Substitute Part Grouping Explanation

Substitute parts for the LGN2C561MELY35 are qualified based on the following criteria:

Electrical Equivalence: Capacitance value (560 µF), voltage rating (160 V), tolerance (±20%), and lifetime specification (3000 Hrs @ 105°C) must be identical
Mechanical Compatibility: Lead spacing (10.00 mm) and mounting type (Through Hole, Radial, Can - Snap-In) must match
Thermal Performance: Operating temperature range (-40°C ~ 105°C) and polarization (Polar) must be maintained
Compliance: RoHS3 compliance and REACH Unaffected status required

The identified substitutes are LGN2C561MELZ30 and LGU2C561MELA, both manufactured by Nichicon. These parts maintain identical electrical specifications and mounting compatibility while varying in physical dimensions and ripple current ratings.

Engineering Selection Recommendations

All three parts—LGN2C561MELY35, LGN2C561MELZ30, and LGU2C561MELA—maintain Active product status and full compliance with ROHS3 and REACH requirements. Selection between these parts is determined by physical space constraints and ripple current capacity requirements:

LGN2C561MELY35: Smallest diameter (20.00 mm) and tallest height (37.00 mm). Suitable for applications with vertical space availability and standard ripple current demands (1.5 A @ 120 Hz, 2.25 A @ 50 kHz).
LGN2C561MELZ30: Intermediate diameter (22.00 mm) and reduced height (32.00 mm). Maintains identical ripple current specifications as the main part while offering compact vertical profile.
LGU2C561MELA: Largest diameter (25.00 mm) and shortest height (30.00 mm). Provides enhanced ripple current capacity (1.67 A @ 120 Hz, 2.505 A @ 50 kHz) for applications requiring higher current handling with minimal vertical clearance.

Frequently Asked Questions (FAQ)

Q: Can LGN2C561MELZ30 be used as a direct replacement for LGN2C561MELY35?

A: Yes. Both parts share identical electrical specifications (560 µF, 160 V, ±20%, 3000 Hrs @ 105°C) and mechanical compatibility (10.00 mm lead spacing, Through Hole, Radial, Can - Snap-In). The primary difference is physical dimensions: LGN2C561MELZ30 has a smaller diameter (22.00 mm vs. 20.00 mm) and reduced height (32.00 mm vs. 37.00 mm). Verify PCB layout accommodates the dimensional change.

Q: What is the difference between LGU2C561MELA and the LGN series parts?

A: LGU2C561MELA belongs to the LGU series and maintains identical electrical specifications and lead spacing. The key differences are physical dimensions and ripple current ratings. LGU2C561MELA offers higher ripple current capacity (1.67 A @ 120 Hz, 2.505 A @ 50 kHz) compared to the LGN series (1.5 A @ 120 Hz, 2.25 A @ 50 kHz), with a larger diameter (25.00 mm) and shorter height (30.00 mm).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. LGN2C561MELY35, LGN2C561MELZ30, and LGU2C561MELA are all ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What determines whether a part can substitute for the LGN2C561MELY35?

A: Substitution is determined by matching capacitance (560 µF), voltage rating (160 V), tolerance (±20%), lifetime (3000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), lead spacing (10.00 mm), and mounting type (Through Hole, Radial, Can - Snap-In). Physical dimensions may vary provided PCB layout permits the change.

Q: Can I use a substitute part with higher ripple current rating?

A: Yes. LGU2C561MELA provides higher ripple current capacity and is electrically and mechanically compatible. Higher ripple current rating does not create compatibility issues; it indicates enhanced performance capability for the same electrical specifications.
