LGJ2C331MELA Equivalent & Substitute Parts

Part Overview

The LGJ2C331MELA is a 330 µF, 160 V aluminum electrolytic capacitor manufactured by Nichicon in the LGJ series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring stable capacitance performance across extended operating temperatures. The part is Active status and ROHS3 compliant, making it suitable for modern electronic equipment. Substitute parts are identified when original inventory is unavailable or when design flexibility permits selection from equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LGJ2C331MELA is determined by strict equivalence in the following parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 160 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime: 3000 Hrs @ 105°C (exact match required)
• Operating Temperature: -40°C ~ 105°C (exact match required)
• Polarization: Polar (exact match required)
• Lead Spacing: 0.394" (10.00 mm) (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)

The LGU2C331MELY qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Differences in physical dimensions (diameter and height) and ripple current ratings do not preclude substitution when the snap-in mounting interface and lead spacing remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the LGJ2C331MELA and LGU2C331MELY are Active status products manufactured by Nichicon with ROHS3 compliance and REACH unaffected status. Selection between these parts is based on physical space constraints and ripple current requirements within the application circuit.

The LGJ2C331MELA features a larger diameter (25.00 mm) with reduced height (22.00 mm) and lower ripple current specifications (1.02 A @ 120 Hz, 1.53 A @ 50 kHz). The LGU2C331MELY provides a smaller diameter (20.00 mm) with increased height (30.00 mm) and higher ripple current capacity (1.2 A @ 120 Hz, 1.8 A @ 50 kHz). Both parts maintain identical electrical performance in capacitance, voltage rating, tolerance, and thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can LGU2C331MELY replace LGJ2C331MELA in my circuit?

A: Yes, provided that the physical dimensions fit within your PCB layout constraints. Both parts share identical capacitance (330 µF), voltage rating (160 V), tolerance (±20%), operating temperature range (-40°C ~ 105°C), and lead spacing (10.00 mm). The LGU2C331MELY has a smaller diameter but greater height, so verify clearance in your specific application.

Q: What is the difference in ripple current handling?

A: The LGU2C331MELY supports higher ripple current at both low frequency (1.2 A @ 120 Hz versus 1.02 A) and high frequency (1.8 A @ 50 kHz versus 1.53 A). If your circuit requires higher ripple current capacity, the LGU2C331MELY is the appropriate selection.

Q: Are both parts RoHS compliant?

A: Yes, both LGJ2C331MELA and LGU2C331MELY are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Does the physical size difference affect electrical performance?

A: No. The difference in diameter and height does not alter the electrical characteristics. Both parts deliver identical capacitance, voltage rating, tolerance, and thermal performance. Size selection is determined by available PCB space and mounting constraints.

Q: What is the snap-in mounting interface?

A: Both parts use radial, can-style snap-in packaging with through-hole mounting. The 10.00 mm lead spacing is identical on both parts, ensuring compatibility with standard snap-in receptacles designed for this pitch.
