Crystals Procurement Notes

Verify the specific ordering suffix AA07 against the manufacturer's current datasheet to confirm pinout compatibility and material composition. Ensure that the required frequency tolerance of ±25 ppm meets the system design specifications before finalizing procurement orders. Cross-reference the package dimensions with the PCB footprint library to prevent mechanical interference during assembly.

Crystals Selection Notes

Select this component when a 27 MHz reference is required for cost-sensitive designs without stringent long-term aging requirements. The ±50 ppm stability is suitable for general-purpose digital logic but may be insufficient for high-precision RF synchronization tasks. Consider the 100 Ohm ESR value to ensure proper oscillator circuit loading and startup conditions are met within the target application environment.

Crystals Part Context

This part belongs to the SXT214 series of surface-mount crystals from Suntsu Electronics. The series offers various frequency options and package styles tailored for consumer and industrial electronics. The SXT21420AA07 variant specifically targets applications requiring a balance between performance and size, utilizing standard leadless packaging for efficient board space utilization.

Crystals Replacement Considerations

Direct substitutes must match the 27 MHz frequency, 20 pF load capacitance, and 4-SMD no-lead package. Verify that alternative components maintain equivalent ESR values and frequency stability limits to ensure circuit compatibility without redesigning the oscillator network.
