Speakers Procurement Notes

Verify the specific suffix (I04) against official Knowles documentation to ensure correct impedance and acoustic characteristics. Confirm RoHS compliance status through current datasheets. Check for end-of-life notifications or discontinuance alerts prior to finalizing procurement plans to avoid supply chain disruptions.

Speakers Selection Notes

Select this component when a high-efficiency, low-power balanced armature receiver is required. The 128 Ohm impedance matches specific driver circuits. Ensure the 4 kHz upper frequency limit meets application bandwidth needs. Verify physical clearance for the 6.3 x 4.29 mm footprint and top-port orientation during PCB layout.

Speakers Part Context

This model belongs to the Knowles FED series of balanced armature receivers. These components are engineered for precision audio applications requiring small size and reliable performance. The series typically offers various impedance and sensitivity options to suit different electronic designs.

Speakers Replacement Considerations

Cross-reference with other Knowles models in the ED/FED series for mechanical compatibility. Verify that substitute parts match the 128 Ohm impedance and 102.5 dBA SPL requirements. Ensure the replacement maintains the same package dimensions and solder pad configuration.
