SC-01-20G Common Mode Choke Equivalent & Substitute Parts

Part Overview

The SC-01-20G is a 2 mH common mode choke manufactured by KEMET, designed for power line filtering applications in two-line configurations. This through-hole component operates at 1A maximum current with 100 mOhm DC resistance and is rated for 250V DC/AC operation across an extended temperature range of -40°C to 105°C. The part maintains Active product status and is ROHS3 compliant. Substitute parts are identified when inventory constraints, lead time requirements, or application-specific parameter adjustments necessitate alternative component selection within the SC-G series.

The SC-01-20G can be substituted with SC-01-30G when application requirements permit higher inductance values and corresponding increases in DC resistance within the same electrical and mechanical envelope.

Parameter Comparison

Engineering Selection Recommendations

Both SC-01-20G and SC-01-30G maintain Active product status with full ROHS3 compliance and REACH unaffected designation. Selection between these parts is determined by circuit inductance requirements:

SC-01-20G Selection Criteria:

• Applications requiring 2 mH inductance at 100 kHz
• Systems where lower DC resistance (100 mOhm) is critical for power dissipation budgets
• Designs with inductance-sensitive filtering specifications

SC-01-30G Selection Criteria:

• Applications requiring 3 mH inductance at 100 kHz
• Systems where increased filtering attenuation justifies the 20 mOhm increase in DC resistance
• Designs with inductance-sensitive filtering specifications that benefit from higher impedance

Both parts share identical mechanical footprints, electrical ratings, temperature ranges, and compliance certifications, enabling direct substitution when inductance and DCR parameters align with circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can SC-01-30G replace SC-01-20G in any application?

A: SC-01-30G can replace SC-01-20G only when the application circuit design permits 3 mH inductance and 120 mOhm DC resistance. The higher inductance value will increase filtering attenuation, and the additional 20 mOhm resistance will increase power dissipation. Circuit validation is required to confirm compatibility.

Q: Are the physical dimensions identical between SC-01-20G and SC-01-30G?

A: Yes. Both parts share identical dimensions of 0.689" Dia x 0.551" W (17.50mm x 14.00mm) with maximum height of 0.689" (17.50mm). Both use Vertical, No Base, 4 PC Pin packaging, enabling direct PCB footprint compatibility.

Q: What is the primary difference between SC-01-20G and SC-01-30G?

A: The primary differences are inductance value (2 mH versus 3 mH at 100 kHz) and maximum DC resistance (100 mOhm versus 120 mOhm). All other electrical ratings, temperature ranges, voltage specifications, and compliance certifications are identical.

Q: Are both parts ROHS3 compliant?

A: Yes. Both SC-01-20G and SC-01-30G are ROHS3 compliant with REACH unaffected status, meeting current environmental and regulatory requirements.

Q: What is the current rating for both parts?

A: Both SC-01-20G and SC-01-30G are rated for maximum continuous current of 1A, with identical voltage ratings of 250V DC and 250V AC.

Q: Can these parts be used in applications outside the -40°C to 105°C temperature range?

A: No. Both parts are specified for operation within -40°C to 105°C. Applications requiring operation outside this range require alternative component selection.
