Procurement Notes

Verify the specific packaging configuration against project requirements, as bulk packaging may differ from reel options. Confirm that the HC-49 form factor aligns with PCB layout constraints. Ensure the operating temperature range meets environmental specifications. Cross-reference the exact part number suffix to confirm availability status, as some variants may be discontinued or subject to supply limitations.

Selection Notes

Select this component when a standard through-hole quartz crystal is required for frequencies around 3.6864 MHz. Consider the HC-49 package size for assembly compatibility. Evaluate the ±30 ppm tolerance against system jitter requirements. Compare the 1 mW drive level with oscillator circuit capabilities to prevent overdriving. Assess the -20°C to 70°C range against ambient conditions.
