Crystals Procurement Notes

Verify the complete part number including the suffix against official manufacturer documentation to ensure correct specifications. Confirm that the required load capacitance matches the target circuit design. Check RoHS compliance status if environmental regulations apply to the specific manufacturing batch. Ensure the surface-mount footprint aligns with the PCB layout requirements before ordering.

Crystals Selection Notes

Select this component when a low-profile 1.6mm x 1.0mm crystal is required for portable electronics. The 12.5pF load capacitance must match the oscillator circuit's total stray capacitance. Consider the 90kOhm ESR value for compatibility with the driving circuitry. Verify that the ±20ppm tolerance meets the system's timing accuracy requirements across the specified temperature range.

Crystals Part Context

This part belongs to the 9HT12 series of quartz crystals from TXC Corporation. The series is characterized by small form factors optimized for consumer electronics. The 9HT12 designation indicates specific dimensional and electrical characteristics distinct from other series like the 9HT10. These components are widely used in devices requiring precise timekeeping or clock generation.

Crystals Replacement Considerations

Compatible substitutes include parts from the same 9HT12 series with identical electrical parameters. Verify that any replacement maintains the 1.6mm x 1.0mm footprint and 12.5pF load capacitance. Cross-reference datasheets to ensure equivalent ESR and frequency tolerance values are met for direct board-level interchangeability.
