Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLF1005LR47KT is determined by strict equivalence across the following critical parameters: inductance value (470 nH), inductance tolerance (±10%), current rating (50 mA minimum), DC resistance (420 mOhm maximum), shielding type (shielded), package configuration (0402 / 1005 Metric), core material (ferrite), and mounting type (surface mount). The substitute part MLF1005GR47KT meets all these criteria, providing direct functional and mechanical compatibility. Differences in product status, operating temperature range, and quality factor (Q) do not affect substitution eligibility but may influence selection based on application requirements and supply availability.

Parameter Comparison

Engineering Selection Recommendations

The MLF1005GR47KT is the direct equivalent substitute for the MLF1005LR47KT. Both components are manufactured by TDK Corporation and share identical electrical and mechanical specifications across all critical parameters. The MLF1005GR47KT carries an "Active" product status, ensuring ongoing manufacturing support and supply chain availability. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The MLF1005GR47KT provides an extended operating temperature range (-55°C to 125°C) compared to the MLF1005LR47KT (-40°C to 85°C), offering greater thermal flexibility for demanding environments. The improved quality factor (Q = 30 @ 10MHz versus Q = 25 @ 10MHz) in the substitute part represents a performance enhancement without compromising compatibility.

Frequently Asked Questions (FAQ)

Q: Can MLF1005GR47KT be used as a direct replacement for MLF1005LR47KT?

A: Yes. Both parts are identical in inductance (470 nH), tolerance (±10%), current rating (50 mA), DC resistance (420 mOhm maximum), shielding configuration, package type (0402 / 1005 Metric), and core material (ferrite). Mechanical and electrical compatibility is complete.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and operating temperature range. The MLF1005LR47KT is marked "Not For New Designs" and operates from -40°C to 85°C. The MLF1005GR47KT is an active product with an extended temperature range of -55°C to 125°C and a higher quality factor (Q = 30 versus Q = 25 at 10 MHz).

Q: Are there any package or footprint differences?

A: No. Both components use the identical 0402 (1005 Metric) surface mount package with dimensions of 1.00mm length × 0.50mm width and a maximum seated height of 0.55mm. PCB footprints are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MLF1005LR47KT and MLF1005GR47KT are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (unlimited moisture sensitivity). Regulatory compliance is equivalent.

Q: Which part should be selected for new designs?

A: The MLF1005GR47KT should be selected for new designs. It carries an active product status, ensuring long-term availability and manufacturing support. The extended operating temperature range and improved quality factor provide additional design margin.
