Substitute Part Grouping Explanation

Substitution for the SL28PCIE06ALCT is based on functional equivalency within the Clock/Timing category, specifically for PCI Express (PCIe) clock generation applications. The identified substitute part SI52208-A01AGMR shares the following critical parameters that establish substitution validity:

• Manufacturer: Skyworks Solutions Inc. (same manufacturer ensures design continuity)
• Category: Clock/Timing (identical functional classification)
• Primary Application: PCI Express (PCIe) clock generation
• Output Type: LVCMOS Clock Generator (compatible output signaling)
• Product Status: Active (ensures ongoing availability and support)

The SI52208-A01AGMR represents an active alternative that maintains functional compatibility for PCIe clock generation while offering improved availability compared to the obsolete SL28PCIE06ALCT.

Parameter Comparison

Engineering Selection Recommendations

Selection between the SL28PCIE06ALCT and SI52208-A01AGMR should be based on product lifecycle requirements and application constraints:

SL28PCIE06ALCT is suitable for legacy system maintenance where existing inventory must be utilized or where design documentation explicitly specifies this part number. The Obsolete status indicates no new production; selection of this part is appropriate only for direct replacement in established applications.

SI52208-A01AGMR is the recommended selection for new designs and ongoing production requirements. As an Active product from the same manufacturer, it provides assured long-term availability, documented electrical specifications (100MHz maximum frequency, 1.5V–1.8V supply voltage, -40°C to 85°C operating range), and compliance classification (EAR99). The MSL rating of 2 (1 Year) requires standard moisture control during storage and handling.

Both parts are manufactured by Skyworks Solutions Inc., ensuring design continuity and support consistency.

Frequently Asked Questions (FAQ)

Q: Can SI52208-A01AGMR directly replace SL28PCIE06ALCT in existing PCB designs?

A: SI52208-A01AGMR is functionally equivalent for PCI Express clock generation applications. However, physical package compatibility must be verified. The SI52208-A01AGMR uses a 48-VFQFN Exposed Pad package; confirm that the original design accommodates this package footprint and pin configuration before implementation.

Q: What is the significance of the MSL rating difference between these parts?

A: SL28PCIE06ALCT carries MSL 1 (Unlimited moisture sensitivity), while SI52208-A01AGMR carries MSL 2 (1 Year). MSL 2 requires that the component be stored in controlled humidity conditions and used within one year of the moisture barrier bag opening date. Standard moisture control procedures are sufficient for typical manufacturing environments.

Q: Why is SL28PCIE06ALCT listed as Obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production and will not resume manufacturing. This classification necessitates transition to active alternatives such as SI52208-A01AGMR for new production and long-term system support.

Q: Are there electrical parameter differences that affect substitution?

A: SI52208-A01AGMR provides documented specifications: 100MHz maximum frequency, 1.5V–1.8V supply voltage range, and -40°C to 85°C operating temperature. The SL28PCIE06ALCT specifications are not provided in this reference. Verify that the documented SI52208-A01AGMR parameters meet your application requirements before substitution.

Q: What compliance certifications apply to these parts?

A: SL28PCIE06ALCT carries ECCN classification as Obsolete. SI52208-A01AGMR carries ECCN EAR99 classification, indicating standard commercial export control treatment.
