Key Parameters

Substitute Part Grouping Explanation

Substitution for the MLF2012DR39MT is determined by strict equivalence across the following critical parameters:

• Inductance Value: 390 nH (core functional specification)
• Package / Case: 0805 (2012 Metric) (mechanical and footprint compatibility)
• Current Rating: 200 mA (electrical performance requirement)
• DC Resistance: 450 mOhm maximum (thermal and efficiency constraint)
• Shielding: Shielded (electromagnetic performance requirement)
• Operating Temperature Range: -55°C to 125°C (environmental specification)

The substitute part MLF2012DR39KT000 meets all these criteria while offering improved product status (Active vs. Not For New Designs) and tighter inductance tolerance (±10% vs. ±20%).

Parameter Comparison

Engineering Selection Recommendations

The MLF2012DR39KT000 is the direct equivalent substitute for the MLF2012DR39MT. Both components are manufactured by TDK Corporation and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: MLF2012DR39KT000 carries Active status, whereas MLF2012DR39MT is designated Not For New Designs.

Both parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols. The tighter inductance tolerance of ±10% in the MLF2012DR39KT000 provides improved precision for applications requiring closer component matching, while the ±20% tolerance of the MLF2012DR39MT remains acceptable for general-purpose filtering and impedance matching circuits.

Frequently Asked Questions (FAQ)

Q: Can MLF2012DR39KT000 be used as a direct replacement for MLF2012DR39MT?

A: Yes. Both parts are identical in inductance value (390 nH), current rating (200 mA), DC resistance (450 mOhm maximum), package (0805 / 2012 Metric), and operating temperature range (-55°C to 125°C). They are electrically and mechanically interchangeable.

Q: What is the significance of the "Not For New Designs" status on MLF2012DR39MT?

A: This designation indicates the part is in mature or end-of-life phase. MLF2012DR39KT000, with Active status, is the recommended choice for new circuit designs and long-term production continuity.

Q: Does the inductance tolerance difference affect substitution?

A: The MLF2012DR39KT000 offers ±10% tolerance versus ±20% for MLF2012DR39MT. This tighter tolerance in the substitute part provides improved component consistency and is suitable for all applications where the original part was used.

Q: Are the packages identical?

A: Yes. Both parts use the 0805 (2012 Metric) surface mount package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and maximum seated height (0.041" / 1.05mm).

Q: Do both parts meet the same compliance standards?

A: Yes. Both MLF2012DR39MT and MLF2012DR39KT000 are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity rating.
