Substitute Part Grouping Explanation

Substitution of the AFK226M80F24B-F is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance: 22 µF (exact match)
• Voltage Rating: 80 V (minimum requirement; higher ratings acceptable)
• Tolerance: ±20% (matching tolerance class)
• ESR: 1.3 Ohm @ 100 kHz (electrical performance indicator)
• Lifetime: 2000 Hrs @ 105°C (thermal endurance specification)
• Ripple Current Capability: 130 mA @ 100 kHz and 97.5 mA @ 120 Hz (current handling)

Mechanical Equivalence Requirements:

• Package Type: Radial, Can - SMD (surface mount configuration)
• Case Diameter: 8.00 mm (physical footprint)
• Height: 10.50 mm maximum seated height (PCB clearance)
• Mounting Type: Surface Mount (assembly compatibility)
• Polarization: Polar (circuit polarity requirement)

Compliance Requirements:

• AEC-Q200 automotive qualification
• RoHS3 compliance
• Operating temperature range: -55°C to 105°C

The substitute part EEE-FK1K220P from Panasonic Electronic Components meets all electrical and mechanical equivalence criteria and maintains full compliance with automotive and environmental standards.

Parameter Comparison

Engineering Selection Recommendations

The EEE-FK1K220P from Panasonic Electronic Components is a direct electrical and mechanical equivalent to the discontinued AFK226M80F24B-F. Selection of this substitute is based on the following engineering factors:

Electrical Compatibility: All critical electrical parameters match exactly, including capacitance, voltage rating, tolerance, ESR, lifetime rating, and ripple current specifications. The substitute maintains identical performance characteristics in bypass and decoupling applications.

Mechanical Compatibility: The substitute maintains identical case diameter (8.00 mm) and maximum seated height (10.50 mm), ensuring PCB footprint compatibility. Both components use surface mount radial can packaging.

Compliance and Certification: The EEE-FK1K220P carries AEC-Q200 automotive qualification and ROHS3 compliance, matching the original part's certification status. Both components operate across the identical temperature range of -55°C to 105°C.

Product Availability: The substitute is currently in active production status with 7889 pieces in stock, providing supply continuity for the discontinued AFK226M80F24B-F.

Minor Consideration: The surface mount land size differs slightly (8.30 mm x 8.30 mm for the substitute versus 8.30 mm x 10.00 mm for the original). This variation is within standard PCB design tolerances for surface mount aluminum electrolytic capacitors and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the EEE-FK1K220P be used as a direct replacement for the AFK226M80F24B-F without circuit modification?

A: Yes. The substitute part meets all electrical and mechanical specifications. Both components have identical capacitance (22 µF), voltage rating (80 V), ESR (1.3 Ohm @ 100 kHz), ripple current ratings, and operating temperature range. The physical dimensions are compatible with the original PCB layout.

Q: What is the significance of the surface mount land size difference?

A: The original part specifies 8.30 mm x 10.00 mm land size, while the substitute specifies 8.30 mm x 8.30 mm. This minor variation is within standard manufacturing tolerances for surface mount aluminum electrolytic capacitors and does not prevent proper solder joint formation or mechanical stability on the PCB.

Q: Are both parts qualified for automotive applications?

A: Yes. Both the AFK226M80F24B-F and EEE-FK1K220P carry AEC-Q200 qualification, confirming suitability for automotive-grade applications with specified reliability and performance standards.

Q: What is the difference in packaging between the two parts?

A: The original part is supplied in standard packaging, while the substitute (EEE-FK1K220P) is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume surface mount assembly and does not affect component performance or compatibility.

Q: Do both parts meet environmental compliance requirements?

A: Yes. Both the AFK226M80F24B-F and EEE-FK1K220P are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: Is the 2000-hour lifetime rating at 105°C sufficient for the application?

A: The 2000-hour lifetime rating at 105°C is a standard specification for aluminum electrolytic capacitors in this voltage and capacitance class. This rating applies to both the original and substitute parts and is appropriate for automotive bypass and decoupling applications operating within the specified temperature range.

Q: Can the substitute part be used in high-frequency ripple current applications?

A: Yes. The EEE-FK1K220P maintains the same ripple current rating as the original part: 130 mA @ 100 kHz and 97.5 mA @ 120 Hz. The substitute is suitable for applications requiring these ripple current specifications.
