LNT2V331MSECBN Equivalent & Substitute Parts

Part Overview

The LNT2V331MSECBN is a 330 µF, 350 V aluminum electrolytic capacitor manufactured by Nichicon in the LNT series. This radial, can-style component features screw terminals for chassis mount applications and is rated for 5000 hours at 105°C. The part is Active status and ROHS3 compliant, making it suitable for general-purpose power supply and energy storage applications requiring reliable long-term performance.

Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and application requirements where voltage ratings or performance characteristics may differ from the primary specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the LNT2V331MSECBN is determined by the following allowable parameters:

• Capacitance: Must remain 330 µF (±20% tolerance maintained)
• Voltage Rating: Substitute parts must meet or exceed 350 V
• Package / Case: Must be Radial, Can - Screw Terminals
• Mounting Type: Must be Chassis Mount
• Physical Dimensions: Lead spacing, diameter, and height must match or be compatible with the original footprint
• Polarization: Must remain Polar
• Operating Temperature Range: Must support -25°C ~ 105°C minimum
• Lifetime Rating: Must support 5000 Hrs @ 105°C minimum
• Compliance: Must maintain ROHS3 compliance

The LNT2G331MSEC qualifies as an upgrade substitute due to its higher 400 V voltage rating while maintaining all other critical parameters. The LNT2V331MSEC is a parametric equivalent with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

LNT2G331MSEC (Upgrade Substitute): This part provides a higher voltage rating of 400 V while maintaining identical physical dimensions, capacitance, and thermal characteristics. Selection of this upgrade is appropriate for applications where increased voltage margin is beneficial or where circuit design permits higher voltage tolerance. All compliance certifications (ROHS3, REACH Affected, EAR99) remain consistent with the original specification.

LNT2V331MSEC (Parametric Equivalent): This part is electrically and mechanically identical to the LNT2V331MSECBN, differing only in packaging designation (bulk vs. specific terminal configuration). This equivalent maintains full compatibility with the original design and is suitable for direct replacement in all applications. Compliance status remains unchanged.

Both substitute parts are Active status products with confirmed inventory availability, supporting uninterrupted supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the LNT2G331MSEC (400 V) be used in place of the LNT2V331MSECBN (350 V)?

A: Yes. The LNT2G331MSEC is a direct mechanical and dimensional substitute with a higher voltage rating. Higher voltage-rated capacitors are backward compatible in circuits designed for lower voltages, provided the circuit topology and component placement remain unchanged.

Q: What is the difference between LNT2V331MSECBN and LNT2V331MSEC?

A: These parts are parametric equivalents with identical electrical specifications and physical dimensions. The designation difference reflects packaging or distribution channel variation. Both are suitable for direct substitution.

Q: Are all three parts interchangeable in the same PCB footprint?

A: Yes. All three parts share identical lead spacing (0.500"), diameter (1.378"), height (3.268"), and screw terminal configuration, ensuring mechanical compatibility in chassis mount applications.

Q: Do substitute parts maintain the same thermal performance?

A: Yes. All substitute parts maintain the 5000 Hrs @ 105°C lifetime rating and -25°C ~ 105°C operating temperature range, ensuring equivalent thermal performance in the application.

Q: Are there any compliance differences between the main part and substitutes?

A: No. All parts maintain ROHS3 compliance, REACH Affected status, and EAR99 ECCN classification, ensuring consistent regulatory compliance across substitution options.
