CDS-5709-254SP

Overview

The CDS-5709-254SP is a general-purpose round speaker manufactured by Same Sky. It features a 57 mm diameter frame with a 9 mm depth, utilizing a PET cone and neodymium magnet. The unit has a 4 Ohm impedance and a rated power of 2.5 W, with a maximum power handling of 3 W. The frequency response ranges from 450 Hz to 2.65 kHz, with a self-resonant frequency at approximately 400 Hz. Sensitivity is 85 dBA measured at 1W/1M. Termination is provided via solder tabs.

Feature Summary

• Round frame design with PET cone and neodymium magnet for efficient sound reproduction
• Top port configuration optimized for compact enclosure integration
• Solder tab termination style facilitates direct circuit board connection

Applications

• Consumer electronics audio output
• Medical device signaling
• Industrial control panel indicators

Procurement Notes

Verify the specific suffix 'SP' indicates solder tab termination, as variations may exist within the CDS series. Confirm RoHS3 compliance status for current production batches. Check lead times as standard delivery periods may vary by region. Ensure mechanical dimensions fit the target enclosure constraints before finalizing procurement.

Selection Notes

Select this component when a round form factor is required for acoustic applications. The 4 Ohm impedance matches common amplifier outputs. Consider the 9 mm depth constraint for tight spaces. Verify that the 450 Hz lower frequency limit meets the application's bass requirements. Compare against rectangular alternatives if space geometry differs.

Part Context

This part belongs to the CDS series of rectangular and round micro-speakers from Same Sky. The series offers various impedances and power ratings. The CDS-5709 variant specifically denotes the 57 mm diameter round model. It is designed for cost-effective audio solutions in portable and fixed devices.

Replacement Considerations

Direct substitutes include other 57 mm round speakers with similar 4 Ohm impedance and 2.5 W rating. Verify mounting hole patterns and terminal types match. Cross-reference with CUI Devices legacy part numbers if transitioning from older designs.
