Crystals Procurement Notes

Verify the specific suffix codes against official ECS documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with reflow soldering profiles specified in the datasheet. Confirm that the requested quantity matches the standard tape-and-reel packaging requirements. Cross-reference the part number with the latest revision history to avoid obsolete variants.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency crystal is required for automotive or industrial applications. The ±25 ppm tolerance suits most digital communication interfaces. Consider the 100 Ohm ESR value for oscillator circuit matching. The wide temperature range (-40°C to +125°C) makes it suitable for environments exceeding standard commercial limits.

Crystals Part Context

This part belongs to the ECX-37Q series of surface-mount crystals from ECS Inc. The series offers various frequency options within a standardized 2.00mm x 1.60mm footprint. The 'AES' suffix typically denotes specific packaging and compliance attributes. The series is designed for high-volume manufacturing and automated placement.

Crystals Replacement Considerations

Direct substitutes must match the 25 MHz frequency, 10pF load capacitance, and 4-SMD 2.00x1.60mm package. Verify equivalent ESR and temperature range specifications. Check for identical AEC-Q200 qualification if automotive use is required. No specific alternative part numbers are confirmed in public documentation.
