ECO-S2DA561DA Equivalent & Substitute Parts

Part Overview

The ECO-S2DA561DA is a 560 µF, 200 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Panasonic Electronic Components. This component is classified as obsolete, making direct replacement necessary for ongoing production and maintenance applications. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 3000 hours at 105°C, serving general-purpose applications requiring stable capacitance and low equivalent series resistance.

Substitute Part Grouping Explanation

Substitution for the ECO-S2DA561DA is determined by strict equivalence across the following parameters:

Capacitance value: 560 µF (exact match required)
Voltage rating: 200 V (minimum, equal or higher acceptable for direct substitutes)
Package configuration: Radial, Can - Snap-In (mechanical and electrical interface compatibility)
Lead spacing: 0.394" (10.00 mm) (PCB footprint compatibility)
Mounting type: Through Hole (assembly process compatibility)
Operating temperature range: -40°C to 105°C (functional envelope)
Polarization: Polar (circuit application requirement)

Direct substitutes maintain all parameters at 200 V rating. Upgrade substitutes increase voltage rating to 250 V while maintaining all other specifications, providing enhanced voltage margin for the same physical footprint and electrical interface.

Engineering Selection Recommendations

All substitute parts listed maintain the core electrical specifications of 560 µF capacitance, ±20% tolerance, and through-hole radial snap-in package configuration required for direct PCB compatibility with the ECO-S2DA561DA.

Direct substitutes at 200 V rating include parts from Cornell Dubilier (381LX561M200K012), KEMET (ALC80A561CB200, ALC80D561CB200), EPCOS-TDK (B43254C2567M), Nichicon (LGR2D561MELB30, LGU2D561MELB), and Cornell Dubilier (SLP561M200E1P3). All direct substitutes are active products with ROHS3 compliance, addressing the obsolescence of the original part.

Upgrade substitutes at 250 V rating (381LR561M250K022, B43254G2567M, B43508G2567M2) provide increased voltage margin while maintaining identical capacitance, tolerance, and package footprint. These upgrades are suitable for applications where higher voltage headroom is beneficial.

Height variations exist among substitutes. Parts with 1.063" (27.00 mm) maximum seated height (381LX561M200K012, B43254C2567M) and 0.984" (25.00 mm) maximum seated height (LGU2D561MELB, SLP561M200E1P3) require PCB clearance verification. Parts matching the original 1.260" (32.00 mm) height (ALC80A561CB200, ALC80D561CB200, LGR2D561MELB30, and all 250 V upgrades) provide direct mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use a 250 V rated substitute in place of the 200 V original?

A: Yes. The 250 V upgrade substitutes (381LR561M250K022, B43254G2567M, B43508G2567M2) maintain identical capacitance, tolerance, package type, and lead spacing. Higher voltage rating provides additional safety margin and does not degrade circuit performance in 200 V applications.

Q: What is the significance of height differences among substitutes?

A: Height variations affect PCB clearance and component density. The original ECO-S2DA561DA has a maximum seated height of 1.260" (32.00 mm). Substitutes with shorter heights (1.063" or 0.984") require verification that the PCB layout accommodates the original height specification. Substitutes matching the original 1.260" height provide direct mechanical compatibility without layout modification.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, addressing the non-compliance status of the obsolete ECO-S2DA561DA. This compliance is mandatory for applications subject to RoHS regulations.

Q: How do ESR values affect substitute selection?

A: ESR (Equivalent Series Resistance) values are provided for certain parts. The original part specifies 296 mOhm @ 120 Hz. Substitutes with comparable or lower ESR values maintain equivalent electrical performance. Parts with unspecified ESR values are functionally equivalent based on matching capacitance, voltage, tolerance, and package specifications.

Q: What is the difference between direct substitutes and upgrade substitutes?

A: Direct substitutes maintain the 200 V voltage rating of the original part. Upgrade substitutes increase the voltage rating to 250 V while preserving all other electrical and mechanical parameters. Both categories are electrically and mechanically compatible with the original application.

Q: Can I mix substitute parts from different manufacturers in the same circuit?

A: Yes. All substitute parts meet the same electrical specifications (560 µF, ±20%, 200 V or 250 V, through-hole radial snap-in package). Mixing manufacturers is acceptable provided the PCB footprint and height clearance accommodate all selected parts.
