Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct frequency tolerance and packaging specifications. Confirm RoHS3 compliance status if required by your supply chain regulations. Cross-reference the part number with authorized distributors to avoid counterfeit components. Ensure the load capacitance matches your circuit design requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 12 MHz fundamental frequency is required with tight stability over a wide temperature range. The HC-49/US package is suitable for PCB designs utilizing through-hole mounting technology. Consider the 40 Ohm ESR value for oscillator circuit compatibility. This part is appropriate for applications demanding high reliability without the need for surface-mount form factors.

Crystals Part Context

This part belongs to the HKC 49US Series of HC-49US through-hole crystals. The series covers a frequency range from 3.01 MHz to 100.00 MHz. These components are characterized by high reliability and low cost, making them common choices for mass-produced electronic equipment requiring stable timing references.

Crystals Replacement Considerations

Compatible substitutes must match the 12 MHz frequency, 12 pF load capacitance, and HC-49/US package dimensions. Verify that alternative parts support the same -40°C to +125°C operating temperature range and similar ESR values to ensure circuit performance parity.
