• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Height: Must accommodate board layout constraints

Compliance Requirements:

• RoHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited)

The substitute part MLZ2012N2R2LT000 from TDK Corporation meets all critical electrical and mechanical parameters while offering improved DC resistance performance and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The MLZ2012N2R2LT000 from TDK Corporation is a direct functional substitute for the obsolete L0805C2R2MDMIT. Both components share identical inductance values, current ratings, tolerance specifications, and package dimensions. The substitute part offers superior DC resistance performance at 120mOhm compared to the 200mOhm maximum of the original part, resulting in lower power dissipation in circuit operation.

The TDK component maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. The extended operating temperature range of -55°C to 125°C provides broader environmental compatibility compared to the original -40°C to 85°C specification. The reduced seated height of 0.041" (1.05mm) versus 0.049" (1.25mm) accommodates tighter board layout requirements without functional impact.

Both components are surface mount devices in identical 0805 (2012 Metric) packages with ferrite shielded multilayer construction, ensuring direct PCB footprint compatibility and assembly process alignment.

Frequently Asked Questions (FAQ)

Q: Can the MLZ2012N2R2LT000 be used as a direct replacement for the L0805C2R2MDMIT?

A: Yes. Both components share the same inductance value (2.2 µH), current rating (800 mA), tolerance (±20%), package type (0805 / 2012 Metric), and shielding configuration. The substitute part meets or exceeds all electrical and mechanical requirements of the original component.

Q: What is the significance of the lower DC resistance in the substitute part?

A: The MLZ2012N2R2LT000 exhibits 120mOhm DC resistance compared to the 200mOhm maximum of the L0805C2R2MDMIT. Lower DC resistance reduces resistive losses and heat generation during operation, improving overall circuit efficiency without altering the inductance or current handling characteristics.

Q: Are there any physical compatibility concerns with the substitute part?

A: No. Both components use identical 0805 (2012 Metric) packages with matching length and width dimensions (0.079" x 0.049" / 2.00mm x 1.25mm). The substitute part has a slightly lower seated height (0.041" versus 0.049"), which presents no compatibility issues and may provide layout advantages in space-constrained applications.

Q: Does the substitute part maintain compliance certifications?

A: Yes. The MLZ2012N2R2LT000 is ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the original L0805C2R2MDMIT. Both components are REACH unaffected and classified under ECCN EAR99.

Q: What is the operational temperature difference between these components?

A: The L0805C2R2MDMIT operates from -40°C to 85°C, while the MLZ2012N2R2LT000 operates from -55°C to 125°C. The substitute part provides extended temperature range capability, supporting applications requiring broader environmental tolerance without performance degradation.

Q: Are there any frequency-related differences between these inductors?

A: The components are tested at different frequencies (1 MHz for the original, 2 MHz for the substitute). The substitute part specifies a self-resonant frequency of 120MHz. These differences do not affect substitution validity for standard DC and low-frequency AC applications within the specified current and inductance parameters.
