Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SSR21NH-20064 are qualified based on the following criteria:

Core Compatibility Parameters:

• Product category: 2-line common mode choke, through-hole mounted
• Mounting type: Through hole with vertical, 4 PC pin configuration
• Voltage rating: 250V AC minimum
• Operating temperature range: -25°C to 120°C
• Compliance: RoHS3 compliant, REACH unaffected
• Manufacturer: KEMET

Allowable Variations:

• Inductance at 10 kHz: May vary from the primary specification
• Current rating: May exceed or be lower than 2A
• DC resistance: May vary within acceptable limits
• Physical dimensions: May differ while maintaining through-hole compatibility
• Series designation: May differ within KEMET's common mode choke portfolio

Substitutes are identified when these core parameters align, enabling functional replacement in applications where the specific inductance and current characteristics of the SSR21NH-20064 are not absolute requirements.

Engineering Selection Recommendations

SSR10HS-22026 Substitution: The SSR10HS-22026 is an active KEMET product with RoHS3 compliance and identical core specifications to the SSR21NH-20064 regarding mounting type, package configuration, voltage rating, and operating temperature range. This part features lower inductance (2.6 mH versus 6.4 mH) and slightly higher current capacity (2.2A versus 2A). DC resistance is marginally higher at 100 mOhm. Selection of this substitute is appropriate when circuit design permits reduced inductance values or when higher current handling is required.

SSRH7HS-M20013 Substitution: The SSRH7HS-M20013 is an active KEMET product with RoHS3 compliance and identical core specifications regarding mounting type, package configuration, voltage rating, and operating temperature range. This part features significantly lower inductance (1.3 mH versus 6.4 mH) and lower DC resistance (80 mOhm versus 90 mOhm). Physical dimensions are reduced compared to the main part. Selection of this substitute is appropriate when circuit design permits substantially reduced inductance values or when compact form factor is advantageous.

Both substitutes maintain full compliance with RoHS3 and REACH requirements and are classified as Active products, ensuring continued availability and support.

Frequently Asked Questions (FAQ)

Q: What determines whether SSR10HS-22026 or SSRH7HS-M20013 can replace SSR21NH-20064?

A: Substitution is determined by circuit-level requirements for inductance value, current capacity, and physical space constraints. Both substitutes maintain identical mounting type (through-hole), package configuration (vertical, 4 PC pin), voltage rating (250V AC), and operating temperature range (-25°C to 120°C). The primary differences are inductance (6.4 mH, 2.6 mH, and 1.3 mH respectively) and current ratings (2A, 2.2A, and 2A). Selection depends on whether the application can function with lower inductance values.

Q: Are all three parts physically interchangeable?

A: All three parts share identical mounting type (through-hole) and package configuration (vertical, 4 PC pin), enabling direct pin-compatible installation. However, physical dimensions vary: SSR21NH-20064 measures 0.906" L x 0.906" W x 0.571" H; SSR10HS-22026 measures 0.531" H; SSRH7HS-M20013 measures 0.709" L x 0.571" W x 0.472" H. PCB layout and clearance requirements must be verified before substitution.

Q: Do all substitutes meet the same compliance standards?

A: Yes. SSR21NH-20064, SSR10HS-22026, and SSRH7HS-M20013 are all RoHS3 compliant, REACH unaffected, and classified as Active products by KEMET. All three parts carry ECCN EAR99 classification and HTSUS code 8548.00.0000.

Q: What is the impact of DC resistance differences?

A: DC resistance values are 90 mOhm (SSR21NH-20064), 100 mOhm (SSR10HS-22026), and 80 mOhm (SSRH7HS-M20013). These variations affect power dissipation and thermal performance. Applications with strict power budget constraints must account for these differences in circuit analysis.

Q: Can SSR10HS-22026 be used in applications requiring 6.4 mH inductance?

A: No. SSR10HS-22026 provides 2.6 mH inductance, which is insufficient for applications with specific inductance requirements of 6.4 mH. Substitution is only valid when circuit design permits operation with reduced inductance values.

Q: What is the inventory status of these parts?

A: SSR21NH-20064 has 845 pieces in stock; SSR10HS-22026 has 811 pieces in stock; SSRH7HS-M20013 has 1527 pieces in stock. All are listed as new original inventory.
