Key Parameters

Substitute Part Grouping Explanation

Substitute components for the PL586-15DC are identified based on the following critical parameters that determine functional compatibility:

• Manufacturer: Microchip Technology (same manufacturer ensures design continuity and support)
• Category: Clock/Timing (functional classification)
• Type: Buffer/Driver (core functionality)
• Input/Output Characteristics: Crystal input and LVPECL output capability
• Frequency Range: Support for 125 MHz operation
• Supply Voltage: Compatibility with 2.97V ~ 3.63V range
• RoHS Compliance: ROHS3 Compliant status for regulatory alignment
• Mounting Type: Surface Mount compatibility

The PL583000XC is identified as a manufacturer-recommended substitute. While it operates as a fanout buffer with different packaging (32LQFP vs. die), it maintains the same manufacturer, clock/timing category, and RoHS3 compliance. The substitute part is currently in active production status, addressing the obsolescence of the original component.

Engineering Selection Recommendations

The PL583000XC is the manufacturer-recommended substitute for the obsolete PL586-15DC. Selection of this substitute is supported by the following factors:

• Active Production Status: The PL583000XC is in active production, ensuring long-term availability and supply chain stability compared to the obsolete PL586-15DC.
• Regulatory Compliance: Both components maintain ROHS3 Compliant status and identical ECCN/HTSUS classifications, ensuring no regulatory barriers to substitution.
• Manufacturer Continuity: Both components are manufactured by Microchip Technology, maintaining design support and technical documentation consistency.
• Functional Category: Both components operate within the Clock/Timing category as buffer/driver solutions, confirming functional alignment for clock distribution applications.

Frequently Asked Questions (FAQ)

Q: Can the PL583000XC directly replace the PL586-15DC in existing designs?

A: The PL583000XC is the manufacturer-recommended substitute. However, the package change from die to 32LQFP requires PCB layout modifications. Verify that your application can accommodate the 32LQFP package footprint and that the fanout buffer functionality meets your specific clock distribution requirements.

Q: What is the primary difference between these two components?

A: The PL586-15DC is a 1:1 die-level buffer, while the PL583000XC is a fanout buffer in 32LQFP packaging. The PL586-15DC is obsolete; the PL583000XC is in active production.

Q: Are there any compliance concerns with using the PL583000XC as a substitute?

A: No. Both components are ROHS3 Compliant and share identical ECCN and HTSUS classifications, eliminating regulatory substitution barriers.

Q: What should I verify before implementing the PL583000XC in my design?

A: Confirm that the 32LQFP package is compatible with your PCB layout, verify that the fanout buffer output configuration meets your clock distribution topology, and ensure that the supply voltage range (2.97V ~ 3.63V) aligns with your power delivery system.

Q: Is the PL583000XC available in the same moisture sensitivity level as the PL586-15DC?

A: No. The PL586-15DC has MSL 1 (Unlimited), while the PL583000XC has MSL 3 (168 Hours). This requires stricter moisture control during storage and handling of the substitute component.
