Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalent:

The Würth Elektronik 744824101 is a direct parametric equivalent to the 744824801. Both parts share identical electrical specifications (1 mH @ 10 kHz, 10A current rating, 7 mOhm DCR) and physical dimensions. Both are RoHS3 compliant and REACH Unaffected. This substitute is suitable for direct replacement in applications where the original part number is unavailable.

Parametric Alternatives with Higher Current Capacity:

The EPCOS B82724V2123U040 offers 1.5 mH inductance at 10 kHz with a 12A current rating and 6.3 mOhm DCR. This part is suitable for applications requiring higher current handling capacity while maintaining similar inductance characteristics. The part is RoHS3 compliant and REACH Unaffected. Physical dimensions are larger (33.00mm x 23.00mm x 30.00mm height).

The ITG Electronics C201367A-102NHF provides 1 mH inductance at 10 kHz with a 12A current rating and 8 mOhm DCR. This part matches the inductance specification of the original part while offering increased current capacity. The part is RoHS Compliant and REACH Unaffected. Physical dimensions are 31.50mm x 23.50mm x 30.00mm height.

Parametric Alternative with Higher Inductance:

The EPCOS B82725V2103U040 offers 5 mH inductance at 10 kHz with an 11.5A current rating and 8.2 mOhm DCR. This part is suitable for applications requiring higher inductance values for enhanced EMI filtering. The part is RoHS3 compliant but is REACH Affected. Physical dimensions are larger (39.00mm x 23.00mm x 37.00mm height).

All substitute parts maintain the mandatory specifications: 2-line configuration, through-hole mounting, vertical 4-pin package, 250V AC voltage rating, and -40°C to 125°C operating temperature range. Selection should be based on specific application requirements for inductance, current capacity, and physical space constraints.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 744824101 be used as a direct replacement for the 744824801?

A: Yes. The 744824101 is a direct parametric equivalent with identical electrical specifications (1 mH @ 10 kHz, 10A, 7 mOhm DCR) and physical dimensions. Both parts are RoHS3 compliant and REACH Unaffected, making them interchangeable for the same application.

Q: What is the difference between the EPCOS B82724V2123U040 and the original 744824801?

A: The B82724V2123U040 has a higher inductance value (1.5 mH versus 1 mH) and higher current rating (12A versus 10A). The DC resistance is lower (6.3 mOhm versus 7 mOhm). Physical dimensions are larger. This part is suitable for applications requiring higher current capacity or slightly higher inductance filtering characteristics.

Q: Can I use the EPCOS B82725V2103U040 as a substitute if my application requires 1 mH inductance?

A: No. The B82725V2103U040 provides 5 mH inductance, which is significantly higher than the 1 mH specification of the original part. This higher inductance will alter the frequency response and filtering characteristics of the circuit. This part is suitable only for applications specifically designed for 5 mH inductance.

Q: Are all substitute parts RoHS3 compliant?

A: The Würth Elektronik 744824801, 744824101, and EPCOS B82724V2123U040 and B82725V2103U040 are RoHS3 compliant. The ITG Electronics C201367A-102NHF is RoHS Compliant but not specifically RoHS3 certified. Verify compliance requirements for your specific application.

Q: What is the REACH status of these parts?

A: The Würth Elektronik 744824801, 744824101, EPCOS B82724V2123U040, and ITG Electronics C201367A-102NHF are REACH Unaffected. The EPCOS B82725V2103U040 is REACH Affected. Confirm REACH compliance requirements for your application jurisdiction.

Q: Do all substitute parts have the same physical dimensions?

A: No. The Würth Elektronik 744824801 and 744824101 share identical dimensions (27.50mm x 18.50mm x 33.00mm height). The EPCOS B82724V2123U040 is 33.00mm x 23.00mm x 30.00mm. The EPCOS B82725V2103U040 is 39.00mm x 23.00mm x 37.00mm. The ITG Electronics C201367A-102NHF is 31.50mm x 23.50mm x 30.00mm. Verify PCB layout space availability before selecting a substitute with different dimensions.

Q: Which substitute part has the lowest DC resistance?

A: The EPCOS B82724V2123U040 has the lowest DC resistance at 6.3 mOhm, compared to 7 mOhm for the original 744824801. Lower DC resistance reduces power dissipation in the component.

Q: Can I use the ITG Electronics C201367A-102NHF as a direct replacement?

A: The C201367A-102NHF matches the 1 mH inductance specification and provides a higher current rating (12A versus 10A). However, the DC resistance is slightly higher (8 mOhm versus 7 mOhm), and physical dimensions differ (31.50mm x 23.50mm x 30.00mm versus 27.50mm x 18.50mm x 33.00mm). Verify PCB layout compatibility and acceptable DC resistance limits for your application.

Q: What is the primary criterion for selecting a substitute common mode choke?

A: The inductance value at the specified frequency (10 kHz) is the primary criterion. The original part specifies 1 mH @ 10 kHz. Substitutes with different inductance values will alter circuit filtering characteristics. Current rating and DC resistance are secondary criteria that must meet or exceed application requirements.
