MLZ2012E100MT000 Equivalent & Substitute Parts

Part Overview

The MLZ2012E100MT000 is a 10 µH shielded multilayer inductor manufactured by TDK Corporation in 0805 (2012 Metric) surface mount package. This component is rated for 60 mA maximum current with 400 mOhm DC resistance and operates across -55°C to 125°C. The part carries a "Not For New Designs" status, indicating it has been superseded in TDK's product line. Identifying equivalent substitute parts is necessary for design continuity, inventory management, and ensuring long-term component availability for existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MLZ2012E100MT000 must satisfy the following criteria:

• Inductance value of 10 µH (±20% tolerance)
• 0805 (2012 Metric) surface mount package
• Shielded multilayer ferrite core construction
• Operating temperature range of -55°C to 125°C
• ROHS3 compliance and MSL 1 rating

The original part's 60 mA current rating and 400 mOhm DCR establish the baseline electrical performance. Substitute parts may exceed these specifications while maintaining compatibility with the same package footprint and inductance value. Two qualified substitutes are identified based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

MLZ2012M100WT000 (TDK Corporation) is the primary substitute for the MLZ2012E100MT000. Both components are from the same manufacturer's MLZ series, share identical inductance and package specifications, and maintain full compliance with ROHS3 and MSL 1 requirements. The MLZ2012M100WT000 offers superior current handling at 350 mA with only marginally higher DCR of 470 mOhm, making it suitable for applications requiring increased current capacity within the same footprint. This part carries Active product status, ensuring long-term availability.

LQM21FN100M80L (Murata Electronics) serves as an alternative substitute when cross-manufacturer compatibility is acceptable. This part meets all core electrical and mechanical requirements with 100 mA current rating and 390 mOhm maximum DCR. The LQM21FN100M80L provides a 15 MHz self-resonant frequency specification and maintains Active product status. Selection between the two substitutes depends on application current requirements and manufacturer preference.

Frequently Asked Questions (FAQ)

Q: Can MLZ2012M100WT000 directly replace MLZ2012E100MT000 in existing designs?

A: Yes. Both parts share identical inductance (10 µH), tolerance (±20%), package (0805), shielding, core material, and operating temperature range. The higher current rating of MLZ2012M100WT000 does not create compatibility issues for applications originally designed for 60 mA operation.

Q: What is the impact of DCR differences between the original and substitute parts?

A: The original part specifies 400 mOhm DCR. MLZ2012M100WT000 has 470 mOhm and LQM21FN100M80L has 390 mOhm maximum. These variations fall within typical inductor manufacturing tolerances and do not affect footprint compatibility or basic circuit function in standard filtering and impedance matching applications.

Q: Are there any compliance or certification differences between the three parts?

A: All three parts are ROHS3 compliant with MSL 1 rating. The primary difference is product status: MLZ2012E100MT000 is marked "Not For New Designs," while both substitutes carry Active status, indicating ongoing manufacturer support and availability.

Q: Which substitute should be selected for new designs?

A: For new designs, either MLZ2012M100WT000 or LQM21FN100M80L is appropriate based on current requirements. MLZ2012M100WT000 is recommended for applications requiring higher current capacity. LQM21FN100M80L is suitable when current requirements do not exceed 100 mA and cross-manufacturer sourcing is preferred.

Q: Is the 0805 (2012 Metric) package footprint identical across all three parts?

A: Yes. All three parts use the 0805 (2012 Metric) package with identical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and maximum seated height (0.057" / 1.45mm), ensuring direct PCB footprint compatibility.
