SP-1303L

Overview

The SP-1303L is a general purpose dynamic speaker manufactured by Soberton Inc. It features an 8-ohm impedance and a rated power handling capacity of 500 mW. The device delivers a sound pressure level of 87 dBA and operates within a frequency range of 300 Hz to 8 kHz. It utilizes a top port location and has a round shape with wire lead termination.

Feature Summary

• Dynamic speaker unit designed for general purpose audio applications
• Round form factor with top port location for sound output
• Terminates via wire leads for direct circuit integration

Applications

• General purpose audio output devices
• Consumer electronics requiring compact speakers
• Industrial control panels with audio feedback needs

Procurement Notes

Verify the specific datasheet version for the SP-1303L to confirm exact mechanical dimensions and electrical tolerances. Ensure compatibility with the target circuit's voltage and current requirements. Check for RoHS compliance status if required by your manufacturing standards. Confirm that wire lead termination matches your assembly process.

Selection Notes

Select this component when an 8-ohm impedance and 500 mW power rating are required. The 87 dBA sensitivity indicates moderate efficiency suitable for low-power applications. Consider the 300 Hz to 8 kHz frequency response for voice or limited-bandwidth audio rather than full-range music reproduction. The round shape and top port dictate enclosure design constraints.

Part Context

Soberton Inc. specializes in micro-speakers and acoustic components. The SP-1303L belongs to their general purpose speaker lineup, distinct from high-fidelity or specialized hearing aid drivers. It represents a standard off-the-shelf solution for basic audio indication or communication tasks where size and cost are primary factors over audiophile-grade performance.

Replacement Considerations

The SP-1303L-1 and SP-1303L-2 are listed as related variants. Verify if these suffixes indicate changes in impedance, power handling, or physical mounting before substitution. Cross-reference datasheets to ensure identical frequency response and sensitivity profiles to avoid acoustic mismatch in the final assembly.
