Procurement Notes

Verify the specific suffix codes against the official NDK datasheet to ensure compatibility with required temperature ranges and tolerance levels. Confirm that the ordering part number matches the exact frequency and package variant needed for your design. Request manufacturer documentation directly from NDK or authorized distributors to validate authenticity and technical specifications before finalizing procurement decisions.

Selection Notes

Select this component when a fundamental frequency of 4.194304 MHz is required with ±50 ppm stability. Ensure the application environment stays within the -10°C to +70°C operating range. Verify that the circuit can support the 12 pF load capacitance and 50 ohm ESR characteristics. Confirm that the surface-mount footprint dimensions align with the PCB layout constraints.

Part Context

This part belongs to the NX1255GB series of surface-mount crystal units from NDK. The series offers various frequency options within the fundamental range, sharing common physical dimensions and mounting characteristics. The GB suffix typically denotes specific tolerance and temperature performance variants within the broader NX1255 product family.

Replacement Considerations

Direct substitutes must match the 4.194304 MHz frequency, 12 pF load capacitance, and 50 ohm ESR. Verify that alternative components support the same ±50 ppm tolerance and operate within the -10°C to +70°C range. Ensure the replacement uses the identical 11.8 x 5.5 x 2.5 mm surface-mount package for mechanical compatibility.
