Engineering Selection Recommendations

ATB226M035 (Upgrade Substitute)

The ATB226M035 is classified as an upgrade substitute for the 226SML025MD5. This component maintains identical capacitance and tolerance specifications while providing enhanced electrical performance through reduced ESR (8.44 Ohm versus 12.06 Ohm @ 120Hz) and significantly increased ripple current handling (112 mA @ 120 Hz versus 38 mA). The rated voltage is increased to 35 V, providing additional design margin for circuits operating at or near 25 V nominal levels. Extended thermal performance is offered through 3000 hours lifetime at 105°C compared to 2000 hours at 85°C for the original part. Operating temperature range extends to -55°C to 105°C. The ATB226M035 maintains ROHS3 compliance and MSL rating 1 status. Physical dimensions are compatible with the original part, though seated height increases marginally to 0.224" (5.70mm) and surface mount land size width increases to 0.228" W (5.80mm). Both components are manufactured by Cornell Dubilier / Illinois Capacitor and carry Active product status with bulk packaging availability.

UWR1E220MCL1GB (Parametric Equivalent)

The UWR1E220MCL1GB is classified as a parametric equivalent substitute for the 226SML025MD5. This component is manufactured by Nichicon and maintains identical capacitance, tolerance, voltage rating, and operating temperature range specifications. Ripple current performance is comparable at 42 mA @ 120 Hz and 63 mA @ 10 kHz. Physical dimensions and surface mount land size are identical to the original part. Both components maintain ROHS3 compliance and MSL rating 1 status. The UWR1E220MCL1GB is supplied in Tape & Reel (TR) packaging format, contrasting with the Bulk packaging of the original part. This component carries Obsolete product status, indicating discontinued manufacturing and limited inventory availability. ESR specification is not provided for this part. The lifetime specification matches the original part at 2000 hours @ 85°C.

Frequently Asked Questions (FAQ)

Q: Can the ATB226M035 be used as a direct replacement for the 226SML025MD5 in all applications?

A: The ATB226M035 satisfies all primary substitution criteria and maintains physical compatibility with the original part. The increased voltage rating (35 V versus 25 V) and improved electrical performance characteristics (lower ESR, higher ripple current) make this component suitable for applications where the original part is specified. The marginal increase in seated height (0.224" versus 0.217") and surface mount land size width (0.228" versus 0.209") must be verified against specific PCB layout constraints. Both components are manufactured by the same supplier and carry Active product status.

Q: What is the difference between the ATB226M035 and UWR1E220MCL1GB substitutes?

A: The ATB226M035 is classified as an upgrade substitute offering enhanced performance through reduced ESR, increased ripple current capability, and extended thermal lifetime. The UWR1E220MCL1GB is classified as a parametric equivalent, maintaining electrical specifications identical to the original part while being manufactured by a different supplier (Nichicon versus Cornell Dubilier / Illinois Capacitor). The ATB226M035 carries Active product status with bulk packaging, while the UWR1E220MCL1GB carries Obsolete product status with Tape & Reel packaging.

Q: Are there physical compatibility concerns when substituting the ATB226M035?

A: The ATB226M035 maintains identical diameter (0.197" / 5.00mm) and comparable height (0.224" / 5.70mm versus 0.217" / 5.50mm) to the original part. The surface mount land size width increases from 0.209" to 0.228" W (5.30mm to 5.80mm). PCB layout verification is required to confirm that the increased land size width does not conflict with existing trace routing or component placement constraints.

Q: Why is the UWR1E220MCL1GB marked as Obsolete?

A: The UWR1E220MCL1GB carries Obsolete product status, indicating that Nichicon has discontinued manufacturing this component. Obsolete status typically reflects end-of-life decisions by the manufacturer and may result in limited inventory availability through distribution channels. Active product alternatives such as the ATB226M035 or continued availability of the 226SML025MD5 are recommended for new designs or long-term production requirements.

Q: What packaging format differences exist between these components?

A: The 226SML025MD5 and ATB226M035 are supplied in Bulk packaging format, suitable for applications requiring individual component handling or custom packaging solutions. The UWR1E220MCL1GB is supplied in Tape & Reel (TR) format, optimized for automated assembly processes and high-volume production environments. Packaging format selection depends on manufacturing process requirements and inventory management practices.

Q: Are all substitute parts RoHS and REACH compliant?

A: All three components (226SML025MD5, ATB226M035, and UWR1E220MCL1GB) maintain ROHS3 compliance and REACH Unaffected status, confirming compliance with environmental and hazardous substance regulations applicable to electronic components.

Q: How do the ripple current specifications compare across these components?

A: The 226SML025MD5 handles 38 mA @ 120 Hz and 57 mA @ 100 kHz. The ATB226M035 provides significantly higher ripple current capability at 112 mA @ 120 Hz and 160 mA @ 100 kHz, representing a 195% increase at low frequency. The UWR1E220MCL1GB offers comparable performance to the original part at 42 mA @ 120 Hz and 63 mA @ 10 kHz. Applications requiring high ripple current handling benefit from the ATB226M035 upgrade.

Q: What is the significance of ESR differences between these components?

A: ESR (Equivalent Series Resistance) directly affects component heating and voltage ripple performance. The 226SML025MD5 exhibits 12.06 Ohm ESR @ 120Hz, while the ATB226M035 provides reduced ESR at 8.44 Ohm @ 120Hz, representing a 30% improvement. Lower ESR reduces power dissipation and improves frequency response characteristics. The UWR1E220MCL1GB does not specify ESR, limiting comparative analysis for this parameter.
