Procurement Notes

Verify the specific datasheet version for the AS04004MS to confirm RoHS compliance status and exact dimensional tolerances. Ensure that the selected surface mount footprint matches the manufacturer's recommended land pattern. Confirm operating temperature ranges align with the intended application environment before finalizing procurement specifications.

Selection Notes

Select this component when a compact, board-mountable speaker is required for low-to-mid volume applications. The 4-ohm impedance suits standard amplifier outputs. Consider the square frame dimensions for enclosure space constraints. Verify that the 115 Hz lower frequency limit meets the bass response requirements of the target system.

Part Context

This model belongs to the AS series of full-range point-source speakers from PUI Audio. The series focuses on providing reliable audio transducers for various electronic devices. The AS04004MS represents a specific configuration within this lineup, optimized for surface mount assembly processes and general-purpose audio reproduction tasks.

Replacement Considerations

Cross-reference with other PUI Audio models in the AS series for similar impedance and power ratings. Verify mechanical compatibility if substituting with different frame shapes. Ensure electrical parameters match the driving circuit requirements before implementing any alternative part numbers.
