Substitute Part Grouping Explanation

Substitute parts for the XR22804IL56-F are determined by strict equivalence across the following critical parameters:

Functional Equivalence: Identical Ethernet bridge function with USB to Ethernet conversion capability
Protocol & Standards: USB 2.0 and 10/100 Base-T/TX PHY support
Electrical Specifications: Matching voltage supply range (4.4V ~ 5.25V) and supply current (185mA)
Thermal Performance: Identical operating temperature range (-40°C ~ 85°C)
Package Compatibility: Same 56-VFQFN Exposed Pad package with 56-QFN (8x8) dimensions
Moisture Sensitivity: Matching MSL rating of 3 (168 Hours)
Regulatory Compliance: RoHS compliance status

The XR22802IL56-F qualifies as a parametric equivalent substitute based on full alignment with all these criteria. Differences in packaging format (Tray vs. standard packaging) and RoHS certification variant (ROHS3 vs. RoHS Compliant) do not affect functional or electrical interchangeability.

Engineering Selection Recommendations

Both the XR22804IL56-F and XR22802IL56-F are active production devices from MaxLinear, Inc., with full RoHS compliance. Selection between these parts should be based on:

Supply Availability: The XR22802IL56-F currently has higher inventory (5,207 units) compared to the XR22804IL56-F (2,150 units), making it suitable for high-volume procurement scenarios.
Packaging Requirements: The XR22802IL56-F is supplied in Tray packaging, while the XR22804IL56-F uses standard packaging. Confirm packaging compatibility with your assembly process and storage requirements.
Regulatory Certification: Both parts meet RoHS requirements. The XR22802IL56-F carries ROHS3 certification, which may be preferred for applications requiring the latest regulatory compliance documentation.
PCB Design: No PCB layout modifications are required when substituting between these parts, as all electrical and mechanical parameters are identical.

Frequently Asked Questions (FAQ)

Q: Can the XR22802IL56-F be used as a direct replacement for the XR22804IL56-F on existing PCBs?

A: Yes. Both parts share identical electrical specifications, package dimensions (56-QFN 8x8), and pin configurations. No PCB redesign or layout modifications are necessary.

Q: Are there differences in USB 2.0 or Ethernet PHY performance between these parts?

A: No. Both parts implement identical USB 2.0 and 10/100 Base-T/TX PHY standards with matching supply current (185mA) and operating temperature ranges (-40°C ~ 85°C).

Q: What is the significance of the packaging format difference (Tray vs. standard)?

A: Packaging format affects handling, storage, and assembly logistics but does not impact electrical or functional performance. Confirm your assembly equipment and storage procedures are compatible with Tray packaging if selecting the XR22802IL56-F.

Q: Do both parts meet the same moisture sensitivity requirements?

A: Yes. Both parts have an MSL rating of 3 (168 Hours), requiring identical storage and handling protocols to prevent moisture absorption.

Q: Is the ROHS3 certification of the XR22802IL56-F a functional improvement over RoHS Compliant status?

A: No. ROHS3 represents a more recent regulatory certification standard but does not alter the device's electrical performance or functionality. Selection should be based on your application's regulatory requirements.

Q: What is the base product number relationship between XR22804 and XR22802?

A: These are distinct base product numbers from MaxLinear, Inc. The suffix IL56-F indicates the specific package variant (56-QFN with exposed pad). Both base products are qualified as parametric equivalents for Ethernet bridge applications.
