Nichicon LGU2F331MELC 330µF 315V Aluminum Electrolytic Capacitor - Equivalent & Substitute Parts

Part Overview

The Nichicon LGU2F331MELC is a 330 µF, 315 V aluminum electrolytic capacitor in radial, can snap-in package configuration. This component is designed for general-purpose applications requiring through-hole mounting with a 10.00 mm lead spacing. The part is Active status and ROHS3 compliant, with a rated lifetime of 3000 hours at 105°C operating temperature. Substitute parts are necessary when inventory constraints exist, when alternative manufacturers are preferred for supply chain diversification, or when upgraded performance specifications are required for specific application demands.

Substitute Part Grouping Explanation

Substitute parts for the LGU2F331MELC are categorized into two groups based on electrical and mechanical compatibility:

Direct Equivalents (Same Electrical Specifications):

• LGU2F331MELB and LGU2F331MELZ are direct equivalents manufactured by Nichicon within the same LGU series
• All three parts maintain identical capacitance (330 µF), voltage rating (315 V), tolerance (±20%), and lifetime (3000 Hrs @ 105°C)
• Lead spacing remains constant at 10.00 mm across all direct equivalents
• Physical dimensions vary (can diameter and height), but all maintain radial, can snap-in package configuration and through-hole mounting compatibility
• All direct equivalents are ROHS3 compliant with identical operating temperature range (-25°C to 105°C)

Upgraded Alternatives (Higher Voltage Rating):

• B43508C9337M000 and B43644F9337M000 are manufactured by EPCOS - TDK Electronics
• These parts provide upgraded voltage rating of 400 V (versus 315 V in the main part)
• Capacitance remains 330 µF with ±20% tolerance
• Both maintain identical lead spacing (10.00 mm) and radial, can snap-in package configuration
• B43644F9337M000 offers extended lifetime of 5000 Hrs @ 105°C (versus 3000 Hrs)
• Operating temperature range extends to -40°C minimum (versus -25°C in the main part)
• Both upgraded alternatives are ROHS3 compliant

Parameter Comparison

Engineering Selection Recommendations

For Direct Equivalent Selection (LGU2F331MELB, LGU2F331MELZ): All three Nichicon LGU series parts are electrically and mechanically interchangeable. Selection among LGU2F331MELC, LGU2F331MELB, and LGU2F331MELZ depends on physical space constraints within the application. The main part (LGU2F331MELC) has a 35.00 mm diameter with 27.00 mm height. LGU2F331MELB offers a smaller 30.00 mm diameter but increased height of 32.00 mm. LGU2F331MELZ provides the smallest diameter at 22.00 mm but maximum height of 52.00 mm. All maintain identical electrical performance and compliance certifications.

For Upgraded Alternative Selection (B43508C9337M000, B43644F9337M000): The EPCOS - TDK Electronics alternatives provide 400 V voltage rating, suitable for applications requiring higher voltage margin or operating in elevated voltage environments. B43644F9337M000 is preferred when extended component lifetime is required, offering 5000 hours at 105°C versus 3000 hours in the main part and B43508C9337M000. Both upgraded alternatives support extended operating temperature range to -40°C, beneficial for applications in cold environments. All substitute parts maintain ROHS3 compliance and Active product status.

Frequently Asked Questions (FAQ)

Q: Can LGU2F331MELB and LGU2F331MELZ be used interchangeably with LGU2F331MELC? A: Yes. All three Nichicon LGU series parts share identical electrical specifications: 330 µF capacitance, 315 V voltage rating, ±20% tolerance, 3000 hour lifetime at 105°C, and 10.00 mm lead spacing. Physical dimensions differ, so verify available board space before selection.

Q: What is the primary difference between the Nichicon LGU series and EPCOS B43 series substitutes? A: The EPCOS B43 series parts provide upgraded 400 V voltage rating compared to 315 V in the Nichicon LGU series. Capacitance and tolerance remain identical at 330 µF and ±20%. B43644F9337M000 additionally offers extended 5000 hour lifetime versus 3000 hours.

Q: Are the EPCOS B43508C9337M000 and B43644F9337M000 direct replacements for LGU2F331MELC? A: Both EPCOS parts are mechanically compatible with identical lead spacing (10.00 mm), package type (radial, can snap-in), and mounting method (through hole). Electrically, they provide higher voltage rating (400 V) and extended operating temperature range (-40°C to 105°C). These characteristics make them suitable upgrades when higher voltage margin or wider temperature operation is required.

Q: Do all substitute parts maintain the same compliance certifications? A: Yes. All substitute parts listed are ROHS3 compliant and maintain Active product status. All are REACH unaffected and classified under ECCN EAR99 and HTSUS 8532.22.0040.

Q: What physical dimension considerations apply when selecting among direct equivalents? A: LGU2F331MELC (35.00 mm diameter, 27.00 mm height), LGU2F331MELB (30.00 mm diameter, 32.00 mm height), and LGU2F331MELZ (22.00 mm diameter, 52.00 mm height) occupy different board footprints. Verify available vertical and horizontal space in your application before substitution.

Q: Can I use a 400 V rated part in a 315 V application? A: Yes. The EPCOS B43 series parts rated at 400 V are suitable for applications designed for 315 V operation. Higher voltage rating provides additional safety margin and does not negatively impact circuit performance.
