ECO-S2EP152EA Equivalent & Substitute Parts

Part Overview

The ECO-S2EP152EA is a 1500 µF, 250 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Panasonic Electronic Components. This part operates across -40°C to 85°C with a rated lifetime of 3000 hours at 85°C and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for ongoing system support and new designs requiring this capacitance and voltage rating.

Engineering Selection Recommendations

Direct Equivalents (Preferred for Drop-In Replacement):

SLPX152M250H4P3, 380LX152M250A052, and LLS2E152MELC meet all core electrical and mechanical parameters with active product status and ROHS3 compliance. These parts are suitable for direct substitution where the original ECO-S2EP152EA footprint and performance are required.

Superior Performance Alternative:

B43501B2158M000 from EPCOS - TDK Electronics provides enhanced reliability with 10000 hours lifetime at 85°C and lower ESR (65 mOhm @ 100Hz) compared to the original 133 mOhm specification. This part maintains identical capacitance, voltage, and lead spacing, making it suitable for applications requiring extended operational life.

Extended Temperature Operation:

LGU2E152MELC from Nichicon extends the maximum operating temperature to 105°C while maintaining 3000 hours lifetime. This upgrade is applicable for systems requiring higher thermal margins or operation in elevated ambient conditions.

Reduced Lifetime Alternatives:

380LQ152M250A042 and 380LQ152M250K052 provide 2000 hours lifetime at 85°C, which is reduced compared to the original 3000 hours specification. These parts are suitable only where application duty cycles permit shorter service intervals.

Limited Lifetime Alternative:

LPX152M250H9P3 provides only 1000 hours lifetime at 85°C and is suitable only for non-critical applications or short-term use cases.

Dimensional Considerations:

250USG1500MEFCSN30X50 and 380LQ152M250K052 feature a reduced case diameter of 30.00 mm compared to the standard 35.00 mm. Mechanical validation is required to confirm PCB layout compatibility before selection.

All recommended substitutes carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with modern manufacturing standards.

Frequently Asked Questions (FAQ)

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

A: Parts with case diameter variations (30.00 mm vs. 35.00 mm) require mechanical validation. PCB mounting holes, clearance to adjacent components, and thermal dissipation paths must be verified before substitution. Consult your PCB layout documentation and thermal analysis.

Q: What is the impact of ESR differences between substitute parts?

A: ESR affects ripple current handling and heat generation. The original ECO-S2EP152EA specifies 133 mOhm @ 120Hz. Substitutes with higher ESR (such as 158LBB250M2EH at 165.786 mOhm) generate more heat under ripple current stress. The B43501B2158M000 with 65 mOhm provides superior performance. Verify your application's ripple current requirements against the substitute part's ripple current rating.

Q: Can I use a substitute with reduced lifetime hours?

A: Lifetime ratings reflect expected service hours under specified conditions (temperature, ripple current, voltage stress). Parts with reduced lifetime (2000 or 1000 hours vs. 3000 hours) are suitable only if your application duty cycle is compatible. Calculate expected operating hours and compare against the substitute part's rating.

Q: Is the LGU2E152MELC upgrade suitable for my application?

A: The LGU2E152MELC extends maximum operating temperature to 105°C and maintains 3000 hours lifetime. This upgrade is beneficial for applications with elevated ambient temperatures or thermal stress. Verify that your system can accommodate the extended temperature range without adverse effects on other components.

Q: What does ROHS3 compliance mean?

A: ROHS3 compliance indicates the part meets the Restriction of Hazardous Substances Directive 3, restricting lead, cadmium, mercury, and other hazardous materials. All active substitute parts listed carry ROHS3 compliance, ensuring compatibility with modern manufacturing and environmental regulations.

Q: Are all substitute parts pin-compatible?

A: Yes. All substitute parts maintain the 0.394" (10.00 mm) lead spacing and radial, can snap-in package configuration. Pin compatibility is confirmed across all listed alternatives.

Q: What is the difference between "Active" and "Obsolete" product status?

A: Active parts are currently manufactured and supported by the supplier with ongoing availability. Obsolete parts are no longer manufactured and availability is limited to existing inventory. The original ECO-S2EP152EA is obsolete; all listed substitutes carry active status, ensuring long-term supply chain reliability.
