Procurement Notes

Verify the specific packaging configuration required for production, as this part number is available in tape and reel, cut tape, or Digi-Reel formats. Confirm that the selected variant matches the intended surface-mount reflow soldering profile. Ensure compatibility with the target PCB footprint dimensions of 5.00mm by 3.20mm during the procurement phase to avoid assembly issues.

Selection Notes

Select this component when a compact surface-mount crystal is required for 8 MHz applications. The CFPX-104 series offers a low-profile form factor suitable for space-constrained designs. Consider the 150 Ohm ESR value when designing the oscillator circuit to ensure proper startup conditions. The wide operating temperature range supports use in industrial or automotive environments where thermal stability is critical.

Part Context

This crystal belongs to the CFPX-104 series, which utilizes a seamed, sealed metal lid on a ceramic substrate. This construction method provides robust mechanical integrity and hermetic sealing against moisture and contaminants. The series is designed for high-volume surface-mount manufacturing, offering consistent performance across the industry-standard 4-SMD no-lead package format.

Replacement Considerations

The C5S-8.000-18-3030-X-R from Aker Technology Corp is documented as a similar replacement option. Verify pinout compatibility and physical dimensions before substitution.
