Substitute Part Grouping Explanation

Substitute parts for the UUE1V331MNS1MS are identified based on strict electrical and mechanical compatibility criteria. The primary substitution logic is based on the following allowed parameters:

Critical Matching Parameters:

• Capacitance value: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: Radial, Can - SMD (exact match required)
• Physical dimensions: 0.630" Dia (16.00mm), Height 0.689" (17.50mm) (exact match required)
• Surface mount land size: 0.673" L x 0.673" W (17.10mm x 17.10mm) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Polarization: Polar (exact match required)
• Series: UUE (exact match required)
• Manufacturer: Nichicon (exact match required)

Allowable Variation Parameters:

• Voltage rating: May be equal to or higher than the main part (35 V minimum)
• Lifetime @ temperature: May be equal to or higher than the main part (5000 Hrs @ 125°C minimum)
• Ripple current specifications: May vary within the same package class

The UUE1H331MNS1MS qualifies as a substitute because it maintains all critical matching parameters while offering an upgraded voltage rating of 50 V, providing enhanced electrical margin for the same physical footprint and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the UUE1V331MNS1MS and UUE1H331MNS1MS are active production parts manufactured by Nichicon with full RoHS3 compliance and unlimited moisture sensitivity rating. Both components are qualified for automotive applications and maintain identical mechanical compatibility with the same surface mount footprint and land pattern.

The UUE1H331MNS1MS offers a higher voltage rating of 50 V compared to the 35 V rating of the main part, while maintaining all other electrical and mechanical specifications. This higher voltage rating provides additional electrical margin within the same physical package. Both parts share identical capacitance, tolerance, operating temperature range, lifetime rating, and mounting characteristics.

Selection between these parts should be based on the specific voltage requirements of the application circuit. The 50 V rated substitute is suitable for applications where the original 35 V specification can accommodate the higher voltage rating without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the UUE1H331MNS1MS replace the UUE1V331MNS1MS in my design?

A: The UUE1H331MNS1MS is mechanically and electrically compatible with identical capacitance, tolerance, package dimensions, and mounting characteristics. The substitute part has a higher voltage rating (50 V vs. 35 V), which is acceptable for direct substitution in applications designed for 35 V operation.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical case dimensions of 0.630" diameter (16.00mm), height of 0.689" (17.50mm), and surface mount land size of 0.673" L x 0.673" W (17.10mm x 17.10mm). They are fully compatible with the same PCB layout and reflow profile.

Q: What is the difference in ripple current specifications?

A: The UUE1H331MNS1MS has lower ripple current ratings (569.5 mA @ 120 Hz and 850 mA @ 100 kHz) compared to the main part (670 mA @ 120 Hz and 1 A @ 100 kHz). Circuit design must account for these specifications based on actual ripple current requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the UUE1V331MNS1MS and UUE1H331MNS1MS are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), suitable for automotive applications and standard reflow assembly processes.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -55°C to 125°C with a rated lifetime of 5000 hours at 125°C.
