Crystals Procurement Notes

Verify the specific suffix requirements against the official Fox Electronics C4ST Series datasheet to ensure compatibility with system load capacitance. Confirm that the HC-49/US form factor meets the PCB layout constraints. Check for any recent Product Change Notifications (PCNs) regarding material or manufacturing process updates before finalizing procurement orders.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for 8 MHz applications. Ensure the circuit design accounts for the 80 Ohms ESR and ±30ppm initial tolerance. Verify that the operating environment stays within the -20°C to +70°C range. Compare against other Fox Electronics series if tighter stability or different packaging is needed.

Crystals Part Context

This part belongs to the Fox Electronics C4ST series, formerly known as HC49SLF. It represents a standard line of through-hole quartz crystals widely used in industrial and consumer electronics. The series provides reliable frequency control for basic timing applications requiring moderate stability.

Crystals Replacement Considerations

Cross-reference with other Fox Electronics parts in the C4ST family for alternative frequencies. Verify mechanical dimensions and electrical parameters against competitors like TXC or NDK before substitution.
