Speakers Procurement Notes

This component is currently listed as discontinued by the manufacturer. Availability is restricted, and Mouser indicates that the product is not sold in certain regions. Verification of current stock status and alternative sourcing channels is essential before integration into new production cycles due to the end-of-life status.

Speakers Selection Notes

Engineers should evaluate the 160 Ohm impedance and 6.3 kHz resonant frequency against circuit requirements. The 126 dBA sensitivity supports applications needing significant acoustic projection. Physical constraints must align with the 7.87 x 5.59 x 4.06 mm envelope. Solder pad termination dictates PCB layout specifications for reliable mounting.

Speakers Part Context

Belonging to the EF/FEF series, this receiver represents Knowles' portfolio of audio transducers. These components are engineered for precise acoustic performance within compact electronic assemblies. The series typically serves industries demanding reliable audio feedback or signaling mechanisms in portable and industrial electronics.

Speakers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, engineers must identify equivalent components based on matching electrical parameters (impedance, frequency) and mechanical dimensions.
