Procurement Notes

Verify the specific datasheet version when ordering, as manufacturer documentation may list varying power ratings (250 mW vs 500 mW) or temperature ranges across different revisions. Confirm the exact package type, such as bulk or box, directly with the supplier prior to purchase to ensure compatibility with assembly processes.

Selection Notes

Select this component for applications requiring a compact 50 mm round speaker with high sensitivity. The 8 Ohm impedance suits standard audio driver circuits. Ensure the mounting space accommodates the 20.5 mm height and that the operating environment stays within the specified thermal limits.

Part Context

This model belongs to the DB Unlimited SP series of general-purpose dynamic speakers. These components are engineered for reliability in critical signaling roles. The series typically offers various impedances and mounting styles to meet diverse industrial requirements.

Replacement Considerations

SP570408-2 shares similar physical dimensions but differs in electrical specifications. Verify impedance and sensitivity matches before substitution. No direct official cross-reference is confirmed in public data.
