Parameter Comparison

Engineering Selection Recommendations

Würth Elektronik 7447962 is the primary component choice when maximum current handling capacity of 825 mA is required within the 0603 package form factor. This unshielded multilayer inductor provides the specified performance envelope with active product status and full regulatory compliance.

Bourns CS160808-R10K serves as an equivalent substitute when the application current requirement does not exceed 200 mA. This shielded variant offers superior Q factor performance (30 @ 25 MHz versus 15 @ 25 MHz) and lower DC resistance (250 mOhm Max versus 500 mOhm Max). The shielded construction provides electromagnetic isolation benefits in noise-sensitive applications. Both components maintain identical inductance tolerance, operating temperature range, and regulatory compliance certifications.

Selection between these components depends on application-specific current requirements and electromagnetic environment considerations. Both maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with standard surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the Bourns CS160808-R10K replace the Würth Elektronik 7447962 in all applications?

A: The Bourns CS160808-R10K is suitable for applications where the circuit current does not exceed 200 mA. The Würth component supports up to 825 mA. If your application requires current handling above 200 mA, the Würth Elektronik 7447962 is the required choice.

Q: What is the difference between shielded and unshielded inductors?

A: The Würth Elektronik 7447962 is unshielded, while the Bourns CS160808-R10K is shielded. Shielded inductors provide electromagnetic isolation and reduce coupling to adjacent circuit elements. Unshielded inductors occupy less board space and typically exhibit lower DC resistance.

Q: Are both components compatible with standard 0603 package assembly equipment?

A: Yes. Both components use the 0603 (1608 Metric) package form factor with identical length and width dimensions (1.60mm x 0.80mm). Height difference is minimal (1.00mm versus 0.95mm), presenting no assembly compatibility issues.

Q: Do both parts meet current environmental and regulatory requirements?

A: Yes. Both the Würth Elektronik 7447962 and Bourns CS160808-R10K are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings. Both are suitable for standard surface mount assembly and storage conditions.

Q: What is the significance of Q factor difference between these components?

A: The Bourns CS160808-R10K exhibits Q factor of 30 @ 25 MHz compared to 15 @ 25 MHz for the Würth component. Higher Q factor indicates lower energy loss at the test frequency. This characteristic may provide performance advantages in high-frequency filtering or resonant circuit applications.

Q: Are the inductance values and tolerances identical?

A: Yes. Both components provide 100 nH inductance with ±10% tolerance and identical self-resonant frequency of 240 MHz. Inductance matching ensures direct functional equivalence in circuit designs.
