Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLF1608DR56MTD25 is determined by the following critical parameters:

• Inductance Value: Must be 560 nH (primary matching criterion)
• Package Dimensions: Must be 0603 (1608 Metric) for PCB compatibility
• Shielding Type: Must be shielded to maintain electromagnetic isolation
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Mounting Type: Must be surface mount compatible
• RoHS Compliance: Must meet ROHS3 requirements

The substitute part CS160808-R56K from Bourns Inc. meets all these criteria. While the substitute exhibits improved electrical characteristics (lower DCR at 900 mOhm, higher current rating at 150 mA, and tighter tolerance at ±10%), these represent performance enhancements rather than deviations from the core substitution parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the MLF1608DR56MTD25 and CS160808-R56K are active production components with ROHS3 compliance and unlimited moisture sensitivity rating. The MLF1608DR56MTD25 carries AEC-Q200 automotive qualification, which may be a requirement for specific applications. The CS160808-R56K substitute provides superior electrical performance with lower DC resistance, higher current capacity, and improved Q factor, making it suitable for applications where these enhancements are beneficial or neutral to circuit operation. Selection between these parts should be based on specific application requirements, including automotive qualification necessity and performance margin requirements.

Frequently Asked Questions (FAQ)

Q: Can CS160808-R56K replace MLF1608DR56MTD25 in all applications?

A: Both parts share identical inductance values, package dimensions, and operating temperature ranges. The substitute exhibits improved electrical characteristics. Compatibility depends on whether the application requires AEC-Q200 automotive qualification; the TDK part carries this rating while the Bourns part does not list this certification.

Q: What is the significance of the different DC resistance values?

A: The MLF1608DR56MTD25 has a maximum DC resistance of 1.05 Ohm, while the CS160808-R56K is rated at 900 mOhm maximum. Lower DC resistance reduces power dissipation and heat generation in the inductor. This difference may be significant in high-current or thermally constrained applications.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 0603 (1608 Metric) package with dimensions of 0.063" L x 0.031" W (1.60mm x 0.80mm) and a maximum seated height of 0.037" (0.95mm). They are mechanically interchangeable on PCBs designed for this footprint.

Q: What does the inductance tolerance difference mean for circuit design?

A: The MLF1608DR56MTD25 has ±20% tolerance while the CS160808-R56K has ±10% tolerance. Tighter tolerance in the substitute part provides more predictable inductance values, which may improve circuit performance consistency across production batches.

Q: Are both parts suitable for high-frequency applications?

A: Both parts are shielded multilayer inductors with self-resonant frequencies in the range of 95–170 MHz. The MLF1608DR56MTD25 has a higher self-resonant frequency (170 MHz), which may provide better performance at higher frequencies. Application suitability depends on specific frequency requirements.
