Procurement Notes
Verify the specific datasheet version from DB Unlimited or authorized distributors to confirm current RoHS compliance status and exact dimensional tolerances. Ensure the selected variant matches the required impedance and power handling for the target circuit. Cross-reference part numbers carefully as suffixes may indicate different electrical characteristics or packaging options.
Selection Notes
Select this component when a compact 50mm dynamic speaker is required for flush mounting applications. Consider the 8 Ohm impedance and 1W power rating against the amplifier output capabilities. Verify that the 450Hz resonant frequency aligns with the desired acoustic performance profile for the specific device enclosure.
Part Context
This model belongs to the DB Unlimited SP series of dynamic speakers. The series offers various impedances and sound pressure levels suitable for diverse electronic applications. The SP500408-1 represents a standard configuration within this lineup, focusing on general-purpose audio signaling in constrained spaces.
Replacement Considerations
Direct substitutes include other DB Unlimited models such as SP500408-2 or SP500408-4, provided they match the 50mm diameter and 8 Ohm impedance requirements. Verify mechanical dimensions and mounting style compatibility before substitution.
