AVS337M25F24T-F Equivalent & Substitute Parts

Part Overview

The AVS337M25F24T-F is a 330 µF, 25 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in the AVS series. This surface mount radial can capacitor is designed for automotive, bypass, and decoupling applications with AEC-Q200 qualification. The part operates across -40°C to 85°C with a rated lifetime of 2000 hours at 85°C and features 800 mOhm equivalent series resistance at 120 Hz.

The AVS337M25F24T-F carries a "Not For New Designs" product status, indicating that Cornell Dubilier has discontinued this model for new applications. Engineers and procurement teams must identify functionally equivalent alternatives that maintain the same electrical performance envelope while utilizing active or upgraded product lines.

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

The EDK337M025S9MAA (KEMET) provides direct substitution with active product status and AEC-Q200 qualification. This part maintains the same capacitance, voltage rating, operating temperature range (-40°C to 85°C), and lifetime specification (2000 Hrs @ 85°C) as the AVS337M25F24T-F. The land size (8.30 × 8.30 mm) and case diameter (8.00 mm) are identical, requiring no PCB layout modifications. KEMET's EDK series is actively manufactured and supported.

For Upgraded Performance (Extended Temperature and Lifetime):

The AFK337M25F24T-F (CDE) is the direct upgrade path from the same manufacturer. This part is active and maintains CDE's product continuity. It offers:

Extended operating temperature range: -55°C to 105°C (versus -40°C to 85°C)
Extended lifetime: 2000 Hrs @ 105°C (versus 2000 Hrs @ 85°C)
Significantly reduced ESR: 160 mOhm @ 100 kHz (versus 800 mOhm @ 120 Hz)
Increased ripple current capacity: 450 mA @ 120 Hz and 600 mA @ 100 kHz

The AFK337M25F24T-F requires PCB land size adjustment from 8.30 × 8.30 mm to 8.30 × 10.00 mm and height clearance verification (10.50 mm versus 10.20 mm). AEC-Q200 qualification is maintained.

For Multi-Source Automotive Applications:

The 25TKV330M8X10.5 (Rubycon) and 25TLV330M8X10.5 (Rubycon) provide AEC-Q200 qualified alternatives with active product status. Both feature:

Extended operating temperature range: -55°C to 105°C
Extended lifetime: 2000 Hrs @ 105°C (TKV) or 5000 Hrs @ 105°C (TLV)
Identical case diameter and land size: 8.00 mm and 8.30 × 8.30 mm
Height: 10.50 mm (requires clearance verification)

The 25TKV330M8X10.5 offers the lowest ESR at 80 mOhm @ 100 kHz and highest ripple current capacity (510 mA @ 120 Hz, 850 mA @ 100 kHz). The 25TLV330M8X10.5 provides the longest lifetime rating at 5000 Hrs @ 105°C for applications requiring extended reliability.

For High-Volume Availability:

The EEE-FK1E331P (Panasonic) offers the largest inventory (83,030 pieces) with active product status and AEC-Q200 qualification. This part provides:

Extended operating temperature range: -55°C to 105°C
Extended lifetime: 2000 Hrs @ 105°C
Identical case diameter and land size: 8.00 mm and 8.30 × 8.30 mm
Height: 10.50 mm (requires clearance verification)
Ripple current capacity: 450 mA @ 120 Hz, 600 mA @ 100 kHz

Parts Not Recommended for New Designs:

The AVE337M25G24T-F (CDE) carries obsolete status and features a larger case diameter (10.00 mm) and different land size (10.40 × 10.40 mm), requiring significant PCB redesign. The EMVA250ARA331MHA0G (Chemi-Con) is designated Last Time Buy with no AEC-Q200 qualification and a different land size (8.30 × 8.30 mm but larger case diameter of 10.00 mm). The 337AXZ025M (CDE / Illinois Capacitor) lacks AEC-Q200 qualification despite active status.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different case diameter?

A: Case diameter changes require mechanical clearance verification on the PCB. The AVS337M25F24T-F uses an 8.00 mm diameter case. Substitutes with 10.00 mm diameter (such as AVE337M25G24T-F) require confirmation that board-level clearance exists. All recommended upgrades maintain the 8.00 mm diameter, eliminating this concern.

Q: What is the impact of different land sizes on PCB compatibility?

A: The AVS337M25F24T-F specifies 8.30 × 8.30 mm land size. Most recommended substitutes maintain this footprint. The AFK337M25F24T-F requires 8.30 × 10.00 mm land size, which is compatible with standard reflow processes but requires PCB layout adjustment. Verify your PCB design tool supports the modified land pattern before committing to this substitute.

Q: Why do some substitute parts have "Not Specified" ESR values?

A: ESR specifications are provided by manufacturers when this parameter is critical for the application. Parts with unspecified ESR have been tested to meet ripple current and thermal performance requirements but may not publish detailed impedance curves. For applications where ESR is critical (such as high-frequency switching supplies), select parts with published ESR values: AFK337M25F24T-F (160 mOhm @ 100 kHz) or 25TKV330M8X10.5 (80 mOhm @ 100 kHz).

Q: Is AEC-Q200 qualification mandatory for my application?

A: AEC-Q200 qualification is mandatory for automotive applications and strongly recommended for industrial and consumer applications requiring reliability assurance. The AVS337M25F24T-F carries AEC-Q200 qualification. Recommended substitutes with AEC-Q200 include: AFK337M25F24T-F, EDK337M025S9MAA, 25JZV330M8X10.5, 25TKV330M8X10.5, 25TLV330M8X10.5, and EEE-FK1E331P. The 337AXZ025M and AVE337M25G24T-F lack this qualification.

Q: What is the difference between "Active," "Obsolete," and "Last Time Buy" product status?

A: Active status indicates the manufacturer continues production and supports the part for new designs. Obsolete status indicates the manufacturer has discontinued production and no longer accepts new orders; existing inventory may be available from distributors but supply is finite. Last Time Buy status indicates the manufacturer has announced discontinuation and offers a final purchase window before production ends. For new designs, select only Active status parts to ensure long-term supply chain stability.

Q: Can I substitute a part with extended temperature range (-55°C to 105°C) in an application rated for -40°C to 85°C?

A: Yes. Extended temperature range parts are backward compatible with applications requiring narrower ranges. The extended range provides design margin and future flexibility. All recommended upgrades feature -55°C to 105°C operating range, making them suitable for the original -40°C to 85°C requirement.

Q: What does "2000 Hrs @ 85°C" lifetime specification mean?

A: This specification indicates the capacitor is rated to maintain its electrical characteristics (capacitance, ESR, leakage current) for 2000 hours of continuous operation at 85°C ambient temperature. At lower temperatures, lifetime extends significantly. Upgrades offering "2000 Hrs @ 105°C" or "5000 Hrs @ 105°C" provide superior reliability margins, particularly in high-temperature environments or applications with thermal cycling.

Q: Why is ripple current capacity important for substitution?

A: Ripple current capacity determines the maximum AC current the capacitor can handle without exceeding temperature limits. The AVS337M25F24T-F specifies 150 mA @ 120 Hz and 255 mA @ 10 kHz. Substitutes with higher ripple current ratings (such as 25TKV330M8X10.5 at 510 mA @ 120 Hz and 850 mA @ 100 kHz) provide design margin for applications with high AC stress. For direct replacement, ensure the substitute meets or exceeds the original ripple current specification.

Q: Is ROHS3 compliance required?

A: ROHS3 compliance is mandatory for products sold in the European Union and increasingly required by global OEMs. All recommended substitutes are ROHS3 compliant, matching the AVS337M25F24T-F specification. Verify ROHS3 status with your supplier before finalizing procurement.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. The capacitor can be stored and handled without special humidity controls. All recommended substitutes maintain MSL 1 classification, eliminating moisture management concerns during assembly.
