Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPI4040R1-1R0-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 1 µH (exact match required)
• Tolerance: ±20% (standard specification)
• Shielding: Shielded configuration
• Operating temperature range: -55°C to 125°C minimum
• Mounting type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Factors:

• Current rating: Substitute must equal or exceed 3.7 A
• DC resistance: Substitute should be comparable or lower
• Package dimensions: Physical compatibility with PCB layout

The substitute parts listed below meet the primary matching criteria and provide equivalent or improved electrical performance characteristics.
