LNT2H331MSEFBB Equivalent & Substitute Parts

Part Overview

The LNT2H331MSEFBB is a 330 µF, 500 V aluminum electrolytic capacitor manufactured by Nichicon, designed for general purpose applications requiring high voltage energy storage and filtering. This radial, can-style capacitor with screw terminals is rated for 2000 hours at 105°C operating temperature and supports ripple currents up to 3.78 A at 10 kHz. The part is currently active in production with ROHS3 compliance and REACH affected status. Substitute parts are identified when equivalent electrical and mechanical specifications are maintained across the same series and packaging configuration.

Substitute Part Grouping Explanation

Substitution eligibility for the LNT2H331MSEFBB is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Rated voltage: 500 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime rating: 2000 Hrs @ 105°C (exact match required)
• Operating temperature range: -25°C ~ 105°C (exact match required)
• Ripple current specifications: 2.7 A @ 120 Hz and 3.78 A @ 10 kHz (exact match required)
• Physical dimensions: 2.008" Dia (51.00 mm), 3.268" Height (83.00 mm), 0.866" lead spacing (exact match required)
• Package configuration: Radial, Can - Screw Terminals, Chassis Mount (exact match required)
• Series designation: LNT (same series required)
• Compliance certifications: ROHS3 Compliant, REACH Affected (exact match required)

Substitute parts must originate from the same manufacturer (Nichicon) and maintain identical electrical performance and mechanical compatibility to ensure direct interchangeability without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

Both the LNT2H331MSEFBB and LNT2H331MSEF are active production parts from Nichicon with identical electrical and mechanical specifications. Selection between these parts is based on packaging and inventory availability rather than technical performance differences. Both parts maintain ROHS3 compliance and REACH affected status, ensuring regulatory alignment for industrial and commercial applications. The LNT2H331MSEF variant offers higher current inventory (1047 Pcs) compared to the LNT2H331MSEFBB (871 Pcs), which may influence procurement decisions for high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can LNT2H331MSEF be used as a direct replacement for LNT2H331MSEFBB?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications, including capacitance, voltage rating, tolerance, temperature performance, ripple current ratings, physical dimensions, and package configuration. Direct substitution is supported without circuit modification or board layout changes.

Q: What determines substitution eligibility for this capacitor?

A: Substitution requires exact equivalence in capacitance (330 µF), rated voltage (500 V), tolerance (±20%), lifetime rating (2000 Hrs @ 105°C), operating temperature range (-25°C ~ 105°C), ripple current specifications (2.7 A @ 120 Hz, 3.78 A @ 10 kHz), physical dimensions (2.008" Dia, 3.268" Height, 0.866" lead spacing), package type (Radial, Can - Screw Terminals), and compliance certifications (ROHS3, REACH).

Q: Are there any differences in packaging between LNT2H331MSEFBB and LNT2H331MSEF?

A: Both parts use identical packaging: Radial, Can - Screw Terminals with Chassis Mount configuration. The designation difference reflects internal Nichicon part numbering conventions but does not indicate packaging or performance variations.

Q: What is the significance of the LNT series designation?

A: The LNT series identifies the product line within Nichicon's aluminum electrolytic capacitor portfolio. Substitute parts must maintain the same series designation to ensure consistency in manufacturing standards, performance characteristics, and reliability ratings.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both LNT2H331MSEFBB and LNT2H331MSEF are ROHS3 compliant and REACH affected, meeting current environmental and hazardous substance regulations for industrial component applications.
