Key Parameters

Substitute Part Grouping Explanation

Substitution of the PL686-05DC is determined by the following critical parameters:

• Manufacturer: Microchip Technology (maintained for design continuity and supply chain consistency)
• Category: Clock/Timing (functional classification)
• Type: Buffer/Driver (circuit topology)
• Ratio - Input:Output: 1:1 (signal distribution architecture)
• Frequency - Max: 170 MHz (operational bandwidth requirement)
• Output Type: LVPECL (signal standard compatibility)
• Voltage - Supply: 2.97V ~ 3.63V (power supply compatibility)
• RoHS Status: ROHS3 Compliant (regulatory compliance)

The substitute part PL683000XC is identified as the manufacturer-recommended alternative, maintaining functional equivalence within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

The PL683000XC is designated as the manufacturer-recommended substitute for the obsolete PL686-05DC. Both components are manufactured by Microchip Technology and maintain ROHS3 compliance. The substitute part is currently in active production status, ensuring long-term availability and supply chain stability.

The primary distinction between the main part and substitute is the package configuration: the PL686-05DC is supplied as a die, while the PL683000XC is packaged in 32LQFP format. This packaging difference requires evaluation within the context of the end-application assembly process and PCB layout requirements.

The substitute part carries a higher Moisture Sensitivity Level (MSL 3 versus MSL 1), which impacts handling and storage protocols during manufacturing operations.

Frequently Asked Questions (FAQ)

Q: Can PL683000XC directly replace PL686-05DC in all applications?

A: Both parts are Microchip Technology clock buffer/driver ICs within the same product category. The manufacturer designates PL683000XC as the recommended substitute. However, the packaging difference (die versus 32LQFP) requires assessment of assembly compatibility and PCB integration requirements specific to your application.

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

A: The PL686-05DC die format is used in hybrid or custom packaging applications, while the PL683000XC 32LQFP package is a standard surface-mount integrated circuit package. This change affects assembly methodology, PCB layout, and thermal management considerations.

Q: How does the Moisture Sensitivity Level difference impact component handling?

A: The PL686-05DC (MSL 1) has unlimited shelf life under standard conditions. The PL683000XC (MSL 3) requires controlled moisture exposure with a 168-hour floor life after moisture barrier bag opening. This affects storage, handling procedures, and manufacturing scheduling.

Q: Are both parts ROHS3 compliant?

A: Yes, both the PL686-05DC and PL683000XC are ROHS3 compliant, maintaining regulatory alignment for applications subject to RoHS directives.

Q: What is the current availability status of these parts?

A: The PL686-05DC is obsolete with existing inventory of 965 pieces. The PL683000XC is in active production status with 1003 pieces currently in stock, providing ongoing supply assurance.
