Crystals Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target circuit design before procurement. Confirm that the supplier provides original manufacturer documentation to ensure authenticity. Check for any specific handling instructions related to the surface mount package type during assembly processes.

Crystals Selection Notes

Select this component when a 14.31818 MHz reference signal is required with moderate stability specifications. Ensure the application circuit can support the 40 Ohm ESR characteristic. Verify that the HC-49/US footprint aligns with the PCB layout constraints and that the thermal environment remains within the specified -10°C to +70°C operational limits.

Crystals Part Context

This part belongs to the CSM1 series of low-profile surface mount crystals from Cardinal Components. The series offers various frequency options and package configurations tailored for cost-sensitive electronic applications. The CSM1 designation indicates a specific physical form factor distinct from other series like CSM4 or CSM5, which may feature different profiles or mounting styles.

Crystals Replacement Considerations

CSM1Z-A5B2C5-50-20.0D18 is listed as a parameter-equivalent alternative within the same manufacturer's portfolio, though frequency differences exist. Cross-manufacturer substitution requires strict verification of electrical parameters including frequency, ESR, and load capacitance.
