Key Parameters

Substitute Part Grouping Explanation

Substitution for the AFK226M2AF24B-F is determined by strict matching of the following critical parameters:

• Electrical Parameters: Capacitance (22 µF), voltage rating (100 V), and tolerance (±20%)
• Environmental Ratings: Operating temperature range (-55°C to 105°C) and lifetime specification (2000 Hrs @ 105°C)
• Mechanical Compatibility: Package type (Radial, Can - SMD), physical dimensions, and surface mount mounting
• Compliance Requirements: AEC-Q200 automotive qualification and ROHS3 status

The identified substitute, EEE-FK2A220P from Panasonic Electronic Components, meets all these critical parameters, enabling direct functional replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The EEE-FK2A220P is the qualified substitute for the discontinued AFK226M2AF24B-F. Both components share identical electrical specifications, mechanical dimensions, and compliance certifications (AEC-Q200, ROHS3). The Panasonic part maintains active production status with documented inventory availability, ensuring supply chain continuity for new builds and repairs.

The EEE-FK2A220P is shipped in Tape & Reel (TR) packaging, whereas packaging information for the original part was not specified. Both components are suitable for automotive, bypass, and decoupling applications within the specified electrical and thermal parameters.

Frequently Asked Questions (FAQ)

Can I use EEE-FK2A220P as a direct replacement for AFK226M2AF24B-F? Yes. Both components share identical capacitance (22 µF), voltage rating (100 V), tolerance (±20%), physical dimensions (8.00mm diameter × 10.50mm height), operating temperature range (-55°C to 105°C), and lifetime rating (2000 Hrs @ 105°C). Both hold AEC-Q200 and ROHS3 certification.

Are there footprint compatibility concerns? The physical dimensions and land size patterns are matched for direct PCB assembly compatibility. The Panasonic part specifies surface mount land size as 0.327" L × 0.327" W (8.30mm × 8.30mm), while the original part lists 0.327" L × 0.394" W (8.30mm × 10.00mm). Verify land pattern dimensions against your PCB layout.

What is the difference in ripple current rating? Both components are specified at 97.5 mA @ 120 Hz and 130 mA @ 100 kHz, indicating equivalent performance in high-frequency applications.

Does the ESR specification differ between parts? The AFK226M2AF24B-F specifies ESR of 1.3 Ohm @ 100 kHz. The EEE-FK2A220P does not provide explicit ESR specification in the available data; the impedance is listed as 1.3 Ohms for matching thermal and performance characteristics.

Is the Tape & Reel packaging compatible with my assembly process? Tape & Reel packaging is standard for surface mount component handling in automated assembly environments. Verify compatibility with your specific pick-and-place equipment and tape specifications.
