Crystals Procurement Notes

Verify the specific frequency tolerance requirements against the datasheet specifications, as variants may exist with different ppm ratings. Confirm that the 20pF load capacitance matches the host circuit's design parameters. Ensure the HC-49S package dimensions are compatible with the intended PCB layout and assembly processes before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 5 MHz fundamental frequency crystal is required for applications demanding high reliability across extreme temperatures. The 60 Ohm ESR value should be considered in relation to the oscillator circuit's drive level limitations. This part is suitable for designs where standard industrial grade performance and cost-effectiveness are prioritized over ultra-high precision or specialized packaging.

Crystals Part Context

This component belongs to the HKC crystal oscillator product line, which focuses on semiconductor display technologies and associated electronic components. The 49SMSS series typically utilizes the HC-49S package format, a common industry standard for through-hole mounted crystals. HKC manufactures these components to support various electronic equipment needs, including display drivers and general consumer electronics.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' 5 MHz HC-49S crystals with matching 20pF load capacitance and similar ESR values. Verify that any replacement part meets the same -40°C to +125°C operating temperature range and frequency stability requirements to ensure circuit compatibility.
