Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLF2012E120MT is determined by strict alignment across the following critical parameters:

• Inductance value: 12 µH (exact match required)
• Current rating: 15 mA minimum
• DC resistance: 900 mOhm maximum
• Package: 0805 (2012 Metric) surface mount
• Core material: Ferrite shielded construction
• Operating temperature range: -55°C to 125°C minimum
• Regulatory compliance: ROHS3 Compliant

The MLF2012E120KT000 satisfies all substitution criteria. Both parts share identical electrical specifications, physical dimensions, and environmental ratings. The primary distinction is inductance tolerance: the main part specifies ±20% tolerance, while the substitute offers tighter ±10% tolerance. This represents an improvement in precision without compromising functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Frequently Asked Questions (FAQ)

Q: Can MLF2012E120KT000 directly replace MLF2012E120MT in production?

A: Yes. Both parts share identical inductance (12 µH), current rating (15 mA), DC resistance (900 mOhm max), package (0805), and operating temperature range (-55°C to 125°C). The substitute offers improved tolerance specification without electrical or mechanical compromise.

Q: What is the significance of the tolerance difference between these parts?

A: The main part specifies ±20% inductance tolerance, while the substitute specifies ±10%. Tighter tolerance improves component value consistency across production batches. Applications sensitive to inductance variation may benefit from the substitute's enhanced precision.

Q: Are there any package or footprint differences?

A: No. Both parts use the 0805 (2012 Metric) surface mount package with identical dimensions (2.00mm L x 1.25mm W) and maximum seated height (1.45mm). PCB footprints and assembly processes remain unchanged.

Q: What is the product status difference, and does it affect compatibility?

A: The MLF2012E120MT is classified Not For New Designs, indicating TDK has discontinued active development. The MLF2012E120KT000 carries Active status, ensuring ongoing manufacturing and supply availability. This does not affect electrical or mechanical compatibility; it reflects supply chain longevity.

Q: Are both parts RoHS compliant?

A: Yes. Both MLF2012E120MT and MLF2012E120KT000 are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), meeting environmental and regulatory requirements for industrial and commercial applications.
