Speakers Procurement Notes

Verify the specific revision and packaging configuration directly with Knowles or authorized distributors before ordering. Confirm that the top-port orientation matches the mechanical constraints of the target enclosure. Ensure compatibility with standard reflow soldering profiles for small surface-mount components.

Speakers Selection Notes

Select this component when high sensitivity and compact size are required in constrained spaces. The 43-ohm impedance suits specific driver circuits. Evaluate the 101 dB SPL output against the required acoustic performance. Consider the rectangular footprint for PCB layout efficiency compared to circular alternatives.

Speakers Part Context

This part belongs to Knowles' portfolio of miniature balanced armature receivers. These components are engineered for high-fidelity audio reproduction in portable electronics. The HC series typically targets medical and hearing aid markets where reliability and miniaturization are critical.

Speakers Replacement Considerations

Check for HC-23764 variants with different port orientations or impedances. Verify if HC-23774-000 serves as a compatible alternative based on dimensional and electrical requirements.
