LGU2A561MELZ Equivalent & Substitute Parts

Part Overview

The LGU2A561MELZ is a 560 µF, 100 V aluminum electrolytic capacitor manufactured by Nichicon in a radial, can snap-in package. This component is designed for general-purpose applications requiring stable capacitance performance across extended operating temperatures from -40°C to 105°C, with a rated lifetime of 3000 hours at 105°C. The part is currently active in production and ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

The 381LX561M100H012 manufactured by Cornell Dubilier Electronics (CDE) qualifies as a parametric equivalent based on the following critical substitution criteria:

Electrical Parameters: Capacitance value (560 µF), tolerance (±20%), and rated voltage (100 V) are identical. Thermal performance matches with 3000 hours lifetime at 105°C and identical operating temperature range (-40°C ~ 105°C).

Mechanical Parameters: Lead spacing (0.394" / 10.00mm), can diameter (0.866" / 22.00mm), and seated height (1.063" / 27.00mm) are identical. Both components use radial, can snap-in packaging with through-hole mounting.

Compliance: Both parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for equivalent substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the LGU2A561MELZ and 381LX561M100H012 are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on availability and supply chain requirements. The 381LX561M100H012 demonstrates slightly higher ripple current capability at low frequency (1.1 A @ 120 Hz versus 1.07 A), providing marginal performance headroom in applications with ripple current constraints. Both components meet identical electrical and mechanical specifications for direct substitution in through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can the 381LX561M100H012 be used as a direct replacement for the LGU2A561MELZ?

A: Yes. Both components share identical capacitance (560 µF), voltage rating (100 V), tolerance (±20%), thermal lifetime (3000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), and mechanical dimensions. Lead spacing, can diameter, and seated height are identical. Both use radial, can snap-in packaging with through-hole mounting.

Q: Are there any differences in ripple current performance?

A: The 381LX561M100H012 specifies 1.1 A ripple current at 120 Hz compared to 1.07 A for the LGU2A561MELZ. This represents a minor performance difference that does not affect substitution eligibility for general-purpose applications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the LGU2A561MELZ and 381LX561M100H012 are ROHS3 compliant and REACH unaffected, meeting identical regulatory standards.

Q: What is the snap-in package configuration?

A: Both components use a radial, can snap-in package with a 0.394" (10.00mm) lead spacing, 0.866" (22.00mm) can diameter, and 1.063" (27.00mm) maximum seated height. This configuration allows direct mounting to PCBs with snap-in terminal connections.

Q: Are there any temperature or lifetime considerations for substitution?

A: No. Both parts operate across the identical temperature range (-40°C ~ 105°C) and share the same thermal lifetime rating of 3000 hours at 105°C, ensuring equivalent performance in temperature-dependent applications.
