Procurement Notes
Verify current availability status carefully as the component is marked as no longer manufactured. Confirm that any remaining stock meets the required quality standards and RoHS compliance specifications before finalizing procurement decisions. Check for potential supply chain disruptions related to the piezoelectric element supplier changes noted in recent product notifications.
Selection Notes
Consider alternative models within the BL or BU series if this specific part is unavailable. Evaluate whether the 1.3 V rated voltage and analog output characteristics align with the target system's interface requirements. Ensure that the omnidirectional pickup pattern suits the intended acoustic environment and noise rejection needs.
Part Context
This microphone belongs to Knowles' broader portfolio of piezoelectric acoustic sensors. The BL series typically targets cost-sensitive applications requiring reliable analog audio capture. Recent process change notifications indicate shifts in piezoelectric element suppliers for this series, which may affect long-term sourcing strategies for design engineers.
Replacement Considerations
Consult official Knowles documentation for qualified substitute part numbers within the BL or BU series. Verify electrical compatibility and mechanical footprint alignment before transitioning designs to alternative components.
