Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct tolerance and packaging specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Cross-reference the full part number with authorized distributors to validate availability and authenticity. Ensure the selected variant matches the required load capacitance and frequency stability for the target application circuit.

Crystals Selection Notes

Select this component when a 40 MHz reference signal is required within a constrained PCB area. The 12 pF load capacitance must match the oscillator circuit design parameters. Consider the ±30 ppm tolerance for applications requiring moderate frequency accuracy. Verify that the 60 Ohm ESR aligns with the driving circuit's capability to sustain oscillation without excessive power dissipation.

Crystals Part Context

This part belongs to the 8Z series of quartz crystals from TXC Corporation. The series offers various frequency options and package sizes tailored for consumer electronics and industrial applications. The 8Z designation indicates a specific form factor and manufacturing process optimized for high-volume surface mount production lines.

Crystals Replacement Considerations

Direct replacements include other 40 MHz SMD crystals with identical 3.2x2.5mm dimensions and 12pF load capacitance. Compatible alternatives from other manufacturers must match the 60 Ohm ESR and ±30 ppm tolerance specifications. Verify pinout compatibility and thermal characteristics before substituting.
