Substitute Part Grouping Explanation

Substitution of the UBC1V331MNS1MS is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 35 V (minimum, equal or higher acceptable)
• Tolerance: ±20% (matching tolerance class)
• Polarization: Polar (required for electrolytic type)
• Operating temperature range: -55°C ~ 150°C (minimum coverage required)
• Ripple current capability: 650 mA @ 100 kHz (minimum performance required)

Mechanical Equivalence Criteria:

• Package type: Radial, Can - SMD (exact match required)
• Physical diameter: 12.50 mm (exact match required)
• Physical height: 14.50 mm maximum (equal or lower required for PCB fit)
• Mounting type: Surface Mount (exact match required)
• MSL rating: 1 (Unlimited) (equal or better required)

Compliance Criteria:

• RoHS3 compliance (required for automotive applications)
• REACH unaffected status (required for regulatory compliance)

The substitute part MAL216099002E3 meets all electrical and mechanical equivalence criteria and maintains full regulatory compliance.

Engineering Selection Recommendations

The MAL216099002E3 manufactured by Vishay Beyschlag/Draloric/BC Components is a direct functional equivalent to the UBC1V331MNS1MS. Selection of this substitute is supported by the following engineering factors:

Product Status Alignment: The original part carries "Not For New Designs" status, while the substitute maintains "Active" product status, making it suitable for ongoing production and new design implementations.

Compliance and Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in automotive applications. The substitute carries AEC-Q200 qualification, providing enhanced automotive reliability assurance.

Performance Characteristics: The substitute meets or exceeds all specified electrical parameters. The lifetime rating of 1250 hours at 150°C exceeds the original specification of 1000 hours, providing improved thermal endurance. Physical height of 14.00 mm is lower than the original 14.50 mm maximum, ensuring PCB layout compatibility without modification.

Electrical Compatibility: Capacitance, voltage rating, tolerance, ripple current capability, and operating temperature range are identical between the two parts, ensuring direct functional substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can MAL216099002E3 be used as a direct replacement for UBC1V331MNS1MS without PCB modification?

A: Yes. Both parts share identical electrical specifications (330 µF, 35 V, ±20% tolerance) and identical physical diameter (12.50 mm). The substitute has a lower maximum height (14.00 mm vs. 14.50 mm), which is compatible with existing PCB layouts designed for the original part.

Q: What is the significance of the "Not For New Designs" status on the original part?

A: This status indicates that Nichicon has discontinued active development and promotion of the UBC1V331MNS1MS. For new product designs and ongoing production, the active substitute MAL216099002E3 is the appropriate selection.

Q: Are there any thermal performance differences between these parts?

A: The substitute demonstrates superior thermal performance with a lifetime rating of 1250 hours at 150°C compared to the original 1000 hours at 150°C. Both parts operate across the identical temperature range of -55°C to 150°C.

Q: Does the substitute meet automotive qualification requirements?

A: Yes. The MAL216099002E3 carries AEC-Q200 qualification, which is the automotive industry standard for discrete semiconductors and passive components. Both parts are RoHS3 compliant and REACH unaffected, meeting automotive regulatory requirements.

Q: Are the surface mount land sizes compatible?

A: The original part specifies 13.60 mm × 13.60 mm land size, while the substitute specifies 12.90 mm × 12.90 mm. The substitute's smaller land size is compatible with PCB layouts designed for the original part, as it occupies less board space.

Q: What is the impedance specification of the substitute?

A: The substitute MAL216099002E3 has an impedance of 80 mOhms. This specification was not provided for the original part but represents the electrical resistance characteristic of the substitute at operating frequency.
