Substitute Part Grouping Explanation

Substitution eligibility for the ECO-S1CP123CA is determined by strict adherence to the following core parameters:

Capacitance value must equal 12000 µF. Voltage rating must equal or exceed 16 V. Tolerance must be ±20%. Package type must be radial, can snap-in with through-hole mounting. Lead spacing must be 0.394" (10.00 mm). Operating temperature range must span -40°C to 85°C. Lifetime rating must meet or exceed 3000 hours at 85°C.

Substitute parts are grouped into three categories based on substitution relationship type:

Direct equivalents maintain identical electrical and mechanical specifications. Similar parts meet all core parameters but may vary in secondary characteristics such as ESR, ripple current ratings, or physical dimensions within the snap-in package envelope. Parametric equivalents satisfy all mandatory electrical parameters and package requirements but may have undocumented ESR values or different ripple current specifications.

Engineering Selection Recommendations

Selection of substitute parts for the obsolete ECO-S1CP123CA should prioritize active product status and regulatory compliance.

The 380LX123M016J012 from Cornell Dubilier Electronics is the primary direct equivalent, maintaining identical electrical specifications including 62 mOhm ESR and 3000-hour lifetime rating. This part is active and ROHS3 compliant.

The SLPX123M016C1P3 from Cornell Dubilier Electronics provides an alternative with improved ESR performance at 55 mOhm while maintaining the same capacitance, voltage, tolerance, and lifetime specifications. This part is active and ROHS3 compliant. Physical dimensions differ slightly, with reduced height of 0.984" compared to the original 1.063".

The LLS1C123MELA from Nichicon meets all mandatory electrical parameters and maintains identical physical dimensions to the original part. This part is active and ROHS3 compliant, though ESR is not specified in available documentation.

The B41231B4129M000 from EPCOS - TDK Electronics satisfies core electrical and mechanical requirements but features a reduced lifetime rating of 2000 hours at 85°C compared to the 3000-hour specification of the original part. This part is active and ROHS3 compliant.

The 380LX123M016H022 and SLPX123M016A3P3 both feature reduced physical dimensions and lower ripple current ratings, making them suitable only for applications where space constraints override performance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 380LX123M016J012 be used as a direct replacement for the ECO-S1CP123CA?

A: Yes. The 380LX123M016J012 maintains identical capacitance, voltage rating, tolerance, ESR, lifetime rating, and physical dimensions. Lead spacing and package type are identical. The part is active and ROHS3 compliant.

Q: What is the difference between the SLPX123M016C1P3 and the original ECO-S1CP123CA?

A: Both parts share identical capacitance, voltage, tolerance, and lifetime specifications. The SLPX123M016C1P3 features lower ESR at 55 mOhm versus 62 mOhm. Physical height is reduced to 0.984" from 1.063". Lead spacing and diameter remain unchanged.

Q: Why does the B41231B4129M000 have a shorter lifetime rating?

A: The B41231B4129M000 is rated for 2000 hours at 85°C, compared to 3000 hours for the original part. This represents a documented difference in the component's thermal endurance specification. Applications requiring extended operational life at elevated temperatures should prioritize parts with 3000-hour ratings.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts are ROHS3 compliant. The original ECO-S1CP123CA does not specify RoHS status due to its obsolete classification.

Q: Can parts with different physical dimensions be used interchangeably on the same PCB?

A: Physical dimensions must be verified against PCB layout constraints. The 380LX123M016H022 and SLPX123M016A3P3 feature different diameter and height specifications. The SLPX123M016C1P3 has reduced height. Mechanical fit must be confirmed before substitution.

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

A: ESR affects ripple current handling and thermal performance. Lower ESR values improve efficiency and reduce heat generation. The SLPX series parts at 55 mOhm provide better performance than the original 62 mOhm specification. Parts with unspecified ESR should be verified against application ripple current requirements.
