Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete WX72C50004 is based on the following critical parameters:

• Manufacturer: Diodes Incorporated (same manufacturer ensures design continuity and supply chain reliability)
• Product Type: XO (Standard) Oscillator with crystal base resonator
• Compliance Standards: RoHS Compliant and REACH Unaffected status maintained
• Moisture Sensitivity: MSL 1 (Unlimited) environmental rating preserved
• Regulatory Classification: EAR99 ECCN and 8542.39.0001 HTSUS code alignment

The NX7021E0125.000000 qualifies as a direct substitute based on matching manufacturer, oscillator type, resonator technology, and regulatory compliance framework. Both components operate within the same product ecosystem and certification environment.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Why is the WX72C50004 being replaced? A: The WX72C50004 has reached obsolete product status. The NX7021E0125.000000 is an active production alternative from the same manufacturer that maintains equivalent compliance, environmental ratings, and oscillator functionality.

Q: Are the WX72C50004 and NX7021E0125.000000 pin-compatible? A: Both components are XO (Standard) oscillators with crystal resonators manufactured by Diodes Incorporated. Compatibility must be verified against specific application circuit requirements, including frequency, output type, voltage supply, and package specifications.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant? A: ROHS3 Compliant represents the current regulatory standard for RoHS compliance. The substitute's ROHS3 status indicates alignment with the latest regulatory requirements while maintaining backward compatibility with RoHS Compliant applications.

Q: Are both parts REACH compliant? A: Both components carry REACH Unaffected status, indicating they are not subject to REACH regulatory restrictions and are suitable for applications requiring REACH compliance documentation.

Q: What is the MSL rating and why does it matter? A: MSL (Moisture Sensitivity Level) 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. Both the main part and substitute share this rating, ensuring equivalent environmental tolerance.

Q: Can I use the NX7021E0125.000000 as a direct drop-in replacement? A: The NX7021E0125.000000 qualifies as a functional substitute based on manufacturer, oscillator type, and compliance criteria. Physical integration requires verification of package type, mounting method, frequency specification, output characteristics, and voltage supply requirements for your specific application.
