Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UPM1H331MHD6TN 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 and operating temperature range of -55°C to 105°C must be maintained
• Mechanical Compatibility: Lead spacing (7.50 mm), case diameter (16.00 mm), and through-hole radial mounting configuration must be identical
• Package Format: Radial, Can package type with Cut Tape (CT) packaging

The UPJ1H331MHD6TN meets all these substitution criteria, providing functional equivalence for the UPM1H331MHD6TN in applications where the electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The UPJ1H331MHD6TN serves as a direct functional equivalent to the UPM1H331MHD6TN for applications requiring 330 µF, 50 V aluminum electrolytic capacitors with radial through-hole configuration.

Compliance Considerations: Both parts are ROHS3 compliant. The UPM1H331MHD6TN carries AEC-Q200 automotive certification, while the UPJ1H331MHD6TN is rated for general purpose applications. Selection between these parts depends on whether automotive-grade qualification is required for the target application.

Physical Compatibility: The UPJ1H331MHD6TN has a maximum seated height of 16.50 mm compared to 17.00 mm for the UPM1H331MHD6TN. This 0.50 mm difference must be verified against PCB layout constraints and clearance requirements in the target assembly.

Electrical Performance: Impedance values differ slightly (60 mOhms vs. 78 mOhms), which may affect high-frequency ripple current performance in noise-sensitive circuits. All other electrical parameters, including ripple current ratings at 120 Hz and 10 kHz, are identical.

Frequently Asked Questions (FAQ)

Q: Can the UPJ1H331MHD6TN replace the UPM1H331MHD6TN in automotive applications?

A: The UPJ1H331MHD6TN matches all critical electrical and mechanical parameters. However, the UPM1H331MHD6TN carries AEC-Q200 automotive certification while the UPJ1H331MHD6TN is rated for general purpose use. Substitution in automotive applications requires verification that AEC-Q200 qualification is not a mandatory requirement for your specific system.

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

A: The UPM1H331MHD6TN has 60 mOhms impedance while the UPJ1H331MHD6TN has 78 mOhms. This 18 mOhm difference may impact performance in high-frequency filtering applications. For circuits sensitive to impedance characteristics, measure or simulate the effect before substitution.

Q: Will the UPJ1H331MHD6TN fit in the same PCB footprint?

A: Both parts have identical lead spacing (7.50 mm) and case diameter (16.00 mm). The UPJ1H331MHD6TN is 0.50 mm shorter in seated height (16.50 mm vs. 17.00 mm). Verify clearance above the component to ensure no interference with overlying components or enclosure elements.

Q: Are both parts available in the same packaging format?

A: Yes, both the UPM1H331MHD6TN and UPJ1H331MHD6TN are supplied in Cut Tape (CT) packaging and are through-hole radial configuration components.

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

A: This designation indicates the UPM1H331MHD6TN is in mature or end-of-life phase. New designs should consider alternative current-generation capacitors. For legacy system support and repair, the UPJ1H331MHD6TN provides functional continuity.
