Substitute Part Grouping Explanation

Substitution of the MLF1608DR10MTD25 is determined by strict equivalence across the following critical parameters:

• Inductance Value: 100 nH (exact match required)
• Current Rating: 200 mA minimum
• Package / Case: 0603 (1608 Metric) form factor
• Shielding Type: Shielded construction
• Core Material: Ferrite
• Operating Temperature Range: -55°C to 125°C minimum
• Mounting Type: Surface Mount

The substitute part CS160808-R10K from Bourns Inc. meets all critical substitution criteria. While it features improved DC resistance (250 mOhm Max versus 350 mOhm Max) and higher Q factor (30 @ 25MHz versus 15 @ 25MHz), these represent performance enhancements rather than deviations from the original specification.

Parameter Comparison

Engineering Selection Recommendations

Both the MLF1608DR10MTD25 and CS160808-R10K are active products with full compliance to ROHS3, REACH Unaffected status, and identical export classifications (EAR99, HTSUS 8504.50.8000). The Bourns CS160808-R10K substitute offers superior electrical performance through lower DC resistance and higher Q factor, making it suitable for applications where power efficiency and signal integrity are prioritized. The TDK MLF1608DR10MTD25 remains the primary choice when AEC-Q200 automotive qualification is a mandatory requirement. Both components share identical mechanical footprints and thermal operating ranges, ensuring direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can CS160808-R10K replace MLF1608DR10MTD25 in all applications?

A: Yes, the CS160808-R10K meets all critical electrical and mechanical substitution criteria. The improved DC resistance (250 mOhm versus 350 mOhm) and higher Q factor represent performance enhancements. However, if AEC-Q200 automotive qualification is mandatory for your application, the original MLF1608DR10MTD25 must be used.

Q: Are there physical compatibility concerns between these parts?

A: No. Both components use identical 0603 (1608 Metric) packaging with matching dimensions (0.063" L x 0.031" W) and seated height (0.037" maximum). PCB footprints and assembly processes are directly interchangeable.

Q: What is the significance of the inductance tolerance difference?

A: The CS160808-R10K features ±10% tolerance compared to the MLF1608DR10MTD25's ±20% tolerance. This tighter tolerance provides more predictable circuit performance and reduces design margin requirements in precision applications.

Q: How do the self-resonant frequencies affect circuit design?

A: The MLF1608DR10MTD25 has a self-resonant frequency of 450 MHz, while the CS160808-R10K operates at 240 MHz. For applications operating below 240 MHz, both parts are suitable. For circuits requiring operation closer to 450 MHz, the TDK part provides extended frequency range.

Q: Are both parts suitable for high-temperature automotive environments?

A: Both components operate across -55°C to 125°C and are ROHS3 compliant. The MLF1608DR10MTD25 carries AEC-Q200 qualification, which is the automotive industry standard. The CS160808-R10K does not list AEC-Q200 certification in the provided specifications.
