Substitute Part Grouping Explanation

Substitution of the GLCR2012T220M-HC is determined by the following critical parameters:

• Inductance Value: 22 µH (±20% tolerance acceptable)
• Package / Case: 0805 (2012 Metric) for PCB footprint compatibility
• Mounting Type: Surface Mount
• Shielding: Shielded configuration
• Current Rating: Minimum 220 mA continuous current capability
• DC Resistance: Maximum 2 Ohm (acceptable increase from 1 Ohm original specification)
• Operating Temperature Range: Minimum -40°C ~ 105°C coverage

The MLZ2012M220WT000 qualifies as a direct substitute based on matching inductance value, package dimensions, shielding requirement, and surface mount configuration. The substitute maintains functional equivalence within the specified tolerance band while offering active product status and extended temperature range capability.

Engineering Selection Recommendations

The MLZ2012M220WT000 is the designated substitute for the obsolete GLCR2012T220M-HC based on the following engineering criteria:

Product Status: The substitute is classified as Active, ensuring continued availability and manufacturing support from TDK Corporation, whereas the original part is Obsolete.

Compliance & Certifications: The MLZ2012M220WT000 carries ROHS3 compliance certification, meeting current regulatory requirements for electronic component manufacturing and distribution.

Functional Equivalence: Both components share identical inductance value (22 µH), inductance tolerance (±20%), package configuration (0805 / 2012 Metric), and shielding specification. The substitute maintains surface mount compatibility with identical footprint dimensions.

Electrical Performance: The substitute operates within acceptable parameter variance. The continuous current rating of 220 mA represents a 12% reduction from the original 250 mA specification. The DC resistance increase from 1 Ohm to 2 Ohm and saturation current reduction from 105 mA to 60 mA require circuit-level evaluation to confirm suitability for the specific application.

Environmental Capability: The substitute provides extended operating temperature range (-55°C ~ 125°C) compared to the original (-40°C ~ 105°C), offering improved thermal performance margin.

Frequently Asked Questions (FAQ)

Q: Can the MLZ2012M220WT000 be used as a direct drop-in replacement for the GLCR2012T220M-HC?

A: The MLZ2012M220WT000 is mechanically and electrically compatible for PCB assembly. Both components use identical 0805 (2012 Metric) package dimensions and footprints. However, the 12% reduction in continuous current rating (220 mA vs. 250 mA) and doubled DC resistance (2 Ohm vs. 1 Ohm) require circuit validation to confirm functional equivalence in the specific application.

Q: What is the difference between wirewound and multilayer inductor construction?

A: The original GLCR2012T220M-HC uses wirewound construction, while the substitute MLZ2012M220WT000 uses multilayer ferrite construction. Both are shielded configurations suitable for the 0805 package. Construction differences may affect frequency response characteristics and EMI performance, which should be evaluated based on application requirements.

Q: Are there any height clearance concerns when substituting these parts?

A: The substitute has a maximum seated height of 0.057" (1.45mm) compared to the original 0.053" (1.35mm), representing a 0.004" (0.10mm) increase. This minimal difference is unlikely to cause clearance issues in standard PCB designs but should be verified against specific board layout constraints.

Q: Does the substitute meet current environmental and compliance standards?

A: Yes. The MLZ2012M220WT000 is ROHS3 compliant and carries REACH Unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution in regulated markets.

Q: What is the inventory status for the substitute part?

A: The MLZ2012M220WT000 has 5720 pieces in stock as new original inventory, available in Cut Tape (CT) and Digi-Reel® packaging options, ensuring supply continuity for production requirements.
