Procurement Notes

Verify the complete ordering part number to ensure correct frequency, tolerance, and packaging specifications. Confirm that the selected variant matches the required load capacitance and ESR values for the target oscillator circuit. Check for specific suffix codes that may indicate custom parameters or tape-and-reel packaging configurations before finalizing procurement orders.

Selection Notes

Select this component when a small form factor is critical for wireless IoT or portable device designs. Ensure the host microcontroller's internal oscillator circuit can drive the specified 80 Ohm ESR at 40 MHz. Verify that the 7 pF load capacitance aligns with the system's stray capacitance requirements to maintain the ±10 ppm accuracy specification.

Part Context

This model belongs to the NDK NX1612AA series of miniature crystal units. The series is engineered specifically for modern consumer electronics and wireless communication devices where board space is limited. It serves as a precise clock source for digital signal processing and radio frequency modulation in compact hardware architectures.

Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 7 pF load capacitance, 80 Ohm ESR, and 1612 package dimensions. Verify thermal stability and aging rate specifications if replacing with components from other manufacturers to ensure equivalent long-term performance.
