Substitute Part Grouping Explanation

Substitution of the GLFR2012T2R2M-LR is determined by the following critical parameters:

• Inductance Value: 2.2 µH with ±20% tolerance
• Package Compatibility: 0805 (2012 Metric) surface mount form factor
• Shielding Type: Shielded construction
• Physical Dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Electrical Characteristics: DC resistance, current rating, and saturation current performance

The MLZ2012M2R2HT000 qualifies as a substitute based on matching inductance value, package dimensions, shielding configuration, and surface mount compatibility. While the substitute exhibits different current ratings and DC resistance specifications, these variations remain within acceptable parameters for equivalent functional performance in the 0805 shielded inductor category.

Engineering Selection Recommendations

The MLZ2012M2R2HT000 is the designated substitute for the obsolete GLFR2012T2R2M-LR. Selection of this alternative is supported by the following factors:

• Product Status: The MLZ2012M2R2HT000 maintains active production status, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: Both components share identical REACH and ECCN classifications, maintaining compliance requirements across applications.
• Package Compatibility: Identical 0805 (2012 Metric) package dimensions enable direct PCB layout compatibility without redesign.
• Inductance Specification: Both components deliver 2.2 µH inductance with ±20% tolerance, meeting circuit design requirements.
• Thermal Performance: The substitute offers an extended operating temperature range (-55°C ~ 125°C) compared to the original part, providing enhanced thermal margin.

The substitute exhibits reduced current rating (600 mA versus 900 mA) and increased DC resistance (160 mOhm versus 88 mOhm). Circuit designs must evaluate whether these electrical characteristic differences are compatible with application requirements.

Frequently Asked Questions (FAQ)

Q: Can the MLZ2012M2R2HT000 be used as a direct replacement for the GLFR2012T2R2M-LR?

A: The MLZ2012M2R2HT000 is mechanically and electrically compatible for applications where the reduced current rating (600 mA) and increased DC resistance (160 mOhm) do not exceed circuit design limits. Both components share identical inductance values, package dimensions, and shielding configuration.

Q: What are the key differences between these two inductors?

A: The primary differences are current rating (900 mA versus 600 mA), DC resistance (88 mOhm versus 160 mOhm), saturation current (240 mA versus 400 mA), and product status (obsolete versus active). The substitute offers a wider operating temperature range and lower maximum seated height.

Q: Are there any PCB layout considerations when switching to the MLZ2012M2R2HT000?

A: Both components use the 0805 (2012 Metric) package with identical length and width dimensions (0.079" x 0.049"). The substitute has a lower maximum seated height (0.041" versus 0.053"), which may provide additional clearance in space-constrained designs.

Q: What compliance certifications apply to the substitute part?

A: The MLZ2012M2R2HT000 is ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both components share identical REACH and ECCN classifications.

Q: How do the electrical characteristics affect circuit performance?

A: The increased DC resistance of the substitute (160 mOhm versus 88 mOhm) results in higher power dissipation at equivalent current levels. Applications operating near the 900 mA rating of the original part must confirm that the 600 mA rating of the substitute is sufficient for circuit requirements.
