 mm), and mounting configuration (Through Hole, Radial Can). The substitute's 10 V voltage rating exceeds the original 6.3 V specification, providing additional design margin. Direct board-level substitution is possible without PCB modifications.

Q: What is the significance of the voltage rating difference between the two parts?

A: The substitute part's 10 V rating is higher than the original 6.3 V specification. In circuit applications, a higher voltage-rated capacitor can safely operate at lower voltages without performance degradation. This provides additional voltage margin and may improve reliability in applications subject to voltage transients or supply variations.

Q: Are the ripple current specifications identical between the two parts?

A: No. The Nichicon UEP0J331MPD specifies 185 mA @ 120 Hz and 277.5 mA @ 10 kHz. The Rubycon 10NXA330MEFC8X11.5 specifies 147 mA @ 120 Hz and 176.4 mA @ 10 kHz. For applications requiring specific ripple current handling, verify that the substitute part's ripple current ratings meet circuit requirements.

Q: Do both parts have identical temperature and lifetime specifications?

A: Yes. Both parts operate across -55°C to 105°C and maintain 1000 hours lifetime at 105°C, ensuring equivalent thermal performance and expected service life in general-purpose applications.

Q: What is the inventory status of each part?

A: The Nichicon UEP0J331MPD has 1298 pieces in stock. The Rubycon 10NXA330MEFC8X11.5 has 803 pieces in stock. Both are listed as new original inventory.

Q: Are there any compliance or regulatory differences between the two parts?

A: No. Both parts are ROHS3 compliant, REACH Unaffected, and carry identical ECCN and HTSUS classifications, satisfying equivalent regulatory requirements for component selection and procurement.
