Substitute Part Grouping Explanation

Substitution eligibility for the MLF1005LR56KT is determined by strict equivalence across the following critical parameters:

• Inductance value: 560 nH with ±10% tolerance
• Current rating: 45 mA minimum
• DC resistance: 470 mOhm maximum
• Package: 0402 (1005 Metric) surface mount
• Shielding: Shielded construction
• Core material: Ferrite
• Compliance: ROHS3 and REACH requirements

The MLF1005GR56KT meets all substitution criteria. This part maintains identical electrical specifications for inductance, current rating, and DC resistance, uses the same package and shielding configuration, and satisfies all regulatory compliance requirements. The primary distinction is product status: MLF1005GR56KT is Active, whereas MLF1005LR56KT is Not For New Designs.
