LNT2G331MSECBN Equivalent & Substitute Parts

Part Overview

The LNT2G331MSECBN is a 330 µF, 400 V aluminum electrolytic capacitor manufactured by Nichicon in the LNT series. This radial, can-style capacitor with screw terminals is designed for general-purpose applications requiring high voltage energy storage and filtering. The part is rated for 5000 hours at 105°C operating temperature and maintains active product status with full RoHS3 compliance. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or design flexibility within the allowed parameter ranges.

Substitute Part Grouping Explanation

Substitution of the LNT2G331MSECBN is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 400 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package configuration: Radial, Can - Screw Terminals (exact match required)
• Mounting type: Chassis Mount (exact match required)
• Physical dimensions: Lead spacing 0.500" (12.70mm), case diameter 1.378" (35.00mm), height 3.268" (83.00mm) (exact match required)
• Operating temperature range: -25°C ~ 105°C (exact match required)
• Lifetime rating: 5000 Hrs @ 105°C (exact match required)
• Compliance: RoHS3 Compliant (exact match required)

The LNT2G331MSEC qualifies as a parametric equivalent substitute based on full alignment with all specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the LNT2G331MSECBN and LNT2G331MSEC are active products manufactured by Nichicon with full RoHS3 compliance and REACH compliance status. Selection between these parts is based on availability and application-specific ripple current requirements at 10 kHz, where the main part (LNT2G331MSECBN) provides 3.22 A and the substitute (LNT2G331MSEC) provides 2.645 A. All other electrical, mechanical, and compliance parameters are identical. Both parts are suitable for general-purpose high-voltage filtering applications in chassis-mounted configurations.

Frequently Asked Questions (FAQ)

Q: Can LNT2G331MSEC be used as a direct replacement for LNT2G331MSECBN?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (400 V), tolerance (±20%), operating temperature range (-25°C ~ 105°C), lifetime rating (5000 Hrs @ 105°C), physical dimensions, package configuration (Radial, Can - Screw Terminals), and compliance certifications (RoHS3, REACH). The ripple current at 10 kHz differs slightly (2.645 A vs. 3.22 A), but both meet the specified 120 Hz ripple current requirement of 2.3 A.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical lead spacing (0.500" / 12.70mm), case diameter (1.378" / 35.00mm), and seated height (3.268" / 83.00mm). They are mechanically interchangeable in chassis-mount applications.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both LNT2G331MSECBN and LNT2G331MSEC are RoHS3 compliant and REACH affected, with identical environmental and regulatory status.

Q: What is the difference in ripple current specifications?

A: The main part LNT2G331MSECBN is rated for 3.22 A ripple current at 10 kHz, while the substitute LNT2G331MSEC is rated for 2.645 A at 10 kHz. Both meet the 2.3 A ripple current specification at 120 Hz. Selection should be based on the specific ripple current demands of the application at high frequency.
