Nichicon LGU2F471MELC Equivalent & Substitute Parts

Part Overview

The Nichicon LGU2F471MELC is a 470 µF, 315 V aluminum electrolytic capacitor in radial, can snap-in package configuration. This component is designed for general-purpose applications requiring stable capacitance performance across extended operating temperatures from -25°C to 105°C with a rated lifetime of 3000 hours at 105°C. The part maintains Active product status with full ROHS3 compliance and REACH unaffected designation.

Equivalent and substitute parts are identified based on matching or exceeding the core electrical and mechanical specifications of the main part, enabling direct replacement or upgrade scenarios in circuit designs where the original part may be unavailable or where enhanced voltage ratings are required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LGU2F471MELC are classified into two categories based on substitution logic:

Upgrade Substitutes (Higher Voltage Rating): Parts with identical capacitance (470 µF), tolerance (±20%), identical or superior physical dimensions, and voltage ratings equal to or exceeding 315 V. These parts provide enhanced voltage margin and are direct functional upgrades.

Similar Substitutes (Same Electrical Specifications, Dimensional Variants): Parts with identical capacitance, tolerance, voltage rating, and operating temperature range but with different physical dimensions. These require PCB layout verification for lead spacing and case diameter compatibility.

Key Parameters Determining Substitutability:

• Capacitance value: 470 µF (fixed requirement)
• Tolerance: ±20% (fixed requirement)
• Voltage rating: ≥315 V (equal or higher acceptable)
• Lead spacing: 0.394" (10.00 mm) (fixed requirement)
• Package type: Radial, Can - Snap-In (fixed requirement)
• Mounting type: Through Hole (fixed requirement)
• Operating temperature range: -25°C to 105°C (fixed requirement)

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Same Footprint): LGN2V471MELC30, 400MXK470MEFCSN35X30, and EKMS401VSN471MA30S are direct physical replacements with identical case diameter (1.378" / 35.00 mm) and height (1.260" / 32.00 mm). All three parts maintain Active product status with full compliance certifications (ROHS3 or RoHS Compliant, REACH Unaffected). The upgrade parts provide enhanced voltage ratings (350 V or 400 V) compared to the original 315 V specification, offering increased design margin without PCB modification.

Dimensional Variant Substitutes (PCB Layout Verification Required): LGU2F471MELA and LGU2F471MELB maintain identical electrical specifications but feature different physical dimensions. LGU2F471MELA has a smaller diameter (0.984" / 25.00 mm) with increased height (2.047" / 52.00 mm). LGU2F471MELB has an intermediate diameter (1.181" / 30.00 mm) and height (1.654" / 42.00 mm). Both parts retain Active status and full compliance. These substitutes require verification of available PCB space and lead hole positioning before implementation.

All substitute parts maintain the required 0.394" (10.00 mm) lead spacing, through-hole mounting configuration, and -25°C to 105°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can LGN2V471MELC30 be used as a direct replacement for LGU2F471MELC? A: Yes. LGN2V471MELC30 is a direct physical and functional replacement with identical case dimensions and lead spacing. The 350 V rating exceeds the original 315 V specification, providing additional voltage margin without circuit modification.

Q: What is the difference between upgrade and similar substitutes? A: Upgrade substitutes (LGN2V471MELC30, 400MXK470MEFCSN35X30, EKMS401VSN471MA30S) maintain identical physical dimensions to the main part and provide equal or higher voltage ratings. Similar substitutes (LGU2F471MELA, LGU2F471MELB) match electrical specifications but have different case diameters and heights, requiring PCB layout verification.

Q: Are the Rubycon and Chemi-Con parts compatible with Nichicon designs? A: Yes. 400MXK470MEFCSN35X30 (Rubycon) and EKMS401VSN471MA30S (Chemi-Con) share identical physical dimensions, lead spacing, and electrical specifications with the Nichicon main part. All parts are Active status with appropriate compliance certifications.

Q: Can LGU2F471MELA or LGU2F471MELB be used if PCB space is limited? A: LGU2F471MELB offers a compromise with intermediate dimensions (1.181" diameter, 1.654" height) compared to the main part (1.378" diameter, 1.260" height). LGU2F471MELA is more compact in diameter but taller. Both require PCB layout verification before selection.

Q: Do all substitute parts meet the same compliance requirements? A: All substitute parts maintain Active product status. Nichicon parts (LGN2V471MELC30, LGU2F471MELA, LGU2F471MELB) are ROHS3 Compliant. Rubycon (400MXK470MEFCSN35X30) and Chemi-Con (EKMS401VSN471MA30S) are RoHS Compliant. All parts are REACH Unaffected.

Q: What is the lead spacing requirement for all parts? A: All parts, including the main part and all substitutes, maintain 0.394" (10.00 mm) lead spacing, ensuring compatibility with standard through-hole PCB layouts designed for the LGU2F471MELC.
