LGJ2C331MELB15 Equivalent & Substitute Parts

Part Overview

The LGJ2C331MELB15 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 through-hole mounting. The part is currently active in production with ROHS3 compliance and REACH unaffected status. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same product category, enabling component sourcing flexibility while preserving circuit performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for aluminum electrolytic capacitors is determined by matching the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 160 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting type: Through Hole (exact match required)
• Package style: Radial, Can - Snap-In (exact match required)
• Lead spacing: 0.394" (10.00 mm) (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Compliance certifications: ROHS3 Compliant, REACH Unaffected (exact match required)

The LGU2C331MELY meets all substitution criteria. Variations in lifetime rating, ripple current specifications, and physical dimensions (diameter and height) do not preclude substitution when the core electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both LGJ2C331MELB15 and LGU2C331MELY are active production parts from Nichicon with identical electrical specifications and mechanical compatibility. Selection between these parts is based on application requirements and inventory availability:

The LGJ2C331MELB15 is suitable for applications where the specified 2000 Hrs @ 105°C lifetime and physical dimensions (30.00 mm diameter, 17.00 mm height) align with circuit board layout constraints.

The LGU2C331MELY is suitable for applications where extended lifetime (3000 Hrs @ 105°C) and higher ripple current handling (1.2 A @ 120 Hz, 1.8 A @ 50 kHz) provide operational margin. Physical dimensions differ (20.00 mm diameter, 30.00 mm height), requiring board layout verification.

Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can LGU2C331MELY replace LGJ2C331MELB15 in existing designs?

A: Yes, provided that printed circuit board layout accommodates the different physical dimensions. The LGU2C331MELY has a smaller diameter (20.00 mm vs. 30.00 mm) but greater height (30.00 mm vs. 17.00 mm). All electrical parameters, voltage rating, capacitance, tolerance, and lead spacing are identical.

Q: What is the significance of the different lifetime ratings?

A: The LGJ2C331MELB15 is rated for 2000 Hrs @ 105°C, while the LGU2C331MELY is rated for 3000 Hrs @ 105°C. Both ratings are provided by the manufacturer for their respective series. Selection depends on application duty cycle and expected service life requirements.

Q: Are the ripple current differences important for substitution?

A: Ripple current specifications indicate the maximum AC current the capacitor can handle at specified frequencies. The LGU2C331MELY has higher ripple current ratings (1.2 A @ 120 Hz vs. 1 A, and 1.8 A @ 50 kHz vs. 1.5 A). If the application requires ripple current handling within the LGJ2C331MELB15 specification, either part is acceptable. If ripple current exceeds LGJ2C331MELB15 limits, the LGU2C331MELY provides additional margin.

Q: Do both parts have the same lead spacing?

A: Yes. Both parts have 0.394" (10.00 mm) lead spacing, ensuring compatibility with identically designed through-hole footprints on printed circuit boards.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.
