Crystals Procurement Notes

Verify the specific suffix DC48 against official Suntsu documentation to confirm package dimensions and pinout compatibility. Ensure the required frequency tolerance of ±20 ppm meets system specifications. Cross-reference the 19 pF load capacitance with circuit design requirements. Confirm availability through authorized distributors as stock levels fluctuate. Request updated datasheets for latest manufacturing revisions.

Crystals Selection Notes

Select this component when a 27 MHz clock source is required with ±20 ppm tolerance. Verify that the 19 pF load capacitance matches the oscillator circuit design. Ensure the 4-SMD no-lead package fits the PCB footprint constraints. Confirm the -40°C to +85°C temperature range satisfies environmental conditions. Compare ESR of 80 Ohms against driver capability limits.

Crystals Part Context

This part belongs to Suntsu Electronics' SXT series of surface-mount crystals. The series offers various frequencies and packages for general-purpose timing applications. The DC48 suffix indicates specific physical dimensions and terminal configuration. Similar models exist with different frequencies or tolerances within the same product family.

Crystals Replacement Considerations

Direct substitutes require matching 27 MHz frequency, 19 pF load capacitance, and 4-SMD no-lead package. Verify equivalent ESR and temperature range specifications. Check manufacturer-specific mounting recommendations for no-lead components. Consult official cross-reference guides for approved alternatives.
