Speakers Procurement Notes

Verify current availability status as the component is listed as obsolete. Confirm that the specific acoustic requirements, including impedance and frequency response, align with the design specifications before finalizing procurement decisions for legacy systems.

Speakers Selection Notes

Select this component when a high-sensitivity, low-power balanced armature receiver is required. Ensure the application supports the specific 152 Ohm impedance and top-port orientation. Consider the discontinued status for long-term supply chain planning.

Speakers Part Context

This part belongs to the EC series of speakers from Knowles. It is designed for applications requiring precise audio reproduction in small form factors. The balanced armature design offers efficiency advantages over dynamic drivers in similar size constraints.

Speakers Replacement Considerations

No public confirmed substitute part numbers are available. Due to the obsolete status, alternative components must be evaluated based on matching electrical and mechanical specifications.
