Substitute Part Grouping Explanation

The UT2020-003 is identified as a parametric equivalent to the UT2024-008 based on the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

  • Identical inductance specification: 2.5 mH @ 10 kHz
  • Identical number of lines: 2
  • Identical current rating: 700mA maximum
  • Identical DC resistance: 400mOhm maximum
  • Identical AC voltage rating: 250V
  • Identical operating temperature range: -20°C ~ 105°C
  • Identical filter type classification: Power Line

Mechanical Compatibility Criteria:

  • Identical mounting type: Through Hole
  • Identical package configuration: Horizontal, 4 PC Pin
  • Both components maintain the same pin count and footprint compatibility

Compliance Equivalence:

  • Both parts hold identical certifications: CSA, IEC, UL
  • Both parts maintain ROHS3 compliance
  • Both parts carry identical ECCN and HTSUS classifications

Substitution is valid when the above parameters match exactly. Physical dimensions vary between the two parts; however, both maintain through-hole mounting compatibility with standard PCB layouts designed for 4-pin horizontal common mode chokes.

Engineering Selection Recommendations

Both the UT2024-008 and UT2020-003 are active production components from Triad Magnetics with identical electrical specifications and certifications. Selection between these parts is based on the following engineering criteria:

Electrical Performance: Both parts deliver identical inductance, current handling, DC resistance, and voltage ratings. No electrical performance differentiation exists between the two components.

Compliance & Certification: Both parts carry CSA, IEC, and UL approvals and maintain ROHS3 compliance status. Both are classified under identical ECCN and HTSUS codes, ensuring equivalent regulatory standing.

Physical Integration: While dimensional differences exist between the two parts, both maintain through-hole mounting with horizontal 4-pin package configuration. PCB layout compatibility depends on specific footprint requirements of the target application. The UT2024-008 occupies a smaller footprint (18.49mm x 22.99mm x 23.50mm height) compared to the UT2020-003 (22.99mm x 24.51mm x 20.00mm height). Design layouts must accommodate the selected part's specific dimensions.

Inventory & Availability: Selection may be influenced by current stock levels. The UT2024-008 maintains 1102 pieces in inventory, while the UT2020-003 maintains 716 pieces.

Frequently Asked Questions (FAQ)

Q: Can UT2020-003 be used as a direct replacement for UT2024-008 in existing designs?

A: Yes, from an electrical standpoint. Both parts share identical inductance (2.5 mH @ 10 kHz), current rating (700mA), DC resistance (400mOhm), voltage rating (250V AC), and operating temperature range (-20°C ~ 105°C). However, physical dimensions differ. The UT2024-008 measures 18.49mm x 22.99mm x 23.50mm height, while the UT2020-003 measures 22.99mm x 24.51mm x 20.00mm height. PCB layout verification is required to confirm footprint compatibility before implementation.

Q: Are both parts certified for the same applications?

A: Yes. Both the UT2024-008 and UT2020-003 hold identical certifications from CSA, IEC, and UL. Both maintain ROHS3 compliance and carry the same ECCN and HTSUS classifications, making them equivalent for regulatory and compliance purposes.

Q: What is the primary difference between these two parts?

A: The primary difference is physical packaging dimensions. Both parts are 2-line common mode chokes with identical electrical specifications, but they occupy different board space. The UT2024-008 is more compact in length and width but taller, while the UT2020-003 is larger in footprint but shorter in height.

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

A: Selection depends on the specific constraint. For applications with limited horizontal board space, the UT2024-008 (18.49mm x 22.99mm) is preferable. For applications with limited vertical clearance, the UT2020-003 (20.00mm height) is preferable. Both parts maintain identical electrical performance.

Q: Are there any performance differences in filtering characteristics?

A: No. Both parts deliver identical inductance at 10 kHz (2.5 mH) and identical DC resistance (400mOhm). Common mode filtering performance is equivalent across both components.

Q: Can these parts be used interchangeably in production?

A: Electrical interchangeability is confirmed. Production interchangeability requires PCB layout verification to ensure the selected part's dimensions fit the target footprint. Once footprint compatibility is confirmed, parts may be used interchangeably from an electrical and compliance standpoint.
