Nichicon UBX1E331MHL Equivalent & Substitute Parts

Part Overview

The Nichicon UBX1E331MHL is a 330 µF, 25 V aluminum electrolytic capacitor in radial, can package configuration. This component is designed for through-hole mounting applications requiring long operational life at elevated temperatures, with a rated lifetime of 1000 hours at 150°C. The part is Active status and ROHS3 compliant, making it suitable for automotive applications. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, design flexibility, or application-specific performance needs.

Substitute Part Grouping Explanation

The Vishay Beyschlag/Draloric/BC Components MAL216050331E3 qualifies as a substitute for the Nichicon UBX1E331MHL based on the following alignment of critical parameters:

Electrical Compatibility:

• Identical capacitance: 330 µF
• Identical tolerance: ±20%
• Identical lifetime rating: 1000 Hrs @ 150°C
• Identical operating temperature range: -55°C ~ 150°C
• Identical polarization: Polar

Mechanical Compatibility:

• Identical lead spacing: 0.197" (5.00mm)
• Identical case diameter: 0.492" (12.50mm)
• Equivalent height: 1.043" (26.50mm) vs. 1.063" (27.00mm) — within acceptable through-hole PCB mounting tolerance
• Identical mounting type: Through Hole
• Identical package type: Radial, Can

Regulatory & Compliance:

• Both ROHS3 compliant
• Both rated for automotive applications
• Substitute part carries AEC-Q200 qualification

The substitute part operates at a higher rated voltage (35 V vs. 25 V), which provides additional design margin and does not compromise compatibility in circuits designed for 25 V operation.

Parameter Comparison

Engineering Selection Recommendations

Both the Nichicon UBX1E331MHL and Vishay MAL216050331E3 are Active status components with full ROHS3 compliance. The substitute part carries AEC-Q200 qualification, meeting automotive reliability standards. Selection between these parts should be based on:

• Inventory availability: The Vishay part has higher stock levels (1700 pcs vs. 1062 pcs).
• Voltage margin: The 35 V rated substitute provides 10 V additional headroom over the 25 V design requirement, suitable for applications requiring enhanced voltage stress tolerance.
• Physical fit: The 0.020" (0.50mm) height difference is negligible for standard through-hole PCB layouts and does not affect component placement or clearance.
• Thermal performance: Both parts maintain identical lifetime ratings at 150°C, ensuring equivalent long-term reliability in high-temperature automotive environments.

Frequently Asked Questions (FAQ)

Q: Can the Vishay MAL216050331E3 directly replace the Nichicon UBX1E331MHL?

A: Yes. Both parts share identical capacitance (330 µF), tolerance (±20%), thermal lifetime (1000 Hrs @ 150°C), operating temperature range (-55°C ~ 150°C), lead spacing (5.00mm), case diameter (12.50mm), and mounting type (through-hole radial). The 0.50mm height difference and higher voltage rating (35 V vs. 25 V) do not prevent direct substitution.

Q: Does the higher voltage rating of the substitute part affect circuit operation?

A: No. A capacitor rated for higher voltage than the circuit requires operates normally at lower voltage stress. The 35 V rating of the Vishay part provides additional design margin when used in 25 V circuits without altering electrical performance.

Q: Are there any PCB layout considerations when substituting these parts?

A: The parts are mechanically equivalent for standard through-hole PCB layouts. The 0.50mm height difference (1.043" vs. 1.063") is within typical PCB clearance tolerances and does not require layout modification.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both parts are rated for automotive applications. The Vishay substitute carries AEC-Q200 qualification, meeting automotive reliability standards. Both are ROHS3 compliant.

Q: What is the ripple current capability difference between these parts?

A: The Nichicon part is rated for 300 mA @ 120 Hz and 600 mA @ 100 kHz. The Vishay substitute is rated for 455 mA @ 100 Hz. Selection should be based on the specific ripple current requirements of the application.
