Substitute Part Grouping Explanation

Substitution of the MLF2012DR47MT is determined by strict equivalence across the following critical parameters:

• Inductance Value: 470 nH (core functional specification)
• Package / Case: 0805 (2012 Metric) (mechanical and footprint compatibility)
• Current Rating: 200 mA minimum (electrical performance requirement)
• DC Resistance: 500 mOhm maximum (thermal and efficiency constraint)
• Shielding: Shielded (electromagnetic interference control)
• Operating Temperature Range: -55°C to 125°C (environmental specification)

The MLF2012DR47KT000 meets all substitution criteria. While tolerance specifications differ between the main part (±20%) and the substitute (±10%), both parts maintain the same inductance value and all other critical electrical and mechanical parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MLF2012DR47KT000 is the direct equivalent substitute for the MLF2012DR47MT. Both parts are manufactured by TDK Corporation within the MLF series and maintain identical electrical performance specifications, mechanical dimensions, and environmental ratings. The substitute part carries an "Active" product status, whereas the original part is designated "Not For New Designs," making the MLF2012DR47KT000 the appropriate selection for new designs and ongoing production requirements.

Both parts satisfy ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The tighter inductance tolerance of the substitute part (±10% versus ±20%) provides improved precision without compromising any other electrical or mechanical characteristics.

Frequently Asked Questions (FAQ)

Q: Can MLF2012DR47KT000 be used as a direct replacement for MLF2012DR47MT in existing designs?

A: Yes. Both parts share identical inductance values (470 nH), current ratings (200 mA), DC resistance specifications (500 mOhm max), package dimensions (0805 / 2012 Metric), and operating temperature ranges (-55°C to 125°C). The substitute part is mechanically and electrically interchangeable.

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

A: The MLF2012DR47MT specifies ±20% tolerance, while the MLF2012DR47KT000 specifies ±10% tolerance. The tighter tolerance of the substitute part provides greater precision in inductance value without affecting compatibility or performance in applications designed for the original part.

Q: Are both parts suitable for high-frequency applications?

A: Both parts operate with a self-resonant frequency of 160 MHz and maintain a Q factor of 25 at 25 MHz, making them suitable for the same frequency range and high-frequency circuit applications.

Q: What is the significance of the "Not For New Designs" status on the MLF2012DR47MT?

A: This designation indicates that the MLF2012DR47MT is in mature or end-of-life status and should not be selected for new product designs. The MLF2012DR47KT000, with its "Active" status, is the recommended choice for new implementations.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited), ensuring equivalent regulatory and environmental compliance.
