Substitute Part Grouping Explanation

Substitution eligibility for the UVR1J331MPD1AA is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 330 µF (exact match required)
• Voltage Rating: 63 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime Specification: 2000 Hrs @ 85°C (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Polarization: Polar (exact match required)
• Lead Spacing: 0.197" (5.00mm) (exact match required)
• Physical Dimensions: 0.394" Dia × 0.866" Height (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Radial, Can (exact match required)

The identified substitute parts meet all mandatory electrical and mechanical parameters. Variations in ripple current ratings and product status do not affect functional substitutability within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

UVR1J331MPD (Nichicon): This part is electrically and mechanically identical to the primary part number but carries a "Not For New Designs" status. Selection of this substitute is appropriate only for legacy system maintenance, repair operations, or when existing inventory must be utilized. New design implementations should prioritize active-status alternatives.

ECA-1JM331 (Panasonic): This part maintains full electrical and mechanical equivalence with active product status. The ECA-1JM331 is ROHS3 compliant and carries REACH unaffected certification. This substitute is suitable for new designs, production continuity, and applications where multi-source component qualification is required. The Panasonic M-A series provides equivalent performance within the specified parameter envelope.

Both substitutes are functionally interchangeable based on the provided electrical and mechanical parameters. Selection between them should be based on supply chain availability, design phase requirements, and compliance documentation needs.

Frequently Asked Questions (FAQ)

Q: Can UVR1J331MPD1AA be replaced with UVR1J331MPD in production assemblies?

A: Yes. Both parts are manufactured by Nichicon and share identical electrical and mechanical specifications. However, UVR1J331MPD carries "Not For New Designs" status, making it suitable only for repair and maintenance of existing systems.

Q: Is ECA-1JM331 a direct substitute for UVR1J331MPD1AA?

A: Yes. The ECA-1JM331 meets all critical parameters: 330 µF capacitance, 63 V rating, ±20% tolerance, 2000 Hrs @ 85°C lifetime, identical physical dimensions, and through-hole radial can package. It is manufactured by Panasonic and carries active product status.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by exact equivalence in capacitance value (330 µF), voltage rating (63 V), tolerance (±20%), lifetime specification (2000 Hrs @ 85°C), operating temperature range (-40°C ~ 85°C), lead spacing (5.00mm), physical dimensions (10.00mm diameter × 22.00mm height), and package type (radial, can, through-hole).

Q: Are there differences in ripple current ratings between these parts?

A: Yes. Ripple current specifications vary: UVR1J331MPD1AA provides 1.065 A @ 10 kHz, UVR1J331MPD provides 816.5 mA @ 10 kHz, and ECA-1JM331 provides 935 mA @ 10 kHz. These variations do not affect substitutability within the specified parameter set for general-purpose applications.

Q: What compliance certifications apply to these substitutes?

A: UVR1J331MPD and ECA-1JM331 are both ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification. Moisture sensitivity level is not applicable for these radial can packages.
