LGU2C561MELZ Equivalent & Substitute Parts

Part Overview

The LGU2C561MELZ is a 560 µF, 160 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Nichicon. This component is classified as Active product status and is designed for general-purpose applications requiring stable capacitance and extended operational life. The part is ROHS3 compliant and REACH unaffected, making it suitable for modern electronic equipment.

Substitute parts become necessary when the primary part experiences supply constraints, inventory limitations, or when design flexibility allows for alternative configurations that maintain electrical and mechanical compatibility within the application's tolerance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LGU2C561MELZ is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Capacitance: 560 µF (fixed requirement)
• Tolerance: ±20% (fixed requirement)
• Voltage Rating: 160 V minimum (equal or higher voltage rating is acceptable)
• Operating Temperature: -40°C ~ 105°C (must match or exceed range)
• Lifetime: 3000 Hrs @ 105°C (must meet or exceed)

Mechanical Compatibility Requirements:

• Lead Spacing: 0.394" (10.00 mm) (fixed requirement for PCB hole alignment)
• Mounting Type: Through Hole (fixed requirement)
• Package / Case: Radial, Can - Snap-In (fixed requirement)

Compliance Requirements:

• RoHS Status: ROHS3 Compliant (mandatory)
• REACH Status: REACH Unaffected (mandatory)

Substitute parts may vary in case diameter and seated height provided that the lead spacing, mounting type, and package configuration remain constant. Voltage ratings equal to or exceeding 160 V are acceptable. Ripple current specifications may vary within the electrical design envelope of the application.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with the original LGU2C561MELZ specification.

LGN2C561MELY35 and LGN2C561MELZ30: These parts are electrically equivalent with identical capacitance, tolerance, voltage rating, and lifetime specifications. The LGN series differs in case diameter and height dimensions. LGN2C561MELZ30 maintains the same 22.00 mm case diameter as the primary part with reduced height (32.00 mm vs. 35.00 mm), offering space optimization. LGN2C561MELY35 features a smaller 20.00 mm diameter with increased height (37.00 mm). Both are suitable where PCB layout accommodates dimensional variation.

LGU2C561MELA: This part maintains the LGU series electrical characteristics with identical ripple current ratings. The case diameter increases to 25.00 mm with reduced height to 30.00 mm. Selection depends on available PCB footprint space and mounting clearance.

LGU2Z561MELZ: This part provides elevated voltage rating (180 V vs. 160 V) while maintaining identical capacitance, tolerance, and lifetime. The increased voltage rating provides additional design margin in high-voltage applications. Height increases to 40.00 mm. This part is suitable for applications where higher voltage tolerance is beneficial or required.

Frequently Asked Questions (FAQ)

Q: Can I substitute LGU2Z561MELZ (180 V) for LGU2C561MELZ (160 V)?

A: Yes. The LGU2Z561MELZ provides equivalent electrical performance with higher voltage rating. Higher voltage-rated capacitors are backward compatible in lower voltage applications. Verify that the increased height (40.00 mm vs. 35.00 mm) accommodates your PCB layout and mounting clearance.

Q: What is the difference between LGN and LGU series parts?

A: Both series are Nichicon aluminum electrolytic capacitors with identical electrical specifications for the 560 µF, 160 V configuration. The series designation reflects internal design variations that result in different case dimensions. Selection between series depends on available PCB space and mounting constraints.

Q: Are all substitute parts pin-compatible with the original LGU2C561MELZ?

A: Yes. All substitute parts maintain the 0.394" (10.00 mm) lead spacing and through-hole radial, snap-in package configuration. PCB hole patterns remain compatible. Verify that case diameter and height variations do not conflict with component placement or clearance requirements.

Q: Can I use LGN2C561MELY35 in a space-constrained application?

A: LGN2C561MELY35 features a smaller case diameter (20.00 mm vs. 22.00 mm) but increased height (37.00 mm vs. 35.00 mm). Evaluate your specific spatial constraints. If height is limited, LGN2C561MELZ30 or LGU2C561MELA may be more suitable.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the original part's regulatory status.

Q: What is the impact of different ripple current ratings?

A: LGU series parts (LGU2C561MELZ, LGU2C561MELA, LGU2Z561MELZ) provide higher ripple current capacity (1.67 A @ 120 Hz, 2.505 A @ 50 kHz) compared to LGN series parts (1.5 A @ 120 Hz, 2.25 A @ 50 kHz). Select based on your circuit's ripple current requirements. Higher ripple current capability provides additional thermal margin.
