Substitute Part Grouping Explanation

Substitution for the UPJ1E331MPD6TD is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 25 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Lead spacing: 0.197" (5.00 mm) (exact match required)
• Package type: Radial, Can (exact match required)
• Mounting type: Through Hole (exact match required)

The UPM1E331MPD6TD meets all these criteria and qualifies as a direct substitute. While the UPM series exhibits improved electrical performance characteristics (lower ESR, higher ripple current ratings) and automotive-grade qualification (AEC-Q200), these enhancements do not disqualify it from substitution in general purpose applications where the UPJ series was originally specified.

Parameter Comparison

Engineering Selection Recommendations

The UPM1E331MPD6TD is a qualified substitute for the UPJ1E331MPD6TD based on electrical and mechanical parameter equivalence. Both components maintain ROHS3 compliance and identical core specifications (capacitance, voltage, tolerance, temperature range, and package dimensions).

The UPM series offers improved performance metrics (lower ESR and higher ripple current ratings) and carries AEC-Q200 automotive qualification, which provides additional reliability assurance. The height difference of 0.019" (0.50 mm) between the two variants is within typical PCB layout tolerances for through-hole components.

Selection between these parts should be based on application requirements, inventory availability, and compliance mandates specific to the end-use environment.

Frequently Asked Questions (FAQ)

Q: Can the UPM1E331MPD6TD replace the UPJ1E331MPD6TD in existing designs?

A: Yes. Both components share identical electrical specifications (330 µF, 25 V, ±20% tolerance) and mechanical compatibility (lead spacing, package type, mounting method). The UPM variant exhibits superior performance characteristics and does not introduce incompatibility.

Q: What is the significance of the height difference between these parts?

A: The UPM1E331MPD6TD has a maximum seated height of 0.669" (17.00 mm) compared to 0.650" (16.50 mm) for the UPJ1E331MPD6TD. This 0.019" (0.50 mm) difference is within standard PCB clearance tolerances for through-hole radial capacitors and does not typically require design modification.

Q: Why does the UPM series have lower ESR and higher ripple current ratings?

A: These are inherent performance characteristics of the UPM series design. Lower ESR and higher ripple current capacity represent improved electrical performance but do not affect functional substitutability in applications where the original UPJ specification was met.

Q: Are there compliance differences between these parts?

A: Both components are ROHS3 compliant. The UPM1E331MPD6TD carries AEC-Q200 automotive qualification, which the UPJ1E331MPD6TD does not. This additional certification does not restrict use in general purpose applications.

Q: What does "Not For New Designs" status mean for substitution?

A: This status indicates the original part is obsolete or being phased out. Identifying and qualifying substitute parts is necessary for production continuity. The UPM1E331MPD6TD serves this purpose while maintaining full electrical and mechanical compatibility.
