Substitute Part Grouping Explanation

Substitution of the ECO-S1EP332BA is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 3300 µF (exact match required)
• Voltage Rating: 25 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)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -40°C to 85°C (minimum requirement)
• Lifetime Rating: 3000 Hrs @ 85°C (minimum requirement)

The substitute part 380LX332M025H202 from Cornell Dubilier Electronics meets all mandatory electrical and mechanical parameters. Variations in ESR (Equivalent Series Resistance) and ripple current ratings remain within acceptable operational margins for general-purpose applications while maintaining functional compatibility.

Engineering Selection Recommendations

The 380LX332M025H202 from Cornell Dubilier Electronics is a direct functional equivalent for the obsolete ECO-S1EP332BA. Selection is based on the following engineering criteria:

Electrical Equivalence: Both capacitors maintain identical capacitance (3300 µF), voltage rating (25 V), and tolerance (±20%). The ESR differential of 16 mOhm is negligible for general-purpose applications and does not compromise circuit performance.

Mechanical Compatibility: Lead spacing (10.00 mm), diameter (22.00 mm), and mounting type (through-hole, snap-in) are identical, ensuring direct PCB compatibility without layout modifications.

Operational Reliability: Both parts support the same operating temperature range (-40°C to 85°C) and lifetime rating (3000 Hrs @ 85°C), maintaining equivalent reliability profiles.

Compliance Status: The Cornell Dubilier part is currently active in production with RoHS3 compliance certification, providing superior long-term availability compared to the obsolete Panasonic component.

Physical Consideration: The substitute part has a reduced seated height (22.00 mm vs. 25.00 mm), which may provide additional clearance in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the 380LX332M025H202 be used as a direct replacement for the ECO-S1EP332BA?

A: Yes. Both capacitors share identical electrical specifications (3300 µF, 25 V, ±20% tolerance) and mechanical configurations (radial snap-in, 10.00 mm lead spacing, 22.00 mm diameter). The substitute part is mechanically and electrically compatible for through-hole PCB mounting.

Q: What is the significance of the ESR difference between the two parts?

A: The ECO-S1EP332BA has an ESR of 161 mOhm @ 120 Hz, while the 380LX332M025H202 has 177 mOhm @ 120 Hz. This 16 mOhm difference represents approximately 10% variation and remains within acceptable tolerances for general-purpose capacitor applications. ESR impact on circuit performance is application-dependent and typically negligible in low-frequency filtering and energy storage circuits.

Q: Does the height difference affect PCB compatibility?

A: The substitute part is 3.00 mm shorter (22.00 mm vs. 25.00 mm seated height). This dimensional reduction does not compromise compatibility and may provide additional clearance in applications with height constraints. PCB footprint and lead spacing remain identical.

Q: Is the Cornell Dubilier part currently available?

A: Yes. The 380LX332M025H202 is listed as active product status with RoHS3 compliance, ensuring ongoing availability and supply chain reliability compared to the obsolete Panasonic component.

Q: Are there additional substitute options listed for the Cornell Dubilier part?

A: The 380LX332M025H202 documentation references 380LX332M050H022 as an additional substitute option. Verification of this alternative part's specifications against your application requirements is necessary before selection.
