337KXM025MLN Equivalent & Substitute Parts

Part Overview

The 337KXM025MLN is a 330 µF, 25 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the KXM series. This radial, through-hole component is designed for general-purpose applications with a rated lifetime of 4000 hours at 105°C. The part is currently active in production and ROHS3 compliant. Substitute parts are identified when original inventory is unavailable, when application requirements demand extended operational lifetime, or when alternative manufacturer sourcing is necessary for supply chain continuity.

The substitute part ELXZ250ELL331MJC5S from Chemi-Con meets all mandatory electrical, mechanical, and compliance requirements. This part maintains identical capacitance, voltage rating, tolerance, package geometry, and lead spacing. The substitute offers an extended lifetime rating of 5000 hours at 105°C compared to the original 4000 hours, and includes AEC-Q200 automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

The ELXZ250ELL331MJC5S is a direct electrical and mechanical substitute for the 337KXM025MLN. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across applications.

Selection Criteria:

The substitute part is appropriate for applications requiring extended operational lifetime. The ELXZ250ELL331MJC5S provides 5000 hours at 105°C versus 4000 hours for the original part, representing a 25% increase in rated lifetime. The substitute also carries AEC-Q200 automotive qualification, making it suitable for automotive-grade applications where the original general-purpose rating may be insufficient.

Both parts operate across the identical temperature range of -55°C to 105°C and maintain the same physical footprint, ensuring direct board-level compatibility without layout modifications.

The substitute exhibits lower impedance (90 mOhms versus 170 mOhms), which may provide improved high-frequency performance characteristics in applications sensitive to impedance response.

Frequently Asked Questions (FAQ)

Q: Can the ELXZ250ELL331MJC5S replace the 337KXM025MLN in existing designs without PCB modification?

A: Yes. Both parts share identical lead spacing (0.197" / 5.00mm), case diameter (0.394" / 10.00mm), and seated height (0.551" / 14.00mm). The radial, through-hole package geometry is identical, permitting direct substitution without PCB layout changes.

Q: What are the electrical differences between these two parts?

A: Both parts provide 330 µF capacitance at 25 V with ±20% tolerance. The substitute offers lower impedance (90 mOhms versus 170 mOhms) and extended lifetime (5000 hours versus 4000 hours at 105°C). Ripple current ratings differ: the original supports 515 mA at 120 Hz and 1.03 A at 100 kHz, while the substitute supports 380 mA at 120 Hz and 760 mA at 100 kHz.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the 337KXM025MLN and ELXZ250ELL331MJC5S are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: What is the primary advantage of selecting the substitute part?

A: The ELXZ250ELL331MJC5S provides extended operational lifetime (5000 hours at 105°C) and AEC-Q200 automotive qualification. These characteristics make it suitable for applications requiring higher reliability standards or automotive-grade component specifications.

Q: Do both parts operate across the same temperature range?

A: Yes. Both parts operate from -55°C to 105°C, ensuring thermal compatibility across standard industrial and commercial temperature specifications.

Q: Is the substitute part available in the same packaging format?

A: Yes. The ELXZ250ELL331MJC5S is supplied in bulk packaging as a radial, through-hole aluminum electrolytic capacitor, maintaining the same physical form factor as the original 337KXM025MLN.
