Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete WX72F62004 is based on the following critical parameters:

• Oscillator Type: Both the main part and substitute must be XO (Standard) oscillators with crystal base resonators
• Manufacturer Continuity: Diodes Incorporated maintains product line compatibility within the SaRonix-eCera™ family
• Regulatory Compliance: RoHS and REACH compliance status must be maintained or improved
• Packaging Classification: Surface mount technology with defined mechanical dimensions
• Supply Voltage and Output Characteristics: Electrical specifications must support the target application

The NX7021D0156.253906 from the SaRonix-eCera™ NX series meets these substitution criteria as an active, currently manufactured XO (Standard) oscillator from the same manufacturer.

Parameter Comparison

Engineering Selection Recommendations

The NX7021D0156.253906 is suitable as a substitute for the obsolete WX72F62004 based on the following factors:

• Active Product Status: The substitute is currently manufactured and supported by Diodes Incorporated, ensuring long-term availability and supply chain stability
• Regulatory Alignment: Both components maintain equivalent or improved compliance certifications (ROHS3 vs. RoHS Compliant, both REACH Unaffected)
• Manufacturer Consistency: Both oscillators are from Diodes Incorporated's SaRonix-eCera™ family, ensuring design philosophy and quality standards alignment
• Oscillator Classification: Both are XO (Standard) oscillators with crystal base resonators, maintaining functional equivalence
• Export Classification: Both components share the same ECCN (EAR99) and HTSUS code, simplifying procurement and regulatory documentation

Component selection must verify that the specific frequency (156.253906 MHz), output type (LVPECL), supply voltage (3.3V), and package dimensions (7.00mm x 5.00mm) are compatible with the target application requirements.

Frequently Asked Questions (FAQ)

Q: Why is the WX72F62004 no longer available? A: The WX72F62004 has reached end-of-life status and is classified as obsolete by Diodes Incorporated. Inventory is limited to existing stock. Active alternatives within the SaRonix-eCera™ product family are recommended for new designs and ongoing production.

Q: What are the key differences between the WX72F62004 and NX7021D0156.253906? A: The main differences are product status (obsolete vs. active), series designation (WX vs. NX), and specified electrical parameters. The substitute provides detailed frequency, output type, and supply voltage specifications that were not documented for the original part.

Q: Can the NX7021D0156.253906 be used as a direct replacement? A: Direct replacement requires verification that the application's frequency requirement is 156.253906 MHz, the output type is LVPECL, the supply voltage is 3.3V, and the package footprint (7.00mm x 5.00mm, 6-SMD No Lead) is compatible with the PCB design. Physical layout and electrical interface compatibility must be confirmed.

Q: Are there any compliance concerns with substitution? A: No compliance concerns exist. Both components maintain equivalent or improved regulatory status (ROHS3 Compliant vs. RoHS Compliant, both REACH Unaffected, both EAR99 classification). Substitution does not introduce additional compliance requirements.

Q: What is the moisture sensitivity level of the substitute? A: The moisture sensitivity level for the NX7021D0156.253906 is not specified in the provided data. This parameter should be obtained from the manufacturer's datasheet prior to implementation in moisture-sensitive applications.

Q: How does the package change affect PCB design? A: The WX72F62004 uses SEAM7050 packaging, while the substitute uses 6-SMD No Lead packaging with dimensions of 7.00mm x 5.00mm and a maximum seated height of 1.55mm. PCB footprint, trace routing, and component placement must be re-evaluated to accommodate the new package geometry.
