Speakers Procurement Notes

Verify the specific suffix code against the manufacturer's current datasheet to confirm exact dimensional tolerances and terminal configurations. Ensure the operating environment remains within the specified thermal limits to maintain acoustic integrity. Cross-reference the impedance rating with the driving circuit requirements to prevent overload conditions during procurement validation.

Speakers Selection Notes

Select this component when a compact 40 mm form factor is required for high-output applications. The 8-ohm impedance matches standard amplifier outputs commonly found in portable devices. Consider the 90 dBa sensitivity for environments requiring clear audibility without excessive power consumption. Verify that the 4.0 mm depth fits within the available chassis clearance constraints.

Speakers Part Context

This model belongs to the Same Sky CMS series of micro speakers, which are engineered for space-constrained electronic assemblies. The series emphasizes high efficiency and reliability through the use of rare-earth magnets. These components serve as primary audio transducers in various commercial and industrial equipment where size and weight are critical design parameters.

Speakers Replacement Considerations

Check for CMS-40504N-L152B or similar variants in the same series for potential mechanical compatibility. Confirm that substitute parts match the 8-ohm impedance and 500 mW power rating to ensure electrical equivalence. Verify that the replacement maintains the 40 mm diameter and 4.0 mm depth specifications.
