Procurement Notes

Verify the specific revision status as this part may be marked obsolete in some distributor catalogs. Confirm compatibility with existing PCB footprints and soldering profiles. Ensure supply chain sources provide authentic Knowles components to guarantee acoustic performance specifications. Check for alternative sourcing if original stock is unavailable due to lifecycle status.

Selection Notes

Select this component when high sensitivity and compact size are critical for the application. The 1.5 kOhm impedance requires appropriate driver circuitry matching. Consider the side port orientation during mechanical design to ensure proper acoustic coupling. Evaluate thermal management requirements for soldering processes given the small package dimensions.

Part Context

This model belongs to Knowles' portfolio of precision audio receivers. Balanced armature drivers are commonly used in hearing instruments and premium audio gear due to their efficiency and size advantages over dynamic drivers. The BK series typically targets applications demanding high fidelity in minimal space.

Replacement Considerations
