Procurement Notes
Verify the specific datasheet version for the SP-4005-4Y to confirm current manufacturing status and compliance certifications. Ensure that the required sensitivity and impedance parameters match the target circuit design before finalizing procurement orders. Cross-reference official Soberton documentation to validate availability and technical specifications against supplier listings.
Selection Notes
Select this component when a compact 40mm dynamic speaker is required for applications needing 1W power handling. The 8 Ohm impedance suits standard low-voltage driver circuits. Consider the 83 dB sensitivity for volume requirements and the 450 Hz to 4.5 kHz frequency range for appropriate audio reproduction tasks in general purpose environments.
Part Context
This part belongs to the Soberton SP series of dynamic speakers. The model number indicates specific physical and electrical characteristics within the manufacturer's lineup. Similar variants may exist with different impedances or sensitivities, requiring careful distinction based on the suffix codes provided in official product catalogs.
Replacement Considerations
Direct substitutes must match the 40mm diameter, 8 Ohm impedance, and 1W power rating. Verify mounting dimensions and terminal configurations to ensure mechanical compatibility. Check sensitivity levels to maintain consistent acoustic performance in the original application.
