Nichicon LGG2P331MELZ25 Equivalent & Substitute Parts

Part Overview

The Nichicon LGG2P331MELZ25 is a 330 µF, 220 V aluminum electrolytic capacitor in a radial, can snap-in package designed for general purpose applications. This through-hole mounted component operates across a temperature range of -40°C to 105°C with a rated lifetime of 2000 hours at 105°C. The part is ROHS3 compliant and currently active in production. Substitute parts are identified to address inventory availability, extended operational lifetime requirements, or specific application constraints while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LGG2P331MELZ25 is determined by strict equivalence in the following parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 220 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.394" (10.00 mm) (exact match required)
• Operating Temperature Range: -40°C to 105°C (exact match required)

Variations in lifetime rating, ripple current specifications, physical height, and series designation do not preclude substitution when all primary electrical and mechanical parameters are identical. The identified substitute parts meet all mandatory equivalence criteria.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts—LGN2P331MELZ25 and LGU2P331MELZ—are electrically and mechanically equivalent to the LGG2P331MELZ25 and are suitable for direct replacement in applications requiring 330 µF, 220 V aluminum electrolytic capacitors with snap-in mounting.

LGN2P331MELZ25 maintains identical physical dimensions (1.063" seated height) and electrical performance characteristics to the main part while offering extended operational lifetime (3000 hours at 105°C versus 2000 hours). All three parts are ROHS3 compliant and REACH unaffected.

LGU2P331MELZ provides equivalent electrical specifications with extended lifetime (3000 hours at 105°C). The physical height differs at 1.378" seated height compared to 1.063" for the main part. Ripple current specifications are marginally lower (1.25 A @ 120 Hz and 1.875 A @ 50 kHz versus 1.26 A and 1.89 A respectively). This part remains ROHS3 compliant and REACH unaffected.

Selection between these substitutes depends on available inventory, physical space constraints within the application, and ripple current requirements specific to the circuit design.

Frequently Asked Questions (FAQ)

Q: Can LGN2P331MELZ25 be used as a direct replacement for LGG2P331MELZ25?

A: Yes. The LGN2P331MELZ25 is electrically and mechanically equivalent. It maintains identical capacitance (330 µF), voltage rating (220 V), tolerance (±20%), package type (radial snap-in), lead spacing (10.00 mm), and physical height (1.063"). The extended lifetime rating (3000 hours at 105°C) does not affect compatibility.

Q: What is the primary difference between LGU2P331MELZ and the main part?

A: The LGU2P331MELZ differs in physical height (1.378" versus 1.063" seated height) and has marginally lower ripple current specifications (1.25 A @ 120 Hz and 1.875 A @ 50 kHz). All other electrical and mechanical parameters are equivalent. Space constraints within the application enclosure must be evaluated before selection.

Q: Are all three parts ROHS3 compliant?

A: Yes. The LGG2P331MELZ25, LGN2P331MELZ25, and LGU2P331MELZ are all ROHS3 compliant and REACH unaffected.

Q: Does the extended lifetime of substitute parts affect circuit performance?

A: No. Extended lifetime ratings indicate longer operational durability under specified thermal conditions but do not alter electrical performance, capacitance, voltage rating, or ripple current handling within the rated specifications.

Q: Can these parts be used interchangeably on the same PCB?

A: LGG2P331MELZ25 and LGN2P331MELZ25 can be used interchangeably due to identical physical dimensions and lead spacing. LGU2P331MELZ requires verification of available vertical space due to its increased height (1.378" versus 1.063").
