BOX1-15121-L

Overview

The Seltech BOX1-15121-L is a general-purpose magnetic speaker designed for audio signal reproduction. It features an 8 Ohms impedance and a power handling capacity of 600 mW. The frequency range spans from 750 Hz to 20 kHz, with a self-resonant frequency at 750 Hz. The unit offers an efficiency of 73 dBA and utilizes a top port configuration. Physical dimensions are 20.00mm in length and 15.00mm in width, with termination provided via wire leads equipped with a connector.

Feature Summary

• Magnetic technology construction for reliable audio output
• Top port design for directional sound projection
• Wire lead termination with integrated connector for simplified assembly

Applications

• General purpose audio signal indication
• Electronic device status alerts
• Consumer electronics internal audio components

Procurement Notes

Verify the specific connector type included with the wire leads prior to integration, as this affects PCB or harness compatibility. Confirm that the 600 mW power rating aligns with the target circuit's output capabilities to prevent thermal damage. Ensure the 8 Ohms impedance matches the driving source requirements for optimal performance and efficiency.

Selection Notes

Choose this component when a compact rectangular speaker with top porting is required for general audio tasks. The 750 Hz lower frequency limit makes it suitable for mid-range frequencies rather than deep bass applications. Consider the physical size constraints of 20.00mm x 15.00mm during enclosure design to ensure proper acoustic coupling and mounting space.

Part Context

This model belongs to Seltech's line of small form factor speakers. It is distinct from waterproof variants like the LR1508L025YN8WP due to its standard environmental rating. The product is currently active and serves as a standard solution for non-specialized audio feedback in compact electronic assemblies.

Replacement Considerations

Direct substitutes must match the 8 Ohms impedance, 600 mW power rating, and similar physical dimensions. Verify that alternative models support the same top port orientation and wire lead termination style to maintain mechanical and electrical compatibility without redesigning the host system.
