Procurement Notes

Verify the specific suffix J33DTSK against official manufacturer documentation to confirm exact pinout, tolerance, and packaging configuration. Ensure compatibility with existing PCB footprint dimensions and reflow soldering profiles. Cross-reference the RoHS status and MSL rating with current environmental compliance requirements before finalizing procurement orders.

Selection Notes

Select this component when a 28.63636 MHz clock source is required for 3.3V HCMOS logic circuits. Consider the ±20 ppm stability specification for applications where moderate frequency accuracy is sufficient. Evaluate the 5032 package size against available board space constraints. Confirm that the -40°C to +85°C operating range meets the environmental demands of the target deployment scenario.
