Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEE-FC0J680AP is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 68 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Package / Case: Radial, Can - SMD (exact match required)
• Physical Dimensions: 0.248" Dia (6.30mm) and compatible height (maximum 5.80mm)
• Surface Mount Land Size: 0.260" L x 0.260" W (6.60mm x 6.60mm) (exact match required)
• Polarization: Polar (exact match required)

Allowable Parameter Variations:

• Voltage - Rated: May be equal to or greater than 6.3 V (higher voltage ratings provide backward compatibility)
• Lifetime @ Temperature: May be equal to or greater than 1000 Hrs @ 105°C (extended lifetime is acceptable)
• Operating Temperature Range: May be equal to or broader than -40°C to 105°C
• Product Status: Active status preferred over obsolete status for long-term availability
• Manufacturer: Different manufacturers acceptable if all other parameters align

Substitute Categories:

Direct Equivalents (Same Voltage Rating):

• EEE-FC0J680P (Panasonic, same series, same voltage)
• UWG0J680MCL1GB (Nichicon, same voltage, different series)

Upgraded Substitutes (Higher Voltage Rating):

• EEE-HB1A680AP (Panasonic, 10 V rating, extended lifetime)
• EEE-FP1C680AP (Panasonic, 16 V rating, extended lifetime)
• EEE-FP1E680AP (Panasonic, 25 V rating, extended lifetime)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Characteristics):

EEE-FC0J680P is the primary direct equivalent, maintaining identical electrical specifications and physical dimensions. Both parts are Panasonic FC series components with 6.3 V rating and 1000 hour lifetime at 105°C. The main distinction is product status; EEE-FC0J680P remains classified as "Not For New Designs," indicating limited future availability. This option is suitable for legacy system maintenance and production support where exact specification matching is required.

UWG0J680MCL1GB (Nichicon) provides an alternative direct equivalent with identical electrical and physical parameters. This part carries Active product status, offering superior long-term supply chain availability. The Nichicon UWG series maintains AEC-Q200 automotive qualification and ROHS3 compliance, making it suitable for both legacy support and new production runs.

For Upgraded Substitution (Higher Voltage Rating):

EEE-HB1A680AP (10 V rating) and EEE-FP1C680AP (16 V rating) are Panasonic alternatives with higher voltage ratings and extended 2000-hour lifetime at 105°C. These parts are electrically backward compatible with the 6.3 V application, as higher voltage ratings accommodate lower voltage operation. Both maintain identical physical dimensions and AEC-Q200 automotive qualification. These options are preferred for new designs and long-term production due to Active product status and improved reliability metrics.

EEE-FP1E680AP (25 V rating) represents the highest voltage upgrade option with identical performance characteristics to the 16 V variant. This part offers maximum design margin for voltage stress and is suitable for applications requiring extended component lifetime and superior reliability.

Compliance and Certification:

All substitute parts maintain AEC-Q200 automotive qualification and RoHS compliance. Panasonic FP and HB series parts carry ROHS3 certification, representing the latest regulatory standard. Nichicon UWG series carries ROHS3 compliance. All parts are MSL 1 (Unlimited), eliminating moisture sensitivity concerns for storage and handling.

Frequently Asked Questions (FAQ)

Q: Can EEE-FP1C680AP (16 V) be used in place of EEE-FC0J680AP (6.3 V)?

A: Yes. The EEE-FP1C680AP is electrically backward compatible. A capacitor with higher voltage rating can operate safely at lower voltages. The 16 V rating provides additional design margin and stress relief. Physical dimensions are compatible with identical land size footprints. The primary consideration is circuit board layout clearance, as the EEE-FP1C680AP has maximum height of 5.80mm compared to 5.40mm for the original part.

Q: What is the difference between EEE-FC0J680P and UWG0J680MCL1GB?

A: Both parts are direct electrical equivalents with identical 68 µF, 6.3 V specifications and physical dimensions. The primary differences are manufacturer (Panasonic vs. Nichicon) and product status. EEE-FC0J680P is Panasonic FC series with "Not For New Designs" status. UWG0J680MCL1GB is Nichicon UWG series with Active status, offering superior long-term availability. Both maintain AEC-Q200 automotive qualification and are suitable for direct substitution.

Q: Are there height restrictions when substituting with upgraded voltage ratings?

A: The original EEE-FC0J680AP has maximum seated height of 5.40mm. Upgraded alternatives (EEE-HB1A680AP, EEE-FP1C680AP, EEE-FP1E680AP) have maximum seated height of 5.80mm. This 0.40mm increase must be evaluated against circuit board layout constraints, component clearances, and enclosure dimensions. Surface mount land size remains identical at 0.260" L x 0.260" W (6.60mm x 6.60mm) for all parts.

Q: Why do some substitutes have 2000-hour lifetime instead of 1000-hour?

A: Extended lifetime specifications (2000 hours at 105°C) represent improved component reliability and longevity. This is an upgrade parameter that does not affect electrical compatibility. Higher lifetime ratings indicate enhanced internal construction and materials, providing additional design margin for long-term applications. This parameter is not a limiting factor for substitution; higher lifetime is always acceptable.

Q: Is the Nichicon UWG0J680MCL1GB suitable for automotive applications?

A: Yes. The UWG0J680MCL1GB carries AEC-Q200 automotive qualification, identical to the original Panasonic part. It is suitable for automotive applications requiring 68 µF, 6.3 V aluminum electrolytic capacitors in surface mount radial can package. The part is ROHS3 compliant and maintains unlimited moisture sensitivity level (MSL 1).

Q: Can I use a higher capacitance value as a substitute?

A: No. Capacitance is a mandatory matching parameter. Only 68 µF parts are acceptable substitutes. Different capacitance values will alter circuit behavior, frequency response, and filtering characteristics, making them unsuitable for direct replacement.

Q: What is the significance of AEC-Q200 rating on these parts?

A: AEC-Q200 is the automotive electronics council qualification standard for passive components. All listed substitute parts carry this certification, confirming they meet automotive industry reliability, quality, and performance requirements. This rating is mandatory for automotive applications and ensures component suitability for vehicle electrical systems.
