Substitute Part Grouping Explanation

Substitution eligibility for the 228KXM025M is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 2200 µF (exact match required)
• Voltage Rating: 25 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead Spacing: 0.197" (5.00mm) (exact match required)
• Physical Dimensions: 0.492" Dia (12.50mm) (exact match required)
• Operating Temperature Range: -55°C to 105°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

Performance Parameters (Secondary Consideration):

• Lifetime @ Temperature
• ESR (Equivalent Series Resistance)
• Ripple Current ratings
• Impedance

The substitute part ELXZ250ELL222MK35S meets all mandatory matching parameters and is therefore qualified as an equivalent substitute.

Engineering Selection Recommendations

Primary Part: 228KXM025M

The 228KXM025M remains the primary selection for general-purpose applications. This part is active in production with confirmed inventory of 865 pieces. It is ROHS3 compliant and suitable for applications requiring the specified ripple current performance at both low and high frequencies.

Substitute Part: ELXZ250ELL222MK35S

The ELXZ250ELL222MK35S is qualified as an equivalent substitute based on full compliance with all mandatory electrical and mechanical parameters. This Chemi-Con component offers extended lifetime performance (7000 hours at 105°C versus 5000 hours) and lower impedance (22 mOhms versus 39 mOhms). The substitute part carries AEC-Q200 automotive qualification and is ROHS3 compliant. Physical compatibility is confirmed with a maximum seated height of 1.437" (36.50mm) compared to 1.457" (37.00mm) for the primary part, representing a 0.02" reduction that remains within typical PCB layout tolerances.

Selection between these parts should be based on application-specific requirements for ripple current handling and thermal lifetime expectations. The substitute part is suitable for applications where extended operational life at elevated temperature or reduced impedance characteristics provide design advantages.

Frequently Asked Questions (FAQ)

Q: Can ELXZ250ELL222MK35S be used as a direct replacement for 228KXM025M on existing PCBs?

A: Yes. Both parts share identical lead spacing (0.197" / 5.00mm), identical diameter (0.492" / 12.50mm), and compatible seated heights (difference of 0.02"). Through-hole mounting footprints are identical. No PCB redesign is required.

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

A: The primary differences are: (1) Lifetime at 105°C: 228KXM025M provides 5000 hours; ELXZ250ELL222MK35S provides 7000 hours; (2) Impedance: 228KXM025M is 39 mOhms; ELXZ250ELL222MK35S is 22 mOhms; (3) Ripple current capacity: 228KXM025M provides higher ripple current ratings at both 120 Hz and 100 kHz; (4) Manufacturer: Cornell Dubilier versus Chemi-Con; (5) Ratings: ELXZ250ELL222MK35S carries AEC-Q200 automotive qualification.

Q: Are both parts RoHS compliant?

A: Yes. Both 228KXM025M and ELXZ250ELL222MK35S are ROHS3 compliant and REACH unaffected.

Q: Which part should be selected for high ripple current applications?

A: The 228KXM025M provides superior ripple current performance with 2.55 A at 120 Hz and 3.4 A at 100 kHz, compared to 1.8825 A and 2.51 A respectively for the ELXZ250ELL222MK35S. For applications requiring maximum ripple current handling, the primary part is the appropriate selection.

Q: Which part should be selected for extended thermal lifetime?

A: The ELXZ250ELL222MK35S provides 7000 hours of operation at 105°C, compared to 5000 hours for the 228KXM025M. For applications requiring extended operational life at elevated temperatures, the substitute part offers superior performance.

Q: Are the electrical specifications identical?

A: Capacitance, voltage rating, tolerance, and operating temperature range are identical. ESR data for the substitute part is not specified in available documentation. Ripple current and impedance specifications differ between the two parts.

Q: What is the inventory status for both parts?

A: 228KXM025M: 865 pieces in stock. ELXZ250ELL222MK35S: 1794 pieces in stock.
