Procurement Notes

Verify the specific suffix codes on the ordering part number to confirm the exact load capacitance and packaging configuration required for your design. Ensure that the selected variant matches the target frequency and impedance specifications defined in the system schematic. Cross-reference the manufacturer's latest datasheet to confirm compliance with current environmental standards and RoHS directives before finalizing procurement orders.

Selection Notes

Select this component when a cost-effective, compact timing solution is required for microcontroller applications. The built-in capacitor eliminates the need for external discrete capacitors, reducing board space and assembly complexity. Consider the ±0.5% tolerance and ±0.3% stability metrics to ensure they meet the precision requirements of the target application compared to quartz crystal alternatives.

Part Context

This part belongs to the AWSCR-CPLA series of ceramic resonators manufactured by Abracon LLC. These components are designed as direct replacements for quartz crystals in many applications, offering lower cost and higher shock resistance. The series is characterized by its small footprint and integrated capacitor technology, making it suitable for mass-produced consumer devices where moderate frequency accuracy is sufficient.

Replacement Considerations

Direct substitutes include other Abracon AWSCR-CPLA variants with matching frequencies and capacitance values. Verify pinout compatibility and physical dimensions when considering alternative brands. Ceramic resonators generally offer different Q-factors and temperature characteristics compared to quartz crystals; ensure the replacement meets the system's jitter and drift requirements.
