Substitute Part Grouping Explanation

Substitution relationships for the EEU-EB2C680 are determined by the following allowable parameter variations:

Voltage Rating Upgrade: Parts with higher voltage ratings (200 V) are direct upgrades when the circuit design permits increased voltage margin. These maintain identical capacitance, tolerance, and physical dimensions.

Lifetime Rating Upgrade: Parts with extended lifetime ratings (10000 Hrs @ 105°C versus 5000 Hrs @ 105°C) provide enhanced reliability for applications requiring longer operational life.

Series Variation: Different series designations (EB-A, ED-A, EE-A) indicate different internal construction and performance characteristics. Substitution within series families is permitted when capacitance, voltage, and tolerance remain constant.

Physical Dimension Tolerance: Lead spacing and case diameter variations are acceptable only when the circuit board layout and mounting footprint can accommodate the dimensional changes.

The following parts are identified as substitutes based on these criteria:

EEU-EB2D680: Voltage upgrade (200 V), same series, identical physical dimensions
EEU-ED2D680: Voltage upgrade (200 V) with extended lifetime (10000 Hrs), different series
EEU-EB2C680S: Same voltage and lifetime, different physical dimensions (larger case)
EEU-ED2C680: Same voltage with extended lifetime (10000 Hrs), different series
EEU-EE2C680: Same voltage with extended lifetime (10000 Hrs), different series

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the main part specification. Selection among equivalent parts should be based on the following circuit-level requirements:

For voltage margin enhancement: EEU-EB2D680 provides a direct dimensional replacement with 200 V rating while maintaining the EB-A series characteristics and 5000-hour lifetime.

For extended operational life: EEU-ED2D680 combines 200 V rating with 10000-hour lifetime, though height is reduced to 0.984" (25.00 mm). EEU-ED2C680 and EEU-EE2C680 provide 10000-hour lifetime at the original 160 V rating with varying physical dimensions.

For footprint compatibility: EEU-EB2C680S maintains identical voltage and lifetime specifications but requires verification of lead spacing (0.295" versus 0.197") and case diameter (0.630" versus 0.492") compatibility with the circuit board layout.

All substitute parts are active production items with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can EEU-EB2D680 be used as a direct replacement for EEU-EB2C680?

A: Yes. EEU-EB2D680 is a direct replacement with identical physical dimensions, lead spacing, and mounting footprint. The 200 V rating provides additional voltage margin while maintaining the same 68 µF capacitance and ±20% tolerance. Both parts are EB-A series with 5000-hour lifetime at 105°C.

Q: What is the difference between EEU-ED2D680 and EEU-EB2D680?

A: Both parts have 68 µF capacitance and 200 V rating. EEU-ED2D680 is ED-A series with 10000-hour lifetime and slightly reduced height (0.984" versus 1.063"). EEU-EB2D680 is EB-A series with 5000-hour lifetime. The ED-A series offers extended reliability at the cost of reduced height clearance.

Q: Can EEU-EB2C680S be used in place of EEU-EB2C680?

A: Substitution requires verification of circuit board layout compatibility. While both parts have identical voltage, capacitance, and lifetime specifications, EEU-EB2C680S has different physical dimensions: lead spacing of 0.295" (versus 0.197"), diameter of 0.630" (versus 0.492"), and height of 0.866" (versus 1.063"). The larger case diameter and wider lead spacing may not fit the original mounting footprint.

Q: Which substitute part offers the longest operational life?

A: EEU-ED2D680, EEU-ED2C680, and EEU-EE2C680 all provide 10000-hour lifetime at 105°C, compared to 5000 hours for the main part. EEU-ED2D680 additionally provides 200 V rating for enhanced voltage margin.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status consistent with EEU-EB2C680.

Q: What is the difference between ED-A and EE-A series capacitors?

A: Both ED-A and EE-A series provide 10000-hour lifetime at 105°C. EEU-EE2C680 has higher ripple current ratings (472.5 mA @ 120 Hz and 1.35 A @ 100 kHz) compared to EEU-ED2C680 (380 mA @ 120 Hz and 950 mA @ 100 kHz). Selection depends on circuit ripple current requirements.
