Substitute Part Grouping Explanation

Substitution eligibility for the AFK477M63P44B-F is determined by strict equivalence across the following parameters:

Electrical Equivalence Requirements:

• Capacitance: 470 µF (exact match)
• Voltage Rating: 63 V (exact match)
• Tolerance: ±20% (exact match acceptable)
• Operating Temperature Range: -55°C ~ 105°C (substitute must support full range)
• Lifetime @ 105°C: 5000 Hrs (substitute must meet or exceed)
• Ripple Current @ 100 kHz: 1.41 A (substitute must meet or exceed)
• Impedance: 82 mOhms (substitute must meet or be lower)

Mechanical Equivalence Requirements:

• Package Type: Radial, Can - SMD (exact match)
• Diameter: 0.630" (16.00mm) (exact match)
• Height: 0.669" (17.00mm) (exact match)
• Mounting Type: Surface Mount (exact match)

Compliance Requirements:

• AEC-Q200 Automotive Rating (required for automotive applications)
• RoHS3 Compliance (required for environmental regulation)

Substitute parts must satisfy all electrical, mechanical, and compliance criteria to ensure direct interchangeability without circuit redesign or PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

Frequently Asked Questions (FAQ)

Q: Can EEE-FK1J471AM or EEV-FK1J471M be used as direct replacements for AFK477M63P44B-F without circuit modification?

A: Yes. Both Panasonic parts are electrically and mechanically equivalent. They share identical capacitance (470 µF), voltage rating (63 V), tolerance (±20%), operating temperature range (-55°C ~ 105°C), lifetime rating (5000 Hrs @ 105°C), ripple current specifications (1.41 A @ 100 kHz), impedance (82 mOhms), and physical dimensions (0.630" diameter, 0.669" height). No circuit redesign is required.

Q: What is the difference between EEE-FK1J471AM and EEV-FK1J471M?

A: The primary difference is packaging format. EEE-FK1J471AM is supplied in Tape & Reel (TR) configuration, optimized for automated assembly in high-volume production. EEV-FK1J471M is supplied in Cut Tape (CT) and Digi-Reel® formats, offering flexibility for both prototype and production quantities. Electrical specifications and physical dimensions are identical.

Q: Are both substitute parts AEC-Q200 qualified?

A: Yes. Both EEE-FK1J471AM and EEV-FK1J471M carry AEC-Q200 automotive qualification, meeting the same reliability and qualification standards as the original AFK477M63P44B-F.

Q: Will the substitute parts fit the existing PCB layout designed for AFK477M63P44B-F?

A: The physical dimensions (0.630" diameter, 0.669" height) are identical, ensuring mechanical fit. However, note that the surface mount land size differs slightly: the original part specifies 0.669" L x 0.748" W, while both Panasonic substitutes specify 0.669" L x 0.669" W. Verify PCB land pattern compatibility with your design specifications.

Q: What is the inventory status of these substitute parts?

A: EEE-FK1J471AM has 11,036 pcs in stock. EEV-FK1J471M has 1,000,200 pcs in stock. Both are active products with established supply chains.

Q: Are both substitute parts RoHS3 compliant?

A: Yes. Both EEE-FK1J471AM and EEV-FK1J471M are RoHS3 compliant, maintaining environmental regulation compliance equivalent to the original part.
