Substitute Part Grouping Explanation

Substitution eligibility is determined by strict parameter matching across electrical and mechanical specifications. All substitute parts must meet the following core criteria:

Mandatory Matching Parameters:

Capacitance: 560 µF
Voltage Rating: 250 V
Tolerance: ±20%
Operating Temperature Range: -40°C to 85°C
Package Type: Radial, Can - Snap-In
Mounting Type: Through Hole
Lead Spacing: 0.394" (10.00 mm)
Polarization: Polar

Acceptable Variation Parameters:

ESR: Equivalent or lower values acceptable
Lifetime @ 85°C: Equal or greater duration acceptable
Case Diameter: Mechanical fit within application constraints
Height: Mechanical fit within application constraints
Ripple Current: Equal or greater capacity acceptable

Substitute parts are categorized as "Direct" when all parameters match within tolerance, and "Similar" when mechanical dimensions (diameter or height) differ while maintaining electrical equivalence.

Engineering Selection Recommendations

Direct Substitutes (Preferred for Electrical Equivalence):

SLPX561M250C5P3 (CDE) provides the closest electrical match to ECO-S2EP561CX with identical 3000-hour lifetime at 85°C, matching ESR specification at 355 mOhm, and ROHS3 compliance. Height reduction from 40.00 mm to 35.00 mm requires PCB layout verification.

250USG560MEFCSN25X30 (Rubycon) maintains 3000-hour lifetime with ROHS3 compliance and reduced height (32.00 mm), suitable for space-constrained applications. ESR data not provided; electrical performance verification recommended.

LLS2E561MELA (Nichicon) offers 3000-hour lifetime with ROHS3 compliance and intermediate height (35.00 mm), providing mechanical flexibility.

Conditional Substitutes (Reduced Lifetime):

380LQ561M250J022 (CDE) and 380LQ561M250H042 (CDE) provide 2000-hour lifetime at 85°C, representing 33% reduction from original specification. Acceptable only where application duty cycle permits reduced operational life.

LPX561M250C7P3 (CDE) and LPX561M250A9P3 (CDE) provide 1000-hour lifetime, suitable only for applications with minimal thermal stress or short operational duration.

Similar Substitutes (Mechanical Variation):

380LQ561M250K012 (CDE) features larger diameter (30.00 mm) and reduced height (27.00 mm), requiring PCB footprint redesign. Maintains 2000-hour lifetime and ROHS3 compliance.

380LX561M250A012 (CDE) features largest diameter (35.00 mm) and reduced height (27.00 mm), with matching 3000-hour lifetime and 326 mOhm ESR. Requires significant PCB layout modification.

LPX561M250A9P3 (CDE) features smallest diameter (22.00 mm) and maximum height (50.00 mm), with 1000-hour lifetime limitation.

Compliance Considerations:

All active substitute parts carry ROHS3 compliance except 250USG560MEFC25X30 (RoHS non-compliant). Selection must align with end-product regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can ECO-S2EP561CX be directly replaced with any active substitute?

A: Direct replacement depends on mechanical constraints. SLPX561M250C5P3, 250USG560MEFCSN25X30, and LLS2E561MELA maintain electrical equivalence with height variations. Verify PCB clearance and mounting hole alignment before substitution.

Q: What is the impact of reduced lifetime specifications?

A: Parts rated for 2000 hours (380LQ series) or 1000 hours (LPX series) have proportionally reduced operational life at 85°C. Selection must account for application thermal environment and expected service duration. Higher ambient temperatures accelerate capacitor aging beyond rated specifications.

Q: Are all substitutes ROHS3 compliant?

A: No. 250USG560MEFC25X30 is RoHS non-compliant. All CDE and Nichicon alternatives carry ROHS3 compliance. Verify compliance requirements for your end application before selection.

Q: How do case diameter and height variations affect PCB design?

A: Mechanical dimensions determine mounting footprint and clearance requirements. Larger diameter parts (30.00 mm, 35.00 mm) require wider PCB spacing. Height variations (27.00 mm to 50.00 mm) affect component stacking and enclosure fit. Verify mechanical fit within your specific application before committing to substitution.

Q: What is the significance of ESR differences?

A: ESR affects ripple current handling and thermal performance. Lower ESR (326 mOhm) provides better high-frequency performance. Higher ESR (355 mOhm) increases heat generation under ripple current stress. For applications with significant AC ripple, prefer lower ESR specifications.

Q: Can I substitute based on capacitance and voltage alone?

A: No. Lifetime, ESR, case dimensions, and compliance certifications are equally critical. Substitution based on electrical parameters alone may result in premature failure or regulatory non-compliance. All parameters listed in this reference must be evaluated for your specific application.
