Crystals Procurement Notes

Verify the manufacturer designation carefully, as the part number appears associated with HKC in distributor listings while similar HC-49SM components are often produced by specialized crystal manufacturers like Oscilent. Confirm the specific electrical parameters, particularly the series resistance value of 130 Ohms versus alternative 100 Ohm variants, against the official datasheet before integration. Ensure the 18 pF load capacitance matches the target circuit design requirements to maintain the specified ±25 ppm frequency accuracy.

Crystals Selection Notes

Select this component when a precise 4.096 MHz reference is required for surface-mount designs. The 18 pF load capacitance dictates compatibility with specific oscillator circuit topologies. The 130 Ohm series resistance influences the required drive strength from the host oscillator. Consider the -10 °C to +60 °C operating temperature range for environmental suitability. The tape and reel format supports automated assembly processes.

Crystals Part Context

This component belongs to the 49SM series of quartz crystals, characterized by the HC-49SM physical footprint adapted for surface mounting. These parts serve as fundamental frequency references in electronic systems requiring stable clock signals. The specific model denotes a 4.096 MHz output, a common frequency derived from binary division of higher base clocks.

Crystals Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Similar HC-49SM SMD crystals from other manufacturers may be considered if they match the 4.096 MHz frequency, 18 pF load capacitance, and ±25 ppm tolerance specifications.
