Engineering Selection Recommendations

For direct replacement of the obsolete ECO-S1KA102CA, the 381LX102M080J012 from Cornell Dubilier Electronics provides electrical and mechanical equivalence. Both parts share identical capacitance, voltage rating, tolerance, lifetime rating, and physical dimensions with 0.394" lead spacing and snap-in package configuration.

The B41505A0108M007 and B41505A0108M000 from EPCOS - TDK Electronics represent active-status upgrade options. These parts maintain the same capacitance, voltage, tolerance, and physical footprint while offering reduced ESR (125 mOhm versus 182 mOhm) and extended lifetime (5000 hours versus 3000 hours at 105°C). Both variants are RoHS3 compliant and REACH unaffected, supporting modern regulatory requirements.

The 381LX102M100J012 from Cornell Dubilier Electronics provides a voltage-upgraded alternative at 100 V rating while preserving all other electrical specifications and physical dimensions. This option is suitable for applications requiring higher voltage margin.

The B41252B108M from EPCOS - TDK Electronics is an active-status equivalent with minor dimensional variation (1.000" case diameter versus 0.984") and reduced lifetime rating (2000 hours). This part is RoHS3 compliant and suitable for applications where extended lifetime is not critical.

The 381LX102M080K202 and SLP102M080A1P3 are similar-category parts with identical electrical specifications but different physical dimensions. These options require mechanical re-evaluation for PCB layout compatibility due to case diameter and height variations.

Frequently Asked Questions (FAQ)

Q: Can the 381LX102M080J012 be used as a direct replacement for ECO-S1KA102CA?

A: Yes. The 381LX102M080J012 matches all critical parameters: 1000 µF capacitance, 80 V voltage rating, ±20% tolerance, 3000-hour lifetime at 105°C, 0.394" lead spacing, 0.984" case diameter, 1.063" seated height, and snap-in radial package configuration. Both are through-hole mounted polar capacitors with identical operating temperature range.

Q: What is the advantage of B41505A0108M007 over the original ECO-S1KA102CA?

A: The B41505A0108M007 maintains electrical and mechanical compatibility while offering two performance improvements: reduced ESR (125 mOhm versus 182 mOhm) and extended lifetime (5000 hours versus 3000 hours at 105°C). The part is active-status and RoHS3 compliant.

Q: Can the 381LX102M100J012 be substituted in place of ECO-S1KA102CA?

A: Yes, with the understanding that this represents a voltage upgrade. The 381LX102M100J012 is rated for 100 V instead of 80 V, maintaining all other specifications including capacitance, tolerance, ESR, lifetime, and physical dimensions. This substitution is suitable for applications where higher voltage margin is beneficial or required.

Q: Why do 381LX102M080K202 and SLP102M080A1P3 require mechanical re-evaluation?

A: These parts differ in physical dimensions. The 381LX102M080K202 has a 1.181" case diameter and 0.866" height, while the SLP102M080A1P3 has a 0.866" case diameter and 0.984" height. The original ECO-S1KA102CA specifies 0.984" diameter and 1.063" height. PCB layout, mounting clearances, and thermal management must be verified before substitution.

Q: Are all substitute parts RoHS3 compliant?

A: The active-status parts B41252B108M, B41505A0108M007, B41505A0108M000, 381LX102M080K202, and SLP102M080A1P3 are RoHS3 compliant. The obsolete-status parts ECO-S1KA102CA and 381LX102M080J012 do not specify RoHS3 compliance. Verify compliance requirements for your application.

Q: What is the lead spacing requirement for all substitutes?

A: All substitute parts maintain the 0.394" (10.00 mm) lead spacing specified for the original ECO-S1KA102CA, ensuring PCB footprint compatibility across direct equivalents and upgrade options.
