Engineering Selection Recommendations

Direct Substitutes (Preferred for Drop-In Replacement):

80MXG6800MEFCSN35X40 (Rubycon MXG Series) and 80MXG6800MEFCSN30X50 (Rubycon MXG Series) are active-status components meeting all electrical and mechanical specifications. Both are ROHS3 compliant and REACH unaffected. The 80MXG6800MEFCSN35X40 variant maintains identical diameter (35mm) and lead spacing (10mm) to the original part, with reduced height (42mm vs. 52mm), enabling direct PCB installation. The 80MXG6800MEFCSN30X50 variant features a reduced diameter (30mm) and identical height (52mm), requiring mechanical clearance verification.

Direct Substitutes (Mechanical Variation):

LGU1K682MELC (Nichicon LGU Series) is an active-status ROHS3 compliant component with identical electrical specifications and 35mm diameter. Height is 47mm, representing a 5mm reduction from the original. Lead spacing matches at 10mm. This part is suitable for applications with vertical space constraints.

SLP682M080H4P3 (Cornell Dubilier Electronics SLP Series) is an active-status ROHS3 compliant component with matching electrical specifications and 35mm diameter. Height is 45mm, representing a 7mm reduction. ESR is 49mOhm, slightly higher than the original 41mOhm. This part is suitable for space-constrained applications where ESR variation is acceptable.

Similar Substitute (4-Lead Configuration):

383LX682M080A052 (Cornell Dubilier Electronics 383LX Series) is an active-status ROHS3 compliant component with matching electrical specifications and 35mm diameter. This part features a 4-lead configuration and 52mm height matching the original. Lead spacing is not specified and requires verification before installation. The 4-lead design may require PCB layout modification.

Parametric Equivalent (Performance Variation):

688LMB080M2EH (Cornell Dubilier / Illinois Capacitor LMB Series) is an active-status ROHS3 compliant component meeting all electrical specifications with 35mm diameter and 52mm height. ESR is 60.9509mOhm, significantly higher than the original 41mOhm. This part is suitable only for applications where higher ESR is acceptable.

Frequently Asked Questions (FAQ)

Q: Can I use 80MXG6800MEFCSN30X50 as a direct replacement for ECO-S1KA682EA?

A: The 80MXG6800MEFCSN30X50 meets all electrical specifications and lead spacing requirements. However, its diameter is reduced to 30mm compared to the original 35mm. Direct PCB replacement is possible only if the PCB layout accommodates the smaller diameter. Mechanical clearance verification is required.

Q: What is the difference between the two Rubycon MXG variants?

A: Both 80MXG6800MEFCSN35X40 and 80MXG6800MEFCSN30X50 are electrically identical. The primary difference is physical: the 35X40 variant maintains the original 35mm diameter with reduced height (42mm), while the 30X50 variant has reduced diameter (30mm) with original height (52mm). Select based on available PCB space.

Q: Why does 383LX682M080A052 have a 4-lead configuration?

A: The 383LX682M080A052 features a 4-lead snap-in design, which differs from the standard 2-lead configuration of the original part. This configuration may require PCB layout modification and is classified as a similar substitute rather than a direct replacement.

Q: Is 688LMB080M2EH suitable for my application?

A: The 688LMB080M2EH meets all electrical specifications and physical dimensions. However, its ESR of 60.9509mOhm is significantly higher than the original 41mOhm. This part is suitable only for applications where higher ESR does not impact performance. Applications sensitive to ESR characteristics should select alternatives with lower ESR values.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant. The original ECO-S1KA682EA RoHS status is not specified in the provided data.

Q: What is the primary reason for substitution?

A: The ECO-S1KA682EA is classified as obsolete. All listed substitutes are active-status components from established manufacturers, ensuring long-term availability and supply chain continuity.

Q: Do all substitutes have identical lead spacing?

A: All substitutes except 383LX682M080A052 have confirmed lead spacing of 0.394" (10.00mm), matching the original part. The 383LX682M080A052 lead spacing is not specified and requires verification.
