UT2024-007 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The UT2024-007 is a 2-line common mode choke manufactured by Triad Magnetics, designed for power line filtering applications. This through-hole component operates at 4.5 mH inductance at 10 kHz with a maximum current rating of 600mA and 750mOhm DC resistance. The part is currently active in production with full compliance to RoHS3, CSA, IEC, and UL standards. Substitute parts are identified when inventory constraints, lead time requirements, or application-specific parameter needs necessitate alternative component selection while maintaining functional compatibility within specified electrical and mechanical tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the UT2024-007 is based on the following critical parameters that define functional compatibility:

Mandatory Matching Parameters:

• Filter Type: Power Line
• Number of Lines: 2
• Mounting Type: Through Hole
• Package / Case: Horizontal, 4 PC Pin
• Voltage Rating - AC: 250V
• Operating Temperature Range: -20°C ~ 105°C
• Approval Agencies: CSA, IEC, UL compliance

Allowable Parameter Variations:

• Inductance @ 10 kHz: Higher values acceptable if application permits increased filtering
• Current Rating (Max): Higher ratings acceptable for design margin
• DC Resistance (Max): Equal or lower values acceptable
• Physical dimensions: Variations permitted within through-hole PCB footprint compatibility

The ET2424-013 qualifies as a parametric equivalent because it maintains all mandatory matching parameters while providing increased inductance (9.2 mH vs 4.5 mH), higher current capacity (700mA vs 600mA), and identical DC resistance (750mOhm). These variations represent design enhancements suitable for applications requiring greater filtering capability or higher current handling.

Parameter Comparison

Engineering Selection Recommendations

Both the UT2024-007 and ET2424-013 maintain active product status with identical regulatory compliance certifications (CSA, IEC, UL) and RoHS3 compliance. Selection between these components is determined by application-specific electrical requirements rather than compliance or availability factors.

UT2024-007 Selection Criteria:

• Applications requiring 4.5 mH inductance at 10 kHz
• Circuits designed for 600mA maximum current
• Existing PCB layouts with component placement optimized for 0.728" L x 0.905" W dimensions

ET2424-013 Selection Criteria:

• Applications requiring 9.2 mH inductance at 10 kHz for enhanced filtering
• Circuits requiring 700mA current capacity
• New designs where increased component size (1.043" L x 1.043" W) accommodates PCB layout requirements

Both parts operate across the identical temperature range (-20°C ~ 105°C) and maintain 250V AC voltage rating. DC resistance remains constant at 750mOhm maximum, ensuring equivalent power dissipation characteristics. Physical dimension differences must be evaluated against PCB footprint availability and thermal management requirements.

Frequently Asked Questions (FAQ)

Q: Can ET2424-013 directly replace UT2024-007 in existing designs?

A: Physical substitution is possible due to identical mounting type (through-hole), package configuration (horizontal, 4 PC pin), and pin count. However, the increased inductance (9.2 mH vs 4.5 mH) and larger physical dimensions (1.043" x 1.043" vs 0.728" x 0.905") require PCB layout verification. Electrical circuit behavior will change due to higher inductance, which may affect filtering characteristics and frequency response.

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

A: The primary differences are inductance value (9.2 mH vs 4.5 mH), current rating (700mA vs 600mA), and physical size. DC resistance, voltage rating, temperature range, and regulatory compliance are identical. The ET2424-013 provides approximately 2x the inductance with 16.7% higher current capacity.

Q: Are both parts suitable for 250V AC power line applications?

A: Yes. Both UT2024-007 and ET2424-013 carry 250V AC voltage rating and hold identical approval certifications (CSA, IEC, UL) for power line filtering applications.

Q: What is the impact of different inductance values on circuit performance?

A: Inductance directly affects filtering attenuation and frequency response. Higher inductance (ET2424-013 at 9.2 mH) provides greater common mode noise rejection at the expense of increased component size and potential impedance effects at higher frequencies. Selection depends on specific EMI filtering requirements of the application.

Q: Are there physical space constraints to consider?

A: Yes. The ET2424-013 is larger (1.043" x 1.043" x 0.906" height) compared to UT2024-007 (0.728" x 0.905" x 0.925" height). PCB layout must accommodate these dimensions. Both maintain identical through-hole mounting and 4-pin horizontal configuration.

Q: Do both parts have identical environmental compliance?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and hold identical regulatory approvals (CSA, IEC, UL). Operating temperature range is identical (-20°C ~ 105°C). Moisture sensitivity level is not applicable for both components.
