Equivalent & Substitute Parts for EEE-FC1E680AP

Part Overview

The Panasonic EEE-FC1E680AP is a 68 µF, 25 V aluminum electrolytic capacitor in surface mount radial can package, rated for 1000 hours at 105°C with AEC-Q200 automotive qualification. This part carries a "Not For New Designs" status, making equivalent and substitute parts necessary for ongoing production and new design implementations. The FC series represents a legacy product line, and alternative solutions from both Panasonic and other manufacturers provide equivalent or enhanced performance characteristics for the same functional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the EEE-FC1E680AP is determined by the following critical parameters:

Primary Matching Criteria:

• Capacitance: 68 µF (exact match required)
• Voltage Rating: 25 V minimum (equal or higher acceptable)
• Tolerance: ±20% (standard for aluminum electrolytic capacitors)
• Package: Radial, Can - SMD with identical land pattern (0.327" L x 0.327" W)
• Mounting: Surface Mount configuration
• Compliance: AEC-Q200 automotive qualification

Secondary Compatibility Factors:

• Physical dimensions within PCB footprint constraints (case diameter 8.00mm, height 10.20mm - 10.50mm)
• Polarization: Polar (standard for aluminum electrolytic capacitors)
• Moisture Sensitivity Level: MSL 1 (Unlimited)
• RoHS and REACH compliance status

The three substitute parts listed below meet these criteria with varying enhancements in product status, lifetime rating, and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

EEE-FC1E680P (Panasonic): Direct equivalent with identical electrical and mechanical specifications. Maintains the same 25 V rating, 1000-hour lifetime, and operating temperature range as the main part. Suitable for direct replacement in existing designs. Carries "Not For New Designs" status, consistent with the legacy FC series classification.

EEE-FK1J680UP (Panasonic): Enhanced substitute with higher voltage rating (63 V), extended lifetime (2000 hours at 105°C), and expanded operating temperature range (-55°C to 105°C). Represents an active product with ROHS3 compliance. The increased voltage rating provides additional design margin. Height increases to 10.50mm; verify PCB clearance before selection. Lower ripple current rating (250 mA @ 100 kHz) and higher impedance (650 mOhms) require circuit analysis for high-frequency applications.

UWG1E680MNL1GS (Nichicon): Equivalent substitute from alternative manufacturer with matching 25 V rating and 1000-hour lifetime. Active product status with ROHS3 compliance. Maintains identical impedance (300 mOhms) and ripple current capability (450 mA @ 100 kHz) as the main part. Extended operating temperature range (-55°C to 105°C). Height increases to 10.50mm; verify PCB clearance. Suitable for designs requiring multi-source qualification or when Panasonic parts are unavailable.

All three substitutes maintain AEC-Q200 automotive qualification, identical land pattern footprint, and MSL 1 moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK1J680UP be used as a direct replacement for EEE-FC1E680AP?

A: Yes, with design verification. The 63 V rating is compatible with 25 V circuit requirements and provides additional safety margin. However, the increased height (10.50mm vs 10.20mm) requires PCB clearance confirmation. The lower ripple current rating (250 mA vs 450 mA) and higher impedance (650 mOhms vs 300 mOhms) necessitate circuit analysis for high-frequency or high-ripple-current applications.

Q: What is the difference between EEE-FC1E680AP and EEE-FC1E680P?

A: These parts are electrically and mechanically identical. Both carry "Not For New Designs" status and share the same 68 µF, 25 V specifications, 1000-hour lifetime, and operating temperature range. The primary difference is packaging designation (TR vs P suffix). Selection between them depends on inventory availability and supplier preference.

Q: Is UWG1E680MNL1GS suitable for automotive applications?

A: Yes. The Nichicon UWG1E680MNL1GS carries AEC-Q200 qualification and is rated for automotive use. It maintains equivalent electrical performance to the main part with identical impedance and ripple current ratings. Verify that your design qualifications accept multi-source components from both Panasonic and Nichicon manufacturers.

Q: What are the physical constraints when substituting with EEE-FK1J680UP or UWG1E680MNL1GS?

A: Both parts increase height to 10.50mm compared to the main part's 10.20mm. The case diameter (8.00mm) and land pattern (8.30mm x 8.30mm) remain identical. Confirm PCB clearance above the capacitor location before design implementation.

Q: Why does EEE-FK1J680UP have lower ripple current rating than the main part?

A: The EEE-FK1J680UP is rated for 250 mA ripple current at 100 kHz versus 450 mA for the main part, despite identical capacitance and voltage. This reflects different internal construction and thermal characteristics of the FK series. For applications requiring high ripple current handling, EEE-FC1E680P or UWG1E680MNL1GS are preferred.

Q: Are all substitute parts RoHS compliant?

A: Yes. EEE-FC1E680AP and EEE-FC1E680P are RoHS Compliant. EEE-FK1J680UP and UWG1E680MNL1GS are ROHS3 Compliant, representing updated compliance standards. All parts are REACH Unaffected.
