Crystals Procurement Notes

Verify the specific suffix codes against official Suntsu documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with the target PCB footprint and thermal requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 25 MHz surface-mount crystal with 19 pF load capacitance is required. Confirm that the ±30 ppm stability meets system timing accuracy needs and that the HC-49/US form factor fits the available board space constraints.

Crystals Part Context

This part belongs to the SXTHM2 series of crystals from Suntsu Electronics. It shares similar physical dimensions and mounting styles with other variants in the series but differs in frequency and capacitance values. The series supports various standard frequencies for general-purpose timing applications.

Crystals Replacement Considerations

Direct substitutes include other 25 MHz SMD crystals with 19 pF load capacitance and compatible ESR. Verify pinout and mechanical dimensions match the HC-49/US specification to ensure proper fit without redesigning the footprint.
