Key Parameters

Substitute Part Grouping Explanation

Substitution of the EEE-FC1C680P is determined by strict equivalence across the following critical parameters:

Capacitance value must match at 68 µF with ±20% tolerance. Voltage rating must be 16 V or higher. Lifetime specification must meet or exceed 1000 hours at 105°C. Physical dimensions must be compatible with the 0.315" diameter (8.00mm) and surface mount land size of 0.327" L x 0.327" W (8.30mm x 8.30mm). Impedance and ripple current ratings must support the electrical performance requirements. Package configuration must remain Radial, Can - SMD with surface mount mounting type. Compliance certifications including AEC-Q200 and RoHS must be maintained.

The UWG1C680MCL1GS from Nichicon meets all substitution criteria and is classified as an equivalent upgrade component.

Parameter Comparison

Engineering Selection Recommendations

The UWG1C680MCL1GS qualifies as a direct substitute for the EEE-FC1C680P based on electrical parameter equivalence and compliance certifications. Both components maintain AEC-Q200 qualification and RoHS compliance. The Nichicon part carries Active product status, ensuring continued availability and manufacturing support compared to the Panasonic part's Not For New Designs designation.

The UWG1C680MCL1GS provides an extended operating temperature range of -55°C to 105°C versus the original -40°C to 105°C specification, offering improved performance margin in low-temperature applications. Physical dimensions are compatible with existing PCB layouts, with a maximum height difference of 0.012" (0.30mm) that remains within typical assembly tolerances for surface mount radial can packages.

Frequently Asked Questions (FAQ)

Q: Can the UWG1C680MCL1GS be used as a direct replacement for the EEE-FC1C680P?

A: Yes. Both components share identical capacitance (68 µF), voltage rating (16 V), tolerance (±20%), lifetime specification (1000 Hrs @ 105°C), package type (Radial, Can - SMD), land size (0.327" x 0.327"), and impedance (400 mOhms). AEC-Q200 and RoHS compliance are maintained.

Q: What is the height difference between these two parts?

A: The EEE-FC1C680P has a maximum seated height of 0.244" (6.20mm), while the UWG1C680MCL1GS measures 0.256" (6.50mm). The 0.012" (0.30mm) difference is within standard assembly clearance tolerances for surface mount applications.

Q: Are there differences in ripple current ratings?

A: At 120 Hz, the EEE-FC1C680P is rated for 172.5 mA while the UWG1C680MCL1GS is rated for 115 mA. At 100 kHz, both are rated for 230 mA. Application-specific ripple current requirements should be evaluated against these specifications.

Q: What is the temperature range difference?

A: The EEE-FC1C680P operates from -40°C to 105°C. The UWG1C680MCL1GS extends the lower limit to -55°C, providing a 15°C improvement for cold-temperature applications while maintaining the same 105°C upper limit.

Q: Are both parts RoHS compliant?

A: Yes. The EEE-FC1C680P is RoHS Compliant, and the UWG1C680MCL1GS is ROHS3 Compliant. Both meet current RoHS requirements.
