SC-01-30G Common Mode Choke Equivalent & Substitute Parts

Part Overview

The SC-01-30G is a 3 mH common mode choke manufactured by KEMET, designed for power line filtering applications. This through-hole component operates at 1A maximum current with a DC resistance of 120 mOhm and supports dual-line filtering in the SC-G series. The part maintains Active product status with full RoHS3 compliance and operates across the industrial temperature range of -40°C to 105°C. Alternative models may be required due to inventory constraints, application-specific inductance requirements, or design optimization needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC-01-30G is determined by the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: KEMET
• Filter Type: Power Line
• Number of Lines: 2
• Mounting Type: Through Hole
• Voltage Rating - DC: 250V
• Voltage Rating - AC: 250V
• Operating Temperature Range: -40°C to 105°C
• Package / Case: Vertical, No Base, 4 PC Pin
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Inductance @ 100 kHz: Lower values acceptable for reduced filtering
• DC Resistance (Max): Variation within component tolerance
• Physical Dimensions: Variation acceptable within mounting constraints

The SC-01-10GS qualifies as a parametric equivalent within the SC-01 base product family. This substitute maintains all mandatory electrical and mechanical specifications while offering a lower inductance value of 1 mH at 100 kHz, suitable for applications requiring reduced filtering or higher frequency response.

Engineering Selection Recommendations

SC-01-30G Selection Criteria: Select the SC-01-30G when the application requires 3 mH inductance at 100 kHz for maximum common mode noise attenuation in power line filtering circuits. This part is suitable for low-frequency EMI suppression and maintains Active product status with full regulatory compliance.

SC-01-10GS Selection Criteria: Select the SC-01-10GS when the application permits lower inductance values (1 mH at 100 kHz) or when reduced component height is required within PCB layout constraints. The SC-01-10GS provides a smaller vertical profile (15.00 mm versus 17.50 mm) while maintaining identical electrical ratings and compliance certifications. The marginally higher DC resistance (130 mOhm versus 120 mOhm) remains within acceptable operating parameters for 1A current applications.

Both parts maintain identical voltage ratings, current capacity, operating temperature range, and regulatory compliance status. Selection between these parts depends solely on inductance requirement and physical space availability.

Frequently Asked Questions (FAQ)

Q: Can SC-01-10GS replace SC-01-30G in all applications?

A: No. The SC-01-10GS provides 1 mH inductance compared to the SC-01-30G's 3 mH. Substitution is valid only when the application circuit can function with reduced inductance and corresponding reduced low-frequency filtering capability. Verify circuit design specifications before substitution.

Q: What is the difference in physical dimensions between these parts?

A: The SC-01-30G measures 0.689" diameter × 0.551" width with 0.689" maximum height (17.50 mm × 14.00 mm × 17.50 mm). The SC-01-10GS measures 0.591" diameter × 0.335" width with 0.591" maximum height (15.00 mm × 8.50 mm × 15.00 mm). The SC-01-10GS occupies less vertical space, making it suitable for compact PCB layouts.

Q: Are both parts RoHS3 compliant?

A: Yes. Both SC-01-30G and SC-01-10GS carry ROHS3 Compliant status and are REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the DC resistance difference, and does it affect performance?

A: The SC-01-30G has 120 mOhm maximum DC resistance; the SC-01-10GS has 130 mOhm maximum. At the 1A maximum current rating, this 10 mOhm difference produces a maximum additional voltage drop of 10 mV across the SC-01-10GS. This variation is within acceptable tolerance for power line filtering applications.

Q: Are both parts rated for the same voltage and current?

A: Yes. Both parts are rated for 250V DC, 250V AC, and 1A maximum current. Electrical stress ratings are identical.

Q: Can these parts be used interchangeably in through-hole PCB designs?

A: Both parts use identical through-hole mounting (Vertical, No Base, 4 PC Pin package). PCB footprints are compatible. However, the SC-01-10GS's smaller height may require verification of clearance in confined spaces above the PCB.
