Substitute Part Grouping Explanation

Substitution of the MLZ2012A2R2MT000 is determined by the following critical parameters:

• Inductance Value: Must be 2.2 µH with ±20% tolerance
• Package / Case: Must be 0805 (2012 Metric) for mechanical and electrical compatibility
• Shielding Type: Must be shielded to maintain electromagnetic isolation
• Operating Temperature Range: Must support -55°C ~ 125°C minimum
• RoHS Compliance: Must maintain ROHS3 Compliant status
• Moisture Sensitivity Level: Must be MSL 1 or equivalent

The MLZ2012A2R2WT000 meets all substitution criteria. While it offers improved electrical performance characteristics (higher current rating and lower DCR), these enhancements do not compromise compatibility with applications designed for the MLZ2012A2R2MT000.

Engineering Selection Recommendations

The MLZ2012A2R2WT000 is the direct substitute for MLZ2012A2R2MT000 applications. Selection should be based on the following factors:

Product Status: The MLZ2012A2R2MT000 carries a Not For New Designs status, while the MLZ2012A2R2WT000 is Active. For new production and long-term supply continuity, the MLZ2012A2R2WT000 is the appropriate choice.

Compliance: Both parts maintain ROHS3 Compliant and REACH Unaffected status, ensuring regulatory alignment across applications.

Electrical Performance: The MLZ2012A2R2WT000 provides superior electrical characteristics with 650 mA current rating versus 160 mA, and reduced DC resistance of 150 mOhm versus 260 mOhm. These improvements enhance thermal performance and reduce power dissipation in the inductor.

Mechanical Compatibility: Identical package dimensions, height, and mounting type ensure direct PCB-level compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can MLZ2012A2R2WT000 replace MLZ2012A2R2MT000 in existing designs?

A: Yes. Both parts share identical inductance value (2.2 µH), tolerance (±20%), package (0805 / 2012 Metric), shielding type, operating temperature range, and compliance certifications. The MLZ2012A2R2WT000 offers enhanced current handling and lower DC resistance, making it a direct functional substitute.

Q: What are the key differences between these parts?

A: The primary differences are current rating (160 mA vs. 650 mA), DC resistance (260 mOhm vs. 150 mOhm), saturation current (160 mA vs. 210 mA), self-resonant frequency (100 MHz vs. 120 MHz), and product status (Not For New Designs vs. Active). The MLZ2012A2R2WT000 is the newer, actively supported variant.

Q: Are there packaging differences?

A: The MLZ2012A2R2MT000 is supplied in Tape & Reel (TR) format, while the MLZ2012A2R2WT000 is available in Cut Tape (CT) & Digi-Reel® format. Both are 0805 (2012 Metric) surface mount packages with identical physical dimensions and mounting compatibility.

Q: Will substitution affect thermal performance?

A: The MLZ2012A2R2WT000 exhibits lower DC resistance (150 mOhm vs. 260 mOhm), resulting in reduced resistive heating at equivalent current levels. This represents an improvement in thermal characteristics.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both MLZ2012A2R2MT000 and MLZ2012A2R2WT000 are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and use.
