Crystals Procurement Notes

Verify the specific ordering suffix against official ECS documentation to ensure correct packaging and tape specifications. Confirm that the requested variant matches the required frequency tolerance and load capacitance parameters for your circuit design. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Ensure the procurement channel provides valid traceability for quality assurance purposes.

Crystals Selection Notes

Select this component when a 25 MHz reference signal is required for space-constrained applications. The 10 pF load capacitance must match the oscillator circuit requirements specified in the host microcontroller or logic device datasheet. Consider the 50 Ohm ESR value for impedance matching during circuit design. Verify that the -40°C to +85°C temperature range meets the operational environment constraints of the final product.

Crystals Part Context

This crystal belongs to the ECX-1637B series of surface-mount devices. It serves as a frequency reference for digital clocks and timing circuits. The 4-SMD package allows for low-profile mounting on printed circuit boards. It replaces older through-hole variants where size reduction is necessary while maintaining similar electrical performance characteristics.

Crystals Replacement Considerations

Direct substitutes include other 25 MHz SMD crystals with identical 10 pF load capacitance and 4-SMD footprint. Verify that alternative parts meet the same ±10 ppm tolerance and -40°C to +85°C operating range. Check compatibility with existing PCB silkscreen and reflow soldering profiles before substitution.
