Engineering Selection Recommendations

Product Status Consideration: The SS17VA-R10025 is classified as obsolete. All listed substitute parts maintain active product status within the KEMET SS series, ensuring continued availability and manufacturing support.

Compliance and Certification: All substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory compliance profile of the original component. This ensures compatibility with current procurement and environmental standards.

Inductance Selection: Substitute selection depends on circuit inductance requirements. The original 2.5 mH specification can be replaced by:

Lower inductance options: SS11VL-11050 (5 mH) for applications requiring moderate filtering
Mid-range inductance: SS11VL-10062 (6.2 mH), SS21V-110067 (6.7 mH), SS11VL-R11076 (7.6 mH), SS20H-10080 (8 mH)
Higher inductance options: SS11V-R10093-CH (9.3 mH), SS11VL-R10093 (9.3 mH), SS20H-R10100 (10 mH)

Current Rating Compatibility: The original 1A rating is maintained across most substitutes. Enhanced current capability (1.1A) is available in SS11VL-11050, SS11VL-R11076, and SS21V-110067 for applications requiring higher current handling.

DC Resistance Considerations: DC resistance ranges from 380 mOhm (original) to 450 mOhm across substitutes. Selection should account for power dissipation requirements in the target application.

Physical Footprint: Substitute parts exhibit varied dimensions. SS11VL series components (22.00 x 14.50 mm) and SS20H series components (22.00 x 22.00 mm) represent larger footprints than the original SS17VA (17.00 x 12.00 mm). SS21V-110067 (20.50 x 16.50 mm) provides an intermediate size option. PCB layout constraints must be evaluated before selection.

Frequently Asked Questions (FAQ)

Q: Can I directly replace SS17VA-R10025 with any of the listed substitutes?

A: Direct replacement requires matching the circuit's inductance specification. The original 2.5 mH inductance value is not available in active substitute parts. Selection must be based on the application's actual inductance requirement within the 5 mH to 10 mH range covered by active alternatives.

Q: What is the difference between SS11VL and SS20H series substitutes?

A: SS11VL series components feature dimensions of 22.00 x 14.50 mm with heights ranging from 19.50 mm to 22.50 mm. SS20H series components have a larger footprint of 22.00 x 22.00 mm with heights of 18.50 mm. Selection depends on available PCB space and layout requirements.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original SS17VA-R10025 component.

Q: What is the difference between SS11VL-11050 and SS11VL-R10093?

A: SS11VL-11050 provides 5 mH inductance at 1.1A current rating with 400 mOhm DC resistance. SS11VL-R10093 provides 9.3 mH inductance at 1A current rating with 440 mOhm DC resistance. Selection depends on whether the application prioritizes higher current capability or higher inductance filtering.

Q: Can I use SS21V-110067 as a substitute?

A: SS21V-110067 is a valid substitute offering 6.7 mH inductance at 1.1A current rating. However, its physical dimensions (20.50 x 16.50 mm, height 24.50 mm) differ from the original component. PCB layout compatibility must be confirmed before selection.

Q: What is the operating temperature range for all substitutes?

A: All substitute parts operate across the same temperature range as the original component: -25°C to 120°C, ensuring thermal compatibility in target applications.

Q: How do I choose between substitutes with different current ratings?

A: If the application requires 1A or less, any substitute with 1A or higher rating is suitable. For applications requiring maximum current handling, SS11VL-11050, SS11VL-R11076, and SS21V-110067 offer 1.1A ratings. Verify the actual circuit current requirement before selection.
