SP-1511L-2

Overview

The SP-1511L-2 is a rectangular dynamic speaker unit designed for mobile telephone applications. It features an 8 Ohm impedance and a frequency range of 100 Hz to 20 kHz. The component delivers a sensitivity of 91 dBA with a rated power of 700 mW and a maximum short-term power of 1000 mW. Dimensions are 15.00mm x 11.00mm with a height of 4.00mm. It utilizes Nd-Fe-B magnets and PEEK cones, offering top port location and solder pad termination.

Feature Summary

• Rectangular form factor optimized for compact mobile device integration
• High sensitivity output of 91 dBA for efficient audio performance
• Robust construction using PEEK cone material and Nd-Fe-B magnet

Applications

• Mobile telephones
• Portable communication devices
• Compact consumer electronics requiring small form factor speakers

Procurement Notes

Verify the specific suffix designation against the manufacturer's current datasheet to ensure correct sensitivity and power ratings. Confirm that the 100 Hz to 20 kHz frequency response aligns with your acoustic design requirements rather than the narrower 300 Hz to 5 kHz range found in similar model variants. Ensure solder pad compatibility with your assembly process.

Selection Notes

Select this model when high sensitivity (91 dBA) is required within a strict 15x11mm footprint. It is suitable for applications needing a broader frequency response down to 100 Hz compared to standard general-purpose variants. Verify that the 8 Ohm impedance matches your amplifier output stage capabilities for optimal power transfer.

Part Context

This component belongs to the SP Micro Speaker series by Soberton Inc., specifically engineered for mobile telephone use. It shares dimensional similarities with other models in the series but differs in acoustic parameters such as sensitivity and frequency range. The series emphasizes compactness and reliability for portable electronic devices.

Replacement Considerations

The SP-1511S-5 is a related variant but offers lower sensitivity (82 dBA) and a narrower frequency range (300 Hz ~ 5 kHz). Substitution requires evaluating if the reduced sensitivity and bandwidth meet system requirements. Direct electrical replacement is possible due to identical 8 Ohm impedance and dimensions.
