SC-10-D050 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The SC-10-D050 is a 50 µH Common Mode Choke (CMC) manufactured by KEMET, designed for power line filtering applications. This through-hole component operates at 10A maximum current with a DC resistance of 16 mOhm and is rated for 250V DC/AC operation across an extended temperature range of -40°C to 105°C. The part is currently Active in product status and maintains full RoHS3 compliance. Substitute parts are identified when inventory constraints, lead time requirements, or application-specific parameter adjustments necessitate alternative component selection within the same functional category.

Substitute Part Grouping Explanation

Substitute parts for the SC-10-D050 are identified based on strict adherence to the following allowed electrical and mechanical parameters:

Primary Substitution Criteria:

• Filter Type: Power Line
• Number of Lines: 2 (dual-line common mode configuration)
• Mounting Type: Through Hole
• Package / Case: Horizontal, No Base, 4 PC Pin
• Voltage Rating: 250V DC and 250V AC minimum
• Operating Temperature Range: -40°C to 105°C minimum
• RoHS3 Compliance: Required

Secondary Parameter Flexibility:

• Inductance @ 100 kHz: Allowable variation based on circuit design requirements
• Current Rating (Max): Equal or greater than application requirement
• DC Resistance (Max): Acceptable within thermal and efficiency constraints
• Physical Dimensions: Variation permitted within board layout constraints

The SC-12-300 qualifies as a parametric equivalent based on matching all primary substitution criteria while providing increased current capacity (12A vs. 10A) and higher inductance value (3 mH vs. 50 µH).

Parameter Comparison

Engineering Selection Recommendations

Both SC-10-D050 and SC-12-300 maintain Active product status with full RoHS3 compliance and REACH Unaffected designation, ensuring long-term availability and regulatory conformance. Selection between these parts is determined by application-specific requirements:

SC-10-D050 Selection Criteria:

• Applications requiring 50 µH inductance at 100 kHz
• Current requirements up to 10A
• Compact form factor with 34.00 mm diameter and 23.00 mm height
• Lower DC resistance priority (16 mOhm)

SC-12-300 Selection Criteria:

• Applications requiring 3 mH inductance at 100 kHz
• Current requirements between 10A and 12A
• Larger form factor acceptable (49.00 mm diameter and 28.00 mm height)
• Higher current capacity with acceptable DC resistance (18 mOhm)

Both parts satisfy identical voltage ratings (250V DC/AC), temperature operating range (-40°C to 105°C), and mechanical mounting specifications (through-hole, horizontal orientation, 4-pin configuration). Component selection must align with circuit inductance requirements and available board space.

Frequently Asked Questions (FAQ)

Q: Can SC-12-300 directly replace SC-10-D050 in any application?

A: Direct replacement is not universal. While both parts share identical voltage ratings, temperature ranges, and mounting configurations, the SC-12-300 provides significantly higher inductance (3 mH vs. 50 µH). Substitution is valid only when the application circuit design accommodates the higher inductance value. Circuit simulation or testing is required to confirm performance equivalence.

Q: What are the physical dimension differences between these parts?

A: SC-10-D050 measures 34.00 mm diameter with 23.00 mm maximum height. SC-12-300 measures 49.00 mm diameter with 28.00 mm maximum height. Both use identical package configuration (Horizontal, No Base, 4 PC Pin). Board layout space must accommodate the larger SC-12-300 footprint.

Q: Are both parts RoHS3 compliant?

A: Yes. Both SC-10-D050 and SC-12-300 are ROHS3 Compliant with REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: What is the difference in DC resistance between these parts?

A: SC-10-D050 has a maximum DC resistance of 16 mOhm, while SC-12-300 has a maximum DC resistance of 18 mOhm. This 2 mOhm difference results in minimal thermal impact in most power line filtering applications.

Q: Can the SC-12-300 handle higher current than SC-10-D050?

A: Yes. SC-12-300 is rated for 12A maximum current compared to SC-10-D050 at 10A maximum current. Applications requiring current capacity above 10A benefit from SC-12-300 selection.

Q: Are both parts available in the same packaging format?

A: Yes. Both parts are supplied in Bulk packaging with identical through-hole mounting configuration and 4-pin horizontal orientation without base.
