Substitute Part Grouping Explanation

Substitute parts for the UT2020-002 are identified based on the following critical parameters that define functional equivalence within the common mode choke category:

Mandatory Matching Criteria:

• 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 to 105°C
• Approval Agencies: CSA, IEC, UL
• RoHS Status: ROHS3 Compliant

Allowable Parameter Variation:

• Inductance @ 10 kHz: Higher values acceptable for applications requiring increased filtering
• Current Rating (Max): Higher ratings acceptable for applications with increased current demands
• DC Resistance (Max): Maintained at 750mOhm maximum

The ET2424-013 meets all mandatory matching criteria and provides higher inductance (9.2 mH) and increased current capacity (700mA) while maintaining identical DC resistance and all compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the UT2020-002 and ET2424-013 are active production components manufactured by Triad Magnetics with identical compliance certifications (CSA, IEC, UL) and RoHS3 status. Selection between these parts is determined by application-specific electrical requirements:

UT2020-002 Selection Criteria:

• Applications requiring 4.5 mH inductance at 10 kHz
• Circuit designs with maximum current demand of 600mA
• Space-constrained layouts (smaller physical dimensions: 22.99mm L x 24.51mm W x 20.00mm H)

ET2424-013 Selection Criteria:

• Applications requiring higher inductance filtering (9.2 mH at 10 kHz)
• Circuit designs with current demands up to 700mA
• Applications where increased filtering performance justifies larger physical dimensions (26.50mm L x 26.50mm W x 23.00mm H)

Both parts maintain identical DC resistance (750mOhm maximum), AC voltage rating (250V), and operating temperature range (-20°C to 105°C). PCB layout modifications are required due to dimensional differences.

Frequently Asked Questions (FAQ)

Q: Can ET2424-013 be used as a direct replacement for UT2020-002?

A: ET2424-013 is electrically compatible for applications where the higher inductance (9.2 mH vs 4.5 mH) and increased current capacity (700mA vs 600mA) do not create circuit performance issues. Physical dimensions differ, requiring PCB layout verification. Both parts share identical DC resistance, voltage rating, temperature range, and compliance certifications.

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

A: UT2020-002 measures 22.99mm L x 24.51mm W x 20.00mm H. ET2424-013 measures 26.50mm L x 26.50mm W x 23.00mm H. Both use horizontal, 4-pin through-hole packages. PCB footprint verification is required before substitution.

Q: Are both parts RoHS3 compliant?

A: Yes. Both UT2020-002 and ET2424-013 are ROHS3 compliant and hold identical approval certifications from CSA, IEC, and UL.

Q: What is the significance of the 750mOhm DC resistance specification?

A: DC resistance (DCR) of 750mOhm maximum is maintained identically across both parts. This parameter determines power dissipation and voltage drop across the component at rated current. Both parts meet this specification.

Q: Can these parts be used interchangeably in all power line filtering applications?

A: No. Substitution is valid only when the application circuit design accommodates the higher inductance value (9.2 mH) and increased current capacity (700mA) of ET2424-013, and when PCB layout can accommodate the larger physical dimensions. Circuit simulation or testing may be required to confirm performance equivalence for specific applications.
