Substitute Part Grouping Explanation

The LNT2V331MSEC qualifies for substitution with the LNT2G331MSEC based on the following criteria:

Matching Parameters (Substitution Basis):

• Identical capacitance value: 330 µF
• Identical tolerance: ±20%
• Identical lifetime rating: 5000 Hrs @ 105°C
• Identical operating temperature range: -25°C ~ 105°C
• Identical polarization: Polar
• Identical package type: Radial, Can - Screw Terminals
• Identical mechanical dimensions: 1.378" Dia, 3.268" Height, 0.500" lead spacing
• Identical mounting type: Chassis Mount
• Identical series: LNT
• Identical compliance: ROHS3 Compliant

Differentiating Parameter:

• Voltage rating: LNT2V331MSEC operates at 350 V; LNT2G331MSEC operates at 400 V

The substitute part provides a higher voltage rating while maintaining all other electrical and mechanical specifications, enabling direct mechanical and electrical compatibility with enhanced voltage margin capability.

Parameter Comparison

Engineering Selection Recommendations

Both the LNT2V331MSEC and LNT2G331MSEC are Active status components manufactured by Nichicon and carry ROHS3 compliance certification. The LNT2G331MSEC substitute provides a 50 V higher voltage rating (400 V vs. 350 V) while maintaining identical mechanical form factor, lead spacing, and thermal characteristics. This higher voltage rating creates an additional safety margin in applications where the circuit voltage remains at or below 350 V.

Selection between these parts depends on circuit voltage requirements and inventory availability. The substitute part is electrically and mechanically interchangeable for applications designed for 350 V operation, with the added benefit of higher voltage withstand capability.

Frequently Asked Questions (FAQ)

Q: Can LNT2G331MSEC replace LNT2V331MSEC in my circuit?

A: Yes. The LNT2G331MSEC is mechanically and electrically compatible with the LNT2V331MSEC. Both parts share identical capacitance (330 µF), tolerance (±20%), package type (Radial, Can - Screw Terminals), mechanical dimensions, and thermal ratings. The substitute provides a higher voltage rating (400 V vs. 350 V), which is compatible with circuits designed for 350 V operation.

Q: What is the key difference between these two parts?

A: The primary difference is the voltage rating. The LNT2V331MSEC is rated for 350 V, while the LNT2G331MSEC is rated for 400 V. All other specifications, including capacitance, tolerance, package, dimensions, and thermal characteristics, are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical mechanical specifications: 1.378" diameter, 3.268" maximum seated height, 0.500" lead spacing, and Radial, Can - Screw Terminals package type. They are direct mechanical replacements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LNT2V331MSEC and LNT2G331MSEC are ROHS3 compliant and carry Active product status from Nichicon.

Q: What are the ripple current ratings for each part?

A: LNT2V331MSEC: 2.1 A @ 120 Hz, 2.94 A @ 10 kHz. LNT2G331MSEC: 2.3 A @ 120 Hz, 2.645 A @ 10 kHz. Both parts handle ripple current within their respective voltage ratings.
