Substitute Part Grouping Explanation

Substitute parts for the MLF1608DR82KTD25 are qualified based on the following criteria:

• Identical inductance value: 820 nH with ±10% tolerance
• Identical package and form factor: 0603 (1608 Metric) surface mount
• Identical core material: Ferrite shielded construction
• DC resistance not exceeding 1.4 Ohm maximum
• Operating temperature range encompassing -55°C to 125°C
• Current rating equal to or greater than 70 mA
• Identical mounting type: Surface mount
• Compliance with ROHS3 and REACH requirements

The CS160808-R82K from Bourns Inc. meets all substitution criteria with enhanced current rating capability.

Parameter Comparison

Engineering Selection Recommendations

Both the MLF1608DR82KTD25 and CS160808-R82K are active production components with full ROHS3 compliance and REACH unaffected status. The MLF1608DR82KTD25 carries AEC-Q200 automotive qualification. The CS160808-R82K provides equivalent electrical and mechanical performance with a higher current rating of 100 mA compared to the 70 mA specification of the original part. Selection between these components should be based on availability, supply chain requirements, and specific application current demands within the qualified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can the CS160808-R82K be used as a direct replacement for the MLF1608DR82KTD25?

A: Yes. Both components share identical inductance (820 nH), tolerance (±10%), DC resistance (1.4 Ohm max), package (0603/1608 Metric), shielding type (ferrite shielded), and operating temperature range (-55°C to 125°C). The CS160808-R82K has a higher current rating (100 mA vs. 70 mA), which does not prevent substitution in applications requiring 70 mA or less.

Q: Are there any package or footprint differences between these parts?

A: No. Both components use the identical 0603 (1608 Metric) surface mount package with dimensions of 0.063" L x 0.031" W (1.60mm x 0.80mm) and maximum seated height of 0.037" (0.95mm). PCB footprints are interchangeable.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 compliant and REACH unaffected. The MLF1608DR82KTD25 additionally carries AEC-Q200 automotive qualification. Both have Moisture Sensitivity Level 1 (Unlimited).

Q: How do the Q factor specifications differ?

A: The MLF1608DR82KTD25 specifies Q @ 25MHz as 15, while the CS160808-R82K specifies Q @ 25MHz as 30. The CS160808-R82K exhibits higher quality factor at the test frequency.

Q: Are the self-resonant frequencies equivalent?

A: The MLF1608DR82KTD25 has a self-resonant frequency of 130 MHz, while the CS160808-R82K has 75 MHz. Both values remain within acceptable ranges for typical 820 nH inductor applications in the 0603 package class.
