Nichicon LGU2P561MELB Equivalent & Substitute Parts

Part Overview

The Nichicon LGU2P561MELB is a 560 µF, 220 V aluminum electrolytic capacitor in radial, can snap-in package configuration. This component is rated for 3000 hours at 105°C and is designed for general-purpose applications requiring through-hole mounting. The part is Active status and ROHS3 compliant.

Substitute Part Grouping Explanation

Substitution eligibility for the LGU2P561MELB is determined by the following criteria:

Primary Electrical Parameters: Capacitance (560 µF), voltage rating (220 V), and tolerance (±20%) must match exactly. These parameters define the core electrical function.

Thermal & Reliability Parameters: Operating temperature range (-40°C ~ 105°C) and lifetime rating (3000 Hrs @ 105°C) establish performance boundaries. Parts with reduced lifetime (2000 Hrs @ 105°C) represent a lower reliability tier.

Mechanical Parameters: Lead spacing (10.00 mm), package type (Radial, Can - Snap-In), and mounting type (Through Hole) must be compatible with PCB design. Physical dimensions (diameter and height) may vary within the snap-in package family while maintaining electrical and mechanical compatibility.

Compliance Parameters: RoHS3 compliance and REACH unaffected status are mandatory for equivalent substitution.

Substitute parts are grouped into two categories: Direct equivalents (matching all parameters including lifetime) and similar alternatives (matching electrical and mechanical parameters with reduced lifetime or dimensional variations).

Engineering Selection Recommendations

Direct Equivalent (Preferred): LGN2P561MELB25 provides full electrical and thermal equivalence to LGU2P561MELB with identical 3000-hour lifetime at 105°C and 220 V rating. Physical height is reduced (27.00 mm vs. 30.00 mm), which may provide PCB layout advantages. All parts maintain ROHS3 compliance and Active product status.

Thermal Equivalent with Dimensional Variation: LGN2P561MELA35 and LGN2P561MELZ40 maintain the 3000-hour lifetime specification and 220 V rating. These parts accommodate different PCB footprint requirements through diameter and height variations while preserving electrical performance.

Reduced Lifetime Alternative: LGG2P561MELA30 and LGG2P561MELZ35 provide electrical equivalence (560 µF, 220 V, ±20% tolerance) with reduced lifetime rating (2000 Hrs @ 105°C). These parts are suitable for applications with lower thermal stress or shorter service life requirements.

Higher Voltage Rating: LGU2E561MELB operates at 250 V with 560 µF capacitance and 3000-hour lifetime. This part is electrically compatible in circuits designed for 220 V operation and provides additional voltage margin. Mechanical dimensions differ (30.00 mm diameter, 35.00 mm height).

All substitute parts are Active status and ROHS3 compliant, meeting regulatory requirements equivalent to the primary part.

Frequently Asked Questions (FAQ)

Q: Can LGN2P561MELB25 replace LGU2P561MELB directly? A: Yes. Both parts share identical electrical specifications (560 µF, 220 V, ±20%, 3000 Hrs @ 105°C) and lead spacing (10.00 mm). The height difference (27.00 mm vs. 30.00 mm) is within the snap-in package family and does not affect electrical compatibility. PCB layout must accommodate the reduced height.

Q: What is the difference between LGN and LGG series parts? A: The LGN series maintains 3000-hour lifetime at 105°C, while the LGG series is rated for 2000 hours at 105°C. Both series share identical electrical parameters (560 µF, 220 V) and package type. Selection depends on application thermal stress and required service life.

Q: Can LGU2E561MELB (250 V) be used instead of LGU2P561MELB (220 V)? A: Yes, from an electrical standpoint. The 250 V rating provides additional voltage margin in 220 V circuits. However, physical dimensions differ (35.00 mm height vs. 30.00 mm), requiring PCB layout verification. This substitution is suitable when space permits and higher voltage rating is acceptable.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory profile of LGU2P561MELB.

Q: What determines if a part can substitute for LGU2P561MELB? A: Substitution requires matching capacitance (560 µF), voltage rating (220 V), tolerance (±20%), lead spacing (10.00 mm), package type (Radial, Can - Snap-In), and mounting type (Through Hole). Lifetime rating, physical dimensions, and ripple current may vary within acceptable engineering parameters. All parts must maintain ROHS3 compliance.

Q: Can I use a part with lower ripple current rating? A: Ripple current capacity must meet or exceed circuit requirements. Parts with lower ripple current ratings (LGG series: 1.45 A @ 120 Hz vs. LGU/LGN series: 1.7-1.8 A @ 120 Hz) are suitable only if circuit ripple current demand is within the lower specification.
