Key Parameters

Substitute Part Grouping Explanation

Substitution of the Würth Elektronik 744050200047 is determined by the following critical parameters:

• Inductance Value: 470 nH nominal with tolerance band overlap
• Current Rating: Minimum 2.2 A continuous current capability
• DC Resistance: Maximum 49 mOhm to maintain thermal and efficiency characteristics
• Saturation Current: Minimum 4.7 A to prevent core saturation under transient conditions
• Shielding Configuration: Semi-shielded topology for EMI containment
• Core Material: Ferrite construction for frequency response characteristics
• Operating Temperature: -40°C to 125°C range compatibility
• Mounting: Surface mount configuration on nonstandard SMD package
• Physical Dimensions: Compatible footprint within 2.00 mm × 1.60 mm × 1.00 mm envelope

The Eaton SDCL1V2010-R47N-R meets these substitution criteria within the allowed parameter windows for this product category.

Parameter Comparison

Engineering Selection Recommendations

Both the Würth Elektronik 744050200047 and Eaton SDCL1V2010-R47N-R are active products with current manufacturing status. Both components maintain RoHS and REACH compliance. The Eaton substitute exhibits acceptable parameter variance within the electrical and mechanical windows defined for this inductor category. Physical dimensions of the Eaton part are marginally larger but remain compatible with nonstandard SMD footprints. Selection between these parts is based on availability, lead time, and application-specific saturation margin requirements.

Frequently Asked Questions (FAQ)

Q: Can the Eaton SDCL1V2010-R47N-R directly replace the Würth Elektronik 744050200047 in all applications?

A: Direct substitution is supported for applications where the saturation current margin of 2.4 A is sufficient. The Eaton part exhibits lower saturation current (2.4 A vs. 4.7 A), which may limit performance in circuits requiring higher transient current handling. Verify application peak current requirements before substitution.

Q: What is the impact of the wider inductance tolerance on the Eaton part?

A: The Eaton SDCL1V2010-R47N-R carries ±30% tolerance versus ±20% for the Würth part. This wider tolerance band is acceptable for general-purpose filtering and impedance matching applications. Circuits requiring tighter inductance control should confirm tolerance compatibility with design specifications.

Q: Are there packaging or mounting differences between these parts?

A: Both components use surface mount technology on nonstandard SMD packages. The Eaton part is 0.10 mm larger in length, width, and height. Verify PCB layout clearances and reflow profile compatibility before implementation.

Q: Do both parts meet the same compliance standards?

A: Both components are RoHS compliant and REACH unaffected. The Würth part carries ROHS3 certification while the Eaton part carries standard RoHS certification. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings.

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

A: The Eaton part exhibits 53 mOhm maximum DC resistance compared to 49 mOhm for the Würth part. This 4 mOhm difference results in marginally higher resistive losses and thermal dissipation. For power-critical applications, calculate thermal impact based on circuit current levels.
