Substitute Part Grouping Explanation

Substitution eligibility for the UPJ1J331MHD6TN is determined by the following critical parameters:

Electrical Specifications: Capacitance (330 µF), voltage rating (63 V), and tolerance (±20%) must match exactly
Thermal Performance: Lifetime rating of 5000 hours at 105°C must be maintained
Mechanical Compatibility: Lead spacing (7.50 mm), diameter (18.00 mm), and through-hole mounting must be preserved
Regulatory Compliance: RoHS3 compliance is required

Based on these criteria, the following parts qualify as direct substitutes:

UPJ1J331MHD6 (Nichicon, Bulk packaging) — Identical electrical and mechanical specifications; differs only in packaging format (Bulk vs. Cut Tape).

UPM1J331MHD6TN (Nichicon, Cut Tape packaging) — Meets all critical electrical and mechanical parameters. Includes AEC-Q200 automotive qualification and lower impedance (50 mOhms vs. 78 mOhms). Height tolerance differs slightly (0.669" vs. 0.650" maximum seated height).

Engineering Selection Recommendations

UPJ1J331MHD6 is the primary direct substitute. It maintains identical electrical and mechanical specifications as the UPJ1J331MHD6TN, with the only difference being packaging format (Bulk vs. Cut Tape). Selection of this part is appropriate when packaging requirements permit bulk sourcing.

UPM1J331MHD6TN is a qualified alternative for applications requiring automotive-grade components. This part carries AEC-Q200 certification and features lower impedance (50 mOhms), which may provide performance benefits in ripple-current-sensitive applications. The maximum seated height is 0.019" (0.50 mm) taller than the main part; PCB layout clearance must be verified before substitution. Both parts are manufactured by Nichicon and maintain ROHS3 compliance.

All three parts carry "Not For New Designs" status, indicating they are suitable for legacy system support and production continuity only.

Frequently Asked Questions (FAQ)

Q: Can UPJ1J331MHD6 be used as a direct replacement for UPJ1J331MHD6TN?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging: UPJ1J331MHD6TN is supplied in Cut Tape (CT), while UPJ1J331MHD6 is supplied in Bulk. Functional performance in the circuit is identical.

Q: What is the difference between UPJ1J331MHD6TN and UPM1J331MHD6TN?

A: Both parts share identical capacitance (330 µF), voltage rating (63 V), and thermal specifications (5000 Hrs @ 105°C). The UPM1J331MHD6TN features lower impedance (50 mOhms vs. 78 mOhms) and carries AEC-Q200 automotive qualification. The maximum seated height differs by 0.019" (0.50 mm). Verify PCB clearance before substitution.

Q: Are all three parts RoHS compliant?

A: Yes. UPJ1J331MHD6TN, UPJ1J331MHD6, and UPM1J331MHD6TN are all ROHS3 compliant.

Q: Can I use these parts in new designs?

A: No. All three parts carry "Not For New Designs" status. They are suitable for production support of existing designs and legacy systems only.

Q: Does the impedance difference between UPJ and UPM series affect circuit performance?

A: The UPM1J331MHD6TN has lower impedance (50 mOhms vs. 78 mOhms). In applications sensitive to ripple current or high-frequency noise, lower impedance may provide improved performance. Circuit analysis is required to determine if this difference is beneficial or irrelevant for your specific application.

Q: What is the impact of the 0.019" height difference?

A: The UPM1J331MHD6TN has a maximum seated height of 0.669" compared to 0.650" for the UPJ series. Verify that PCB layout and enclosure clearance accommodate this additional height before substitution.
