Substitute Part Grouping Explanation

Substitution of the AFK338M06H32B-F is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance: 3300 µF (exact match required)
• Voltage Rating: 6.3 V (exact match required)
• Tolerance: ±20% (exact match required)
• Impedance: 60 mOhms (exact match required)
• Ripple Current Ratings: 825 mA @ 120 Hz and 1.1 A @ 100 kHz (exact match required)
• Lifetime: 5000 Hrs @ 105°C (exact match required)
• Operating Temperature: -55°C ~ 105°C (exact match required)
• Polarization: Polar (exact match required)

Mechanical Equivalence Criteria:

• Package Type: Radial, Can - SMD (exact match required)
• Physical Diameter: 12.50 mm (exact match required)
• Physical Height: 14.00 mm (exact match required)
• Mounting Type: Surface Mount (exact match required)

Compliance Criteria:

• AEC-Q200 Automotive Rating (required for automotive applications)
• RoHS3 Compliance (required for regulatory alignment)

The identified substitute parts meet all electrical and mechanical parameters specified for the main part. Packaging format differences (Tape & Reel vs. alternative formats) do not affect functional equivalence.

Engineering Selection Recommendations

Both EEE-FK0J332AQ and EEV-FK0J332Q from Panasonic Electronic Components are direct functional equivalents to the discontinued AFK338M06H32B-F. Selection between these alternatives is based on the following factors:

Product Status: Both substitute parts are active products with confirmed inventory availability, ensuring long-term supply chain continuity compared to the discontinued CDE part.

Compliance and Certifications: All three parts maintain AEC-Q200 automotive qualification and RoHS3 compliance, meeting regulatory requirements for automotive and industrial applications.

Electrical Performance: The substitute parts deliver identical electrical characteristics across all specified parameters, including capacitance, voltage rating, ESR, ripple current ratings, and thermal lifetime.

Mechanical Compatibility: Both Panasonic alternatives maintain identical physical dimensions (12.50 mm diameter, 14.00 mm height) and surface mount package configuration, ensuring direct PCB footprint compatibility.

Packaging Consideration: Both substitute parts are supplied in Tape & Reel format. If alternative packaging formats are required for specific assembly processes, this should be verified with the component supplier.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK0J332AQ or EEV-FK0J332Q be used as direct replacements for AFK338M06H32B-F without PCB redesign?

A: Yes. Both Panasonic parts are mechanically and electrically equivalent. They share identical physical dimensions (12.50 mm diameter, 14.00 mm height), surface mount package configuration, and all electrical specifications. No PCB layout modifications are required.

Q: What is the difference between EEE-FK0J332AQ and EEV-FK0J332Q?

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The difference lies in the series designation (FK vs. EV-FK) and internal product line classification within Panasonic. Both are active products with AEC-Q200 qualification. Selection between them depends on supplier availability and internal procurement preferences.

Q: Are the substitute parts suitable for automotive applications?

A: Yes. Both EEE-FK0J332AQ and EEV-FK0J332Q carry AEC-Q200 automotive qualification, matching the original AFK338M06H32B-F. They are approved for automotive bypass and decoupling applications across the specified operating temperature range of -55°C to 105°C.

Q: What is the significance of the 60 mOhms ESR specification?

A: The 60 mOhms ESR at 100 kHz is a critical electrical parameter that determines the capacitor's impedance and ripple current handling capability. All three parts (original and substitutes) maintain this specification, ensuring equivalent performance in power supply filtering and decoupling circuits.

Q: Are there any differences in the surface mount land size between the main part and substitutes?

A: The AFK338M06H32B-F specifies a surface mount land size of 0.531" L x 0.590" W (13.50 mm x 15.00 mm). Both Panasonic substitutes specify 0.531" L x 0.531" W (13.50 mm x 13.50 mm). This represents a minor variation in the pad width dimension. Verify PCB land pattern compatibility with your specific design before implementation.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special desiccant or humidity control requirements.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are RoHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
