The substitute part UWJ0J220MCL1GB manufactured by Nichicon satisfies all critical matching parameters and important compatibility requirements, establishing it as a parametric equivalent for the 226SML6R3M.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (226SML6R3M - Cornell Dubilier): The 226SML6R3M maintains Active product status with current inventory availability of 785 pieces. This part is recommended for new designs and applications where supply continuity is a priority. The part carries ROHS3 compliance and REACH Unaffected status, supporting unrestricted use in regulated markets.

Substitute Part (UWJ0J220MCL1GB - Nichicon): The UWJ0J220MCL1GB is classified as Obsolete product status. This part satisfies all electrical and mechanical substitution criteria and maintains ROHS3 compliance. However, the Obsolete designation indicates limited future availability. This part is suitable for replacement applications, legacy system repairs, or situations where existing inventory must be utilized. The REACH Affected status requires verification of compliance requirements for specific end-use applications.

Selection Basis:

• Both parts meet identical electrical specifications (capacitance, voltage, tolerance, operating temperature, lifetime)
• Both parts share identical physical dimensions and land sizes for direct PCB compatibility
• Both parts maintain equivalent MSL ratings and RoHS compliance
• Selection between primary and substitute should be based on supply availability, product lifecycle status, and regulatory requirements for the specific application

Frequently Asked Questions (FAQ)

Q: Can UWJ0J220MCL1GB be used as a direct replacement for 226SML6R3M on existing PCBs?

A: Yes. Both parts share identical physical dimensions (0.157" Dia × 0.217" H), land sizes (0.169" L × 0.169" W), and mounting type (Surface Mount). The parts are mechanically and electrically interchangeable at the PCB level without requiring layout modifications.

Q: What is the significance of the Obsolete status for UWJ0J220MCL1GB?

A: Obsolete status indicates that Nichicon has discontinued active production and distribution of this part. While existing inventory may be available through authorized distributors, future procurement cannot be guaranteed. This designation does not affect the part's technical performance or compliance status.

Q: Are there differences in ESR (Equivalent Series Resistance) between these parts?

A: The 226SML6R3M specifies ESR of 21.1 Ohm @ 120 Hz. The UWJ0J220MCL1GB does not provide ESR specification in the available data. Both parts provide ripple current ratings at 120 Hz (31 mA and 28 mA respectively), indicating comparable performance characteristics for general-purpose applications.

Q: What does REACH Affected status mean for the substitute part?

A: REACH Affected status indicates that the UWJ0J220MCL1GB may contain substances subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. The primary part (226SML6R3M) is listed as REACH Unaffected. Applications subject to REACH compliance requirements should verify the specific substance declarations provided by Nichicon before selecting this substitute.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts specify identical operating temperature ranges of -40°C to 85°C and identical lifetime ratings of 2000 Hrs @ 85°C. They are suitable for equivalent thermal environments and reliability profiles.

Q: What is the difference in ripple current ratings?

A: The 226SML6R3M specifies 31 mA @ 120 Hz ripple current. The UWJ0J220MCL1GB specifies 28 mA @ 120 Hz. Both ratings are within comparable ranges for general-purpose applications. The substitute part also provides high-frequency ripple current rating of 42 mA @ 10 kHz, which is not specified for the primary part.
