Crystals Procurement Notes

Verify the specific suffix DA27 against official Suntsu Electronics documentation to confirm exact temperature range and stability ratings, as variations exist within the SXT2247 series. Ensure the requested quantity matches available stock levels from authorized distributors. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement orders to meet regulatory standards.

Crystals Selection Notes

Select this component when a 20 MHz surface-mount crystal with 7 pF load capacitance is required. Consider the 80 Ohm ESR value for impedance matching in the oscillator circuit. Verify that the operating temperature range meets the application environment requirements. Compare physical dimensions of the 4-SMD package against PCB footprint constraints to ensure mechanical fit during layout design.

Crystals Part Context

This part belongs to the SXT224 series of crystals from Suntsu Electronics, Inc. The series offers various frequency options and package configurations tailored for consumer electronics and industrial equipment. The DA27 suffix typically denotes specific packaging and reliability characteristics within this product line, distinguishing it from other variants like CA07 or DD38 which may have different stability or temperature specifications.

Crystals Replacement Considerations

Direct substitutes must match the 20 MHz frequency, 7 pF load capacitance, and 4-SMD no-lead package form factor. Verify equivalent ESR values to maintain circuit stability. Cross-reference pinout definitions if alternative manufacturers offer similar packages. Ensure replacement parts meet the same frequency tolerance and temperature range specifications to guarantee functional interchangeability.
