CC31C165AN4P

Overview

The CC31C165AN4P is a general purpose round loudspeaker manufactured by Seltech. It features a 4-ohm impedance and a rated power of 3 watts, with a maximum power handling capacity of 4 watts. The device exhibits a sensitivity of 76 dB at 1W/1M. Its frequency range spans from 380 Hz to 7 kHz, with a self-resonant frequency (F0) of 380 Hz. The physical dimensions are approximately 31 mm in diameter and 16.5 mm to 21.5 mm in height, utilizing magnetic technology.

Feature Summary

• Round top port design for general acoustic applications
• Magnetic technology construction
• Integrated wires and connector configuration

Applications

• General purpose audio output devices
• Consumer electronics acoustic modules
• Industrial control panel indicators

Procurement Notes

Verify the specific datasheet version provided by Seltech or authorized distributors to confirm current manufacturing status and compliance certifications. Ensure that the operating environment remains within the specified temperature range of 5°C to 35°C and humidity levels of 45% to 85%. Confirm mechanical mounting requirements align with the 31x16.5 mm form factor before integration into final assemblies.

Selection Notes

Select this component when a compact, low-cost general purpose speaker is required for basic audio signaling. The 4-ohm impedance matches standard amplifier outputs commonly found in portable devices. Consider the limited high-frequency response above 7 kHz if full-range music reproduction is necessary, as this unit is optimized for voice or tone generation rather than wideband fidelity.

Part Context

Seltech specializes in electromechanical solutions including acoustic components. This model belongs to their line of round loudspeakers designed for cost-effective integration. The product is currently listed as active in distribution channels, indicating ongoing availability for new designs requiring small-form-factor audio output.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. When sourcing alternatives, match the 4-ohm impedance, 3-watt rating, and 31mm diameter to ensure mechanical and electrical compatibility without redesigning the enclosure or driver circuit.
