Frequently Asked Questions (FAQ)

Q: Can MLF2012A1R5KTD25 be used as a direct replacement for MLF2012A1R5MT?

A: Yes. Both inductors share identical inductance values, current ratings, DC resistance specifications, package dimensions, and operating temperature ranges. No circuit modifications are required.

Q: What is the difference between the ±20% and ±10% inductance tolerances?

A: The MLF2012A1R5MT has ±20% tolerance, while MLF2012A1R5KTD25 has ±10% tolerance. The substitute provides tighter inductance accuracy, which may improve circuit performance in applications sensitive to inductance variation.

Q: Does the AEC-Q200 rating on MLF2012A1R5KTD25 affect compatibility?

A: No. AEC-Q200 certification indicates the part meets automotive reliability standards and undergoes additional qualification testing. This does not affect electrical or mechanical compatibility with the original part.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both MLF2012A1R5MT and MLF2012A1R5KTD25 are packaged in 0805 (2012 Metric) with identical length, width, and maximum seated height specifications. PCB footprints and assembly processes remain unchanged.

Q: What is the significance of the "Not For New Designs" status on MLF2012A1R5MT?

A: This designation indicates TDK Corporation is discontinuing the MLF2012A1R5MT for new product development. The MLF2012A1R5KTD25 is the recommended active alternative for all new and ongoing applications.

Q: Are moisture sensitivity levels the same for both parts?

A: Yes. Both inductors carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
