Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required load capacitance and tolerance specifications. Confirm that the package dimensions match the target PCB footprint. Check current availability status through authorized distributors as supply levels may fluctuate. Ensure compliance with RoHS directives if required by the end product regulations.

Crystals Selection Notes

Select this component when a small form factor is critical for space-constrained designs. The 40 MHz frequency is common for system clocks and communication baud rates. Consider the ±30 ppm tolerance for applications requiring moderate precision. The 10 pF load capacitance must match the oscillator circuit design. Evaluate thermal requirements against the -40°C to +85°C operational range.

Crystals Part Context

This part belongs to the 8Z series of seam-sealed crystals from TXC Corporation. These components are designed for general-purpose timing applications where size and stability are balanced. The series utilizes ceramic packaging to provide robust mechanical support and hermetic sealing. It serves as a passive frequency-determining element in electronic circuits.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz SMD crystals with identical 2.5x2.0mm dimensions and 10pF load capacitance. Verify equivalent ESR and stability ratings before substitution. Cross-reference with TXC's internal cross-reference guides for validated alternatives.
