SC-02-500 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The SC-02-500 is a 5 mH common mode choke manufactured by KEMET, designed for power line filtering applications in two-line configurations. This through-hole component operates at 2A 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 full ROHS3 compliance.

Substitute parts become necessary when the SC-02-500 is unavailable, when design specifications allow for alternative inductance values, or when different DC resistance characteristics are acceptable for the application. All substitute parts listed maintain compatibility with the SC-02 base product family and preserve critical electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC-02-500 is determined by the following criteria:

Critical Parameters (Must Match):

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

Variable Parameters (Allowed to Differ):

• Inductance @ 100 kHz: 1 mH to 5 mH
• DC Resistance (Max): 80 mOhm to 110 mOhm
• Physical Dimensions: Varies by inductance value

All substitute parts listed maintain the SC-02 base product family designation and preserve electrical safety ratings and environmental compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts for the SC-02-500 maintain Active product status and full ROHS3 compliance. Selection among these alternatives depends on application-specific inductance requirements:

For applications requiring 5 mH inductance: The SC-02-500 is the primary selection with 100 mOhm maximum DC resistance.

For applications tolerating lower inductance values: SC-02-300 (3 mH), SC-02-200 (2 mH), SC-02-100 (1 mH), SC-02-101 (1 mH), and SC-02-10GS (1 mH) are electrically qualified substitutes. These parts maintain identical voltage ratings, current capacity, and temperature operating range.

For applications with DC resistance constraints: SC-02-10GS offers the lowest DC resistance at 80 mOhm maximum. SC-02-100 and SC-02-300 maintain 100 mOhm maximum. SC-02-101 and SC-02-200 operate at 110 mOhm maximum.

All substitute parts carry identical REACH and ECCN classifications (REACH Unaffected, EAR99) and are packaged in the same vertical, no-base, 4-pin configuration suitable for through-hole PCB assembly.

Frequently Asked Questions (FAQ)

Q: Can SC-02-100 replace SC-02-500 in my circuit?

A: SC-02-100 is electrically compatible with SC-02-500 in terms of current rating, voltage rating, temperature range, and mounting configuration. However, SC-02-100 provides 1 mH inductance compared to SC-02-500's 5 mH. Substitution is valid only if your application circuit design permits lower inductance filtering characteristics.

Q: What is the difference between SC-02-101 and SC-02-100?

A: Both parts provide 1 mH inductance at 100 kHz and 2A current rating. The primary difference is DC resistance: SC-02-100 specifies 100 mOhm maximum, while SC-02-101 specifies 110 mOhm maximum. SC-02-101 also features a smaller physical footprint (0.512" width versus 0.728" width).

Q: Why does SC-02-10GS have lower DC resistance than other 1 mH options?

A: SC-02-10GS is specified with 80 mOhm maximum DC resistance, compared to 100 mOhm (SC-02-100) and 110 mOhm (SC-02-101). This lower resistance characteristic is a design variation within the SC-02 family and may be selected when minimizing power dissipation is a design requirement.

Q: Are all substitute parts through-hole mounted?

A: Yes. All listed substitute parts use through-hole mounting with vertical orientation, no base, and 4-pin configuration. Physical dimensions vary by inductance value, but mounting compatibility with standard through-hole PCB layouts is maintained across all alternatives.

Q: Do substitute parts maintain the same compliance certifications?

A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Environmental and regulatory compliance is consistent across the SC-02 product family.
