Substitute Part Grouping Explanation

Substitution of the PL586-58DC is determined by the following critical parameters:

• Manufacturer Alignment: Microchip Technology maintains product line continuity within its clock buffer portfolio
• Functional Classification: Clock buffer/driver IC category with 1:1 input-to-output ratio
• Signal Compatibility: Crystal input and LVPECL output interface requirements
• Frequency Capability: Maximum operating frequency of 160 MHz or higher
• Supply Voltage Range: 2.97V to 3.63V operating window
• Compliance Standards: ROHS3 compliance and EAR99 export classification

The PL683000XC is identified as the manufacturer-recommended substitute, representing an active product within Microchip's current clock buffer lineup. This part maintains functional equivalence through matching signal interface types and frequency specifications while transitioning from die-level packaging to a 32LQFP surface-mount package format.

Engineering Selection Recommendations

The PL683000XC serves as the manufacturer-recommended equivalent for the obsolete PL586-58DC. Selection of this substitute is supported by:

• Active Product Status: The PL683000XC maintains current production and availability through Microchip Technology, ensuring long-term supply chain continuity
• Regulatory Compliance: Both parts maintain ROHS3 compliance and identical ECCN/HTSUS classifications, eliminating compliance barriers to substitution
• Functional Equivalence: Matching clock buffer/driver classification and signal interface specifications (crystal input, LVPECL output) within the same frequency and voltage operating parameters
• Packaging Transition: Migration from die-level to 32LQFP package format provides improved handling, integration, and manufacturing compatibility for production environments

Frequently Asked Questions (FAQ)

Q: Can the PL683000XC directly replace the PL586-58DC in existing designs?

A: The PL683000XC is functionally equivalent as a clock buffer/driver with matching input/output signal types and frequency specifications. The primary design consideration is the package format transition from die to 32LQFP, which requires PCB layout and assembly process adjustments.

Q: What is the significance of the package change from Die to 32LQFP?

A: Die-level components require specialized handling and integration into hybrid or multi-chip module assemblies. The 32LQFP package provides a standard surface-mount form factor suitable for conventional PCB assembly, improving manufacturability and supply chain accessibility.

Q: Are there compliance or certification differences between these parts?

A: Both parts maintain identical ROHS3 compliance status, EAR99 export classification, and HTSUS coding. No additional compliance verification is required for substitution.

Q: What inventory considerations apply to this substitution?

A: The PL586-58DC is listed as obsolete with 764 pieces in stock. The PL683000XC is an active product with 1003 pieces available, providing improved long-term availability for new production and ongoing support requirements.

Q: Are there moisture sensitivity differences?

A: The PL586-58DC carries MSL 1 (Unlimited) rating, while the PL683000XC carries MSL 3 (168 Hours). Standard moisture control procedures for MSL 3 components during storage and assembly are required.
