Key Parameters

Substitute Part Grouping Explanation

The MLF1005GR68KT qualifies as a direct substitute based on the following critical parameters:

Inductance value matches exactly at 680 nH with identical ±10% tolerance. The shielded multilayer ferrite core construction is identical. Package and physical dimensions are identical (0402/1005 Metric, 1.00mm × 0.50mm × 0.55mm max height). DC resistance specification remains at 550 mOhm maximum. Self resonant frequency is identical at 150 MHz. Both components are RoHS3 compliant with MSL 1 (Unlimited) rating and identical ECCN/HTSUS classifications.

The substitute part demonstrates improved electrical performance (45 mA vs 40 mA current rating, Q factor of 30 vs 25 @ 10MHz) and extended operating temperature range (-55°C to 125°C vs -40°C to 85°C), while maintaining full backward compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

The MLF1005GR68KT is the appropriate substitute for MLF1005LR68KT applications. The original part carries Not For New Designs status, while the substitute maintains Active product status from TDK Corporation, ensuring continued availability and manufacturing support.

Both components satisfy identical electrical specifications for inductance, tolerance, DC resistance, and frequency characteristics. The substitute provides enhanced current handling capability (45 mA vs 40 mA) and extended temperature operating range (-55°C to 125°C vs -40°C to 85°C), delivering superior performance margins without compromising the original design intent.

Compliance certifications are equivalent: both are RoHS3 compliant, REACH unaffected, with identical MSL 1 ratings and ECCN/HTSUS classifications. Physical footprint and mounting characteristics are identical, enabling direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can MLF1005GR68KT replace MLF1005LR68KT in existing designs?

A: Yes. The substitute part maintains identical inductance (680 nH), tolerance (±10%), DC resistance (550 mOhm max), shielding, package (0402/1005 Metric), and frequency characteristics (150 MHz self resonant frequency). All critical electrical parameters match the original specification.

Q: What are the differences between these parts?

A: The substitute offers improved current rating (45 mA vs 40 mA), higher Q factor (30 vs 25 @ 10MHz), and extended operating temperature range (-55°C to 125°C vs -40°C to 85°C). The original part is Not For New Designs; the substitute is Active status.

Q: Are the physical dimensions identical?

A: Yes. Both components use 0402 (1005 Metric) package with identical dimensions: 1.00mm length × 0.50mm width × 0.55mm maximum seated height. Direct PCB footprint compatibility is confirmed.

Q: Do compliance certifications match?

A: Yes. Both parts are RoHS3 compliant, REACH unaffected, with MSL 1 (Unlimited) moisture sensitivity rating. ECCN and HTSUS classifications are identical.

Q: Which part should be selected for new production?

A: MLF1005GR68KT should be selected for new production due to Active product status and superior performance characteristics. The original MLF1005LR68KT is designated Not For New Designs.
