Key Parameters

Substitute Part Grouping Explanation

Substitution of the MLF1005A2R2KT is determined by strict equivalence across the following critical parameters:

• Inductance value: 2.2 µH with ±10% tolerance
• Current rating: 10 mA minimum
• Package: 0402 (1005 Metric) surface mount
• Shielding: Shielded construction required
• Core material: Ferrite
• DC resistance: Maximum 1.8Ohm (or lower)
• Compliance: ROHS3 compliant

The AIML-0402-2R2K-T from Abracon LLC meets all substitution criteria. Both components share identical inductance, tolerance, current rating, package dimensions, and core material specifications. The substitute part demonstrates equivalent or superior electrical performance with a maximum DC resistance of 1.75Ohm, which is lower than the original specification.

Parameter Comparison

Engineering Selection Recommendations

The AIML-0402-2R2K-T is a direct functional equivalent to the MLF1005A2R2KT. Selection of the Abracon substitute is supported by the following factors:

• Both components maintain identical inductance and tolerance specifications
• The substitute exhibits lower DC resistance (1.75Ohm vs. 1.8Ohm maximum), providing improved electrical performance
• The substitute part is currently in active production status, ensuring long-term availability
• Both components carry ROHS3 compliance and MSL Level 1 ratings
• The substitute operates across an extended temperature range (-55°C to 125°C), encompassing the original operating window
• Mechanical compatibility is confirmed through identical package dimensions and surface mount configuration
• The substitute height of 0.026" (0.65mm) represents a minimal increase from the original 0.022" (0.55mm) and remains within typical PCB assembly tolerances

Frequently Asked Questions (FAQ)

Q: Can the AIML-0402-2R2K-T be used as a direct replacement for the MLF1005A2R2KT?

A: Yes. Both components share identical inductance (2.2 µH), tolerance (±10%), current rating (10 mA), package (0402), and core material (ferrite). The substitute meets or exceeds all electrical specifications of the original part.

Q: What is the significance of the DC resistance difference between the two parts?

A: The AIML-0402-2R2K-T has a maximum DC resistance of 1.75Ohm compared to the MLF1005A2R2KT at 1.8Ohm maximum. Lower DC resistance reduces power dissipation and heat generation in the circuit, representing an improvement over the original specification.

Q: Are there any height compatibility concerns with the substitute part?

A: The substitute part has a maximum seated height of 0.026" (0.65mm) versus the original 0.022" (0.55mm). This 0.004" (0.10mm) difference is negligible for standard PCB assembly processes and does not affect component placement or board-level compatibility.

Q: Does the extended operating temperature range of the substitute affect compatibility?

A: No. The AIML-0402-2R2K-T operates from -55°C to 125°C, which fully encompasses the original operating range of -40°C to 85°C. The extended range provides additional design margin without introducing compatibility issues.

Q: Are both parts RoHS compliant?

A: Yes. Both the MLF1005A2R2KT and AIML-0402-2R2K-T are ROHS3 compliant with MSL Level 1 (unlimited moisture sensitivity), meeting current environmental and regulatory requirements.

Q: What is the packaging difference between the two parts?

A: The MLF1005A2R2KT is supplied in standard packaging, while the AIML-0402-2R2K-T is supplied in Tape & Reel (TR) format. Both are compatible with automated assembly equipment and standard component handling procedures.
