Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EEE-FC1C680AP are qualified based on the following electrical and mechanical parameters:

• Capacitance: 68 µF (exact match required)
• Voltage Rating: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package: Radial, Can - SMD (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Lifetime: 1000 Hrs @ 105°C (exact match required)
• Physical Dimensions: 0.315" Dia (8.00mm), Height ≤ 0.256" (6.50mm)
• Surface Mount Land Size: 0.327" L x 0.327" W (8.30mm x 8.30mm)
• AEC-Q200 Rating: Required for automotive applications
• RoHS Compliance: Required

Two substitute parts meet these criteria: EEE-FC1C680P (Panasonic) and UWG1C680MCL1GS (Nichicon).

Parameter Comparison

Engineering Selection Recommendations

EEE-FC1C680P serves as a direct Panasonic equivalent with identical electrical specifications and physical dimensions. Both Panasonic parts maintain "Not For New Designs" status, indicating end-of-life trajectory.

UWG1C680MCL1GS from Nichicon is the recommended substitute for new designs. This part maintains full electrical equivalence with identical capacitance, voltage rating, tolerance, lifetime, and impedance specifications. The Nichicon part carries "Active" product status, ensuring long-term availability. Operating temperature range extends to -55°C (versus -40°C minimum for Panasonic variants), providing broader thermal coverage. Height dimension increases by 0.012" (0.30mm) to 0.256" (6.50mm), which remains within typical PCB layout tolerances for radial can SMD packages. Both parts share identical surface mount land sizes and AEC-Q200 qualification for automotive applications. RoHS3 compliance of the Nichicon part exceeds RoHS requirements.

Low frequency ripple current specification for UWG1C680MCL1GS is 115 mA at 120 Hz, compared to 172.5 mA for Panasonic variants. High frequency ripple current at 100 kHz remains equivalent at 230 mA across all three parts.

Frequently Asked Questions (FAQ)

Q: Can EEE-FC1C680P be used as a direct replacement for EEE-FC1C680AP?

A: Yes. EEE-FC1C680P is electrically and mechanically identical to EEE-FC1C680AP. Both parts share the same capacitance (68 µF), voltage rating (16 V), tolerance (±20%), package type (Radial, Can - SMD), physical dimensions, impedance (400 mOhms), and AEC-Q200 qualification. The primary difference is inventory availability and product status classification.

Q: Is UWG1C680MCL1GS suitable for automotive applications?

A: Yes. UWG1C680MCL1GS carries AEC-Q200 qualification, meeting automotive reliability standards. The part is electrically equivalent with identical capacitance, voltage rating, tolerance, lifetime (1000 Hrs @ 105°C), and impedance specifications.

Q: What is the height difference between EEE-FC1C680AP and UWG1C680MCL1GS?

A: UWG1C680MCL1GS has a maximum seated height of 0.256" (6.50mm) compared to 0.244" (6.20mm) for EEE-FC1C680AP. This 0.012" (0.30mm) difference is within standard PCB layout tolerances for radial can SMD packages and does not affect footprint compatibility, as both parts use identical surface mount land sizes of 0.327" L x 0.327" W (8.30mm x 8.30mm).

Q: Why is the low frequency ripple current lower for UWG1C680MCL1GS?

A: UWG1C680MCL1GS specifies 115 mA ripple current at 120 Hz, while Panasonic variants specify 172.5 mA. This difference reflects manufacturer design characteristics and does not affect substitution validity. High frequency ripple current at 100 kHz is equivalent at 230 mA across all parts. Circuit design should reference the specific ripple current specification of the selected part.

Q: Are all three parts RoHS compliant?

A: Yes. EEE-FC1C680AP and EEE-FC1C680P are RoHS Compliant. UWG1C680MCL1GS is ROHS3 Compliant, which exceeds RoHS requirements and provides enhanced environmental compliance.

Q: What is the difference in product status between these parts?

A: EEE-FC1C680AP and EEE-FC1C680P are classified as "Not For New Designs," indicating these parts are in end-of-life phase. UWG1C680MCL1GS carries "Active" status, ensuring continued manufacturing and long-term availability for new designs and production continuity.
