Substitute Part Grouping Explanation

Substitution eligibility for the SS24V-R15080-CH is determined by the following critical parameters:

Mandatory Matching Criteria:

• Manufacturer: KEMET
• Series: SS
• Filter Type: Power Line
• Number of Lines: 2
• Mounting Type: Through Hole
• Package / Case: Vertical, 4 PC Pin
• Voltage Rating - AC: 250V
• Operating Temperature Range: -25°C to 120°C
• RoHS Status: RoHS3 Compliant

Allowable Parameter Variation:

• Inductance @ 1 kHz: May vary based on application requirements
• Current Rating (Max): Must equal or exceed the application requirement
• DC Resistance (Max): Lower values are acceptable; higher values require circuit validation

The substitute part SS21V-R180044 maintains all mandatory matching criteria while presenting different inductance and current characteristics. This substitution is valid when the application circuit can accommodate the alternative electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the SS24V-R15080-CH and SS21V-R180044 are active production components with identical compliance certifications (RoHS3 Compliant, REACH Unaffected, ECCN EAR99). Selection between these parts depends on circuit-specific requirements:

Select SS24V-R15080-CH when:

• Application requires 8 mH inductance at 1 kHz
• Circuit design specifies 1.5A maximum current
• PCB layout accommodates the larger footprint (26.00mm x 19.00mm x 31.50mm height)

Select SS21V-R180044 when:

• Application requires 4.4 mH inductance at 1 kHz
• Circuit design permits 1.8A maximum current
• Space constraints favor the smaller footprint (20.50mm x 16.50mm x 24.50mm height)
• Lower DC resistance (200 mOhm vs 240 mOhm) provides circuit advantage

Both parts operate across the identical temperature range (-25°C to 120°C) and voltage rating (250V AC), ensuring thermal and electrical compatibility within their respective parameter sets.

Frequently Asked Questions (FAQ)

Q: Can SS21V-R180044 be used as a direct replacement for SS24V-R15080-CH?

A: Direct replacement is possible only if the application circuit can function with 4.4 mH inductance instead of 8 mH. The substitute part has higher current rating (1.8A vs 1.5A) and lower DC resistance (200 mOhm vs 240 mOhm), which are advantageous characteristics. However, the reduced inductance value must be validated against the filtering requirements of the specific power line application.

Q: Are there physical compatibility concerns when substituting these parts?

A: Yes. The SS21V-R180044 has a smaller footprint (20.50mm x 16.50mm vs 26.00mm x 19.00mm) and lower height (24.50mm vs 31.50mm). PCB layouts designed for the SS24V-R15080-CH may require modification to accommodate the SS21V-R180044. Verify mounting hole spacing and clearance requirements before substitution.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both SS24V-R15080-CH and SS21V-R180044 are RoHS3 Compliant, REACH Unaffected, and classified as EAR99. They meet identical environmental and export compliance standards.

Q: What is the significance of the different DC resistance values?

A: The SS21V-R180044 has 200 mOhm maximum DC resistance compared to 240 mOhm for the SS24V-R15080-CH. Lower DC resistance reduces power dissipation in the component. This difference is relevant in applications where thermal management or efficiency is a design consideration.

Q: Can the SS24V-R15080-CH be substituted with SS21V-R180044 in all power line filtering applications?

A: No. Substitution is valid only when the application circuit specifications permit the lower inductance value (4.4 mH vs 8 mH). Power line filtering effectiveness depends on inductance matching the target frequency range. Verify that the substitute part's inductance value meets the EMI/RFI filtering requirements of the specific application before implementation.
