Equivalent & Substitute Parts for 228SAK016M

Part Overview

The 228SAK016M is a 2200 µF, 16 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the SAK series. This radial, through-hole component is designed for general-purpose applications requiring stable capacitance and extended operational life. The part is Active in product status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when inventory constraints require component alternatives that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the 228SAK016M are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalent (Direct Substitution): The URS1C222MHD from Nichicon maintains identical electrical specifications: 2200 µF capacitance, 16 V rated voltage, ±20% tolerance, 2000 Hrs @ 85°C lifetime, and matching mechanical dimensions (7.50 mm lead spacing, 16.00 mm diameter, 16.50 mm height). This part qualifies as a direct substitute with no circuit redesign required.

Similar Manufacturer Part (Voltage-Rated Alternative): The SK222M035ST from Cornell Dubilier Electronics shares the same manufacturer family, capacitance value (2200 µF), tolerance (±20%), and lifetime rating (2000 Hrs @ 85°C). However, this part carries a higher voltage rating of 35 V and increased physical height (34.00 mm). This part is suitable for applications where higher voltage margin is acceptable and board space permits the increased height.

Substitution logic is based strictly on: capacitance value, tolerance, voltage rating compatibility, lifetime at temperature, lead spacing, and through-hole mounting configuration.

Engineering Selection Recommendations

For Direct Substitution (No Circuit Modification Required): The URS1C222MHD from Nichicon is the preferred parametric equivalent. It maintains identical voltage rating (16 V), capacitance (2200 µF), tolerance (±20%), and physical dimensions. Both parts are Active in product status with ROHS3 compliance and REACH Unaffected certification. Ripple current specifications are equivalent within measurement tolerance (1.16 A vs. 1.17 A @ 120 Hz; 1.334 A vs. 1.3455 A @ 10 kHz). This part is suitable for direct PCB substitution without design changes.

For Higher Voltage Margin Applications: The SK222M035ST from Cornell Dubilier Electronics provides a 35 V rated voltage with the same 2200 µF capacitance and ±20% tolerance. This part is appropriate when circuit design permits increased board height (34.00 mm vs. 16.50 mm) and when higher voltage headroom is required. Both parts share identical compliance certifications (ROHS3, REACH Unaffected) and Active product status.

All three parts are through-hole radial can packages with 7.50 mm lead spacing, suitable for standard PCB footprints designed for this configuration.

Frequently Asked Questions (FAQ)

Q: Can the URS1C222MHD replace the 228SAK016M without PCB modification? A: Yes. The URS1C222MHD is a parametric equivalent with identical voltage rating (16 V), capacitance (2200 µF), tolerance (±20%), and physical dimensions (7.50 mm lead spacing, 16.00 mm diameter, 16.50 mm height). Direct substitution on the PCB is possible.

Q: What is the key difference between the 228SAK016M and SK222M035ST? A: The SK222M035ST has a higher voltage rating (35 V vs. 16 V) and greater physical height (34.00 mm vs. 16.50 mm). Both share identical capacitance (2200 µF), tolerance (±20%), and lifetime rating (2000 Hrs @ 85°C). The SK222M035ST is suitable only if board space permits the increased height.

Q: Are all three parts RoHS compliant? A: Yes. The 228SAK016M, URS1C222MHD, and SK222M035ST are all ROHS3 compliant and REACH Unaffected.

Q: What is the operating temperature range for these capacitors? A: All three parts operate across -40°C to 85°C with a rated lifetime of 2000 hours at 85°C.

Q: Do the ripple current ratings differ significantly between the main part and substitutes? A: The 228SAK016M and URS1C222MHD have equivalent ripple current ratings (1.17 A vs. 1.16 A @ 120 Hz; 1.3455 A vs. 1.334 A @ 10 kHz). The SK222M035ST ripple current is not specified in the provided data.

Q: Can I use the SK222M035ST in a circuit designed for 16 V operation? A: Yes. The SK222M035ST is rated for 35 V, which exceeds the 16 V requirement. However, verify that board space accommodates the increased height (34.00 mm).

Q: What is the lead spacing for all three parts? A: All three parts have 7.50 mm lead spacing, compatible with standard through-hole PCB footprints for 2200 µF radial capacitors.
