Crystals Procurement Notes

Verify the specific suffix 'I' against project requirements, as it denotes industrial temperature range specifications distinct from commercial variants. Confirm that the 18pF load capacitance aligns with the host circuit's design parameters. Ensure the 4-SMD package dimensions fit within the allocated PCB area. Cross-reference the datasheet for any recent product change notices affecting marking or material composition prior to final procurement authorization.

Crystals Selection Notes

Select this component when a 32 MHz fundamental frequency is required with strict ±30 ppm tolerance. The 18pF load capacitance must match the oscillator circuit design. Consider the -20°C to +70°C operating range suitability for the target environment. The 60 Ohm ESR value should be compatible with the driving circuit's power constraints. Verify package compatibility against existing footprints before integration into new designs.

Crystals Part Context

This part belongs to the CTS 403 Series, a line of general-purpose surface-mount crystals. The series provides various frequencies and packages optimized for consumer and industrial electronics. The 403I35D32M00000 specifically utilizes the standard 3.2x2.5mm footprint common in space-constrained applications. It serves as a direct replacement for older through-hole or larger SMD crystals requiring similar electrical characteristics.

Crystals Replacement Considerations

The 403C35D32M00000 is a documented direct substitute from the same manufacturer. Both parts share identical electrical specifications and package dimensions. Verify that the 'C' suffix variant meets the specific application requirements if sourcing alternatives.
