Crystals Procurement Notes

Verify the exact datasheet version and RoHS compliance status directly with the manufacturer or authorized distributor before procurement. Ensure the ordering suffix matches the required frequency tolerance and stability specifications for the target application. Confirm that the HC49USM5 footprint aligns with the PCB layout to avoid mechanical interference.

Crystals Selection Notes

Select this component when a low-profile SMD crystal is required to replace through-hole HC49US units without changing the pinout significantly. Consider the thermal profile limits during reflow soldering. Evaluate the equivalent series resistance (ESR) against the oscillator circuit's drive capability to ensure reliable startup and long-term stability under operating conditions.

Crystals Part Context

This part belongs to the HC49USM5 series, representing a thin, surface-mountable quartz crystal. It serves as a modern alternative to bulkier through-hole crystals, facilitating miniaturization in portable devices and dense PCB layouts while maintaining the reliability associated with metal-can-style ceramic packages.

Crystals Replacement Considerations

Direct replacement requires verifying the footprint compatibility with existing HC49USM5 pads. If substituting from other manufacturers, confirm identical load capacitance and ESR values to prevent frequency drift or failure to oscillate.
