SC-07-04GJ Common Mode Choke Equivalent & Substitute Parts

Part Overview

The SC-07-04GJ is a 360 µH Common Mode Choke (CMC) manufactured by KEMET, designed for power line filtering applications. This through-hole component operates at 7A maximum current with a DC resistance of 14mOhm and is rated for 250V DC/AC operation across an operating temperature range of -40°C to 120°C. The part is currently active in production and ROHS3 compliant, making it suitable for modern electronic equipment requiring EMI suppression in two-line configurations.

Substitute parts are identified when equivalent electrical performance can be achieved within the allowed parameter tolerances for the application, considering current rating, inductance characteristics, voltage ratings, and physical mounting compatibility.

Key Parameters

Substitute Part Grouping Explanation

The SC-08-E075J qualifies as a parametric equivalent based on the following criteria:

• Voltage Compatibility: Both parts maintain 250V DC and 250V AC ratings, ensuring electrical safety in the same circuit applications
• Mounting Configuration: Both use through-hole mounting with vertical, 4-pin package orientation, allowing direct PCB footprint compatibility
• Operating Temperature Range: Both support -40°C to 120°C operation, maintaining thermal performance across identical environmental conditions
• Compliance Standards: Both are ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements
• Current Rating Tolerance: The SC-08-E075J provides 8A maximum current, exceeding the 7A requirement of the SC-07-04GJ, allowing operation within safe margins
• DC Resistance Performance: The SC-08-E075J exhibits 12.7mOhm DCR, which is lower than the 14mOhm specification, reducing power dissipation

The primary difference lies in inductance specification (750 µH @ 10 kHz versus 360 µH @ 100 kHz) and physical dimensions. Selection between these parts depends on circuit inductance requirements at the operating frequency.

Parameter Comparison

Engineering Selection Recommendations

Both SC-07-04GJ and SC-08-E075J are active production parts with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future applications.

The SC-08-E075J provides enhanced current handling capacity (8A versus 7A) and improved DC resistance characteristics (12.7mOhm versus 14mOhm), resulting in lower thermal dissipation. However, the increased physical dimensions (25.00mm length and 25.50mm height versus 18.00mm and 20.00mm) require verification of available PCB space.

Selection should be based on circuit inductance requirements at the operating frequency. The SC-07-04GJ operates at 360 µH @ 100 kHz, while the SC-08-E075J operates at 750 µH @ 10 kHz. These different frequency characteristics affect filtering performance in specific application bands.

Frequently Asked Questions (FAQ)

Q: Can SC-08-E075J directly replace SC-07-04GJ on the same PCB?

A: Physical footprint compatibility exists due to identical mounting type (through-hole, vertical 4-pin configuration) and matching voltage/temperature ratings. However, the SC-08-E075J is larger (25.00mm x 16.00mm x 25.50mm versus 18.00mm x 17.00mm x 20.00mm), requiring verification that PCB layout accommodates the increased dimensions.

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

A: The SC-08-E075J provides higher inductance (750 µH @ 10 kHz) compared to SC-07-04GJ (360 µH @ 100 kHz), operates at a different frequency characteristic, and offers superior current capacity (8A versus 7A) with lower DC resistance (12.7mOhm versus 14mOhm).

Q: Are both parts compliant with current regulatory standards?

A: Both SC-07-04GJ and SC-08-E075J are ROHS3 compliant and REACH unaffected, meeting modern electronic equipment regulatory requirements.

Q: Which part should be selected for space-constrained applications?

A: The SC-07-04GJ maintains smaller physical dimensions (18.00mm x 17.00mm x 20.00mm) and is suitable for applications with limited PCB space. The SC-08-E075J requires additional clearance due to its larger footprint.

Q: How do the frequency characteristics affect application suitability?

A: The SC-07-04GJ operates at 100 kHz frequency, while SC-08-E075J operates at 10 kHz. Circuit design specifications determine which frequency characteristic aligns with the required filtering performance for the target application.
