Substitute Part Grouping Explanation

Substitution of the ECO-S1KP472DA is determined by strict equivalence across the following critical parameters:

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: 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 minimum (equal or greater acceptable)

Substitute parts are classified into three categories:

Direct Substitutes: Parts meeting all critical parameters with identical or superior electrical performance characteristics.

Similar Substitutes: Parts meeting all critical parameters but with dimensional variations (case diameter or height) that may require PCB layout verification.

Parametric Equivalents: Parts meeting all critical parameters with minor variations in ESR or ripple current ratings within acceptable engineering tolerances.

Engineering Selection Recommendations

Direct Substitutes (Preferred for Pin-Compatible Replacement):

380LX472M080K042 (Cornell Dubilier Electronics) and SLPX472M080E7P3 (Cornell Dubilier Electronics) are the primary direct substitutes. Both maintain the 30.00 mm case diameter and meet or exceed the original specifications. The 380LX472M080K042 features a height of 42.00 mm (2 mm taller than original) and 65 mOhm ESR. The SLPX472M080E7P3 matches the original 40.00 mm height with 71 mOhm ESR. Both parts are ROHS3 compliant and carry active product status.

Alternative Direct Substitutes:

80USG4700MEFCSN30X40 (Rubycon) maintains identical case dimensions (30.00 mm diameter, 42.00 mm height) and meets all electrical parameters. This part is ROHS3 compliant and active.

Substitutes Requiring PCB Layout Verification:

380LX472M080J052 and SLPX472M080C9P3 feature reduced case diameter (25.00 mm) with increased heights (52.00 mm and 50.00 mm respectively). These parts meet all electrical specifications but require verification that PCB footprint and clearance accommodate the dimensional changes.

Conditional Substitute (Reduced Lifetime):

B41231B478M (EPCOS - TDK Electronics) provides a 2000-hour lifetime at 85°C, which is 1000 hours less than the original specification. This part is suitable only for applications where reduced operational lifetime is acceptable. It is ROHS3 compliant and active.

All substitute parts maintain the same lead spacing (10.00 mm), operating temperature range (-40°C to 85°C), and through-hole mounting configuration as the original ECO-S1KP472DA.

Frequently Asked Questions (FAQ)

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

A: Substitutes with different case diameters (such as 380LX472M080J052 at 25.00 mm or SLPX472M080H3P3 at 35.00 mm) require PCB layout verification. The lead spacing remains constant at 10.00 mm, but the physical footprint changes. Verify that the new case diameter does not interfere with adjacent components or violate clearance requirements before implementation.

Q: What is the significance of ESR differences among substitutes?

A: ESR (Equivalent Series Resistance) affects ripple current handling and heat dissipation. The original ECO-S1KP472DA specifies 63 mOhm at 120 Hz. Substitutes with higher ESR values (65 mOhm or 71 mOhm) will generate slightly more heat under ripple current conditions. For applications with high ripple current demands, select substitutes with ESR values closest to the original specification.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed (380LX472M080K042, 80USG4700MEFCSN30X40, B41231B478M, 380LX472M080J052, SLPX472M080C9P3, SLPX472M080H3P3, and SLPX472M080E7P3) are ROHS3 compliant. The original ECO-S1KP472DA is obsolete and does not carry RoHS certification.

Q: What is the impact of using B41231B478M with 2000-hour lifetime instead of 3000 hours?

A: The B41231B478M provides 2000 hours of rated lifetime at 85°C, compared to 3000 hours for the original part. This represents a 33% reduction in operational life expectancy. Use this substitute only in applications where the reduced lifetime does not compromise system reliability requirements or where the application duty cycle is significantly lower than the rated lifetime.

Q: Which substitute offers the best direct replacement without PCB modifications?

A: SLPX472M080E7P3 provides the closest dimensional match to the original ECO-S1KP472DA, maintaining both the 30.00 mm case diameter and 40.00 mm height. This part requires no PCB layout changes and is fully active with ROHS3 compliance.

Q: Can I interchange parts from different manufacturers?

A: Yes. All listed substitutes meet the critical electrical parameters (4700 µF, 80 V, ±20% tolerance, 3000-hour lifetime minimum) and physical specifications (10.00 mm lead spacing, through-hole mounting, snap-in package). Manufacturer differences do not affect functional compatibility provided all specified parameters match.
