Oscillators Procurement Notes

Verify the specific suffix TCHSA0 against official Epson documentation to confirm pinout configuration and tolerance specifications. Ensure the operating temperature range meets system requirements, as variations exist within the SG-8101CA family. Cross-reference ordering codes with authorized distributors to avoid counterfeit components and ensure traceability.

Oscillators Selection Notes

Select this model when a precise 1.9521 MHz reference is required for CMOS-compatible circuits. Consider the ±20 ppm stability and 1.8V–3.3V supply range for compatibility with standard logic levels. Evaluate the 4-SMD package dimensions against PCB layout constraints. Confirm that the enable/disable functionality aligns with system power management strategies.

Oscillators Part Context

The SG-8101CA series represents Epson's line of standard CMOS oscillators designed for general timing applications. These devices offer stable frequency outputs with low power consumption profiles. The CA variant specifically denotes standard performance characteristics within the broader SG-8101 product family, targeting cost-sensitive and space-efficient electronic designs requiring reliable clock signals.

Oscillators Replacement Considerations

Direct substitutes include other SG-8101CA models with identical frequency and package dimensions, such as SG-8101CA 1.9584M-TCHSA0 if frequency tolerance allows. Verify electrical parameters and pin assignments before substitution. Generic replacements may lack the specific standby current characteristics or stability metrics of the original Epson component.
