Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPH2611LR5F is determined by alignment across the following critical parameters:

• Manufacturer consistency (Knowles product line)
• Microphone type and technology (MEMS silicon-based)
• Moisture sensitivity classification (MSL 1)
• Export compliance codes (ECCN and HTSUS alignment)
• Regulatory compliance status (RoHS compliance)

The SPH6611LR5H-1 qualifies as a manufacturer-recommended substitute based on these criteria. Both components share identical MSL ratings, export classifications, and RoHS compliance status, ensuring regulatory and environmental compatibility.

Parameter Comparison
