GLCR2012T100M-HC Equivalent & Substitute Parts

Part Overview

The GLCR2012T100M-HC is a 10 µH shielded wirewound inductor manufactured by TDK Corporation, designed for surface mount applications in the 0805 (2012 Metric) package. This component is rated for 380 mA continuous current with a DC resistance of 500mOhm and operates across the temperature range of -40°C to 105°C. The part is currently listed as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design requirements and procurement needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GLCR2012T100M-HC is determined by the following critical parameters:

• Inductance Value: 10 µH (exact match required)
• Package / Case: 0805 (2012 Metric) (physical compatibility)
• Shielding: Shielded (electromagnetic performance requirement)
• Tolerance: ±20% (specification compliance)
• Mounting Type: Surface Mount (assembly compatibility)

The MLZ2012M100HT000 meets these core substitution criteria. While differences exist in current rating, DC resistance, and inductor type (multilayer vs. wirewound), the part maintains electrical and mechanical compatibility within the specified tolerance and performance envelope for this product category.

Parameter Comparison

Engineering Selection Recommendations

The MLZ2012M100HT000 is the designated substitute for the obsolete GLCR2012T100M-HC based on the following factors:

• Product Status: The MLZ2012M100HT000 maintains active production status, ensuring long-term availability and supply chain continuity.
• Compliance: The substitute part is ROHS3 compliant, meeting current regulatory requirements for electronic components.
• Electrical Compatibility: Both parts maintain identical inductance values (10 µH) and tolerance specifications (±20%), with matching shielding characteristics.
• Physical Compatibility: Identical package dimensions (0805 / 2012 Metric) and surface mount configuration enable direct PCB layout compatibility.
• Environmental Rating: The substitute part extends the operating temperature range (-55°C ~ 125°C) compared to the original part (-40°C ~ 105°C), providing broader application flexibility.

Design circuits operating at or below 300 mA continuous current can directly substitute the MLZ2012M100HT000 for the GLCR2012T100M-HC. Applications requiring the full 380 mA rating of the original part require circuit-level evaluation of the reduced current specification.

Frequently Asked Questions (FAQ)

Q: Can the MLZ2012M100HT000 be used as a direct replacement for the GLCR2012T100M-HC?

A: Yes, for applications operating at or below 300 mA continuous current. Both parts share identical inductance (10 µH), tolerance (±20%), package (0805 / 2012 Metric), and shielding specifications. The substitute part has a lower current rating (300 mA vs. 380 mA) and higher DC resistance (680mOhm vs. 500mOhm), which must be evaluated against circuit requirements.

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

A: The primary differences are: (1) inductor type—wirewound (GLCR2012T100M-HC) vs. multilayer (MLZ2012M100HT000); (2) current rating—380 mA vs. 300 mA; (3) DC resistance—500mOhm vs. 680mOhm; (4) saturation current—155mA vs. 200mA; (5) product status—obsolete vs. active; (6) operating temperature range—-40°C to 105°C vs. -55°C to 125°C.

Q: Are the physical dimensions compatible for PCB assembly?

A: Yes. Both parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). The seated height differs slightly (0.053" vs. 0.057"), which does not affect standard surface mount assembly processes.

Q: What is the impact of the higher DC resistance in the substitute part?

A: The MLZ2012M100HT000 has 680mOhm DC resistance compared to 500mOhm in the original part. This 36% increase in resistance results in higher power dissipation at equivalent current levels. Circuit designs must account for this additional resistive loss, particularly in power-sensitive applications.

Q: Is the reduced current rating a concern for my application?

A: The substitute part is rated for 300 mA continuous current versus 380 mA for the original. If your circuit operates below 300 mA, no design modification is required. If your circuit requires the full 380 mA rating, alternative components must be evaluated or circuit current levels must be reduced.

Q: Does the substitute part meet current regulatory requirements?

A: Yes. The MLZ2012M100HT000 is ROHS3 compliant and maintains REACH Unaffected status, meeting current environmental and regulatory standards for electronic components.
