LGN2P471MELY45 Equivalent & Substitute Parts

Part Overview

The LGN2P471MELY45 is a 470 µF, 220 V aluminum electrolytic capacitor manufactured by Nichicon in the LGN series. This radial, can-style snap-in capacitor is rated for 3000 hours at 105°C and operates across a temperature range of -40°C to 105°C. The part is currently active in production with ROHS3 compliance and REACH unaffected status. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when alternative mechanical configurations are required for specific board layouts.

Substitute Part Grouping Explanation

Substitution for the LGN2P471MELY45 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence: Capacitance (470 µF), voltage rating (220 V), and tolerance (±20%) must be identical
Thermal Equivalence: Lifetime rating (3000 Hrs @ 105°C) and operating temperature range (-40°C ~ 105°C) must match
Mechanical Compatibility: Package type (Radial, Can - Snap-In), mounting type (Through Hole), and lead spacing (10.00 mm) must be identical
Compliance Equivalence: RoHS3 compliance and REACH unaffected status must be maintained

The substitute parts LGU2P471MELA and LGU2P471MELB meet all electrical, thermal, and compliance requirements. These parts differ only in physical dimensions (can diameter and height), which do not affect electrical performance or core functionality but may impact board layout considerations.

Engineering Selection Recommendations

All three parts—LGN2P471MELY45, LGU2P471MELA, and LGU2P471MELB—are electrically and thermally equivalent and maintain active production status with full ROHS3 compliance and REACH unaffected certification. Selection between these parts is determined by physical space constraints on the printed circuit board.

The LGN2P471MELY45 features a compact 20.00 mm diameter can with maximum height of 47.00 mm. The LGU2P471MELA provides a mid-range footprint with 25.00 mm diameter and 35.00 mm height. The LGU2P471MELB offers the largest diameter at 30.00 mm with the lowest profile at 25.00 mm height.

All parts share identical lead spacing (10.00 mm), enabling direct mechanical substitution when board layout permits the alternative can dimensions. Ripple current ratings are equivalent across all three parts, with negligible differences (1.45–1.48 A @ 120 Hz and 2.175–2.22 A @ 50 kHz) that do not affect circuit performance.

Frequently Asked Questions (FAQ)

Q: Can LGU2P471MELA or LGU2P471MELB be used as direct replacements for LGN2P471MELY45?

A: Yes, both LGU series parts are electrically and thermally equivalent. Direct substitution is possible provided the board layout accommodates the different can diameters and heights. Lead spacing remains constant at 10.00 mm across all three parts.

Q: What is the primary difference between these three parts?

A: The electrical and thermal specifications are identical. The only differences are physical dimensions: can diameter and seated height. These dimensional variations allow flexibility in board design and component placement.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts carry identical ROHS3 compliance and REACH unaffected status. Product status is active for all three manufacturers' parts.

Q: How do ripple current ratings compare?

A: Ripple current ratings are functionally equivalent. LGN2P471MELY45 rates 1.48 A @ 120 Hz and 2.22 A @ 50 kHz. Both LGU series parts rate 1.45 A @ 120 Hz and 2.175 A @ 50 kHz. These minor variations do not impact circuit design or performance.

Q: What should I consider when selecting between these parts?

A: Evaluate available board space. If the original LGN2P471MELY45 footprint (20.00 mm diameter, 47.00 mm height) does not fit, select LGU2P471MELA (25.00 mm diameter, 35.00 mm height) or LGU2P471MELB (30.00 mm diameter, 25.00 mm height) based on your layout constraints. All three are functionally interchangeable.

Q: Are these parts suitable for general-purpose applications?

A: Yes. All three parts are rated for general-purpose applications with 3000-hour lifetime at 105°C and -40°C to 105°C operating temperature range.
