Procurement Notes

Verify the specific part number suffix against official NDK documentation to ensure correct frequency and tolerance specifications. Confirm that the required load capacitance matches the circuit design requirements. Check current lifecycle status as automotive components may undergo obsolescence notices. Ensure compliance with RoHS directives if applicable to the target market.

Selection Notes

Select this component when high-frequency stability is required in harsh thermal environments typical of automotive under-hood applications. The 12 pF load capacitance must be compatible with the host oscillator circuit's parasitic capacitance. Consider the ESR limits during matching network design to ensure reliable startup conditions across the full temperature range.

Part Context

This model belongs to the NX5032SD series, which is specifically engineered for automotive use cases requiring robust performance. The series is characterized by its small footprint and ability to maintain precise timing signals in demanding conditions. NDK manufactures these units using proprietary quartz cultivation technologies to ensure consistent quality and long-term reliability.

Replacement Considerations

ECS Inc. offers similar crystals such as the ECS-135.6-10-33QZ-TR, though frequency differences exist. Verify pin compatibility and electrical parameters before substitution. Consult NDK for officially recommended alternatives if this specific part is discontinued.
