Parameter Comparison

Engineering Selection Recommendations

The PL583000XC serves as the manufacturer-recommended substitute for the obsolete PL586-05DC. Both components maintain identical ROHS3 compliance and EAR99 export classification, ensuring regulatory continuity. The substitute part carries active product status, providing assured long-term availability and manufacturing support.

The transition from die format (PL586-05DC) to 32LQFP package (PL583000XC) represents a packaging evolution within Microchip's clock buffer product line. The substitute maintains equivalent functional classification within the Clock/Timing category and buffer/driver type designation.

Moisture sensitivity level increases from MSL 1 to MSL 3, requiring adherence to appropriate handling and storage protocols during component procurement and assembly operations.

Frequently Asked Questions (FAQ)

Q: Why is the PL586-05DC classified as obsolete? A: The PL586-05DC has reached end-of-life status within Microchip Technology's product portfolio. The PL583000XC represents the active successor within the manufacturer's clock buffer product line.

Q: What is the primary functional difference between the PL586-05DC and PL583000XC? A: The PL586-05DC is a 1:1 clock buffer, while the PL583000XC functions as a fanout buffer. Both operate within the Clock/Timing category and maintain buffer/driver functionality.

Q: Does the package change from die to 32LQFP affect circuit board design? A: Yes. The transition from die format to 32LQFP package requires PCB layout modifications, including footprint redesign, trace routing adjustments, and potential changes to assembly processes. Design validation is necessary prior to production implementation.

Q: Are there supply voltage compatibility concerns? A: The PL586-05DC operates within 2.97V to 3.63V. Verify that the PL583000XC supply voltage specifications align with your system design requirements before implementation.

Q: What handling precautions apply to the PL583000XC? A: The PL583000XC carries MSL 3 rating, requiring storage at controlled humidity levels (≤60% RH) and limiting floor-life exposure to 168 hours after moisture barrier bag opening. Implement appropriate moisture control procedures during component handling and assembly.

Q: Is the PL583000XC the only available substitute? A: The PL583000XC is identified as the manufacturer-recommended substitute. Consult Microchip Technology directly for comprehensive substitute part availability and alternative options within the clock buffer product portfolio.
