Parameter Comparison

Engineering Selection Recommendations

Both substitute parts—EEE-FK2A101AM and EEV-FK2A101M from Panasonic Electronic Components—provide direct functional and mechanical equivalence to the AFK107M2AP44T-F.

Selection Basis:

All three parts maintain identical electrical specifications across capacitance, voltage rating, tolerance, impedance, and ripple current parameters. Physical dimensions are equivalent, ensuring PCB layout compatibility without redesign. All parts carry AEC-Q200 automotive qualification and RoHS3 compliance, meeting regulatory and reliability requirements for automotive bypass and decoupling applications.

The substitute parts are manufactured by Panasonic Electronic Components, an established supplier of aluminum electrolytic capacitors with equivalent quality and reliability standards. Product status is active for all three parts, ensuring continued availability and supply chain stability.

Selection between the two Panasonic substitutes may be determined by inventory availability, lead time, or specific application requirements within the automotive domain. Both parts are functionally interchangeable with the primary CDE part.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK2A101AM or EEV-FK2A101M be used as direct replacements for AFK107M2AP44T-F without circuit modification?

A: Yes. Both Panasonic parts are direct substitutes. All critical electrical parameters—capacitance, voltage rating, tolerance, impedance, and ripple current—are identical. Physical dimensions and package type match exactly, eliminating the need for PCB layout changes or circuit redesign.

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

A: The AFK107M2AP44T-F specifies a surface mount land size of 0.669" L × 0.748" W (17.00 mm × 19.00 mm). Both Panasonic substitutes specify 0.669" L × 0.669" W (17.00 mm × 17.00 mm). This difference in land pattern width should be verified against your PCB design to ensure compatibility with existing footprints.

Q: Do all three parts meet automotive qualification requirements?

A: Yes. The AFK107M2AP44T-F, EEE-FK2A101AM, and EEV-FK2A101M all carry AEC-Q200 rating, confirming suitability for automotive applications. All parts are RoHS3 compliant and REACH unaffected.

Q: What is the significance of the 5000-hour lifetime rating at 105°C?

A: The 5000-hour lifetime at 105°C indicates the expected operational life under maximum rated temperature conditions. All three parts share this specification, ensuring equivalent reliability and service life in thermal stress scenarios typical of automotive environments.

Q: Are there any differences in ESR (Equivalent Series Resistance) specifications?

A: The AFK107M2AP44T-F specifies 170 mOhm ESR @ 100 kHz. The Panasonic substitutes do not list ESR values in their specifications but specify identical impedance of 170 mOhms, which is the functional equivalent parameter for this application.

Q: What is Moisture Sensitivity Level 1, and why is it important?

A: Moisture Sensitivity Level 1 indicates unlimited shelf life without special moisture control requirements. All three parts carry MSL 1 rating, meaning they can be stored and handled under standard conditions without desiccant packaging or time-limited exposure windows.

Q: Can these parts be used interchangeably in high-frequency ripple current applications?

A: Yes. All three parts support identical ripple current specifications: 594.8 mA @ 120 Hz and 793 mA @ 100 kHz. This ensures equivalent thermal performance and reliability in applications with significant AC current stress.
