SP-5090-4Y

Overview

The SP-5090-4Y is a general-purpose rectangular speaker manufactured by Soberton Inc. It features an 8-ohm impedance and a rated power of 10 watts, with a maximum power handling of 20 watts. The device delivers a sound pressure level of 96 dBA at 1 meter for 1 watt input. Its frequency response ranges from 270 Hz to 20 kHz, with a self-resonant frequency of 270 Hz. The speaker utilizes a top port location and solder eyelet termination. Physical dimensions are approximately 90mm x 50mm, with a height of 15mm.

Feature Summary

• Rectangular form factor designed for compact audio applications
• Top port configuration for directed sound projection
• Solder eyelet termination for secure circuit board mounting
• High efficiency output with 96 dBA sensitivity

Applications

• General purpose audio reproduction in consumer electronics
• Embedded systems requiring compact rectangular speakers
• Industrial automation equipment audio alerts
• Electronic devices needing reliable mid-range frequency output

Procurement Notes

Verify the exact impedance specification against the official datasheet, as some sources list 4 ohms while others indicate 8 ohms. Confirm the physical dimensions match your enclosure requirements, noting the rectangular shape and top port orientation. Ensure solder eyelet termination compatibility with your PCB design. Check RoHS compliance status if required for your specific manufacturing standards.

Selection Notes

Select this component when a rectangular speaker shape is required for space-constrained designs. Consider the 96 dBA sensitivity for applications needing high volume output without excessive amplification. The top port location suits designs where sound directionality is important. Verify that the 270 Hz low-frequency response meets your audio quality requirements, as it may not reproduce very low bass frequencies effectively.

Part Context

This speaker belongs to Soberton Inc.'s general-purpose audio product line, designed for cost-effective integration into various electronic devices. The rectangular shape distinguishes it from circular counterparts, offering different mounting and acoustic characteristics. As a standard component, it provides reliable performance for non-critical audio applications where size and cost are primary considerations.

Replacement Considerations

Direct substitutes include CMS-4049-28S from Same Sky, which offers similar specifications. When replacing, verify impedance matching and physical dimension compatibility. Ensure the replacement maintains the same termination type and port location to avoid redesigning the enclosure or PCB layout.
