Substitute Part Grouping Explanation

Substitution eligibility for the MLZ2012A1R0MT000 is determined by strict equivalence across the following critical parameters:

• Inductance Value: 1 µH (exact match required)
• Current Rating: 900 mA (exact match required)
• DC Resistance: 100 mOhm (exact match required)
• Saturation Current: 280 mA (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Shielding Type: Shielded (exact match required)
• Core Material: Ferrite (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Compliance Standards: ROHS3 Compliant, Moisture Sensitivity Level 1

The MLZ2012A1R0WT000 meets all substitution criteria as a direct equivalent part. The primary distinction between the main part and its substitute is the packaging format: the MLZ2012A1R0MT000 is supplied in Cut Tape (CT) & Digi-Reel® format, while the MLZ2012A1R0WT000 is supplied in Tape & Reel (TR) format. Both parts are manufactured by TDK Corporation within the MLZ series and maintain identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The MLZ2012A1R0WT000 is the direct substitute for the MLZ2012A1R0MT000. Both parts are manufactured by TDK Corporation and maintain identical electrical performance, mechanical dimensions, and compliance certifications. The MLZ2012A1R0WT000 carries Active product status, whereas the MLZ2012A1R0MT000 is designated "Not For New Designs," making the MLZ2012A1R0WT000 the preferred selection for ongoing production and new applications requiring this inductor specification.

The substitution is valid across all electrical parameters: 1 µH inductance, 900 mA current rating, 100 mOhm DC resistance, 280 mA saturation current, and 160 MHz self-resonant frequency. Both parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited) and operate within the -55°C to 125°C temperature range.

The only functional difference is the packaging format. The MLZ2012A1R0MT000 is supplied in Cut Tape (CT) & Digi-Reel® format, while the MLZ2012A1R0WT000 is supplied in standard Tape & Reel (TR) format. This distinction affects procurement and assembly processes but does not impact component performance or compatibility in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the MLZ2012A1R0WT000 be used as a direct replacement for the MLZ2012A1R0MT000?

A: Yes. The MLZ2012A1R0WT000 is a direct electrical and mechanical equivalent. All critical parameters—inductance, current rating, DC resistance, saturation current, package dimensions, and operating temperature range—are identical. The parts are interchangeable in circuit design and PCB layout.

Q: What is the difference between Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) packaging?

A: Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) are different packaging and delivery formats. Cut Tape format is typically used for smaller quantities and manual assembly, while Tape & Reel format is standard for automated pick-and-place assembly. The component itself is identical; only the packaging method differs.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the MLZ2012A1R0MT000 and MLZ2012A1R0WT000 are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: Why is the MLZ2012A1R0MT000 marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that TDK Corporation has superseded this part number in their product portfolio. The MLZ2012A1R0WT000 is the active equivalent and should be used for new applications and ongoing production.

Q: Do both parts have the same saturation current specification?

A: Yes. Both parts have a saturation current (Isat) of 280 mA, which is a critical parameter for inductor selection in current-limiting applications.

Q: What is the self-resonant frequency, and is it the same for both parts?

A: The self-resonant frequency is 160 MHz for both parts. This parameter defines the frequency at which the inductor's impedance reaches its maximum value and is important for high-frequency circuit design considerations.
