Substitute Part Grouping Explanation

Substitution of the PL586-25DC is determined by the following critical parameters:

• Manufacturer: Microchip Technology (primary source for compatible timing solutions)
• Category: Clock/Timing integrated circuits
• Functional Type: Buffer/Driver with crystal input capability
• Output Standard: LVPECL compatibility
• Frequency Range: Maximum 125 MHz operation
• Supply Voltage: 2.97V to 3.63V compatibility
• Packaging: Die-level or equivalent surface-mount form factor
• Compliance: ROHS3 certification requirement

The substitute part PL583000XC is classified as a fanout buffer within the same Microchip Technology product family, maintaining category alignment and compliance standards. While the substitute exhibits different circuit count and packaging characteristics, it operates within the same voltage and frequency parameters necessary for clock distribution applications.

Parameter Comparison

Engineering Selection Recommendations

The PL583000XC serves as an active substitute for the obsolete PL586-25DC within Microchip Technology's clock/timing product portfolio. Both components maintain ROHS3 compliance and identical export classification (EAR99), ensuring regulatory consistency. The substitute transitions from die-level packaging to a 32LQFP surface-mount package, requiring circuit board redesign considerations. The substitute's active product status ensures ongoing availability and technical support from the manufacturer, addressing the obsolescence constraint of the original part. Moisture sensitivity classification increases from MSL 1 to MSL 3, necessitating updated handling and storage protocols during manufacturing and assembly operations.

Frequently Asked Questions (FAQ)

Q: Can PL583000XC directly replace PL586-25DC without circuit modifications?

A: Package form factor differs significantly. The original part is supplied as a die, while the substitute is a 32LQFP packaged component. Circuit board layout and interconnection topology require redesign to accommodate the different package type.

Q: Are both parts compliant with the same regulatory standards?

A: Yes. Both PL586-25DC and PL583000XC carry ROHS3 compliance certification and share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: What is the impact of the MSL rating change from 1 to 3?

A: MSL 1 allows unlimited shelf life under controlled conditions, while MSL 3 restricts storage to 168 hours at specified temperature and humidity levels. Manufacturing and assembly processes must implement moisture control measures, including baking procedures prior to reflow soldering.

Q: Are both parts manufactured by the same company?

A: Yes. Both components are manufactured by Microchip Technology, ensuring design philosophy and technical support consistency.

Q: What is the primary functional difference between these parts?

A: The PL586-25DC is a 1:1 buffer/driver, while the PL583000XC is a fanout buffer. The substitute provides expanded output distribution capability within the same clock/timing category.
