Key Parameters

Substitute Part Grouping Explanation

The SC-10-100 is identified as a parametric equivalent within the SC series common mode choke family. Substitution eligibility is determined by the following criteria:

Matching Parameters (Required for Substitution):

• Manufacturer: KEMET (same manufacturer)
• Series: SC (same product family)
• Filter Type: Power Line (same application category)
• Number of Lines: 2 (same configuration)
• Current Rating (Max): 10A (identical current capacity)
• Voltage Rating - DC: 250V (identical voltage specification)
• Voltage Rating - AC: 250V (identical voltage specification)
• Operating Temperature: -40°C ~ 105°C (identical temperature range)
• Mounting Type: Through Hole (same mounting method)
• Package / Case: Horizontal, No Base, 4 PC Pin (same package configuration)
• Product Status: Active (current production status)
• RoHS Status: ROHS3 Compliant (equivalent compliance)

Differing Parameters (Application-Dependent):

• Inductance @ Frequency: 5 mH @ 100 kHz (main part) vs. 1 mH @ 100 kHz (substitute)
• DC Resistance (Max): 25 mOhm (main part) vs. 20 mOhm (substitute)
• Size / Dimension: 1.929" Dia / 49.00mm (main part) vs. 1.339" Dia / 34.00mm (substitute)
• Height (Max): 1.063" / 27.00mm (main part) vs. 0.945" / 24.00mm (substitute)

The SC-10-100 operates at a lower inductance value (1 mH vs. 5 mH) with reduced DC resistance and smaller physical dimensions. Selection between these parts depends on the specific inductance requirement of the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both SC-10-500 and SC-10-100 maintain Active product status with full RoHS3 compliance and REACH unaffected designation, ensuring regulatory alignment for current production applications. The primary selection criterion is inductance value: the SC-10-500 provides 5 mH filtering performance, while the SC-10-100 delivers 1 mH performance. Circuit design specifications determine which inductance value is required. The SC-10-100 offers the secondary benefit of reduced physical footprint (34.00mm diameter vs. 49.00mm) and lower DC resistance (20 mOhm vs. 25 mOhm), which may provide advantages in space-constrained layouts or applications sensitive to resistive losses. Both parts support identical current ratings (10A), voltage specifications (250V DC/AC), and operating temperature ranges (-40°C ~ 105°C), confirming mechanical and thermal compatibility within the SC series platform.

Frequently Asked Questions (FAQ)

Q: Can SC-10-100 directly replace SC-10-500 in my circuit?

A: Direct replacement depends on your circuit's inductance requirement. The SC-10-100 operates at 1 mH while the SC-10-500 operates at 5 mH. If your design specifies 5 mH inductance, the SC-10-100 will not provide equivalent filtering performance. If your design can operate with 1 mH inductance, the SC-10-100 is mechanically and electrically compatible.

Q: Are there physical space differences between these parts?

A: Yes. The SC-10-500 measures 1.929" diameter (49.00mm) with 1.063" height (27.00mm). The SC-10-100 measures 1.339" diameter (34.00mm) with 0.945" height (24.00mm). The SC-10-100 is smaller and may fit in space-constrained PCB layouts where the SC-10-500 cannot be accommodated.

Q: Do both parts have the same current rating?

A: Yes. Both SC-10-500 and SC-10-100 are rated for 10A maximum current, supporting identical power line filtering applications at this current level.

Q: What is the difference in DC resistance between these parts?

A: The SC-10-500 has a maximum DC resistance of 25 mOhm, while the SC-10-100 has a maximum DC resistance of 20 mOhm. The SC-10-100 exhibits lower resistive losses, which may be beneficial in applications where power dissipation is a design consideration.

Q: Are both parts RoHS compliant?

A: Yes. Both SC-10-500 and SC-10-100 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: Can I use these parts interchangeably in production?

A: Interchangeability is limited to applications where the inductance difference (5 mH vs. 1 mH) does not affect circuit performance. Both parts share identical mounting type (Through Hole), package configuration (Horizontal, No Base, 4 PC Pin), current rating (10A), and voltage specifications (250V DC/AC), but the inductance value must match your circuit design requirements.
