Speakers Procurement Notes

Verify the specific revision code and packaging configuration directly with the manufacturer or authorized distributors before ordering. Ensure that the mechanical footprint matches the target PCB design, as minor dimensional variations can occur between production batches. Confirm active status and availability through official channels to avoid counterfeit components.

Speakers Selection Notes

Select this component when a small form factor balanced armature speaker is required. The 225 Ohm impedance suits specific driver circuits. The 104 dBA sensitivity indicates high output capability for its size. Consider the top port orientation for acoustic integration in tight enclosures compared to bottom-port alternatives.

Speakers Part Context

This part belongs to Knowles' line of miniature balanced armature receivers. These components are engineered for portable electronics where size and weight are critical constraints. The FC series typically offers consistent performance across varying environmental conditions, supporting reliable audio reproduction in handheld devices.

Speakers Replacement Considerations

Check datasheets for compatible substitutes with matching impedance (225 Ohms) and similar dimensions. Verify acoustic performance curves and mounting compatibility before substitution.
