SC-05-200 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The SC-05-200 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 a rated current of 5A with a maximum DC resistance of 70 mOhm and is rated for 250V DC/AC operation across an operating temperature range of -40°C to 105°C. The part maintains Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are required for circuit design flexibility, inventory management, or component availability considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SC-05-200 are identified based on the following criteria:

Electrical Compatibility Parameters:

• Filter Type: Power Line (same category)
• Number of Lines: 2 (same configuration)
• Voltage Rating: 250V DC/AC (same or higher rating)
• Operating Temperature Range: -40°C to 105°C (same or compatible range)
• Mounting Type: Through Hole (same physical mounting)
• Package Configuration: Vertical, No Base, 4 PC Pin (same footprint)

Allowable Parameter Variations:

• Inductance value may differ based on frequency specification
• Current Rating may be equal or higher than the original part
• DC Resistance may be equal or lower than the original part
• Physical dimensions may vary within the same package class

The SC-06-900 qualifies as a substitute part because it maintains the same filter type, line configuration, voltage ratings, operating temperature range, mounting type, and package configuration as the SC-05-200, while offering different inductance and current specifications within the allowable parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both the SC-05-200 and SC-06-900 maintain Active product status and are ROHS3 compliant, ensuring long-term availability and regulatory compliance for power line filtering applications. The SC-06-900 offers a higher current rating of 6A compared to the SC-05-200's 5A rating, along with a lower maximum DC resistance of 60 mOhm versus 70 mOhm. These characteristics make the SC-06-900 suitable for applications requiring higher current capacity or lower insertion loss. The SC-05-200 remains the appropriate selection for circuits designed specifically for 5A operation with the specified 2 mH inductance at 100 kHz. Both parts share identical voltage ratings, operating temperature ranges, and mounting configurations, ensuring mechanical and thermal compatibility within the same circuit board layout.

Frequently Asked Questions (FAQ)

Q: Can the SC-06-900 be used as a direct replacement for the SC-05-200?

A: The SC-06-900 shares the same mounting type, package configuration, voltage ratings, and operating temperature range as the SC-05-200. However, the inductance values differ (9 mH @ 1 kHz versus 2 mH @ 100 kHz), and the current rating is higher (6A versus 5A). Circuit-level analysis is required to determine if the different inductance specification is compatible with the intended application.

Q: What are the key differences between these two parts?

A: The primary differences are inductance value and frequency specification, current rating, and DC resistance. The SC-06-900 provides higher current capacity and lower DC resistance, while the SC-05-200 is specified for lower inductance at a higher frequency.

Q: Are both parts suitable for the same voltage and temperature operating conditions?

A: Yes. Both the SC-05-200 and SC-06-900 are rated for 250V DC/AC operation and function across the identical temperature range of -40°C to 105°C.

Q: Do these parts use the same footprint?

A: Both parts use through-hole mounting with a Vertical, No Base, 4 PC Pin package configuration. Physical dimensions differ slightly, with the SC-06-900 measuring 1.339" diameter compared to the SC-05-200's 1.260" diameter.

Q: Are both parts RoHS compliant?

A: Yes. Both the SC-05-200 and SC-06-900 are ROHS3 compliant and maintain Active product status.
