KEMET SC-02-50J Common Mode Choke Equivalent & Substitute Parts

Part Overview

The KEMET SC-02-50J is a 5 mH common mode choke (CMC) designed for power line filtering applications. This through-hole mounted component operates at 2A maximum current with 120 mOhm DC resistance and supports dual-line filtering in the SC-J series. The part maintains Active product status with full RoHS3 compliance and operates across the -40°C to 120°C temperature range. Substitute parts are identified within the same SC-J series to provide alternative inductance values while maintaining core electrical and mechanical compatibility parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SC-02-50J are selected based on strict parameter compatibility within the KEMET SC-J series. All substitute parts maintain the following core requirements:

Fixed Parameters (Must Match):

• Number of Lines: 2
• Current Rating: 2A
• Voltage Rating: 250V DC / 250V AC
• Operating Temperature: -40°C to 120°C
• Mounting Type: Through Hole
• Package / Case: Vertical, 4 PC Pin
• Series: SC-J
• Product Status: Active
• RoHS3 Compliance

Variable Parameters (Allowed to Differ):

• Inductance @ 100 kHz: 1 mH, 3 mH, or 5 mH
• DC Resistance: 100 mOhm to 120 mOhm
• Physical Dimensions: Two size variants available

The SC-02-50J substitutes are grouped by inductance value, as this parameter directly determines filtering characteristics while all other electrical and mechanical specifications remain compatible.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status with full RoHS3 compliance and REACH unaffected designation. Selection between SC-02-50J and its substitutes is determined by required inductance value and available board space.

SC-02-10J (1 mH): Lowest inductance option. Maintains identical footprint to SC-02-50J (25.00mm x 20.00mm x 27.00mm) with reduced DC resistance (100 mOhm). Suitable for applications requiring minimal filtering attenuation.

SC-02-30GJ (3 mH): Mid-range inductance with compact footprint (17.50mm x 17.00mm x 20.00mm). Lowest profile option at 20.00mm height. DC resistance 100 mOhm. Applicable where space constraints require reduced component height and length.

SC-02-30J (3 mH): Mid-range inductance with standard footprint (25.00mm x 20.00mm x 27.00mm). DC resistance 110 mOhm. Maintains identical dimensions to SC-02-50J for direct board layout compatibility.

All parts operate within identical voltage (250V DC/AC), current (2A), and temperature (-40°C to 120°C) specifications. Compliance certifications (RoHS3, REACH, EAR99, HTSUS) are uniform across all options.

Frequently Asked Questions (FAQ)

Q: Can SC-02-10J replace SC-02-50J in my application?

A: SC-02-10J is electrically and mechanically compatible with SC-02-50J. Both share identical current rating (2A), voltage rating (250V DC/AC), temperature range (-40°C to 120°C), mounting type (Through Hole), and package configuration (Vertical, 4 PC Pin). The difference is inductance: SC-02-10J provides 1 mH versus SC-02-50J's 5 mH. Substitution is valid only if your circuit design accommodates the lower inductance value.

Q: What is the difference between SC-02-30GJ and SC-02-30J?

A: Both parts provide 3 mH inductance at 100 kHz with 2A current rating and 250V voltage rating. The primary differences are physical dimensions and DC resistance. SC-02-30GJ has a compact footprint (17.50mm x 20.00mm height) with 100 mOhm DCR. SC-02-30J uses the standard footprint (25.00mm x 27.00mm height) with 110 mOhm DCR. Select SC-02-30GJ for space-constrained layouts; select SC-02-30J for standard board designs.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. SC-02-10J, SC-02-30GJ, and SC-02-30J are all RoHS3 compliant with REACH unaffected status, matching SC-02-50J compliance.

Q: Can I use SC-02-30GJ if my PCB layout requires the 25.00mm x 20.00mm footprint?

A: No. SC-02-30GJ has a different footprint (17.50mm x 17.00mm) and reduced height (20.00mm). Use SC-02-30J instead, which maintains the 25.00mm x 20.00mm x 27.00mm dimensions of SC-02-50J.

Q: Do all substitute parts have the same DC resistance?

A: No. SC-02-50J has 120 mOhm maximum DCR. SC-02-10J and SC-02-30GJ have 100 mOhm. SC-02-30J has 110 mOhm. Lower DCR reduces heat dissipation; verify your thermal design accommodates these variations.

Q: What determines which substitute part to select?

A: Selection is based on three criteria: (1) Required inductance value for your filtering application, (2) Available PCB space (footprint and height), and (3) Acceptable DC resistance for thermal performance. All parts maintain identical current, voltage, temperature, and compliance specifications.
