Oscillators Procurement Notes

Verify the specific suffix TCHSA0 against official Epson documentation to confirm pinout configuration and tape/reel packaging specifications. Ensure the requested frequency matches the exact decimal precision required by the system design. Cross-reference the manufacturing date code to ensure component availability aligns with production schedules. Confirm that the 4-SMD no-lead package dimensions fit the designated PCB footprint without mechanical interference.

Oscillators Selection Notes

Select this component when a stable 10.3448 MHz reference is required for CMOS-based digital logic. The wide voltage tolerance allows flexibility in power supply design across 1.8V and 3.3V domains. Consider the low standby current if battery life or power efficiency is critical. Verify that the ±20ppm stability meets the timing jitter requirements of the target application interface.

Oscillators Part Context

This model belongs to the SG-8101 series of standard clock oscillators from Epson Timing. The series is characterized by its small form factor and broad voltage compatibility. The SG-8101CE variant specifically denotes the commercial grade version with defined performance limits for general electronic equipment. It serves as a direct replacement for larger crystal units in space-constrained designs.

Oscillators Replacement Considerations

Direct substitutes must match the 10.3448 MHz frequency, CMOS output type, and 4-SMD package. Verify equivalent electrical parameters including supply voltage range and current consumption. Check thermal ratings to ensure compatibility with the -40°C to +105°C operating window. Consult manufacturer cross-reference lists for approved alternative part numbers.
