Substitute Part Grouping Explanation

Substitution of the GLCR2012T2R2M-HC is determined by strict equivalence across the following critical parameters:

• Inductance Value: 2.2 µH with ±20% tolerance
• Current Rating: 600 mA minimum
• Package / Case: 0805 (2012 Metric) surface mount
• Shielding: Shielded construction required
• Physical Dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)

The MLZ2012M2R2HT000 qualifies as a direct substitute based on matching inductance, current rating, package specification, and shielding requirement. While the substitute exhibits improved DC resistance (160mOhm versus 200mOhm) and higher saturation current (400mA versus 375mA), these represent performance enhancements within acceptable substitution parameters.

Frequently Asked Questions (FAQ)

Q: Can the MLZ2012M2R2HT000 be used as a direct replacement for the GLCR2012T2R2M-HC?

A: Yes. Both components share identical inductance values (2.2 µH), current ratings (600 mA), package specifications (0805 / 2012 Metric), and shielding configuration. The substitute is electrically and mechanically compatible for direct substitution.

Q: What is the difference in DC resistance between these components?

A: The GLCR2012T2R2M-HC has a DC resistance of 200mOhm, while the MLZ2012M2R2HT000 has 160mOhm. The lower resistance in the substitute reduces power dissipation and heat generation in the inductor.

Q: Are there any height differences that affect PCB assembly?

A: Yes. The GLCR2012T2R2M-HC has a maximum seated height of 0.053" (1.35mm), while the MLZ2012M2R2HT000 is 0.041" (1.05mm). The substitute is lower profile, which may provide additional clearance in space-constrained designs.

Q: Does the substitute meet current environmental regulations?

A: Yes. The MLZ2012M2R2HT000 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the saturation current difference?

A: The GLCR2012T2R2M-HC has a saturation current of 375mA, while the MLZ2012M2R2HT000 is rated at 400mA. The higher saturation current in the substitute provides additional margin before inductor saturation occurs.

Q: Are the operating temperature ranges different?

A: Yes. The GLCR2012T2R2M-HC operates from -40°C to 105°C, while the MLZ2012M2R2HT000 operates from -55°C to 125°C. The substitute provides a wider operating temperature range.
