Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLF2012DR12MT is determined by the following critical parameters:

Electrical Parameters:

• Inductance value: 120 nH (tolerance variance acceptable within design margin)
• Current rating: minimum 300 mA
• DC resistance: maximum 200 mOhm
• Shielding type: Shielded configuration required
• Self resonant frequency: 360 MHz
• Q factor: 20 @ 25 MHz

Mechanical Parameters:

• Package format: 0805 (2012 Metric) surface mount
• Physical dimensions: 2.00 mm L × 1.25 mm W × 1.05 mm H (max seated height)
• Mounting type: Surface mount

Compliance Parameters:

• RoHS3 compliance required
• REACH unaffected status
• Moisture sensitivity level: 1 (Unlimited)

The MLF2012DR12KT000 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters, with the distinction of active product status and improved inductance tolerance (±10% versus ±20%).

Parameter Comparison

Engineering Selection Recommendations

The MLF2012DR12KT000 is the qualified substitute for MLF2012DR12MT based on the following factors:

Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental standards.

Product Status Advantage: The MLF2012DR12KT000 carries active product status, providing assurance of continued manufacturing availability and supply chain stability, whereas the MLF2012DR12MT is designated "Not For New Designs."

Electrical Equivalence: All critical electrical parameters are identical, including inductance value, current rating, DC resistance, shielding configuration, and frequency characteristics. The improved inductance tolerance of ±10% in the substitute part provides tighter specification control compared to the ±20% tolerance of the original part.

Mechanical Compatibility: Identical package format, physical dimensions, and surface mount configuration ensure direct board-level compatibility without layout or assembly modifications.

Frequently Asked Questions (FAQ)

Q: Can MLF2012DR12KT000 be used as a direct replacement for MLF2012DR12MT?

A: Yes. Both parts share identical inductance values, current ratings, DC resistance specifications, shielding types, and package formats. The substitute part meets or exceeds all electrical and mechanical requirements of the original part.

Q: What is the significance of the inductance tolerance difference?

A: The MLF2012DR12MT specifies ±20% tolerance, while MLF2012DR12KT000 specifies ±10% tolerance. The tighter tolerance of the substitute part provides improved consistency in inductance values across production batches, which may benefit applications with stringent frequency response or impedance matching requirements.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels. Regulatory and environmental compliance requirements are equivalent.

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

A: This designation indicates that TDK Corporation has transitioned the MLF2012DR12MT to end-of-life status. The MLF2012DR12KT000 represents the active product line continuation for this inductance value and package format.

Q: Will the substitute part fit the same PCB footprint?

A: Yes. Both parts use the 0805 (2012 Metric) package with identical physical dimensions (2.00 mm × 1.25 mm × 1.05 mm max height). No PCB layout modifications are required.

Q: Are there any performance differences in high-frequency applications?

A: No. Both parts exhibit identical Q factors (20 @ 25 MHz) and self-resonant frequencies (360 MHz), ensuring equivalent performance across the specified frequency range.
