Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific datasheet version provided by East Electronics or authorized distributors to confirm exact electrical tolerances and mechanical dimensions. Ensure the procurement channel supplies genuine components to guarantee compliance with RoHS standards and operational reliability within the specified temperature range. Cross-reference part numbers carefully as distributor listings may vary in description accuracy.

Alarms, Buzzers, And Sirens Selection Notes

Select this component for applications requiring a simple, low-voltage audible indicator. The 5V rating aligns with standard logic levels, while the 15.4mm form factor suits compact enclosures. Consider the 83dB SPL for environments where moderate volume is sufficient. Verify that the through-hole package matches the target PCB layout and that the operating temperature range covers the intended environmental conditions.

Alarms, Buzzers, And Sirens Part Context

This buzzer belongs to East Electronics' line of audio signaling components. It serves as a basic alert mechanism for electronic circuits. The model distinguishes itself through its specific dimensional profile and voltage characteristics compared to other series like the EFM-290EDFL. It represents a standard solution for non-programmable acoustic feedback in consumer electronics.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes must match the 5VDC rating, 4kHz frequency, and 15.4mm diameter. Verify that alternative parts support through-hole mounting and provide comparable sound pressure levels. Check for identical pin configurations and thermal ratings to ensure seamless integration without redesigning the host circuit board.
