Substitute Part Grouping Explanation

Substitution eligibility for the EEE-FP1C681AV is determined by strict equivalence across the following parameters:

• Capacitance value: 680 µF (exact match required)
• Voltage rating: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: Radial, Can - SMD (exact match required)
• Physical dimensions: 0.394" Dia (10.00mm), Height 0.425" (10.80mm) (exact match required)
• Surface mount land size: 0.406" L x 0.406" W (10.30mm x 10.30mm) (exact match required)
• Operating temperature range: -55°C ~ 105°C (exact match required)
• Lifetime specification: 2000 Hrs @ 105°C (exact match required)
• Compliance: AEC-Q200, ROHS3 Compliant (exact match required)

The EEE-FK1C681AV meets all substitution criteria. Variations in ESR (Equivalent Series Resistance) and ripple current ratings do not disqualify substitution when all primary electrical and mechanical parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

Both the EEE-FP1C681AV and EEE-FK1C681AV are active production parts from Panasonic Electronic Components with identical AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on circuit-specific ripple current requirements and ESR performance characteristics. The EEE-FP1C681AV provides lower ESR (60 mOhm) and higher ripple current handling (1.19 A @ 100 kHz), while the EEE-FK1C681AV offers alternative performance characteristics within the same package and electrical specification envelope. Both parts satisfy identical mechanical fit and thermal operating requirements for surface mount assembly.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK1C681AV replace EEE-FP1C681AV in existing designs?

A: Yes. Both parts share identical capacitance (680 µF), voltage rating (16 V), tolerance (±20%), package type (Radial, Can - SMD), physical dimensions, surface mount land size, operating temperature range (-55°C ~ 105°C), lifetime specification (2000 Hrs @ 105°C), and AEC-Q200 qualification. Substitution is valid from an electrical and mechanical compatibility standpoint.

Q: What are the differences between these parts?

A: The primary differences are ESR and ripple current ratings. The EEE-FP1C681AV has 60 mOhm ESR and 1.19 A ripple current at 100 kHz. The EEE-FK1C681AV has 80 mOhm ESR and 850 mA ripple current at 100 kHz. These differences reflect different internal construction within the same external package.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts carry AEC-Q200 qualification and are rated for automotive and high-temperature reflow applications with identical operating temperature ranges and lifetime specifications.

Q: Do these parts have the same footprint?

A: Yes. Both parts have identical physical dimensions (0.394" Dia / 10.00mm), height (0.425" / 10.80mm), and surface mount land size (0.406" L x 0.406" W / 10.30mm x 10.30mm). PCB layout compatibility is maintained.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
