Substitute Part Grouping Explanation

Substitute parts for the 226SMH035M are categorized into three groups based on electrical and mechanical compatibility:

Direct Equivalents (Same Voltage Rating - 35V): Parts maintaining identical 35 V voltage rating, 22 µF capacitance, ±20% tolerance, and compatible SMD radial can package dimensions. These parts satisfy direct pin-for-pin and footprint compatibility requirements.

Upgrade Equivalents (Higher Voltage Rating - 50V): Parts with elevated 50 V voltage rating while maintaining 22 µF capacitance and ±20% tolerance. These provide enhanced voltage margin and are mechanically compatible with the same PCB footprint. Voltage upgrades do not require circuit redesign when the original 35 V specification permits higher-rated components.

Parametric Equivalents (35V, Alternate Manufacturers): Parts from different manufacturers with matching 35 V rating and 22 µF capacitance but potentially different ESR, ripple current, or lifetime characteristics. These maintain electrical compatibility while offering alternative sourcing options.

Key Substitution Criteria:

Capacitance: 22 µF (fixed requirement)
Voltage Rating: 35 V minimum (50 V upgrades acceptable)
Tolerance: ±20% (fixed requirement)
Package: Radial, Can - SMD with 6.30mm diameter and 5.50mm height maximum
Mounting: Surface Mount compatible with 6.60mm x 6.60mm land pattern
Polarization: Polar (fixed requirement)

Engineering Selection Recommendations

Direct Equivalent Selection (35V Rating):

For applications requiring direct replacement without circuit modification, select from active-status parts with 35 V rating: 865060543003 (Würth Elektronik), UWT1V220MCL1GB (Nichicon), or RSVVS220M1GDC3001U (Elna America). The Würth Elektronik 865060543003 offers extended 2000-hour lifetime at 105°C compared to the original 1000-hour specification, with significantly higher ripple current capability (149.5 mA @ 120 Hz versus 60 mA). The Nichicon UWT1V220MCL1GB maintains 1000-hour lifetime matching the original part but provides lower ripple current performance.

Voltage Upgrade Selection (50V Rating):

For enhanced circuit reliability with voltage margin, select 50 V rated parts: 865060643006, 865080643008 (Würth Elektronik), EEV226M050S9GAA (KEMET), or UUD1H220MCL1GS (Nichicon). All upgrade parts provide 2000-hour lifetime at 105°C. The Würth Elektronik 865060643006 and 865080643008 deliver superior ripple current performance. The KEMET EEV226M050S9GAA carries AEC-Q200 automotive qualification and is suitable for automotive-grade applications. The Nichicon UUD1H220MCL1GS also carries AEC-Q200 rating with 2000-hour lifetime but exhibits maximum height of 6.10mm, requiring PCB clearance verification.

Avoid Selection:

Parts with Obsolete or Last Time Buy status (35SKV22M6.3X5.5, 35SZV22M6.3X5.5) should not be selected for new designs due to manufacturing discontinuation and limited inventory availability.

Compliance Verification:

All recommended active-status parts maintain ROHS3 compliance, MSL Level 1 (unlimited moisture sensitivity), and EAR99 export classification matching the original 226SMH035M specification.

Frequently Asked Questions (FAQ)

Q: Can I use a 50V rated capacitor in place of the 35V 226SMH035M?

A: Yes. A 50 V rated capacitor with identical 22 µF capacitance and ±20% tolerance is electrically compatible. The higher voltage rating provides additional safety margin and does not affect circuit operation when the original design operates below 35 V. Physical dimensions must remain compatible with the PCB footprint (6.60mm x 6.60mm land pattern, maximum height 5.50mm for standard compatibility).

Q: What is the difference between direct equivalents and upgrade equivalents?

A: Direct equivalents maintain the original 35 V voltage rating and are suitable for one-to-one replacement. Upgrade equivalents feature 50 V rating, providing enhanced voltage margin and typically extended lifetime (2000 hours versus 1000 hours at 105°C). Upgrade parts are mechanically compatible with the same PCB footprint but offer improved performance characteristics.

Q: Does ESR (Equivalent Series Resistance) affect substitution compatibility?

A: ESR affects ripple current handling and thermal performance but does not prevent substitution. The 226SMH035M specifies 10.55 Ohm ESR @ 120Hz. Substitute parts with lower ESR values (such as Würth Elektronik 865060543003 with 440 mOhms impedance) provide superior high-frequency performance and reduced heat generation. Higher ESR values may be acceptable if ripple current requirements are not exceeded.

Q: Are Rubycon 35SKV22M6.3X5.5 and 35SZV22M6.3X5.5 suitable replacements?

A: These Rubycon parts are parametrically equivalent but carry Obsolete and Last Time Buy status respectively. They should not be selected for new designs or long-term production due to manufacturing discontinuation and limited inventory. Active-status alternatives from Würth Elektronik, Nichicon, Elna America, and KEMET are recommended.

Q: What is the significance of AEC-Q200 rating on substitute parts?

A: AEC-Q200 is an automotive-grade qualification standard. Parts carrying this rating (EEV226M050S9GAA from KEMET and UUD1H220MCL1GS from Nichicon) are suitable for automotive applications requiring enhanced reliability and qualification testing. General-purpose applications do not require AEC-Q200 certification.

Q: Can I substitute a part with different height if the land pattern matches?

A: Height differences must be evaluated against PCB clearance requirements. The original 226SMH035M specifies 5.50mm maximum seated height. Substitute parts with heights up to 5.65mm (EEV226M050S9GAA) or 6.10mm (UUD1H220MCL1GS) require verification that component clearance does not conflict with adjacent PCB features, solder mask openings, or assembly equipment constraints.

Q: What packaging format should I specify when ordering substitute parts?

A: The original 226SMH035M is supplied in Tape & Reel (TR) packaging. Most substitute parts maintain TR packaging for automated assembly compatibility. Verify packaging format during procurement to ensure compatibility with pick-and-place equipment and reel specifications.

Q: How do ripple current ratings affect part selection?

A: Ripple current capacity determines the maximum AC current the capacitor can handle without exceeding temperature limits. The 226SMH035M specifies 60 mA @ 120 Hz and 90 mA @ 100 kHz. Substitute parts with higher ripple current ratings (such as Würth Elektronik 865060543003 with 149.5 mA @ 120 Hz) provide additional margin for high-frequency switching applications. Parts with lower ripple current ratings must not be used in applications exceeding their specified limits.
