Substitute Part Grouping Explanation

Substitute parts for the ECO-S1KP472CA are classified based on the following substitution criteria:

Direct Equivalents maintain all critical electrical parameters: 4700 µF capacitance, ±20% tolerance, 80 V rated voltage, 3000 hour lifetime at 85°C, and identical lead spacing (10.00 mm). These parts are mechanically and electrically interchangeable with the original part.

Similar Parts share the same electrical specifications (capacitance, voltage, tolerance, temperature range) and package type but may differ in physical dimensions (diameter and height), ESR characteristics, or ripple current ratings. These parts require mechanical verification for PCB layout compatibility.

Parametric Equivalents meet all electrical requirements and maintain the same package footprint as the original part but may have different ESR values or ripple current specifications within acceptable operating ranges.

The following parameters determine substitution eligibility:

Capacitance: 4700 µF (exact match required)
Voltage Rating: 80 V (exact match required)
Tolerance: ±20% (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Lead Spacing: 10.00 mm (exact match required for direct equivalents)
Operating Temperature: -40°C ~ 85°C (exact match required)

Engineering Selection Recommendations

For Direct Replacement (Identical Footprint): SLPX472M080C9P3 is the optimal choice for direct PCB replacement. It maintains the exact physical dimensions of the original ECO-S1KP472CA (0.984" diameter, 1.969" height) while providing active product status and RoHS3 compliance. The 71 mOhm ESR is within acceptable operating parameters for this capacitor category.

For Applications Requiring Extended Lifetime: 380LX472M080J052 and 380LX472M080K042 both provide 3000-hour lifetime at 85°C matching the original specification. Both are manufactured by Cornell Dubilier Electronics and carry RoHS3 compliance. Selection between these depends on available PCB space: 380LX472M080J052 maintains the original 25.00 mm diameter, while 380LX472M080K042 offers a more compact 42.00 mm height with 30.00 mm diameter.

For Space-Constrained Designs: SLPX472M080H3P3 provides the most compact profile (1.181" height, 1.378" diameter) while maintaining all electrical specifications. This part is suitable for applications where vertical clearance is limited.

For Reduced Lifetime Applications: B41231A478M from EPCOS - TDK Electronics is suitable only for applications where 2000-hour lifetime at 85°C is acceptable. This part offers active status and RoHS3 compliance but does not match the original 3000-hour specification.

All substitute parts maintain the required 80 V rating, 4700 µF capacitance, ±20% tolerance, and -40°C to 85°C operating temperature range. Lead spacing remains constant at 10.00 mm across all options.

Frequently Asked Questions (FAQ)

Q: Can SLPX472M080C9P3 be used as a direct replacement for ECO-S1KP472CA? A: Yes. SLPX472M080C9P3 maintains identical physical dimensions (0.984" diameter, 1.969" height) and electrical specifications (4700 µF, 80 V, ±20%, 3000 Hrs @ 85°C). The 71 mOhm ESR is within acceptable operating range for this capacitor category. No PCB layout modifications are required.

Q: What is the difference between the CDE 380LX and SLPX series substitutes? A: Both series meet the electrical requirements but differ in physical dimensions and ESR characteristics. The 380LX series has 65 mOhm ESR, while the SLPX series has 71 mOhm ESR. Physical dimensions vary by part number within each series. Selection depends on available PCB space and thermal management requirements.

Q: Is B41231A478M compatible with the original ECO-S1KP472CA? A: B41231A478M shares the same electrical specifications (4700 µF, 80 V, ±20%) and package type but provides only 2000-hour lifetime at 85°C compared to the original 3000-hour specification. Use this part only in applications where reduced lifetime is acceptable.

Q: Do all substitute parts have the same lead spacing? A: Yes. All substitute parts maintain 10.00 mm lead spacing, ensuring compatibility with existing PCB hole patterns designed for the original ECO-S1KP472CA.

Q: Which substitute part has the best availability? A: SLPX472M080H3P3 has the highest inventory (11,422 pieces in stock), followed by 380LX472M080J052 (2,097 pieces). Both are active products with immediate availability.

Q: Are all substitute parts RoHS3 compliant? A: All substitute parts listed are either RoHS3 compliant or REACH unaffected. The original ECO-S1KP472CA is REACH affected. Verify compliance requirements for your specific application before selection.
