Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UPM1J331MHD6TN is determined by the following critical parameters:

• Electrical Parameters: Capacitance (330 µF), voltage rating (63 V), and tolerance (±20%) must match exactly
• Thermal Performance: Lifetime rating of 5000 Hrs @ 105°C and operating temperature range of -55°C ~ 105°C must be maintained
• Mechanical Compatibility: Lead spacing (7.50mm), case diameter (18.00mm), and through-hole mounting configuration must be identical
• Environmental Compliance: RoHS3 compliance is required; REACH status may vary based on application requirements

The UPJ1J331MHD6TN meets all critical substitution criteria. Both parts share identical electrical specifications, thermal ratings, mechanical dimensions, and RoHS compliance status. The primary distinction lies in application classification (automotive vs. general purpose) and impedance characteristics, which do not affect functional interchangeability in circuits designed for the specified electrical parameters.

Engineering Selection Recommendations

Both the UPM1J331MHD6TN and UPJ1J331MHD6TN are designated "Not For New Designs," reflecting their legacy classification within Nichicon's product portfolio. Selection between these parts should be based on application requirements and compliance mandates:

For Automotive Applications: The UPM1J331MHD6TN carries AEC-Q200 certification, qualifying it for automotive-grade applications. This part is the primary choice when automotive compliance is a design requirement.

For General Purpose Applications: The UPJ1J331MHD6TN is classified for general purpose use and provides equivalent electrical and thermal performance without automotive-specific certification overhead.

Compliance Considerations: Both parts are ROHS3 compliant. The UPM1J331MHD6TN is REACH Affected, while the UPJ1J331MHD6TN is REACH Unaffected. Application location and regulatory jurisdiction determine which compliance status is appropriate.

Mechanical Fit: The UPJ1J331MHD6TN has a maximum seated height of 0.650" (16.50mm) compared to 0.669" (17.00mm) for the UPM1J331MHD6TN. This 0.019" difference is negligible for standard PCB layouts but should be verified in space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can the UPJ1J331MHD6TN directly replace the UPM1J331MHD6TN in automotive applications?

A: Electrical and thermal substitution is possible due to matching capacitance, voltage, tolerance, and lifetime ratings. However, the UPJ1J331MHD6TN lacks AEC-Q200 automotive certification. Substitution in automotive designs requires engineering review and approval based on specific application requirements and quality standards.

Q: What is the significance of the impedance difference (50 mOhms vs. 78 mOhms)?

A: Impedance values reflect internal resistance characteristics. The provided specifications do not establish impedance as a substitution criterion. Both parts meet the electrical performance requirements defined by capacitance, voltage, and tolerance parameters.

Q: Are the mechanical dimensions compatible for PCB mounting?

A: Yes. Both parts share identical lead spacing (7.50mm) and case diameter (18.00mm). The seated height difference of 0.019" is within standard PCB clearance tolerances for radial capacitor mounting. Verify clearance in designs with height constraints.

Q: What is the difference between REACH Affected and REACH Unaffected status?

A: REACH Affected indicates the part contains substances subject to REACH regulation compliance. REACH Unaffected indicates no REACH-regulated substances are present. Selection depends on end-market regulatory requirements and supply chain compliance mandates.

Q: Why are both parts marked "Not For New Designs"?

A: This designation indicates both the UPM1J331MHD6TN and UPJ1J331MHD6TN are legacy components. Nichicon recommends evaluating current-generation alternatives for new product development. These parts remain available for existing designs and maintenance applications.
