LGU2D561MELZ Equivalent & Substitute Parts

Part Overview

The LGU2D561MELZ is a 560 µF, 200 V aluminum electrolytic capacitor manufactured by Nichicon in the LGU series. This radial, can-style snap-in component is rated for 3000 hours at 105°C and is designed for general-purpose applications requiring stable capacitance and ripple current handling across low and high frequency ranges. The part is ROHS3 compliant and currently in active production status with 1152 units in stock.

Equivalent and substitute parts are identified based on matching electrical specifications (capacitance, voltage rating, tolerance, and lifetime rating) and mechanical compatibility (lead spacing, mounting type, and package style). Alternative models from both Nichicon and Cornell Dubilier Electronics are available to support procurement flexibility, inventory optimization, and design continuity.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence in the following core parameters:

Electrical Match: Capacitance (560 µF), voltage rating (200 V), and tolerance (±20%) must be identical
Lifetime Rating: Parts rated for 3000 Hrs @ 105°C are direct equivalents; parts rated for 2000 Hrs @ 105°C are similar substitutes with reduced thermal endurance
Mechanical Compatibility: Lead spacing (10.00 mm), mounting type (through hole), and package style (radial, can - snap-in) must match
Polarization: All parts are polar aluminum electrolytic capacitors
Compliance: All parts maintain ROHS3 compliance and REACH unaffected status

Engineering Selection Recommendations

All listed substitute parts maintain active production status and ROHS3 compliance, ensuring regulatory continuity and long-term availability. Selection between direct equivalents should be based on:

For PCB space constraints: LGG2D561MELA25 and LGG2D561MELZ30 offer the most compact form factors, though with reduced 2000-hour lifetime rating. LGU2D561MELB provides a low-profile alternative (0.984" diameter, 0.984" height) while maintaining 3000-hour rating.

For thermal endurance applications: LGU2D561MELZ, LGN2D561MELZ35, LGU2D561MELA, LGU2D561MELB, LGU2D561MELY, LGW2D561MELA30, 381LR561M200H042, and 381LX561M200H042 all provide 3000-hour lifetime at 105°C.

For ripple current performance: LGW2D561MELA30 and 381LR561M200H042 deliver higher ripple current capacity (2.3 A and 2.14 A at 120 Hz respectively) compared to the base LGU2D561MELZ (1.67 A at 120 Hz).

For cross-manufacturer sourcing: 381LR561M200H042 and 381LX561M200H042 from Cornell Dubilier Electronics provide alternative supply chains while maintaining identical electrical specifications and lead spacing.

Frequently Asked Questions (FAQ)

Q: Can LGG series parts (2000 Hrs @ 105°C) replace LGU2D561MELZ (3000 Hrs @ 105°C)?

A: LGG2D561MELA25 and LGG2D561MELZ30 are electrically and mechanically compatible but have a reduced thermal lifetime rating. They are suitable for applications where the design does not require the full 3000-hour endurance at 105°C. Verify application thermal requirements before substitution.

Q: Are dimensional differences between substitute parts critical?

A: Yes. While all parts share 10.00 mm lead spacing and through-hole mounting, physical dimensions (diameter and height) vary significantly. Verify PCB layout, component clearances, and thermal management requirements before selecting a substitute with different dimensions.

Q: Can I use 381LR561M200H042 or 381LX561M200H042 as direct replacements?

A: Yes. Both Cornell Dubilier parts match the electrical specifications (560 µF, 200 V, ±20%, 3000 Hrs @ 105°C) and mechanical compatibility (10.00 mm lead spacing, radial snap-in package). They provide alternative sourcing from a different manufacturer while maintaining functional equivalence.

Q: What is the difference between LGU2D561MELY and LGU2D561MELZ?

A: Both are Nichicon LGU series parts with identical electrical ratings (560 µF, 200 V, 3000 Hrs @ 105°C). The primary difference is physical dimension: LGU2D561MELY has a smaller diameter (0.787") but greater height (1.969"), while LGU2D561MELZ has a larger diameter (0.866") and moderate height (1.575"). Select based on available PCB space.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original LGU2D561MELZ.

Q: Which substitute offers the best ripple current performance?

A: LGW2D561MELA30 provides the highest ripple current capacity at 2.3 A @ 120 Hz and 3.45 A @ 50 kHz, making it suitable for high-ripple-current applications. 381LR561M200H042 offers 2.14 A @ 120 Hz. Standard LGU and LGN series parts range from 1.48 A to 1.67 A @ 120 Hz.
