Substitute Part Grouping Explanation

Substitution for the ECO-S2AP272DA is determined by strict equivalence across the following parameters:

Capacitance value: 2700 µF (exact match required)
Voltage rating: 100 V (exact match required)
Tolerance: ±20% (exact match required)
Package configuration: Radial, Can - Snap-In (exact match required)
Lead spacing: 0.394" (10.00 mm) (exact match required)
Diameter: 1.181" (30.00 mm) (exact match required)
Mounting type: Through Hole (exact match required)
Operating temperature range: -40°C ~ 85°C (exact match required)
Lifetime rating: 3000 Hrs @ 85°C (exact match required)

Two substitute parts meet these criteria and are identified as direct equivalents.

Engineering Selection Recommendations

Both substitute parts—380LX272M100K032 and SLPX272M100E5P3 from Cornell Dubilier Electronics—are active products with current manufacturing status, addressing the obsolescence of the ECO-S2AP272DA. Both substitutes maintain electrical equivalence across all critical parameters: capacitance, voltage rating, tolerance, ESR, lifetime rating, and operating temperature range.

The 380LX272M100K032 exhibits a maximum seated height of 1.457" (37.00 mm), which exceeds the original part's 1.378" (35.00 mm) by 0.079" (2.00 mm). This dimensional difference requires verification against PCB layout constraints and mechanical clearance requirements.

The SLPX272M100E5P3 maintains identical height to the original part at 1.378" (35.00 mm) and offers a marginally lower ESR of 98 mOhm compared to the original 104 mOhm, providing improved performance characteristics. Both substitutes are ROHS3 compliant, whereas the original part is non-compliant.

Frequently Asked Questions (FAQ)

Q: Can the 380LX272M100K032 be used as a direct replacement despite the height difference?

A: The 380LX272M100K032 meets all electrical specifications and maintains the same lead spacing and diameter. However, the increased seated height of 1.457" (37.00 mm) versus the original 1.378" (35.00 mm) requires confirmation that PCB layout and mechanical clearance accommodate this 2.00 mm difference. Physical verification against the assembly drawing is necessary.

Q: What is the significance of the ESR difference between SLPX272M100E5P3 and the original part?

A: The SLPX272M100E5P3 has an ESR of 98 mOhm at 120 Hz compared to the original 104 mOhm. Lower ESR reduces heat generation and improves ripple current handling. This represents an improvement over the original specification and does not compromise compatibility.

Q: Are both substitute parts suitable for new designs?

A: Both 380LX272M100K032 and SLPX272M100E5P3 are active products with current manufacturing status. Selection between them depends on mechanical constraints (height clearance) and compliance requirements. Both are ROHS3 compliant, making them suitable for applications requiring modern regulatory compliance.

Q: What is the impact of the ±20% capacitance tolerance on circuit performance?

A: All three parts—original and substitutes—share identical ±20% tolerance. This tolerance is inherent to the capacitance value and application class. Circuit design must account for this tolerance range; substitution does not introduce additional tolerance variation.

Q: Can these parts be used interchangeably in existing assemblies?

A: Electrical interchangeability is confirmed across all critical parameters. Mechanical interchangeability requires verification of the seated height against available PCB clearance. The SLPX272M100E5P3 provides direct mechanical compatibility with the original part's height specification.
