Crystals Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Confirm end-of-life status or availability through authorized distributors prior to finalizing procurement plans.

Crystals Selection Notes

Select this component when a small form factor is required alongside moderate frequency stability. The 6 pF load capacitance must match the oscillator circuit requirements. Verify that the 150 Ohm ESR aligns with the host system's drive level specifications to ensure reliable oscillation without overdriving the crystal.

Crystals Part Context

This part belongs to the TXC 7R series of miniature SMD crystals. The series is characterized by its glass-sealed ceramic package, which provides superior hermeticity compared to standard epoxy-sealed alternatives. It targets applications where space constraints are critical but environmental robustness remains a priority.

Crystals Replacement Considerations

Direct substitutes include the QT325G-27.120MAHV-T from QST, which offers parameter equivalence. Verify pinout compatibility and mechanical dimensions before substitution to ensure seamless integration into existing designs.
