Engineering Selection Recommendations

For Direct Replacement (Mechanical and Electrical Compatibility):

Select from active-status parts maintaining 400 V rating and 560 µF capacitance. The 380LX561M400A452 provides matching ESR characteristics (326 mOhm @ 120Hz) with identical lifetime rating (3000 Hrs @ 85°C) and is currently in active production status. The B43501B9567M000 offers superior ESR performance (120 mOhm @ 100Hz) and extended lifetime (10000 Hrs @ 85°C), suitable for applications requiring lower impedance or higher reliability margins.

For Space-Constrained Applications:

The SLPX561M400H7P3 and LLS2G561MELC provide compact form factors with reduced height (1.575" and 1.654" respectively) while maintaining full electrical compatibility. Both are ROHS3 compliant and in active production.

For Enhanced Thermal Performance:

The ETXH401VSN561MA50S extends operating temperature to 105°C with 10000-hour lifetime at that temperature, maintaining the original 400 V rating and snap-in package. The LGUW6561MELC provides 420 V rating with 105°C operating capability, offering additional voltage margin for applications with transient overvoltage conditions.

Compliance Considerations:

All substitute parts listed carry ROHS3 compliance or RoHS compliance status. The ECO-S2GP561EA is REACH Affected; all active substitutes are REACH Unaffected, eliminating regulatory documentation requirements for new designs.

Frequently Asked Questions (FAQ)

Q: Can I use a 420 V rated capacitor in place of the 400 V ECO-S2GP561EA?

A: Yes. The LGUW6561MELC (420 V, 560 µF) is mechanically and electrically compatible. Higher voltage ratings provide additional safety margin and do not degrade circuit performance in 400 V applications.

Q: What is the difference between the 380LX561M400A052 and 380LX561M400A452?

A: Both are 560 µF, 400 V Cornell Dubilier parts with 3000-hour lifetime at 85°C. The primary difference is height: 2.047" (52.00 mm) versus 1.850" (47.00 mm). The 380LX561M400A452 matches the ESR specification (326 mOhm @ 120Hz) of the original part.

Q: Why does the B43501B9567M000 have lower ESR than the original part?

A: Lower ESR (120 mOhm @ 100Hz versus 326 mOhm @ 120Hz) reflects superior internal construction and materials in the EPCOS design. This reduces heat generation and improves ripple current handling, providing performance enhancement without circuit modification.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All listed substitutes maintain the radial, can snap-in package with 0.394" (10.00 mm) lead spacing and 1.378" (35.00 mm) case diameter. Height variations exist (1.457" to 2.047") due to different internal construction; verify PCB clearance for your specific application.

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

A: Direct equivalents maintain all original electrical and mechanical specifications. Upgrade equivalents enhance one or more parameters—such as lifetime, temperature range, or voltage rating—while preserving mechanical compatibility and core capacitance/voltage values.

Q: Can I substitute the 382LX561M400A052 (4-lead version) for the standard 2-lead ECO-S2GP561EA?

A: The 382LX561M400A052 maintains identical electrical specifications and snap-in package but features 4-lead construction. Verify your PCB layout supports 4-lead configuration before selection.
