Crystals Procurement Notes

Verify the specific suffix 'M' against the manufacturer's official datasheet to confirm the exact ESR value and packaging configuration. Ensure the load capacitance requirement of your target oscillator circuit matches the 7 pF specification. Cross-reference the pinout diagram from the official Suntsu documentation to prevent soldering errors during PCB assembly. Confirm that the ±50 ppm stability meets your system's timing accuracy requirements before finalizing procurement.

Crystals Selection Notes

Select this component when a 25 MHz reference frequency is required with moderate stability. The 120 Ohm ESR must be compatible with the driving capability of the host oscillator IC. Consider the 4-SMD footprint dimensions for PCB layout constraints. Evaluate if the ±50 ppm tolerance is sufficient for the application environment, as tighter tolerances may require different series parts.

Crystals Part Context

This part belongs to the SXT2147 series of surface-mount crystals from Suntsu Electronics. The series typically offers various frequency options within the MHz range, sharing similar physical package dimensions but differing in electrical parameters such as frequency, ESR, and stability. The AA27 designation likely refers to specific case size or mounting characteristics within this product line.

Crystals Replacement Considerations

Direct substitutes include other 25 MHz crystals with identical 4-SMD no-lead footprints, 7 pF load capacitance, and comparable ESR values. Verify that any replacement part maintains the same operating temperature range and frequency stability specifications to ensure circuit compatibility.
