SP-4005Y

Overview

The SP-4005Y is a general-purpose magnetic speaker manufactured by Soberton Inc. It features an 8-ohm impedance and a rated power of 1 W, with a maximum power handling of 1.5 W. The device operates within a frequency range of 400 Hz to 5 kHz and delivers a sound pressure level of 88 dBA. Designed with a top port location and round shape, it utilizes solder pad termination for circuit integration. The diaphragm material is not explicitly specified in the provided data, but the magnet type is N38.

Feature Summary

• Top port acoustic design for directional sound projection
• Magnetic technology construction with N38 magnet material
• Solder pad termination for direct PCB mounting

Applications

• General purpose audio output devices
• Compact electronic enclosures requiring top-firing speakers
• Low-frequency reproduction applications within 400 Hz to 5 kHz range

Procurement Notes

Verify the specific datasheet version for exact mechanical dimensions and tolerance levels. Confirm RoHS compliance status if required for your assembly process. Ensure soldering parameters are compatible with the terminal type. Cross-reference part numbers carefully as suffixes may indicate variations in impedance or power rating.

Selection Notes

Select this component when a top-port configuration is required for spatial constraints. The 8-ohm impedance suits standard low-voltage audio circuits. Consider the 400 Hz lower frequency limit for bass response requirements. Verify that the 1 W power rating meets the system's continuous drive needs without exceeding the 1.5 W maximum.

Part Context

This model belongs to the SP Micro Speaker series from Soberton Inc., designed for compact audio solutions. It shares the physical form factor with other variants like the SP-4005S but differs in electrical characteristics such as frequency range and sensitivity. The series focuses on small footprint speakers for portable electronics.

Replacement Considerations

The CMS-4049-28S from Same Sky is listed as a substitute. Verify impedance, power handling, and dimensional compatibility before substitution. Other SP-4005 variants may differ in frequency response or sensitivity.
