Substitute Part Grouping Explanation

Substitution for the ECO-S1EP223CA is determined by strict equivalence across the following electrical and mechanical parameters:

Capacitance: 22000 µF (exact match required)
Voltage Rating: 25 V (exact match required)
Tolerance: ±20% (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Lead Spacing: 0.394" (10.00 mm) (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 (exact match required)

All substitute parts listed below meet these criteria. Variations in ESR, ripple current ratings, and physical dimensions (diameter and height) are permitted within the snap-in package family, as these do not affect electrical equivalence or functional interchangeability in the specified application.

Engineering Selection Recommendations

All listed substitute parts are manufactured by Cornell Dubilier Electronics and carry active product status, ensuring long-term availability and supply chain continuity. The SLPX series parts (SLPX223M025C9P3, SLPX223M025E7P3, SLPX223M025H5P3) feature lower ESR values at 27 mOhm compared to the original 29 mOhm specification, providing improved performance characteristics. The 380LX series parts (380LX223M025J052, 380LX223M025K042) maintain ESR at 30 mOhm, within acceptable tolerance of the original specification.

All substitute parts are ROHS3 compliant and carry REACH unaffected status, meeting current regulatory requirements. Selection between available substitutes should be based on physical form factor requirements, as dimensional variations exist across the snap-in package family while maintaining electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can SLPX223M025C9P3 directly replace ECO-S1EP223CA in existing designs?

A: Yes. Both parts share identical electrical specifications (22000 µF, 25 V, ±20% tolerance, 3000 Hrs @ 85°C) and package type (Radial, Can - Snap-In with 0.394" lead spacing). The lower ESR of SLPX223M025C9P3 (27 mOhm vs. 29 mOhm) represents improved performance within the same functional class.

Q: What is the difference between SLPX and 380LX series substitutes?

A: Both series meet the electrical equivalence criteria for the ECO-S1EP223CA. The primary difference is ESR: SLPX series parts are rated at 27 mOhm, while 380LX series parts are rated at 30 mOhm. Physical dimensions vary between series and individual part numbers within each series. Verify PCB layout compatibility before selection.

Q: Are all listed substitutes available in the same packaging format?

A: All substitutes use Radial, Can - Snap-In package type with 0.394" (10.00 mm) lead spacing. However, physical dimensions (diameter and height) vary across part numbers. Confirm PCB footprint and mounting clearance requirements before final selection.

Q: Do the substitute parts meet the same compliance standards as the original?

A: All active substitute parts are ROHS3 compliant and REACH unaffected. The original ECO-S1EP223CA is REACH affected. Substitute parts provide improved regulatory compliance for new designs and production runs.

Q: What is the inventory status of substitute parts?

A: SLPX223M025E7P3 has the highest inventory availability at 5740 pieces. SLPX223M025C9P3 has 1004 pieces available. 380LX series parts have 3125 and 1155 pieces respectively. SLPX223M025H5P3 has 857 pieces available.
