Procurement Notes

Verify the specific suffix 'CRLB' against the manufacturer's current datasheet to confirm the exact tolerance and stability specifications, as these parameters can vary significantly between similar part numbers within the same family. Ensure the ordering quantity aligns with standard reel packaging requirements defined by the supplier. Cross-reference the RoHS compliance status directly with the official documentation provided by Abracon LLC prior to final procurement decisions.

Selection Notes

Select this component when a cost-effective alternative to quartz crystals is required for moderate precision timing needs. The integrated capacitor feature eliminates the need for external load capacitors, reducing board space and assembly complexity. Consider the 40 Ohm impedance characteristics to ensure compatibility with the driving circuitry of the target microcontroller or oscillator IC. Verify that the operating temperature range meets the environmental requirements of the end application.

Part Context

This ceramic resonator belongs to Abracon's AWSCR series, which focuses on providing reliable timing solutions for mass-produced consumer and industrial electronics. The series is characterized by its ability to offer better stability than simple RC oscillators while maintaining lower costs compared to traditional quartz crystal units. It serves as a critical component in systems where precise frequency control is necessary but extreme accuracy is not paramount.

Replacement Considerations

AWSCR-7.37CRLA-C15-T3 is a documented variant within the same product line. Verify if the 'A' suffix indicates a different tolerance or stability specification compared to the 'B' suffix before substitution. Ensure the replacement maintains the same 15 pF load capacitance and 7.37 MHz frequency to guarantee circuit functionality without redesign.
