Engineering Selection Recommendations

The MLF2012C180KT000 is the direct substitute for the MLF2012C180MT. Both components are manufactured by TDK Corporation within the MLF series and maintain identical electrical and mechanical specifications for inductance, current rating, DC resistance, package dimensions, and frequency characteristics.

The MLF2012C180KT000 offers advantages in production continuity: it carries Active product status compared to the Not For New Designs designation of the original part, ensuring long-term availability and supply chain stability. The substitute features tighter inductance tolerance (±10% versus ±20%), which may provide improved circuit performance in applications requiring closer value matching.

The operating temperature range of the substitute (-40°C to 85°C) is narrower than the original part (-55°C to 125°C). Applications requiring operation below -40°C or above 85°C must retain the MLF2012C180MT or identify alternative solutions. For standard industrial and commercial temperature ranges, the substitute is fully compatible.

Both components maintain identical RoHS3 compliance, moisture sensitivity level, and regulatory certifications (REACH Unaffected, ECCN EAR99, HTSUS 8504.50.8000).

Frequently Asked Questions (FAQ)

Q: Can MLF2012C180KT000 be used as a direct replacement for MLF2012C180MT in existing designs?

A: Yes, for applications operating within the -40°C to 85°C temperature range. The substitute maintains identical inductance, current rating, DC resistance, package dimensions, and frequency characteristics. If your application requires operation below -40°C or above 85°C, the original part must be retained.

Q: What is the difference in inductance tolerance between these parts?

A: The MLF2012C180MT has ±20% tolerance, while the MLF2012C180KT000 has ±10% tolerance. The substitute provides tighter tolerance control, which may improve circuit performance in applications sensitive to inductance variation.

Q: Are the physical dimensions and mounting characteristics identical?

A: Yes. Both parts use the 0805 (2012 Metric) surface mount package with identical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and maximum seated height (0.057" / 1.45mm). They are mechanically interchangeable on PCBs designed for either part.

Q: What is the significance of the product status change from "Not For New Designs" to "Active"?

A: The Active status of MLF2012C180KT000 indicates ongoing manufacturing and long-term availability from TDK Corporation. The Not For New Designs status of the original part signals end-of-life or transition phase, making the substitute the recommended choice for production continuity and future supply assurance.

Q: Are compliance certifications maintained in the substitute part?

A: Yes. Both parts are ROHS3 compliant, REACH Unaffected, and carry identical regulatory classifications (ECCN EAR99, HTSUS 8504.50.8000). Moisture sensitivity level remains at MSL 1 (Unlimited) for both components.
