Crystals Procurement Notes

Verify that the specific order matches the exact part number 10M20PI/49US to ensure correct frequency and package specifications. Confirm that the supplier provides official documentation or datasheets from YIC International Co Ltd. Check for any specific handling requirements related to quartz crystals during storage and installation. Ensure the purchasing channel is authorized to guarantee component authenticity and quality standards.

Crystals Selection Notes

Select this component when a 10 MHz reference with ±30ppm stability is required in a through-hole design. The HC-49/US package suits boards with standard drilling patterns. Consider the 20pF load capacitance requirement for oscillator circuit design. Evaluate the 50 Ohm ESR against the host oscillator's drive level specifications to prevent over-driving the crystal.

Crystals Part Context

This crystal belongs to YIC's standard MHz crystal lineup, utilizing the common HC-49/US form factor. It is distinct from surface-mount variants like the HC-49U series. The model designation indicates the 10 MHz frequency and 20pF load capacitance. It serves as a fundamental passive timing element in various digital electronics, differing from active oscillators by requiring an external oscillator circuit.

Crystals Replacement Considerations

Direct substitutes must match the 10 MHz frequency, HC-49/US package, 20pF load capacitance, and ±30ppm stability. Verify ESR compatibility with the existing circuit design. Cross-reference with other manufacturers offering identical electrical parameters and mechanical dimensions to ensure pin-out and footprint alignment.
