Key Parameters

Substitute Part Grouping Explanation

Substitution for the PL585-28DC is based on the following critical parameters:

• Manufacturer: Microchip Technology (maintained for design continuity and support)
• Category: Clock/Timing (functional equivalence)
• Frequency Range: 250MHz maximum operating frequency
• Input/Output Characteristics: Crystal input with LVPECL output
• Supply Voltage: 2.97V ~ 3.63V compatibility
• RoHS Compliance: ROHS3 Compliant status
• Product Status: Active alternatives to obsolete component

The substitute part PL583000XC is a fanout buffer in 32LQFP package format, representing a functional alternative from the same manufacturer within the clock/timing category. This part maintains Microchip Technology sourcing and ROHS3 compliance, though package format differs from the original die configuration.

Parameter Comparison

Engineering Selection Recommendations

Selection between the PL585-28DC and PL583000XC must account for the following factors:

Product Status: The PL585-28DC is obsolete. The PL583000XC is active and currently manufactured, ensuring long-term availability and supply chain continuity.

Compliance: Both parts maintain ROHS3 compliance and EAR99 export classification, satisfying regulatory requirements for equivalent applications.

Package Consideration: The original part is supplied as a die, while the substitute is packaged in 32LQFP format. This represents a significant physical and integration difference requiring board-level design modifications.

Moisture Sensitivity: The substitute part has MSL rating of 3 (168 hours), compared to MSL 1 (unlimited) for the original. This affects storage and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can PL583000XC directly replace PL585-28DC in existing designs?

A: Direct replacement is not possible due to package format differences. The original die format requires integration into a specific substrate or package, while the substitute is a finished 32LQFP component. Board redesign is necessary.

Q: Are both parts from the same manufacturer?

A: Yes, both PL585-28DC and PL583000XC are manufactured by Microchip Technology, ensuring consistent design philosophy and support.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and classified under ECCN EAR99, with matching HTSUS codes (8542.39.0001).

Q: How does moisture sensitivity differ between these parts?

A: The PL585-28DC has MSL 1 (unlimited shelf life), while PL583000XC has MSL 3 (168-hour maximum exposure). The substitute requires more controlled storage conditions.

Q: What is the functional category for both parts?

A: Both parts are classified as Clock/Timing components within the Microchip Technology product portfolio.
