Substitute Part Grouping Explanation

Substitute parts are organized into three categories based on substitution type and voltage rating:

Direct Equivalent (Same Voltage Rating - 10V):

UUD1A680MCL1GS (Nichicon): Identical electrical specifications with AEC-Q200 automotive qualification and lower impedance (440 mOhms vs 550 mOhms). Height difference of 0.023" (6.10mm vs 5.50mm) requires PCB layout verification.

Voltage Upgrade Substitutes (16V Rating):

865080343008 (Würth Elektronik): Same manufacturer, WCAP-ASLI series, improved ripple current handling and lower impedance (540 mOhms).
EEE-FP1C680AP (Panasonic): AEC-Q200 rated, automotive-grade with specified ESR of 260 mOhm @ 100kHz and superior ripple current performance (195 mA @ 120 Hz, 300 mA @ 100 kHz).
UCL1C680MCL1GS (Nichicon): General purpose grade with lowest impedance (260 mOhms) and highest ripple current capability (150 mA @ 120 Hz, 300 mA @ 100 kHz).
UUD1C680MCL1GS (Nichicon): AEC-Q200 automotive-grade with same height as UUD1A680MCL1GS (0.240").

Voltage Upgrade Substitutes (25V Rating):

865080443009 (Würth Elektronik): Same manufacturer, WCAP-ASLI series, lowest impedance (480 mOhms) and highest ripple current (156 mA @ 120 Hz, 240 mA @ 100 kHz).
EEE-FP1E680AP (Panasonic): AEC-Q200 rated, automotive-grade with specified ESR of 260 mOhm @ 100kHz and superior ripple current performance (195 mA @ 120 Hz, 300 mA @ 100 kHz).
UUD1E680MCL1GS (Nichicon): AEC-Q200 automotive-grade with same height as UUD1C680MCL1GS (0.240").

Substitution logic is based on: identical capacitance (68 µF), identical tolerance (±20%), identical operating temperature range (-55°C ~ 105°C), identical lifetime rating (2000 Hrs @ 105°C), identical physical diameter (6.30mm), identical land size (6.60mm x 6.60mm), and identical mounting type (Surface Mount). Voltage ratings of 16V and 25V are backward compatible with 10V applications.

Engineering Selection Recommendations

For Direct Replacement (Same Voltage, 10V): UUD1A680MCL1GS is the only direct equivalent. It carries AEC-Q200 automotive qualification, which provides additional reliability assurance. The 0.023" height increase must be evaluated against PCB clearance constraints. The lower impedance (440 mOhms vs 550 mOhms) provides improved high-frequency performance.

For Voltage Upgrade to 16V:

Würth Elektronik 865080343008: Maintains original manufacturer and series continuity with minimal height change. Suitable for designs requiring same-source component strategy.
Panasonic EEE-FP1C680AP: Offers AEC-Q200 certification and lowest impedance (260 mOhms) with superior ripple current ratings. Recommended for high-ripple-current applications.
Nichicon UCL1C680MCL1GS: General purpose grade with lowest impedance and highest ripple current capability. Suitable for non-automotive applications with demanding ripple current requirements.
Nichicon UUD1C680MCL1GS: AEC-Q200 automotive-grade alternative with same height profile as UUD1A680MCL1GS.

For Voltage Upgrade to 25V:

Würth Elektronik 865080443009: Maintains original manufacturer and series continuity with lowest impedance in 25V category (480 mOhms).
Panasonic EEE-FP1E680AP: AEC-Q200 certified with lowest impedance (260 mOhms) and superior ripple current performance. Recommended for automotive and high-ripple-current applications.
Nichicon UUD1E680MCL1GS: AEC-Q200 automotive-grade with same height profile as UUD1C680MCL1GS.

All substitute parts maintain ROHS3 compliance and MSL 1 rating. Selection should prioritize AEC-Q200 certification for automotive applications and impedance/ripple current specifications for high-frequency or high-current designs.

Frequently Asked Questions (FAQ)

Q: Can I use a 16V or 25V rated capacitor in place of the 10V part? A: Yes. Higher voltage-rated capacitors are backward compatible with lower voltage applications. The 16V and 25V rated substitutes provide additional design margin and are electrically suitable for 10V circuits.

Q: What is the significance of impedance differences between parts? A: Impedance affects high-frequency performance and ripple current handling. Lower impedance (260 mOhms in Panasonic and Nichicon UCL series) provides better performance in high-frequency applications. The original part has 550 mOhms impedance; substitutes range from 260 to 540 mOhms.

Q: Does the height difference matter? A: Yes. The original part is 0.217" (5.50mm) tall. Nichicon UUD series parts are 0.240" (6.10mm), and Panasonic FP series are 0.228" (5.80mm). PCB layout and component clearance must be verified before substitution.

Q: What does AEC-Q200 certification mean? A: AEC-Q200 is an automotive qualification standard indicating the component meets reliability and performance requirements for automotive applications. Parts with this certification are suitable for automotive use; parts without it are general purpose grade.

Q: Are all substitutes available in the same packaging? A: Yes. All listed substitutes are supplied in Tape & Reel (TR) packaging for surface mount assembly, matching the original part's packaging format.

Q: Which substitute offers the best ripple current performance? A: Panasonic EEE-FP1C680AP (16V) and EEE-FP1E680AP (25V) offer the highest ripple current ratings: 195 mA @ 120 Hz and 300 mA @ 100 kHz. Nichicon UCL1C680MCL1GS also provides 300 mA @ 100 kHz ripple current.

Q: Can I mix different manufacturers in the same design? A: Yes. All substitutes meet identical electrical specifications for capacitance, tolerance, voltage, temperature range, and lifetime. Mixing manufacturers is acceptable provided PCB layout accommodates any height variations and procurement logistics are managed.
