PL586-08DC Equivalent & Substitute Parts

Part Overview

The PL586-08DC is a Clock Buffer/Driver IC manufactured by Microchip Technology, designed as a 1:1 clock buffer with 200 MHz maximum frequency capability. This die-format component accepts crystal input and outputs LVPECL signals, operating within a 2.97V to 3.63V supply voltage range. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PL586-08DC is determined by the following critical parameters:

• Manufacturer: Microchip Technology (same manufacturer ensures design compatibility and support continuity)
• Category: Clock/Timing (functional classification)
• Type: Buffer/Driver (core functionality)
• Input/Output Characteristics: Crystal input and LVPECL output capability
• Frequency Range: Maximum 200 MHz operation
• Supply Voltage: 2.97V to 3.63V compatibility
• RoHS Compliance: ROHS3 Compliant status for regulatory alignment

The PL583000XC is identified as the manufacturer-recommended substitute. While it functions as a fanout buffer with expanded circuit capability (32LQFP package versus die format), it maintains core clock/timing functionality within the Microchip Technology product line and operates under equivalent regulatory compliance standards.

Engineering Selection Recommendations

The PL583000XC is the manufacturer-recommended substitute for the obsolete PL586-08DC. Selection of this substitute is supported by:

• Active Product Status: The PL583000XC maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete PL586-08DC.
• Regulatory Compliance: Both components maintain ROHS3 Compliant certification and identical ECCN/HTSUS classifications, ensuring equivalent regulatory standing.
• Manufacturer Continuity: Both components are manufactured by Microchip Technology, providing design support and technical documentation consistency.
• Functional Category: Both components operate within the Clock/Timing category as buffer/driver solutions, maintaining functional equivalence within system applications.

The transition from die format (PL586-08DC) to 32LQFP package (PL583000XC) represents a packaging evolution typical of component obsolescence cycles, with the packaged solution offering improved handling and integration characteristics for production environments.

Frequently Asked Questions (FAQ)

Q: Why is the PL586-08DC classified as obsolete?

A: The PL586-08DC is listed as obsolete by Microchip Technology. The PL583000XC represents the active product line continuation for clock buffer/driver functionality within the manufacturer's portfolio.

Q: What is the primary difference between the PL586-08DC and PL583000XC?

A: The main difference is packaging format. The PL586-08DC is supplied as a die, while the PL583000XC is packaged in 32LQFP format. The PL583000XC also functions as a fanout buffer, providing expanded circuit capability compared to the 1:1 buffer configuration of the PL586-08DC.

Q: Are both components RoHS compliant?

A: Yes, both the PL586-08DC and PL583000XC maintain ROHS3 Compliant status, meeting equivalent environmental and regulatory requirements.

Q: What is the difference in Moisture Sensitivity Level (MSL) between these components?

A: The PL586-08DC has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The PL583000XC has MSL 3 (168 Hours), requiring controlled moisture exposure during storage and handling. This difference reflects typical packaging format variations, with die components generally having lower MSL ratings than packaged components.

Q: Can the PL583000XC be used as a direct replacement in all applications?

A: The PL583000XC is the manufacturer-recommended substitute. However, application-specific requirements such as frequency range, supply voltage compatibility, and circuit configuration must be verified against your system design specifications. The fanout buffer capability of the PL583000XC may provide additional functionality beyond the 1:1 buffer configuration of the original component.

Q: What is the inventory status of these components?

A: The PL586-08DC has 744 pieces available as new original stock. The PL583000XC has 1157 pieces available as new original stock, providing greater availability for new designs and production requirements.
