Substitute Part Grouping Explanation

Substitution of the AFK107M2AP44B-F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 100 µF (exact match required)
• Voltage rating: 100 V (exact match required)
• Tolerance: ±20% (exact match required)
• Operating temperature range: -55°C to 105°C (exact match required)
• Lifetime specification: 5000 Hrs @ 105°C (exact match required)
• Ripple current ratings: 594.8 mA @ 120 Hz and 793 mA @ 100 kHz (exact match required)
• Impedance: 170 mOhms (exact match required)

Mechanical Parameters:

• Package type: Radial, Can - SMD (exact match required)
• Physical dimensions: 0.630" Dia (16.00mm), Height 0.669" (17.00mm) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Polarization: Polar (exact match required)

Compliance Parameters:

• AEC-Q200 automotive qualification (required for automotive applications)
• RoHS3 compliance (required for regulatory conformance)
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts must satisfy all electrical, mechanical, and compliance parameters to ensure functional and physical interchangeability without design modification.

Parameter Comparison

Engineering Selection Recommendations

Both Panasonic substitute parts, EEE-FK2A101AM and EEV-FK2A101M, are direct functional equivalents to the discontinued AFK107M2AP44B-F. Selection between these alternatives is based on the following criteria:

Product Availability and Supply Chain: Both substitute parts are currently active in production. EEV-FK2A101M has higher inventory availability (2220 Pcs) compared to EEE-FK2A101AM (1303 Pcs), providing greater supply chain flexibility for high-volume applications.

Compliance and Automotive Qualification: Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance, meeting the regulatory requirements of the original component. Both are suitable for automotive bypass and decoupling applications.

Application-Specific Considerations: EEE-FK2A101AM is specified for high-temperature reflow applications in addition to standard automotive use. EEV-FK2A101M is designated for general automotive applications. Selection should align with the specific manufacturing process and thermal profile requirements of the target application.

Physical and Electrical Interchangeability: Both substitute parts are physically and electrically identical to the original component across all critical parameters. PCB land pattern compatibility is confirmed for both alternatives, with surface mount land sizes of 0.669" L x 0.669" W (17.00mm x 17.00mm) for both Panasonic parts, compared to the original 0.669" L x 0.748" W (17.00mm x 19.00mm). This minor land pattern difference does not affect functional interchangeability on standard PCB designs.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK2A101AM and EEV-FK2A101M be used interchangeably with AFK107M2AP44B-F?

A: Yes. Both Panasonic parts are direct functional equivalents. They match all critical electrical parameters (capacitance, voltage, tolerance, temperature range, lifetime, ripple current, and impedance), physical dimensions, mounting type, and compliance certifications. No circuit design modifications are required.

Q: What is the difference between EEE-FK2A101AM and EEV-FK2A101M?

A: Both parts are electrically and mechanically identical. The primary difference is application designation: EEE-FK2A101AM is specified for high-temperature reflow processes, while EEV-FK2A101M is designated for general automotive applications. Selection should be based on manufacturing process requirements and thermal profile compatibility.

Q: Are there any PCB layout considerations when substituting these parts?

A: The original AFK107M2AP44B-F has a surface mount land size of 0.669" L x 0.748" W (17.00mm x 19.00mm). Both Panasonic substitutes have a land size of 0.669" L x 0.669" W (17.00mm x 17.00mm). This difference is minor and does not affect standard PCB designs. Verify land pattern compatibility with your specific PCB layout if custom footprints are used.

Q: Do both substitute parts meet automotive qualification requirements?

A: Yes. Both EEE-FK2A101AM and EEV-FK2A101M carry AEC-Q200 automotive qualification, matching the original component. Both are suitable for automotive bypass and decoupling applications.

Q: What is the moisture sensitivity level of the substitute parts?

A: Both substitute parts have a Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), identical to the original component. This indicates no moisture sensitivity restrictions for storage or handling.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both EEE-FK2A101AM and EEV-FK2A101M are ROHS3 compliant, matching the regulatory status of the original AFK107M2AP44B-F.

Q: Which substitute part should I select for new designs?

A: For new designs, either part is acceptable based on electrical and mechanical equivalence. EEV-FK2A101M is recommended for general automotive applications due to higher inventory availability. EEE-FK2A101AM is recommended if high-temperature reflow compatibility is a specific manufacturing requirement.
