Substitute Part Grouping Explanation

Substitution of the UBX1A331MPL1TD is determined by strict equivalence across the following parameters:

• Capacitance value: 330 µF (exact match required)
• Rated voltage: 10 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Lifetime specification: 1000 Hrs @ 150°C (exact match required)
• Operating temperature range: -55°C ~ 150°C (exact match required)
• Ripple current ratings: 150 mA @ 120 Hz and 300 mA @ 100 kHz (exact match required)
• Package type: Radial, Can (exact match required)
• Physical dimensions and lead spacing (exact match required)
• Compliance certifications: ROHS3 Compliant (exact match required)

The UBX1A331MPD1TD meets all these criteria and qualifies as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The UBX1A331MPD1TD is a direct parametric equivalent to the obsolete UBX1A331MPL1TD. Both components are manufactured by Nichicon within the UBX series and share identical electrical and mechanical specifications. The substitute part maintains full compliance with ROHS3 requirements and automotive application standards.

The primary distinction is product status: the main part is obsolete while the substitute remains in active production. This makes the UBX1A331MPD1TD the appropriate selection for new procurement and system support where the UBX1A331MPL1TD is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the UBX1A331MPD1TD be used as a direct replacement for the UBX1A331MPL1TD?

A: Yes. Both parts are identical in capacitance (330 µF), rated voltage (10 V), tolerance (±20%), lifetime specification (1000 Hrs @ 150°C), operating temperature range (-55°C ~ 150°C), ripple current ratings, physical dimensions, and package type. They are pin-compatible and functionally equivalent.

Q: What is the difference between these two part numbers?

A: The UBX1A331MPL1TD is obsolete, while the UBX1A331MPD1TD is in active production. The electrical and mechanical specifications are identical. The difference in the part number suffix reflects manufacturing or internal Nichicon designation changes.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ROHS3 compliance status and are suitable for automotive applications with the same environmental and regulatory requirements.

Q: Will the substitute part fit the same PCB footprint?

A: Yes. The lead spacing (0.197" / 5.00 mm), diameter (0.394" / 10.00 mm), and maximum seated height (0.689" / 17.50 mm) are identical, ensuring mechanical compatibility with existing board layouts.

Q: What are the key parameters that must match for substitution?

A: Capacitance value, rated voltage, tolerance, polarization, lifetime specification, operating temperature range, ripple current ratings, package type, and physical dimensions must all match exactly for direct substitution.
