LGU2P331MELA Equivalent & Substitute Parts

Part Overview

The LGU2P331MELA is a 330 µF, 220 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Nichicon. This component is rated for 3000 hours at 105°C and is designed for general purpose applications requiring through-hole mounting. The part is Active status and ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, design flexibility, or application-specific voltage and ripple current requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LGU2P331MELA is determined by the following criteria:

Electrical Parameters (Must Match or Exceed):

• Capacitance: 330 µF (fixed requirement)
• Tolerance: ±20% (fixed requirement)
• Voltage Rating: Minimum 220 V (equal or higher voltage rating is acceptable)
• Lifetime: 3000 Hrs @ 105°C (fixed requirement)
• Operating Temperature: -40°C ~ 105°C (fixed requirement)
• Ripple Current: Must meet or exceed 1.25 A @ 120 Hz and 1.875 A @ 50 kHz

Mechanical Parameters (Must Match):

• Lead Spacing: 0.394" (10.00 mm)
• Mounting Type: Through Hole
• Package / Case: Radial, Can - Snap-In
• Polarization: Polar

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Product Status: Active

Substitute parts are grouped into two categories: Upgrade substitutes (higher voltage rating) and Similar substitutes (equivalent voltage rating with dimensional variations).

Parameter Comparison

Engineering Selection Recommendations

LGW2E331MELA25 (Upgrade Substitute): This part provides a voltage rating upgrade from 220 V to 250 V while maintaining identical capacitance, tolerance, and thermal specifications. Ripple current performance is enhanced (1.8 A @ 120 Hz, 2.7 A @ 50 kHz). Physical dimensions and lead spacing remain compatible. This substitute is suitable for applications requiring higher voltage margin or increased ripple current handling. All compliance certifications (ROHS3) are maintained.

LGN2P331MELZ25 (Similar Substitute): This part maintains the 220 V voltage rating and equivalent electrical specifications. Dimensional differences exist: smaller diameter (0.866" vs 0.984") and increased height (1.063" vs 0.984"). Lead spacing remains 10.00 mm. Ripple current performance is equivalent (1.26 A @ 120 Hz, 1.89 A @ 50 kHz). Selection requires PCB layout verification for height clearance. All compliance certifications are maintained.

LGU2E331MELA (Similar Substitute): This part provides a voltage rating upgrade to 250 V with identical capacitance and tolerance. Height increases to 1.181" (30.00 mm) while diameter remains 0.984". Ripple current performance is enhanced (1.3 A @ 120 Hz, 1.95 A @ 50 kHz). Lead spacing remains 10.00 mm. Selection requires PCB layout verification for height clearance. All compliance certifications are maintained.

LGU2P331MELZ (Similar Substitute): This part maintains the 220 V voltage rating and equivalent electrical specifications. Dimensional differences exist: smaller diameter (0.866" vs 0.984") and significantly increased height (1.378" vs 0.984"). Lead spacing remains 10.00 mm. Ripple current performance is equivalent (1.25 A @ 120 Hz, 1.875 A @ 50 kHz). Selection requires PCB layout verification for height clearance. All compliance certifications are maintained.

Frequently Asked Questions (FAQ)

Q: Can LGW2E331MELA25 be used as a direct replacement for LGU2P331MELA?

A: Yes. LGW2E331MELA25 is electrically and mechanically compatible. The 250 V rating exceeds the 220 V requirement, and all other parameters (capacitance, tolerance, lifetime, operating temperature, lead spacing, package type) are identical. Physical dimensions are also identical (0.984" diameter, 0.984" height).

Q: What are the dimensional constraints when selecting substitute parts?

A: The main part has a diameter of 0.984" and height of 0.984". LGN2P331MELZ25 and LGU2P331MELZ have smaller diameters (0.866") but greater heights (1.063" and 1.378" respectively). LGU2E331MELA maintains the 0.984" diameter but increases height to 1.181". PCB layout must accommodate these dimensional variations, particularly height clearance above the board.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (LGW2E331MELA25, LGN2P331MELZ25, LGU2E331MELA, LGU2P331MELZ) are ROHS3 compliant and maintain Active product status.

Q: What is the difference between Upgrade and Similar substitutes?

A: Upgrade substitutes (LGW2E331MELA25) provide higher voltage ratings (250 V vs 220 V) with enhanced ripple current performance and identical physical dimensions. Similar substitutes maintain the original voltage rating but may have dimensional variations in diameter and/or height.

Q: Can I use a 250 V rated part in a 220 V application?

A: Yes. A higher voltage rating is acceptable in applications designed for lower voltage. The 250 V parts (LGW2E331MELA25, LGU2E331MELA) are suitable for 220 V applications.

Q: Do all substitute parts have the same lead spacing?

A: Yes. All substitute parts maintain the 0.394" (10.00 mm) lead spacing, ensuring PCB footprint compatibility.

Q: What ripple current performance differences exist among substitutes?

A: LGW2E331MELA25 provides the highest ripple current (1.8 A @ 120 Hz, 2.7 A @ 50 kHz). LGU2E331MELA provides intermediate performance (1.3 A @ 120 Hz, 1.95 A @ 50 kHz). LGN2P331MELZ25 and LGU2P331MELZ provide equivalent performance to the main part (approximately 1.25-1.26 A @ 120 Hz, 1.875-1.89 A @ 50 kHz).
