Substitute Part Grouping Explanation

Substitution of the WX51500003 is based on the following critical parameters:

• Manufacturer: Diodes Incorporated (same manufacturer ensures design continuity and support)
• Component Type: XO (Standard) Oscillator with Crystal base resonator
• Packaging Format: SEAM5032 surface mount package
• Compliance Standards: RoHS and REACH compliance maintained
• Regulatory Classification: EAR99 export control classification

The FD5000050 qualifies as a manufacturer-recommended substitute because it maintains the same manufacturer, component category, packaging standard, and regulatory compliance profile. Both components are crystal-based standard oscillators in compatible surface mount packages within the Diodes Incorporated SaRonix-eCera™ product family.

Parameter Comparison

Engineering Selection Recommendations

The FD5000050 is the manufacturer-recommended substitute for the obsolete WX51500003. Selection is justified on the following engineering basis:

• Manufacturer Continuity: Both components are manufactured by Diodes Incorporated, ensuring consistent design philosophy, quality standards, and technical support.
• Component Classification: Both are standard XO (Crystal Oscillator) devices with identical base resonator technology, ensuring functional equivalence in oscillator applications.
• Regulatory Compliance: The FD5000050 maintains RoHS3 compliance (enhanced from RoHS Compliant) and REACH Unaffected status, meeting current environmental and regulatory requirements. Both components share identical ECCN and HTSUS classifications.
• Product Status: The FD5000050 is Active, ensuring long-term availability, ongoing manufacturer support, and continued supply chain access compared to the obsolete WX51500003.
• Package Compatibility: Both components use SEAM5032 surface mount packaging, enabling direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the FD5000050 be used as a direct replacement for the WX51500003?

A: Yes, the FD5000050 is the manufacturer-recommended substitute. Both components share identical packaging (SEAM5032), manufacturer (Diodes Incorporated), component type (XO Standard Oscillator), and regulatory compliance profiles. PCB footprint compatibility is maintained.

Q: What are the key differences between these two oscillators?

A: The WX51500003 specifications are not fully detailed in available documentation. The FD5000050 provides complete specifications: 50 MHz frequency, 3.3V supply, HCMOS/LVCMOS output, ±50ppm stability, and -40°C to 85°C operating range. Verify that these parameters match your application requirements before substitution.

Q: Why is the WX51500003 obsolete?

A: The WX51500003 has reached end-of-life status. The FD5000050, as an active product in the same manufacturer's SaRonix-eCera™ family, provides continued support and availability for new designs and system updates.

Q: Are there any compliance concerns with substituting the FD5000050?

A: No. The FD5000050 maintains equivalent or enhanced compliance status: ROHS3 Compliant (versus RoHS Compliant), REACH Unaffected, and identical EAR99 export classification. Both components share the same HTSUS code (8542.39.0001).

Q: Will the FD5000050 fit the existing PCB layout?

A: Yes. Both components use the SEAM5032 surface mount package with identical physical dimensions (5.00mm x 3.20mm) and maximum seated height (1.35mm), ensuring direct PCB footprint compatibility without layout redesign.

Q: What is the inventory status of the FD5000050?

A: The FD5000050 is currently in stock with 891 pieces available as new original inventory, ensuring immediate procurement availability.
