Crystals Procurement Notes

Verify the specific suffix 'A23' against official CTS documentation to confirm the exact stability specification of ±30ppm and temperature range. Ensure the ordering part number matches the required load capacitance and package dimensions. Cross-reference the manufacturer's latest datasheet to confirm current production status and compliance certifications before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency with ±20 ppm tolerance is required in a compact SMD form factor. Consider the 16pF load capacitance compatibility with the target circuit design. Evaluate the -40°C to +85°C operating range against environmental conditions. Compare ESR values with oscillator drive requirements to ensure proper circuit performance and longevity.

Crystals Part Context

This part belongs to the CTS 445 series of glass-sealed crystals, which are mature legacy frequency control products. While still supported, these components are generally not recommended for new designs due to availability constraints. Engineers should review the product lifecycle status and consider updated alternatives if long-term supply assurance is critical for the application.

Crystals Replacement Considerations

Direct substitutes include 445I25C25M00000 and 445I23C25M00000 from CTS-Frequency Controls. Verify pinout compatibility and electrical parameter alignment before substitution. Consult official cross-reference lists for additional compatible parts.
