Key Parameters

Substitute Part Grouping Explanation

Substitution of the UBX1C331MPL1TD is determined by the following critical parameters:

• Capacitance Value: 330 µF (exact match required)
• Tolerance: ±20% (must match or be tighter)
• Package Configuration: Radial, Can with Through Hole mounting
• Lead Spacing: 0.197" (5.00 mm) (mechanical compatibility)
• Operating Temperature Range: -55°C ~ 150°C (minimum requirement)
• Lifetime Rating: 1000 Hrs @ 150°C (thermal endurance)
• Polarization: Polar (functional requirement)
• Application Category: Automotive (compliance and reliability standards)

The MAL216051331E3 qualifies as a substitute based on matching capacitance, tolerance, package type, lead spacing, operating temperature range, and lifetime specification. The higher voltage rating (50 V vs. 16 V) provides additional design margin and does not prevent substitution in circuits designed for 16 V operation.

Parameter Comparison

Engineering Selection Recommendations

The MAL216051331E3 is suitable for direct substitution of the UBX1C331MPL1TD based on the following factors:

• Both components meet identical capacitance, tolerance, and thermal lifetime specifications
• Lead spacing and package dimensions are compatible with existing PCB layouts
• Operating temperature range and polarization requirements are matched
• Both components carry ROHS3 compliance and automotive-grade certifications
• The MAL216051331E3 maintains active product status, ensuring long-term availability and supply chain continuity
• The higher voltage rating of the MAL216051331E3 (50 V) provides additional safety margin in 16 V circuit applications without performance degradation

Frequently Asked Questions (FAQ)

Q: Can the MAL216051331E3 be used as a direct replacement for the UBX1C331MPL1TD?

A: Yes. Both components share identical capacitance (330 µF), tolerance (±20%), lead spacing (5.00 mm), operating temperature range (-55°C ~ 150°C), and thermal lifetime (1000 Hrs @ 150°C). The radial, can-style package and through-hole mounting are mechanially compatible.

Q: Does the higher voltage rating of the MAL216051331E3 (50 V vs. 16 V) affect circuit operation?

A: No. A capacitor with a higher voltage rating can be used in circuits designed for lower voltages. The 50 V rating provides additional design margin and does not alter the capacitive behavior at 16 V operation.

Q: Are there physical dimension differences between these parts?

A: The MAL216051331E3 has a slightly larger diameter (0.492" vs. 0.394") and height (0.866" vs. 0.846"), but lead spacing remains identical at 0.197" (5.00 mm). PCB layout compatibility depends on available board space around the component footprint.

Q: What is the significance of the product status difference?

A: The UBX1C331MPL1TD is obsolete, meaning Nichicon no longer manufactures or supports this component. The MAL216051331E3 is active, ensuring continued availability, technical support, and supply chain reliability for new designs and production runs.

Q: Do both components meet automotive compliance requirements?

A: Yes. Both the UBX1C331MPL1TD and MAL216051331E3 are rated for automotive applications and carry ROHS3 compliance certification, meeting industry standards for automotive-grade electronic components.
