Substitute Part Grouping Explanation

Substitute parts for the LQS2G331MELB35 are classified based on the following substitution criteria:

Upgrade Substitute (Higher Voltage Rating): LQSW6331MELB35 maintains identical capacitance (330 µF), tolerance (±20%), physical dimensions, lead spacing, and mounting configuration while providing an elevated voltage rating of 420 V. This part is suitable for applications where higher voltage margin is beneficial.

Parametric Equivalent (Same Series, Different Product Line): LGN2G331MELB35 matches all critical electrical parameters—capacitance (330 µF), tolerance (±20%), voltage rating (400 V), lifetime (3000 Hrs @ 105°C), and operating temperature range (-25°C ~ 105°C)—with identical mechanical specifications including package type, lead spacing, and physical dimensions. This part represents an alternative within the Nichicon product portfolio.

Direct Equivalent (Cross-Manufacturer): B43644B9337M000 from EPCOS - TDK Electronics provides equivalent capacitance (330 µF), tolerance (±20%), and voltage rating (400 V) with identical physical dimensions and lead spacing. This part offers extended lifetime (5000 Hrs @ 105°C) and wider operating temperature range (-40°C ~ 105°C), with documented ESR specification (280 mOhm @ 100Hz).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with modern manufacturing standards. Selection between substitutes depends on specific application requirements:

LQSW6331MELB35 is appropriate when circuit design benefits from increased voltage headroom at 420 V while maintaining identical physical footprint and Nichicon series continuity.

LGN2G331MELB35 provides parametric equivalence within the Nichicon portfolio, offering an alternative product line option with matching electrical and mechanical specifications.

B43644B9337M000 from EPCOS - TDK Electronics is suitable for applications requiring extended component lifetime (5000 Hrs @ 105°C versus 3000 Hrs) and expanded low-temperature operating range (-40°C minimum versus -25°C), with documented ESR characteristics for performance-critical circuits.

Frequently Asked Questions (FAQ)

Q: Can LQSW6331MELB35 be used as a direct replacement for LQS2G331MELB35?

A: Yes. LQSW6331MELB35 maintains identical capacitance, tolerance, physical dimensions, lead spacing, and mounting configuration. The 420 V rating provides higher voltage margin than the 400 V specification of the original part.

Q: What is the primary difference between LGN2G331MELB35 and LQS2G331MELB35?

A: Both parts are manufactured by Nichicon with identical electrical specifications (330 µF, ±20%, 400 V) and mechanical dimensions. The difference is the product series designation (LGN versus LQS), representing alternative product lines within Nichicon's portfolio.

Q: Is B43644B9337M000 compatible with the original circuit design?

A: Yes. B43644B9337M000 matches the capacitance, tolerance, voltage rating, physical dimensions, and lead spacing of LQS2G331MELB35. The extended lifetime (5000 Hrs @ 105°C) and wider temperature range (-40°C ~ 105°C) represent performance enhancements suitable for the same application.

Q: Are all substitute parts through-hole mounted with snap-in configuration?

A: Yes. All substitute parts use radial, can snap-in package with through-hole mounting and identical 10.00mm lead spacing, ensuring direct PCB compatibility.

Q: Do all parts meet current environmental compliance standards?

A: Yes. All listed parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.
