Speakers Procurement Notes

Verify the specific revision status as this component may be subject to lifecycle changes. Confirm RoHS3 compliance requirements against current project specifications. Ensure that the solder lug terminal type matches the intended PCB footprint or wire termination method. Validate that the 8-ohm impedance aligns with the driving circuit capabilities before finalizing procurement orders.

Speakers Selection Notes

Select this model when a compact, low-power acoustic solution is required. The 8-ohm impedance suits standard amplifier outputs. Consider the 80 dBA sensitivity for applications needing moderate volume without excessive drive current. The top porting orientation must fit the enclosure acoustic path. Verify that the 500 Hz lower frequency limit meets the application's bass response needs.

Speakers Part Context

This component belongs to the GA series of electronic speakers produced by Same Sky. The series focuses on providing reliable audio transducers for various industrial and consumer applications. The GA0451 specifically represents a standard size option within this lineup, balancing acoustic performance with physical constraints for embedded systems.

Speakers Replacement Considerations

No direct public substitute part numbers are documented for this discontinued item. Evaluate other models within the Same Sky GA series for similar impedance and dimension compatibility. Cross-reference with generic 8-ohm, 200 mW speakers if form factor flexibility exists.
