Engineering Selection Recommendations

For Direct 10 V Replacement (Same Voltage Rating):

The EEE-FK1A331GP (Panasonic Electronic Components) is the primary recommended direct substitute. This part maintains identical electrical specifications to the AVRF337M10F24T-F, including 160 mOhm ESR at 100 kHz, 600 mA ripple current at 100 kHz, and 5000 hours lifetime at 105°C. The EEE-FK1A331GP carries AEC-Q200 automotive qualification and active product status with 1635 units in stock.

The UCD1A331MNL1GS (Nichicon) provides an alternative direct substitute with matching electrical parameters and AEC-Q200 qualification. This part is suitable for automotive applications and maintains 5000 hours lifetime at 105°C.

The AFK337M10F24T-F (Cornell Dubilier Electronics) offers a same-manufacturer alternative from the active product line. This part carries AEC-Q200 qualification but features a reduced lifetime of 2000 hours at 105°C, making it suitable for applications with less stringent thermal endurance requirements.

The 865060253007 (Würth Elektronik) provides a direct voltage substitute with 5000 hours lifetime. This part features slightly elevated ESR of 170 mOhm and reduced ripple current of 500 mA at 100 kHz, requiring verification for applications with high ripple current demands.

For Voltage-Upgraded Replacement (Higher Voltage Ratings):

The EEE-FK1E331GP (Panasonic Electronic Components, 25 V rating) and EEE-FK1C331GP (Panasonic Electronic Components, 16 V rating) are recommended upgrade substitutes. Both parts maintain 160 mOhm ESR, 600 mA ripple current at 100 kHz, and 5000 hours lifetime at 105°C. These parts carry AEC-Q200 qualification and are suitable for applications requiring enhanced voltage margin.

The EEE-FT1V331GP (Panasonic Electronic Components, 35 V rating) provides maximum voltage headroom with improved ESR of 80 mOhm and elevated ripple current capability of 850 mA at 100 kHz. This part is recommended for applications with demanding ripple current specifications or requiring maximum voltage safety margin.

The 25TLV330M8X10.5 (Rubycon, 25 V rating) and 865060453008 (Würth Elektronik, 25 V rating) provide alternative 25 V upgrade options with 5000 hours lifetime at 105°C. The Rubycon part carries AEC-Q200 qualification, while the Würth part does not.

Frequently Asked Questions (FAQ)

Q: Can the AFK337M10F24T-F be used as a direct replacement for the AVRF337M10F24T-F?

A: The AFK337M10F24T-F is electrically compatible as a direct substitute, maintaining identical capacitance, voltage rating, tolerance, and ESR specifications. However, the AFK337M10F24T-F has a reduced lifetime of 2000 hours at 105°C compared to the original 5000 hours. This part is suitable for applications where thermal endurance requirements are less stringent. Both parts are from Cornell Dubilier Electronics and share the same physical dimensions.

Q: What is the difference between direct substitutes and upgrade substitutes?

A: Direct substitutes maintain the same 10 V voltage rating as the AVRF337M10F24T-F and are electrically interchangeable without circuit modification. Upgrade substitutes increase the voltage rating to 16 V, 25 V, or 35 V while maintaining the same capacitance and physical form factor. Upgrade substitutes are backward compatible in applications where the original 10 V rating is sufficient, providing enhanced voltage margin and improved performance characteristics in some cases.

Q: Are all substitute parts compatible with the original PCB layout?

A: All listed substitute parts maintain the same physical diameter of 8.00 mm and surface mount land size of 8.30 mm × 8.30 mm, ensuring PCB footprint compatibility. Maximum height varies between 10.20 mm (original part) and 10.50 mm (substitute parts). Verify available clearance above the component location to confirm mechanical fit. All parts are surface mount radial can packages with identical mounting type.

Q: Which substitute part is recommended for automotive applications?

A: For automotive applications, select parts carrying AEC-Q200 qualification: EEE-FK1A331GP (10 V), UCD1A331MNL1GS (10 V), 25TLV330M8X10.5 (25 V), EEE-FK1C331GP (16 V), EEE-FK1E331GP (25 V), or EEE-FT1V331GP (35 V). The EEE-FK1A331GP is the primary recommended direct substitute for automotive applications, maintaining identical electrical specifications and carrying active product status.

Q: What is the significance of ESR (Equivalent Series Resistance) in capacitor selection?

A: ESR affects capacitor performance in high-frequency applications and ripple current handling. The AVRF337M10F24T-F specifies 160 mOhm ESR at 100 kHz. Most recommended substitutes maintain this specification. The 865060253007 (Würth Elektronik) features 170 mOhm ESR, which is slightly elevated. The EEE-FT1V331GP features reduced ESR of 80 mOhm, providing improved performance in ripple current applications. Select parts based on application ripple current requirements and frequency characteristics.

Q: Can the AVRF337M10F24T-F be replaced with a higher voltage rated part in the same circuit?

A: Yes, higher voltage rated parts (16 V, 25 V, or 35 V) are backward compatible in applications where the original 10 V rating is sufficient. The circuit will operate correctly with the higher voltage rated capacitor. Upgrade substitutes provide enhanced voltage margin and improved safety characteristics. However, verify that the application does not require the specific electrical characteristics of the original 10 V part before implementing a voltage upgrade.

Q: What is the difference between the Panasonic FK and FT series?

A: The Panasonic FK series (EEE-FK1A331GP, EEE-FK1C331GP, EEE-FK1E331GP) maintains 160 mOhm ESR across all voltage ratings and provides 600 mA ripple current at 100 kHz. The Panasonic FT series (EEE-FT1V331GP) features reduced ESR of 80 mOhm and elevated ripple current capability of 850 mA at 100 kHz at 35 V rating. Both series carry AEC-Q200 qualification and 5000 hours lifetime at 105°C. Select the FT series for applications requiring superior ripple current handling or lower ESR performance.

Q: Is the AVRF337M10F24T-F still available for purchase?

A: The AVRF337M10F24T-F is classified as obsolete, indicating discontinued production. However, 858 units are currently in stock. For long-term supply chain reliability, transition to an active product substitute such as EEE-FK1A331GP, UCD1A331MNL1GS, or AFK337M10F24T-F to ensure continued availability and support.

Q: What packaging format is used for these capacitors?

A: The AVRF337M10F24T-F is supplied in Tape & Reel (TR) packaging for automated assembly. All listed substitute parts are also available in Tape & Reel format, ensuring compatibility with standard surface mount assembly processes. The surface mount land size is 8.30 mm × 8.30 mm for all parts, maintaining consistent pick-and-place equipment compatibility.
