Cross-reference the manufacturing date code and RoHS compliance status with current supplier documentation before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 16 MHz fundamental crystal with ±20 ppm stability is required in an HC-49/US SMD form factor. Consider the 50 Ohm ESR and 12 pF load capacitance requirements for circuit compatibility. Evaluate thermal stability needs against the specified operating temperature range to ensure reliability under intended operational conditions.

Crystals Part Context

This part belongs to the Suntsu Electronics crystal resonator family, specifically designed for surface-mount applications. It complements other variants in the SXTHM series that offer different frequencies or tolerance levels. The HC-49/US style provides a standardized footprint compatible with existing PCB layouts, offering a direct replacement for through-hole versions where space constraints necessitate surface mounting.

Crystals Replacement Considerations

Direct substitutes include other 16 MHz HC-49/US SMD crystals with matching 12 pF load capacitance and similar ESR values. Verify that alternative manufacturers provide comparable ±20 ppm tolerance and identical mechanical dimensions to ensure fitment. Confirm that the replacement part supports the same fundamental mode operation and temperature range specifications.
