Procurement Notes

Verify the specific suffix 'B' against the manufacturer's current datasheet to confirm exact physical dimensions and lead configuration. Ensure the selected variant matches the required load capacitance and ESR specifications for the target circuit design. Confirm RoHS compliance status directly with the supplier documentation prior to procurement.

Selection Notes

Select this component when a 3.6864 MHz reference with ±30 ppm initial tolerance is required. The HC-49/4H package offers a standard form factor for through-hole assembly. Consider the 300 Ohm ESR value for oscillator circuit compatibility. Verify that the -20°C to +70°C temperature range meets the operational environment requirements.

Part Context

This part belongs to the HC-49/4H series of quartz crystals produced by IQD Frequency Products. These components are designed for general electronic applications requiring reliable frequency control. The series is characterized by hermetic sealing and robust mechanical construction suitable for various industrial and commercial environments.

Replacement Considerations

Direct substitutes must match the 3.6864 MHz frequency, 30 pF load capacitance, and HC-49/4H package. Verify equivalent ESR and tolerance ratings. Cross-reference with other manufacturers offering HC-49/US or HC-49/S packages if dimensional variations are acceptable.
