UVP0J331MPD Equivalent & Substitute Parts

Part Overview

The UVP0J331MPD is a 330 µF, 6.3 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as Not For New Designs, indicating it has been superseded in Nichicon's product portfolio. For applications requiring this capacitance and voltage rating, equivalent alternatives from active product lines are available to ensure design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the UVP0J331MPD is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 6.3 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime: 2000 Hrs @ 85°C (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)
• Polarization: Bi-Polar (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Radial, Can (exact match required)

Two Panasonic Electronic Components alternatives meet these criteria: ECE-A0JN331U and ECE-A0JN331UB. Both are from the active SU series and provide identical electrical performance. The distinction between these substitutes is packaging format (Bulk vs. Tape & Box) and lead spacing configuration.

Parameter Comparison

Engineering Selection Recommendations

ECE-A0JN331U is the primary substitute for UVP0J331MPD. Both parts share identical lead spacing (0.138" / 4.60mm), ensuring direct PCB footprint compatibility without layout modification. The Panasonic part is from an active product line with ROHS3 compliance and REACH Unaffected status, providing superior long-term supply chain assurance compared to the Nichicon Not For New Designs classification.

ECE-A0JN331UB is a secondary substitute suitable only when PCB layout accommodates the wider lead spacing of 0.197" (5.00mm). This variant is available in Tape & Box packaging format, which may be preferred for automated assembly processes. The electrical performance and compliance certifications are identical to ECE-A0JN331U.

Both Panasonic alternatives demonstrate equivalent or superior ripple current performance at high frequency (425 mA @ 10 kHz vs. 397.5 mA @ 10 kHz for the original part), with slightly reduced height profiles that may provide PCB layout advantages in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can ECE-A0JN331U be used as a direct replacement for UVP0J331MPD without PCB modification?

A: Yes. ECE-A0JN331U maintains identical lead spacing (0.138" / 4.60mm), capacitance (330 µF), voltage rating (6.3 V), and mounting type (Through Hole Radial). No PCB layout changes are required.

Q: What is the difference between ECE-A0JN331U and ECE-A0JN331UB?

A: The primary difference is lead spacing: ECE-A0JN331U uses 0.138" (4.60mm) spacing, while ECE-A0JN331UB uses 0.197" (5.00mm) spacing. Secondary differences include packaging format (Bulk vs. Tape & Box) and seated height (0.453" vs. 0.492"). Electrical specifications are identical.

Q: Why is the UVP0J331MPD marked as Not For New Designs?

A: This designation indicates the part has been superseded in Nichicon's active product portfolio. For new designs and ongoing production, Panasonic ECE-A0JN331U or ECE-A0JN331UB are recommended to ensure supply continuity and access to manufacturer support.

Q: Are there compliance or regulatory differences between these parts?

A: All three parts are ROHS3 Compliant and carry EAR99 ECCN classification. ECE-A0JN331U and ECE-A0JN331UB are REACH Unaffected, while UVP0J331MPD is REACH Affected. For applications subject to REACH regulations, the Panasonic alternatives provide simplified compliance documentation.

Q: What is the impact of the different ripple current ratings?

A: ECE-A0JN331U and ECE-A0JN331UB both deliver 425 mA @ 10 kHz, exceeding the UVP0J331MPD specification of 397.5 mA @ 10 kHz. This represents improved performance margin in high-frequency ripple current applications. At 120 Hz, the Panasonic parts deliver 250 mA versus 265 mA for the original part, a minor reduction that remains within typical design tolerances.
