Procurement Notes
Verify the specific load capacitance requirements against your circuit design before procurement. Confirm that the third lead connection is supported by your PCB footprint. Ensure the operating temperature range aligns with your application environment. Check for any specific aging specifications if long-term frequency stability is critical. Validate RoHS compliance documentation if required by your supply chain regulations.
Selection Notes
Select this component when a standard 8 MHz reference is needed with enhanced grounding via the third lead. Consider the HC-49/U form factor for compatibility with existing footprints. Evaluate the trade-off between cost and performance compared to oscillator alternatives. Ensure the voltage and current parameters of your driving circuit match the resonator's characteristics. Compare alternative frequencies if system requirements change.
Part Context
This part belongs to MtronPTI's line of HC-49/U crystal resonators. These components are widely used in electronics for providing stable clock signals. The series offers various frequency options within the same physical package. The third lead variant distinguishes itself from standard two-lead designs by offering better noise immunity. This family supports both leaded and surface mount technologies depending on the specific suffix.
Replacement Considerations
Direct substitutes must match the 8.000000 MHz frequency and HC-49/U package dimensions. Verify that replacement parts also include the third ground lead. Check for equivalent load capacitance and drive level specifications. Ensure the replacement maintains RoHS compliance. Consult manufacturer datasheets for pinout and electrical parameter equivalence.
