Key Parameters

Substitute Part Grouping Explanation

The MLZ2012M1R0HT000 qualifies as a functional equivalent based on the following critical parameters:

Matching Parameters:

• Inductance: 1 µH (identical)
• Inductance Tolerance: ±20% (identical)
• Package / Case: 0805 (2012 Metric) (identical)
• Shielding: Shielded (identical)
• Mounting Type: Surface Mount (identical)

Differing Parameters:

• Current Rating: 800 mA (substitute) vs. 1.15 A (main part)
• DC Resistance: 100mOhm (substitute) vs. 58mOhm (main part)
• Operating Temperature Range: -55°C ~ 125°C (substitute) vs. -40°C ~ 105°C (main part)
• Product Status: Active (substitute) vs. Obsolete (main part)

The MLZ2012M1R0HT000 maintains identical inductance, tolerance, package, and shielding characteristics. The substitute exhibits lower current rating and higher DC resistance, requiring circuit-level validation to confirm suitability for the intended application.

Parameter Comparison

Engineering Selection Recommendations

The MLZ2012M1R0HT000 is an active product with ROHS3 compliance, providing regulatory advantage over the obsolete GLFR2012T1R0M-LR. Both components maintain REACH Unaffected status and identical moisture sensitivity classification.

Selection of the MLZ2012M1R0HT000 requires confirmation that the application circuit tolerates the reduced current rating of 800 mA and increased DC resistance of 100mOhm. The substitute's extended operating temperature range (-55°C ~ 125°C) provides broader environmental coverage compared to the main part (-40°C ~ 105°C).

Frequently Asked Questions (FAQ)

Q: Can MLZ2012M1R0HT000 directly replace GLFR2012T1R0M-LR in all applications?

A: Direct replacement is possible only if the circuit design accommodates the lower current rating (800 mA vs. 1.15 A) and higher DC resistance (100mOhm vs. 58mOhm). Circuit-level analysis is required to confirm compatibility.

Q: Are the physical dimensions compatible for PCB layout?

A: Both components use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W). The substitute has a maximum seated height of 0.057" compared to 0.053" for the main part, a 0.004" difference that typically does not affect PCB assembly.

Q: What is the significance of the product status difference?

A: The GLFR2012T1R0M-LR is obsolete, indicating discontinued manufacturing and limited future availability. The MLZ2012M1R0HT000 is active, ensuring ongoing supply and manufacturing support.

Q: How do the saturation current specifications compare?

A: The MLZ2012M1R0HT000 exhibits higher saturation current (700mA) compared to the GLFR2012T1R0M-LR (300mA), indicating greater tolerance to transient current spikes before inductance degradation occurs.

Q: Are there compliance or certification differences?

A: The MLZ2012M1R0HT000 carries ROHS3 compliance certification, while the obsolete GLFR2012T1R0M-LR does not specify this status. Both maintain REACH Unaffected classification.
