Crystals Procurement Notes

Verify the exact package dimensions and pin configuration against the official datasheet before integration. Confirm that the 20 pF load capacitance matches your circuit design requirements. Ensure the operating temperature range specified by Suzhou Hangjing meets your environmental constraints. Request sample units to validate soldering compatibility with the 2-SMD flat lead form factor.

Crystals Selection Notes

Select this component when a 27.1412 MHz frequency is required with moderate stability. The 20 ppm tolerance suits general digital applications rather than high-precision RF systems. Consider the 2-SMD flat lead package for automated assembly processes. Compare ESR values with oscillator input impedance to ensure reliable startup conditions.

Crystals Part Context

This part belongs to the quartz crystal resonator category produced by Suzhou Hangjing Elec&Tech Co., Ltd., established in 2014. The manufacturer specializes in quartz frequency control units. The 0497S2 prefix indicates a specific series within their product line, likely denoting the package type and electrical characteristics consistent with their standard crystal offerings.

Crystals Replacement Considerations

Direct substitutes must match the 27.1412 MHz frequency, 20 pF load capacitance, 50 Ohm ESR, and 2-SMD flat lead package. Verify that alternative manufacturers provide identical ±20 ppm tolerance. Check mechanical footprint compatibility for PCB reflow soldering. No specific cross-reference part numbers are publicly confirmed in the provided source data.
