Equivalent & Substitute Parts for 228KBM035M

Part Overview

The Cornell Dubilier 228KBM035M is a 2200 µF, 35 V aluminum electrolytic capacitor in radial, can package configuration. This component is classified as Active and is suitable for general-purpose applications requiring stable capacitance and extended operational life at elevated temperatures. The part is rated for 10,000 hours at 105°C with a ±20% capacitance tolerance.

Engineering Selection Recommendations

Active Status Parts (Recommended for New Designs):

The following substitute parts carry Active product status and are suitable for new design implementations:

35YXJ2200M16X25 (Rubycon YXJ Series): Active status with lower impedance (21 mOhms) and reduced physical height (27.00mm). Suitable for space-constrained applications.
35ZLH2200MEFC16X25 (Rubycon ZLH Series): Active status with optimized impedance (13 mOhms) and reduced physical height (27.00mm). Offers improved high-frequency ripple current performance.
EEU-FR1V222 (Panasonic FR-A Series): Active status with low impedance (14 mOhms) and reduced physical height (27.00mm). Provides highest ripple current capability at both low and high frequencies.
EKZM350ELL222ML25S (Chemi-Con KZM Series): Active status with optimized impedance (13 mOhms) and minimal physical height (26.50mm). Suitable for compact PCB layouts.

Legacy Status Parts (Existing Design Support Only):

The following substitute parts carry "Not For New Designs" product status and are restricted to replacement applications in existing designs:

UHE1V222MHD (Nichicon UHE Series): Not For New Designs status. REACH Affected designation. Suitable only for direct replacement in legacy systems.
UHW1V222MHD6 (Nichicon UHW Series): Not For New Designs status. Suitable only for direct replacement in legacy systems.

Compliance Considerations:

All substitute parts are ROHS3 Compliant and carry EAR99 ECCN classification. The UHE1V222MHD carries REACH Affected status, requiring additional regulatory review for new applications. All other substitutes are REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 228KBM035M with any of the listed parts?

A: Substitution is possible only with parts that maintain identical electrical specifications (2200 µF, 35 V, ±20% tolerance, 10,000 Hrs @ 105°C) and mechanical compatibility (0.630" diameter, 0.295" lead spacing, through-hole radial can package). All listed parts meet these requirements. However, physical height differences may require PCB layout verification.

Q: What is the difference between Active and "Not For New Designs" status?

A: Active status parts are approved for incorporation into new product designs and are expected to remain in production. "Not For New Designs" parts are available for replacement in existing systems but should not be selected for new development. The Nichicon UHE1V222MHD and UHW1V222MHD6 carry this legacy designation.

Q: Does the physical height difference affect PCB compatibility?

A: The 228KBM035M has a maximum seated height of 1.260" (32.00mm). Most substitute parts are shorter (27.00mm to 26.50mm), which provides additional clearance. The UHE1V222MHD at 1.240" (31.50mm) is nearly equivalent. Shorter parts do not create compatibility issues; however, PCB layout should be verified to confirm adequate component clearance in the application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 Compliant. However, the Nichicon UHE1V222MHD carries REACH Affected status, which may require additional regulatory documentation for certain applications or markets.

Q: What is the significance of impedance differences among substitute parts?

A: Impedance values range from 13 mOhms to 25 mOhms across the part list. Lower impedance values (13-14 mOhms) indicate improved high-frequency performance and lower voltage ripple. The 228KBM035M at 25 mOhms represents a higher impedance design. Substitutes with lower impedance provide enhanced performance in ripple-sensitive applications.

Q: Can I use a substitute part with different ripple current ratings?

A: Ripple current ratings vary among substitutes based on manufacturer design. All listed parts meet the 10,000-hour lifetime specification at 105°C. Selection should be based on the specific ripple current requirements of the application circuit. Higher ripple current capability provides additional design margin.

Q: What should I consider when selecting between multiple active substitutes?

A: Selection criteria include: (1) physical height constraints in the PCB layout, (2) impedance requirements for ripple performance, (3) ripple current specifications for the application, (4) manufacturer availability and lead time, and (5) cost considerations. All active substitutes are electrically equivalent for the specified 2200 µF, 35 V, ±20% tolerance application.

Q: Is the lead spacing identical across all parts?

A: Yes, all parts maintain 0.295" (7.50mm) lead spacing, ensuring direct PCB footprint compatibility. The diameter is also standardized at 0.630" (16.00mm) across all parts.
