Crystals Procurement Notes

Verify the specific suffix codes against official Suntsu documentation to ensure correct tolerance and temperature ratings. Confirm package dimensions match design constraints. Request updated datasheets directly from authorized distributors to validate current manufacturing status and availability before finalizing procurement plans.

Crystals Selection Notes

Select this component when a 12 MHz reference is required in an HC-49/US footprint. Ensure the circuit design accommodates the 18pF load capacitance requirement. Verify that the ±10ppm initial tolerance meets system accuracy needs. Check thermal requirements against the operational range specifications provided in the technical data sheet.

Crystals Part Context

This part belongs to the SXTHM2 series of surface mount crystals from Suntsu Electronics. The series offers various frequencies and tolerances in standardized packages. The FC074 designation indicates specific electrical parameters within this product line. It serves as a direct replacement for through-hole equivalents in space-constrained designs.

Crystals Replacement Considerations

Direct substitutes include other 12 MHz crystals in HC-49/US packages with matching 18pF load capacitance. Verify equivalent series resistance and stability ratings. Cross-reference pinout compatibility if mechanical integration differs. Consult manufacturer cross-reference lists for verified alternative part numbers.
