Substitute Part Grouping Explanation

Substitution eligibility for the EEV-FK1K331M is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 80 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: Radial, Can - SMD (exact match required)
• Physical dimensions: 0.630" Dia × 0.669" H (exact match required)
• Mounting type: Surface Mount (exact match required)
• Polarization: Polar (exact match required)
• Lifetime rating: 5000 Hrs @ 105°C (exact match required)
• Operating temperature range: -55°C ~ 105°C (exact match required)
• RoHS3 compliance: Required
• AEC-Q200 automotive rating: Required

The substitute part EEE-FK1K331AM meets all electrical and mechanical equivalence criteria and maintains full compliance with automotive and environmental standards.

Parameter Comparison

Engineering Selection Recommendations

Both EEV-FK1K331M and EEE-FK1K331AM are active production parts from Panasonic Electronic Components with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain requirements rather than technical differentiation. Both parts carry AEC-Q200 automotive qualification and full RoHS3 compliance, making them suitable for automotive applications requiring high-reliability aluminum electrolytic capacitors. The EEE-FK1K331AM includes high temperature reflow capability in its application profile, which may be relevant for specific manufacturing processes. Part selection should be determined by inventory availability, lead time requirements, and procurement preferences.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK1K331AM be used as a direct replacement for EEV-FK1K331M?

A: Yes. Both parts are electrically and mechanically equivalent with identical capacitance (330 µF), voltage rating (80 V), tolerance (±20%), physical dimensions (0.630" Dia × 0.669" H), and performance characteristics. They share the same surface mount land pattern and mounting requirements.

Q: Are there any differences in automotive compliance between these parts?

A: No. Both parts carry AEC-Q200 qualification and are approved for automotive applications. Both maintain RoHS3 compliance and unlimited moisture sensitivity level rating.

Q: What is the significance of the different part number prefixes (EEV vs. EEE)?

A: The part number prefix indicates different product lines within Panasonic's FK series aluminum electrolytic capacitors. Both prefixes denote equivalent performance within the specified parameters.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. The identical surface mount land size (0.669" L × 0.669" W) and mounting type ensure direct PCB compatibility without layout modifications.

Q: Are the ripple current ratings identical?

A: Yes. Both parts are rated for 594.8 mA ripple current at 120 Hz and 793 mA at 100 kHz, with identical impedance of 170 mOhms.
