Procurement Notes

Verify the specific suffix '-3' against the manufacturer's current datasheet to confirm if it denotes a distinct variant or packaging specification compared to standard models. Ensure compatibility with the target PCB footprint and thermal requirements before finalizing procurement orders.

Selection Notes

Select this component when a compact 45mm diameter speaker is required for general audio output. The 8-ohm impedance suits standard driver circuits, while the 1W rating provides adequate volume for close-proximity applications. Consider the 450Hz lower frequency limit for bass response requirements.

Part Context

This model belongs to the PUI Audio speaker series, designed for reliable acoustic performance in various electronic devices. The AS04508MR-3-R represents a standard electromagnetic solution suitable for mass production environments requiring consistent audio quality and mechanical stability.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate other PUI Audio speakers with matching 8-ohm impedance and similar physical dimensions for potential cross-referencing.
