Procurement Notes

Verify the specific ordering suffix STD-CSY-1 against the latest NDK specification sheet to ensure compatibility with required frequency tolerances and temperature ranges. Confirm that the 12pF load capacitance matches the target oscillator circuit design. Check for any recent lifecycle status updates, as distribution channels may list obsolete or active statuses inconsistently. Ensure packaging requirements align with tape and reel handling procedures.

Selection Notes

Select this component when a 13.56MHz clock source is required for automotive or industrial applications demanding AEC-Q200 certification. The 120 Ohm ESR value must be compatible with the microcontroller's oscillation circuit gain capabilities. Designers should account for the 12pF load capacitance in PCB layout calculations to maintain frequency accuracy. Consider the 100 μW maximum drive level to prevent over-driving the crystal during operation.

Part Context

This part belongs to the NX5032SD series by NDK, which focuses on small surface-mount crystal units. The series is engineered to meet the stringent demands of automotive electronics, particularly for sensors and monitoring systems. It represents a standard solution for integrating precise timing into compact embedded systems where size and thermal resilience are critical constraints.

Replacement Considerations

Publicly confirmed substitute part numbers include ECS Inc. models such as ECS-135.6-10-30BQZ-TR and ECS-135.6-10-33QZ-TR. These alternatives offer similar 13.56MHz frequencies and SMD packaging but require verification of their specific AEC-Q200 compliance and ESR values against the original design requirements.
