Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UPJ1H331MHD6TN is determined by the following critical parameters:

• Electrical Specifications: Capacitance (330 µF), voltage rating (50 V), and tolerance (±20%) must match exactly
• Thermal Performance: Lifetime rating of 5000 hours at 105°C must be maintained
• Mechanical Compatibility: Lead spacing (7.50mm), diameter (16.00mm), and through-hole mounting configuration must align with PCB design
• Polarization: Polar configuration is mandatory
• Compliance: RoHS3 compliance is required

The UPM1H331MHD6TN meets all substitution criteria. While it belongs to a different series (UPM vs. UPJ) and carries automotive-grade certification (AEC-Q200), it maintains identical electrical and mechanical specifications within acceptable tolerances.

Parameter Comparison

Engineering Selection Recommendations

The UPM1H331MHD6TN is a direct functional equivalent to the UPJ1H331MHD6TN. Both components share identical electrical specifications, thermal ratings, and mechanical dimensions suitable for through-hole PCB mounting.

The UPM1H331MHD6TN carries AEC-Q200 automotive-grade certification, indicating enhanced reliability screening and qualification for automotive applications. This certification does not restrict use in non-automotive applications.

Physical height differs by 0.019" (0.50mm), with the UPM variant being slightly taller. PCB layout clearance must be verified to ensure no mechanical interference in confined spaces.

The UPM1H331MHD6TN exhibits lower impedance (60 mOhms vs. 78 mOhms), which provides improved high-frequency performance characteristics.

Both components maintain ROHS3 compliance and identical ripple current ratings across the specified frequency range.

Frequently Asked Questions (FAQ)

Q: Can the UPM1H331MHD6TN replace the UPJ1H331MHD6TN in existing designs?
