Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLF1005L2R2KT is determined by the following critical parameters:

• Inductance Value: Must be 2.2 µH with ±10% tolerance to maintain circuit performance
• Package Footprint: Must be 0402 (1005 Metric) for PCB compatibility
• Shielding Type: Must be shielded to match electromagnetic containment requirements
• Current Rating: Must support the application's maximum current demand
• DC Resistance: Lower or equal DCR values are acceptable; higher values may impact circuit efficiency
• Compliance: Must maintain ROHS3 compliance for regulatory alignment

The AIML-0402-2R2K-T from Abracon LLC meets the core electrical and mechanical substitution criteria, sharing identical inductance, tolerance, package, and shielding specifications.

Parameter Comparison

Engineering Selection Recommendations

The AIML-0402-2R2K-T is an active product from Abracon LLC and represents a viable substitute for the MLF1005L2R2KT in applications where the following conditions are met:

• Circuit current demand does not exceed 10 mA (the limiting factor for this substitute)
• DC resistance increase from 1.15Ohm to 1.75Ohm is acceptable for the application
• Self-resonant frequency of 28MHz is sufficient for the operating frequency range
• Extended operating temperature range (-55°C ~ 125°C) provides additional thermal margin
• PCB layout accommodates the increased seated height of 0.026" (0.65mm) versus 0.022" (0.55mm)

Both components maintain ROHS3 compliance and identical package footprints, ensuring regulatory and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the AIML-0402-2R2K-T directly replace the MLF1005L2R2KT in all applications?

A: Direct replacement is possible only if the application current requirement does not exceed 10 mA. The MLF1005L2R2KT supports 15 mA, while the AIML-0402-2R2K-T is rated for 10 mA maximum. Exceeding this rating will cause saturation and performance degradation.

Q: What is the impact of the higher DC resistance in the substitute part?

A: The AIML-0402-2R2K-T has 1.75Ohm maximum DCR compared to 1.15Ohm for the MLF1005L2R2KT. This 0.6Ohm increase will result in higher power dissipation and heat generation at rated current. Circuit thermal analysis is required to confirm acceptability.

Q: Are the package dimensions compatible?

A: Both parts use the 0402 (1005 Metric) package with identical length (0.039") and width (0.020"). The seated height differs by 0.004" (0.11mm), with the substitute being slightly taller. PCB clearance must be verified for space-constrained applications.

Q: Why is the self-resonant frequency lower for the substitute?

A: The AIML-0402-2R2K-T has a self-resonant frequency of 28MHz versus 80MHz for the MLF1005L2R2KT. This affects high-frequency performance. Applications operating above 28MHz may experience impedance changes and reduced inductor effectiveness.

Q: Are both parts RoHS compliant?

A: Yes, both the MLF1005L2R2KT and AIML-0402-2R2K-T are ROHS3 compliant, meeting regulatory requirements for restricted substance elimination.

Q: What is the significance of the product status difference?

A: The MLF1005L2R2KT is marked "Not For New Designs," indicating TDK has discontinued active development and support. The AIML-0402-2R2K-T is marked "Active," ensuring ongoing availability, technical support, and supply chain stability for new and existing designs.
