Resonators Procurement Notes

Verify part authenticity against Panasonic official documentation due to discontinued status. Confirm that the specific suffix matches the required frequency tolerance and package variant. Check for alternative sources if original stock is unavailable, ensuring compatibility with existing PCB layouts and thermal requirements.

Resonators Selection Notes

Select this component when a compact, cost-effective timing solution is needed for 3 MHz applications. Ensure the operating environment stays within the specified -20°C to +80°C range. Verify that the integrated capacitor values align with the target oscillator circuit requirements without external loading adjustments.

Resonators Part Context

This component belongs to the EFO-MC series of ceramic resonators from Panasonic Industry. The series is characterized by built-in capacitors that simplify circuit design by reducing external component count. These devices are engineered for reliability in consumer electronics and industrial control systems where stable frequency generation is critical.

Resonators Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Due to the discontinued status, engineers should evaluate equivalent ceramic resonators with matching 3 MHz frequency, ±0.3% stability, and compatible package dimensions for direct replacement.
