Nichicon LGU2P471MELY Equivalent & Substitute Parts

Part Overview

The Nichicon LGU2P471MELY is a 470 µF, 220 V aluminum electrolytic capacitor in radial, can snap-in package configuration. This component is designed for general-purpose applications requiring high-voltage energy storage and filtering. The part maintains Active product status with ROHS3 compliance and carries a 3000-hour lifetime rating at 105°C operating temperature.

Substitute Part Grouping Explanation

Substitution eligibility for the LGU2P471MELY is determined by strict equivalence across the following critical parameters:

Capacitance: 470 µF (exact match required)
Voltage Rating: 220 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)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Manufacturer: Nichicon (same manufacturer)
Compliance: ROHS3 Compliant (exact match required)

All identified substitute parts meet these criteria. Variations in physical dimensions (diameter and height) are permissible provided the lead spacing and mounting footprint remain compatible with the circuit board design.

Engineering Selection Recommendations

All four parts maintain Active product status with ROHS3 compliance and identical electrical specifications. Selection between LGU2P471MELY and its substitutes is determined by physical space constraints within the application:

LGU2P471MELY (20 mm diameter, 50 mm height): Select when maximum height clearance is available and compact radial footprint is not a constraint.
LGN2P471MELY45 (20 mm diameter, 47 mm height): Select as a direct dimensional alternative to LGU2P471MELY with marginally reduced height. Ripple current performance is equivalent within specified tolerances.
LGU2P471MELA (25 mm diameter, 35 mm height): Select when height reduction is required and additional radial space is available. Maintains identical electrical performance.
LGU2P471MELB (30 mm diameter, 25 mm height): Select for applications with severe height constraints. Provides the most compact vertical profile while maintaining all electrical and compliance specifications.

All parts are manufactured by Nichicon, carry identical electrical ratings, and are suitable for direct substitution provided circuit board layout accommodates the physical dimensions.

Frequently Asked Questions (FAQ)

Q: Can LGU2P471MELB replace LGU2P471MELY in any application?

A: Yes, provided the circuit board layout accommodates the larger 30 mm diameter and reduced 25 mm height. All electrical parameters, voltage rating, capacitance, and compliance specifications are identical.

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

A: Both series are manufactured by Nichicon and meet identical electrical and compliance requirements for this 470 µF, 220 V specification. Series designation reflects internal manufacturing or design revision; substitution is valid based on matching electrical and mechanical parameters.

Q: Are there restrictions on substituting between these parts based on ripple current?

A: No. Ripple current values across all four parts (1.45–1.48 A @ 120 Hz and 2.175–2.22 A @ 50 kHz) fall within acceptable tolerance for general-purpose applications. Selection should be based on physical space availability and lead spacing compatibility.

Q: Does the 3 mm height difference between LGU2P471MELY and LGN2P471MELY45 affect electrical performance?

A: No. Height variation reflects internal construction differences but does not alter capacitance, voltage rating, tolerance, lifetime, or operating temperature range. Both parts are electrically equivalent.

Q: Can these parts be used interchangeably in high-ripple-current applications?

A: Yes, provided the application ripple current does not exceed the specified ratings. All four parts carry identical ripple current specifications and are suitable for equivalent thermal and electrical stress conditions.

Q: What is the significance of the lead spacing specification?

A: Lead spacing of 0.394" (10.00 mm) is identical across all four parts and determines circuit board hole pattern compatibility. This parameter must match the PCB design; all listed substitutes maintain this specification.
