Substitute Part Grouping Explanation

Substitution of the ECO-S1EP223DA is determined by strict equivalence in the following parameters:

Capacitance: 22000 µF (exact match required)
Voltage Rating: 25 V (exact match required)
Tolerance: ±20% (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Mounting Type: Through Hole (exact match required)
Operating Temperature Range: -40°C to 85°C (exact match required)
Lifetime @ 85°C: 3000 Hrs minimum (equal or greater acceptable)

Substitute parts are classified into two categories:

Direct Substitutes: Parts meeting all key parameters with identical or superior electrical characteristics and current product status.

Similar Substitutes: Parts meeting all key parameters but with variations in case diameter or height that may require mechanical verification for board-level compatibility.

Engineering Selection Recommendations

Direct Substitutes (Identical Footprint - 30 mm Diameter, 40 mm Height):

SLPX223M025E7P3 (Cornell Dubilier Electronics) is the primary direct substitute. It maintains the original case diameter and height, requires no board-level modifications, and offers superior ESR performance at 27 mOhm compared to the original 29 mOhm. Product status is active with ROHS3 compliance.

Acceptable Substitutes (Mechanical Verification Required):

25USG22000MEFCSN30X35 (Rubycon) maintains the 30 mm case diameter but reduces height to 37 mm. This part is suitable for applications where vertical clearance permits the reduced height. ROHS3 compliant and active status.

380LX223M025K042 (Cornell Dubilier Electronics) maintains the 30 mm case diameter but increases height to 42 mm. This part requires verification of available vertical space on the PCB. ROHS3 compliant and active status.

Similar Substitutes (Dimensional Variation - Requires Board-Level Assessment):

380LX223M025J052 (Cornell Dubilier Electronics) reduces case diameter to 25 mm but increases height to 52 mm. Suitable only for applications where the reduced footprint diameter is acceptable and vertical clearance is available.

SLPX223M025C9P3 (Cornell Dubilier Electronics) reduces case diameter to 25 mm and height to 50 mm. Requires verification of both horizontal and vertical space constraints.

SLPX223M025H5P3 (Cornell Dubilier Electronics) increases case diameter to 35 mm but reduces height to 35 mm. Suitable for applications where horizontal space is available and vertical clearance is limited.

Not Recommended:

B41231A5229M000 (EPCOS - TDK Electronics) has a reduced lifetime rating of 2000 hours at 85°C compared to the required 3000 hours. This part does not meet the minimum lifetime specification.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different case diameter?

A: Substitutes with different case diameters (25 mm or 35 mm versus the original 30 mm) require mechanical verification. The PCB footprint, mounting holes, and surrounding component placement must accommodate the new diameter. Consult your PCB layout documentation before selection.

Q: What is the impact of ESR differences between substitute parts?

A: ESR (Equivalent Series Resistance) affects ripple current handling and heat generation. The original part specifies 29 mOhm at 120 Hz. Substitutes with lower ESR (27 mOhm) provide improved performance. Substitutes with higher ESR (30 mOhm) remain within acceptable tolerance for general purpose applications but may generate slightly more heat under high ripple current conditions.

Q: Why is B41231A5229M000 not recommended?

A: This part specifies a lifetime of 2000 hours at 85°C, which is below the original specification of 3000 hours. For applications requiring the full rated lifetime, this part does not meet the minimum requirement.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed are ROHS3 compliant. The original ECO-S1EP223DA does not specify RoHS status due to its obsolete status.

Q: What is the difference between "Direct Substitutes" and "Similar Substitutes"?

A: Direct substitutes maintain identical case diameter and height, requiring no board-level modifications. Similar substitutes have dimensional variations that may require PCB layout verification or mechanical redesign to accommodate the new form factor.

Q: Can I use a substitute with reduced height if my application has vertical space constraints?

A: Yes, if your application has limited vertical clearance, parts with reduced height (such as 25USG22000MEFCSN30X35 at 37 mm or SLPX223M025H5P3 at 35 mm) are suitable alternatives. Verify that the reduced height does not conflict with other board components or enclosure constraints.
