Crystals Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm the exact package variant and termination style. Ensure that the selected component matches the required load capacitance and ESR specifications for the target circuit design. Cross-reference the operating temperature range with the application environment requirements to guarantee reliable performance under all expected conditions.

Crystals Selection Notes

Select this component when a 16 MHz fundamental frequency crystal is required in an HC-49/US compatible surface mount package. Consider the ±30 ppm stability requirement and the -20°C to +70°C operating range. Verify that the 20 pF load capacitance aligns with the host circuit's capacitive load requirements. Confirm that the 40 Ohm ESR is acceptable for the oscillator circuit's drive level constraints.

Crystals Part Context

This part belongs to the family of MHz crystals manufactured by YIC. It shares the HC-49/US mechanical outline characteristics but is configured for surface mount technology. The 16M20P2/49SMT designation indicates the 16 MHz frequency, 20 pF load capacitance, and specific package type. It serves as a timing reference element in electronic systems requiring precise frequency generation.

Crystals Replacement Considerations

Direct substitutes include parts with identical electrical parameters and mechanical footprint. Verify compatibility with alternative manufacturers offering 16 MHz crystals in HC-49/US SMD packages with 20 pF load capacitance and similar stability ratings.
