• Industry standard leaded package design compatible with traditional through-hole assembly processes
• Parallel fundamental resonance mode operation optimized for stable clock signal generation

Applications

• Microcontroller clock source circuits
• Real-time clock modules
• Digital communication interfaces
• Industrial control systems

Procurement Notes

Verify the specific load capacitance requirement against the target circuit design, as datasheets indicate variations between 7 pF and 12 pF for this part number. Confirm that the through-hole HC-49 package dimensions align with the PCB footprint constraints. Ensure the operating temperature range meets the application's environmental specifications before finalizing procurement.

Selection Notes

Select this component when a standard 3.2768 MHz reference is required for through-hole applications. Consider the 30 ppm tolerance and 50 PPM stability metrics relative to system timing accuracy needs. Evaluate the 500 µW drive level to prevent over-driving the crystal. Compare physical dimensions against available board space for leaded packages.

Part Context

This part belongs to the LFXTAL series of parallel fundamental quartz crystals from IQD Frequency Products. The series offers various frequencies and packaging options, including surface mount and through-hole variants. This specific model represents a common low-frequency reference point widely used in digital electronics for timekeeping and synchronization tasks.

Replacement Considerations

Cross-reference with other manufacturers offering 3.2768 MHz crystals in HC-49 packages. Verify equivalent electrical parameters such as load capacitance, tolerance, and drive level. Check for compatibility with existing manufacturing processes and PCB layouts when substituting with alternative brands.
