LGN2D561MELY40 Equivalent & Substitute Parts

Part Overview

The LGN2D561MELY40 is a 560 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 and ROHS3 compliant.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design flexibility is required for PCB layout optimization, or when alternative manufacturers' components meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

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

Capacitance: 560 µF (exact match required)
Voltage Rating: 200 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Mounting Type: Through Hole (exact match required)
Operating Temperature Range: -40°C ~ 105°C (exact match required)

All substitute parts listed meet these core electrical and mechanical criteria. Variations in physical dimensions (diameter and height), ripple current ratings, and series designation do not prevent substitution when the above parameters are identical. Parts with 3000-hour lifetime ratings at 105°C are directly equivalent to the main part. Parts with 2000-hour lifetime ratings represent a reduced-reliability alternative suitable only when application requirements permit lower operational longevity.

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications.

For direct electrical equivalence with identical operational longevity, select from the following Nichicon parts: LGN2D561MELZ35, LGU2D561MELA, LGU2D561MELB, LGU2D561MELY, LGU2D561MELZ, or LGW2D561MELA30. These parts maintain the 3000-hour lifetime rating at 105°C.

For cross-manufacturer substitution, the Cornell Dubilier Electronics parts 381LR561M200H042 and 381LX561M200H042 provide equivalent electrical performance with identical voltage, capacitance, and lifetime specifications.

Parts LGG2D561MELA25 and LGG2D561MELZ30 offer reduced operational longevity at 2000 hours at 105°C and are suitable only when application duty cycles and reliability requirements permit this reduced lifetime.

Physical dimension variations across substitute parts require PCB layout verification to ensure mechanical fit within the allocated component footprint space.

Frequently Asked Questions (FAQ)

Q: Can LGU2D561MELY be used as a direct replacement for LGN2D561MELY40?

A: Yes. Both parts share identical electrical specifications: 560 µF capacitance, 200 V voltage rating, ±20% tolerance, 3000-hour lifetime at 105°C, and 10.00 mm lead spacing. The primary difference is physical dimension (LGU2D561MELY: 20.00 mm diameter × 50.00 mm height versus LGN2D561MELY40: 20.00 mm diameter × 42.00 mm height). PCB layout space must accommodate the increased height.

Q: Are the Nichicon LGG series parts (2000-hour lifetime) acceptable substitutes?

A: LGG2D561MELA25 and LGG2D561MELZ30 meet all electrical and mechanical criteria but operate at reduced longevity (2000 hours at 105°C versus 3000 hours). These parts are acceptable only when application requirements permit lower operational lifetime or when cost reduction justifies the trade-off.

Q: Can Cornell Dubilier Electronics 381LR561M200H042 replace the Nichicon LGN2D561MELY40?

A: Yes. Both parts are electrically equivalent with 560 µF, 200 V, ±20% tolerance, and 3000-hour lifetime at 105°C. The 381LR part has 22.00 mm diameter and 42.00 mm height, matching the LGN2D561MELY40 height but with different diameter. PCB layout verification is required.

Q: What is the significance of different series designations (LGN, LGU, LGG, LGW)?

A: Series designations indicate different product lines within Nichicon's aluminum electrolytic capacitor portfolio. Within the constraints of identical electrical specifications and lead spacing, different series parts are mechanically interchangeable. Series differences reflect internal design variations and ripple current handling capabilities but do not affect substitution eligibility when core parameters match.

Q: Does the LGW2D561MELA30 offer any performance advantage over the LGN2D561MELY40?

A: LGW2D561MELA30 maintains identical electrical specifications but exhibits higher ripple current ratings (2.3 A @ 120 Hz and 3.45 A @ 50 kHz versus 1.6 A @ 120 Hz and 2.4 A @ 50 kHz for the main part). This represents enhanced thermal performance capability. Physical dimensions differ (25.00 mm diameter × 30.00 mm height), requiring PCB layout verification.

Q: Are all listed parts suitable for the same operating temperature range?

A: Yes. All substitute parts operate across the identical temperature range of -40°C to 105°C, matching the LGN2D561MELY40 specification.
