LGN2D471MELY35 Equivalent & Substitute Parts

Part Overview

The LGN2D471MELY35 is a 470 µF, 200 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 is designed for general-purpose applications requiring high-voltage energy storage and filtering. The part is Active status and ROHS3 compliant.

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when design revisions require alternative form factors, or when performance specifications allow for compatible alternatives from the same or different manufacturers. Substitution must maintain electrical equivalence across capacitance, voltage rating, tolerance, and thermal lifetime specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the LGN2D471MELY35 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence: Capacitance value (470 µF), voltage rating (200 V), and tolerance (±20%) must match exactly
Thermal Specification: Lifetime rating of 3000 Hrs @ 105°C or greater
Operating Range: Temperature range must encompass -40°C to 105°C
Mechanical Compatibility: Through-hole mounting with radial, can-style snap-in package and 10.00mm lead spacing
Compliance: ROHS3 compliance required

Substitute parts are grouped into two categories:

Category A - Nichicon LGN/LGU/LGW Series (Same Manufacturer) These parts maintain identical electrical specifications and differ only in physical dimensions (diameter and height). All are Nichicon products with 3000 Hrs @ 105°C lifetime and ROHS3 compliance.

Category B - Cornell Dubilier Electronics (CDE) 381LQ/381LR Series (Alternative Manufacturer) These parts meet electrical specifications but may have different ESR characteristics and thermal lifetime ratings. CDE parts are ROHS3 compliant with MSL rating of 1 (Unlimited).

Engineering Selection Recommendations

Nichicon LGN/LGU/LGW Series Substitutes

All Nichicon alternatives (LGN2D471MELZ30, LGU2D471MELA, LGU2D471MELB, LGU2D471MELY, LGU2D471MELZ, LGW2D471MELA25, LGW2D471MELZ30) are direct electrical equivalents with identical 470 µF, 200 V, ±20% specifications and 3000 Hrs @ 105°C lifetime. These parts are ROHS3 compliant and suitable for direct substitution where physical dimensions permit. Selection among these alternatives depends on available PCB space and mounting hole layout compatibility.

Cornell Dubilier Electronics (CDE) 381LQ/381LR Series Substitutes

The 381LQ471M200H022 meets electrical specifications but has a reduced thermal lifetime of 2000 Hrs @ 105°C compared to the 3000 Hrs rating of the primary part. This part is suitable only for applications where the lower thermal rating is acceptable.

The 381LR471M200H032 and 381LR471M200J022 are full electrical equivalents with 3000 Hrs @ 105°C lifetime and ROHS3 compliance. These CDE parts are suitable for direct substitution where manufacturer diversity is required or Nichicon parts are unavailable. Physical dimensions differ; verify PCB layout compatibility before selection.

All substitute parts maintain the required -40°C to 105°C operating temperature range and through-hole radial snap-in package configuration with 10.00mm lead spacing.

Frequently Asked Questions (FAQ)

Q: Can I substitute LGU2D471MELA for LGN2D471MELY35 in my design?

A: Electrical substitution is valid. Both parts are 470 µF, 200 V, ±20% tolerance with 3000 Hrs @ 105°C lifetime and ROHS3 compliance. However, LGU2D471MELA has a diameter of 25.00mm and height of 30.00mm, while LGN2D471MELY35 is 20.00mm diameter and 37.00mm height. Verify that your PCB layout accommodates the different physical dimensions before substitution.

Q: What is the difference between Nichicon LGN, LGU, and LGW series?

A: All three series meet the same electrical specifications for this 470 µF, 200 V application. The series designation reflects internal design variations that result in different physical dimensions (diameter and height). Electrical performance and thermal ratings remain equivalent across series for this capacitance and voltage rating.

Q: Can I use 381LQ471M200H022 instead of the primary part?

A: Electrical substitution is possible for the 470 µF, 200 V, ±20% specification. However, the 381LQ part has a thermal lifetime of 2000 Hrs @ 105°C versus 3000 Hrs for the primary part. Use this substitute only if your application does not require the full 3000-hour thermal rating. The 381LR series alternatives provide the full 3000-hour rating.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the compliance status of the primary LGN2D471MELY35 part.

Q: What is the significance of lead spacing in substitution?

A: All listed parts maintain 10.00mm lead spacing, which is the standard for this capacitor category. This ensures PCB hole pattern compatibility. Verify lead spacing on any substitute part before installation.

Q: Can physical dimensions vary between substitutes?

A: Yes. Nichicon LGN, LGU, and LGW series parts and CDE 381LR alternatives have different diameter and height dimensions while maintaining identical electrical specifications and thermal ratings. Verify that your PCB layout and mechanical enclosure accommodate the substitute part's physical dimensions before selection.
