Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRT83SL314IB-L is determined by the following critical parameters:

• Functional Equivalence: Both parts must serve as Line Interface Unit (LIU) components within the XRT83 product family
• Interface Compatibility: LIU interface type must be maintained
• Voltage Supply Range: Operating voltage specifications must overlap or be compatible with system requirements (3.135V ~ 3.465V nominal)
• Operating Temperature Range: Must support the full -40°C ~ 85°C operational envelope
• Mounting Technology: Surface Mount configuration must be preserved for PCB assembly compatibility
• Regulatory Classification: ECCN and HTSUS codes must remain consistent for export and tariff purposes

The XRT83VSH316IB-F qualifies as a manufacturer-recommended substitute based on these parameters. While the package configuration differs (316-STBGA 21x21 versus 304-TBGA 31x31), the electrical specifications, functional role, and regulatory classification align with substitution requirements.

Parameter Comparison

Engineering Selection Recommendations

The XRT83VSH316IB-F is designated as the manufacturer-recommended substitute for the obsolete XRT83SL314IB-L. Selection of this alternative is supported by the following factors:

• Product Status Alignment: The substitute is classified as Active, ensuring ongoing availability and manufacturing support from MaxLinear, Inc.
• Electrical Compatibility: Voltage supply ranges (3.135V ~ 3.465V versus 3.14V ~ 3.47V) are compatible, with overlapping operational margins suitable for 3.3V supply systems
• Thermal Specification Match: Both components maintain identical -40°C ~ 85°C operating temperature ranges, preserving thermal design margins
• Regulatory Compliance: Both parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, maintaining export and tariff consistency
• RoHS Compliance: The substitute is RoHS Compliant, meeting modern environmental and regulatory requirements

Design integration requires consideration of package geometry differences: the XRT83VSH316IB-F uses a smaller 316-STBGA (21x21) footprint compared to the original 304-TBGA (31x31), necessitating PCB layout modification. The increased Moisture Sensitivity Level (MSL 4 versus MSL 1) requires adherence to 72-hour dry storage and handling protocols during assembly.

Frequently Asked Questions (FAQ)

Q: Can the XRT83VSH316IB-F directly replace the XRT83SL314IB-L without PCB modification?

A: No. While electrically compatible, the package footprints differ significantly (304-TBGA 31x31 versus 316-STBGA 21x21). PCB layout redesign is required to accommodate the smaller package geometry and ball grid array configuration.

Q: Are the voltage supply specifications compatible between these parts?

A: Yes. The XRT83SL314IB-L operates at 3.135V ~ 3.465V, and the XRT83VSH316IB-F operates at 3.14V ~ 3.47V. Both specifications are compatible with standard 3.3V supply systems, with overlapping operational margins.

Q: What is the significance of the different Moisture Sensitivity Levels?

A: The XRT83SL314IB-L has MSL 1 (Unlimited shelf life), while the XRT83VSH316IB-F has MSL 4 (72-hour dry storage requirement). The substitute requires stricter moisture control during storage and assembly. Components must be baked according to IPC-A-2.3 specifications if moisture absorption occurs.

Q: Do both parts maintain the same regulatory classifications?

A: Yes. Both components share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, ensuring consistent export compliance and tariff treatment.

Q: Is the XRT83VSH316IB-F RoHS compliant?

A: Yes. The substitute is RoHS Compliant, meeting current environmental and regulatory requirements for electronic components in regulated markets.

Q: What is the functional difference between 14 circuits and 16 circuits?

A: The XRT83SL314IB-L provides 14 circuits, while the XRT83VSH316IB-F provides 16 circuits. This difference reflects the enhanced capability of the active substitute. System design must accommodate or utilize the additional circuit capacity.
