Key Parameters

Substitute Part Grouping Explanation

Substitution for the ECO-S2AA561BA is determined by strict equivalence across the following parameters: capacitance value (560 µF), voltage rating (100 V), tolerance (±20%), physical dimensions (0.866" diameter, 1.063" height, 10.00mm lead spacing), package type (radial, can snap-in), mounting method (through hole), and operating temperature range (-40°C to 105°C). All substitute parts listed maintain these core electrical and mechanical specifications, ensuring direct compatibility in circuit applications without modification to PCB layouts or component footprints.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—LGY2A561MELZ25, 381LX561M100H012, and LGU2A561MELZ—are active products with current manufacturing status, addressing the obsolescence of the ECO-S2AA561BA. The LGY2A561MELZ25 offers extended lifetime rating of 5000 hours at 105°C compared to the original 3000 hours, providing improved reliability for long-term applications. Both Nichicon parts (LGY2A561MELZ25 and LGU2A561MELZ) and the Cornell Dubilier part (381LX561M100H012) carry ROHS3 compliance, meeting modern environmental and regulatory requirements. Selection between these substitutes depends on application-specific requirements for component lifetime and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can LGY2A561MELZ25, 381LX561M100H012, and LGU2A561MELZ be used interchangeably with ECO-S2AA561BA?

A: Yes. All substitute parts maintain identical capacitance (560 µF), voltage rating (100 V), tolerance (±20%), physical dimensions, lead spacing (10.00mm), and mounting configuration (through-hole, radial snap-in). Direct substitution is possible without PCB modification.

Q: What is the primary difference between the substitute parts?

A: The LGY2A561MELZ25 provides 5000 hours lifetime at 105°C versus 3000 hours for the other substitutes. The 381LX561M100H012 and LGU2A561MELZ are parametric equivalents with matching 3000-hour ratings. All three are active products with ROHS3 compliance.

Q: Are there any ripple current differences between substitutes?

A: Ripple current specifications at 120 Hz are 1.1 A for ECO-S2AA561BA, LGY2A561MELZ25, and 381LX561M100H012, and 1.07 A for LGU2A561MELZ. These minor variations remain within acceptable tolerance for general-purpose applications.

Q: What compliance certifications apply to the substitute parts?

A: All substitute parts are ROHS3 compliant and carry REACH unaffected or affected status as specified. The original ECO-S2AA561BA is REACH affected. Verify compliance requirements for your specific application and regulatory jurisdiction.

Q: Can I use these substitutes in new designs or only for replacement applications?

A: These parts are suitable for both new designs and replacement applications. The active product status of all substitutes ensures long-term availability and supply chain stability for ongoing production.
