• Portable electronic equipment requiring small form factor speakers

Speakers Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer documentation may evolve. Confirm that the solder pad termination style matches your PCB layout requirements. Ensure the operating temperature range aligns with your final product environment. Cross-reference the part number with official Same Sky channels to avoid counterfeit components.

Speakers Selection Notes

Select this component when a low-profile, round speaker is required for general audio tasks. The 4-ohm impedance suits standard amplifier outputs. Consider the 3-watt power rating against your system's maximum output levels. The 22 mm diameter fits standard mounting holes for similar miniature transducers.

Speakers Part Context

This model belongs to the Same Sky miniature speaker series, designed for integration into compact electronic assemblies. It replaces older CUI Devices offerings under the same Sky branding. The series focuses on balancing acoustic performance with minimal physical footprint for modern portable devices.

Speakers Replacement Considerations

Direct substitutes within the Same Sky lineup should be verified via official cross-reference tools. Generic replacements must match the 4-ohm impedance and 22 mm diameter constraints. Ensure replacement units support the required 3-watt power handling capability.
