Substitute Part Grouping Explanation

Substitution of the 380LX331M250H042 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 250 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lead Spacing: 10.00 mm (exact match required)
• Physical Dimensions: 22.00 mm diameter, 42.00 mm height maximum (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

Compliance Parameters:

• RoHS3 Compliance (required for equivalent substitution)
• REACH Unaffected status (required for equivalent substitution)

The substitute part LGR2E331MELZ40 manufactured by Nichicon meets all mandatory matching parameters and compliance requirements, establishing it as a direct equivalent for the 380LX331M250H042 in applications where physical and electrical compatibility are required.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution Criteria:

The LGR2E331MELZ40 (Nichicon) is a direct equivalent to the 380LX331M250H042 (CDE) based on the following engineering factors:

1. Electrical Equivalence: Both parts share identical capacitance (330 µF), voltage rating (250 V), and tolerance (±20%), meeting the core electrical requirements for direct substitution in general-purpose applications.

2. Physical Compatibility: Lead spacing (10.00 mm), package dimensions (22.00 mm diameter, 42.00 mm height), and mounting type (through-hole, radial snap-in) are identical, ensuring PCB layout and mechanical compatibility without design modification.

3. Regulatory Compliance: Both parts are ROHS3 compliant and REACH unaffected, satisfying environmental and regulatory requirements for equivalent component selection.

4. Product Status: Both parts maintain active production status, supporting long-term supply chain reliability.

Performance Considerations:

The LGR2E331MELZ40 demonstrates enhanced performance characteristics in operating temperature range (-40°C ~ 105°C versus -40°C ~ 85°C) and lifetime rating (10000 Hrs @ 105°C versus 3000 Hrs @ 85°C). These characteristics do not disqualify substitution; they indicate the substitute part is suitable for applications with equivalent or less demanding thermal requirements.

The ripple current specification at 120 Hz is lower for the substitute part (1.2 A versus 1.66 A). Applications requiring the full ripple current capacity of the original part should retain the 380LX331M250H042.

Frequently Asked Questions (FAQ)

Q: Can the LGR2E331MELZ40 be used as a direct replacement for the 380LX331M250H042 on existing PCBs?

A: Yes. The LGR2E331MELZ40 is a direct equivalent. Both parts have identical lead spacing (10.00 mm), package dimensions (22.00 mm diameter, 42.00 mm height), and mounting type (through-hole radial snap-in). No PCB layout modification is required.

Q: Are there any electrical differences between these two parts?

A: Both parts have identical capacitance (330 µF), voltage rating (250 V), and tolerance (±20%). The ripple current at 120 Hz differs: 380LX331M250H042 is rated at 1.66 A, while LGR2E331MELZ40 is rated at 1.2 A. Applications requiring maximum ripple current capacity should use the original part.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 380LX331M250H042 and LGR2E331MELZ40 are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory requirements.

Q: What is the difference in operating temperature range?

A: The 380LX331M250H042 operates from -40°C to 85°C, while the LGR2E331MELZ40 operates from -40°C to 105°C. The substitute part supports a wider temperature range, making it suitable for applications within the original part's temperature specification.

Q: Why does the substitute part have a higher lifetime rating?

A: The LGR2E331MELZ40 is rated for 10000 Hrs @ 105°C, compared to 3000 Hrs @ 85°C for the 380LX331M250H042. This reflects different design and manufacturing approaches by Nichicon versus Cornell Dubilier Electronics. Both ratings are sufficient for general-purpose applications operating within their respective temperature specifications.

Q: Are both parts currently in stock?

A: Yes. The 380LX331M250H042 has 806 units in stock, and the LGR2E331MELZ40 has 961 units in stock, both listed as new original inventory.

Q: Can I use the LGR2E331MELZ40 in high-ripple-current applications?

A: The LGR2E331MELZ40 is rated for 1.2 A ripple current at 120 Hz, which is lower than the 380LX331M250H042 (1.66 A). For applications requiring the full ripple current capacity of the original part, the 380LX331M250H042 should be retained.
