Key Parameters

Substitute Part Grouping Explanation

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

• Manufacturer Consistency: Both parts are manufactured by MaxLinear, Inc., ensuring design compatibility and support continuity
• Functional Equivalence: Both components serve as Line Interface Units (LIU) with identical interface classification
• Voltage Supply Compatibility: Operating voltage ranges are overlapping (3.135V ~ 3.465V for XRT83SL314IB; 3.14V ~ 3.47V for XRT83VSH316IB-F), permitting direct substitution in power delivery circuits
• Temperature Operating Range: Identical temperature specifications (-40°C ~ 85°C) ensure thermal compatibility
• Surface Mount Technology: Both components use surface mount packaging, maintaining PCB assembly process compatibility
• Base Product Series: Both parts share the XRT83 base product number, indicating common design lineage and functional architecture

The XRT83VSH316IB-F represents the active equivalent with enhanced circuit count (16 circuits versus 14) and improved package density (316-STBGA 21x21 versus 304-TBGA 31x31).

Parameter Comparison

Engineering Selection Recommendations

The XRT83VSH316IB-F is the manufacturer-recommended substitute for the obsolete XRT83SL314IB. Selection of this part is justified by:

• Active Product Status: The XRT83VSH316IB-F maintains active manufacturing and support status, ensuring long-term availability and supply chain continuity
• RoHS Compliance: The substitute part meets RoHS compliance requirements, supporting regulatory requirements for new designs and system updates
• Functional Compatibility: Identical LIU interface architecture and overlapping voltage specifications enable direct functional substitution
• Enhanced Circuit Density: The increased circuit count (16 versus 14) and reduced package footprint (21x21 versus 31x31) provide design flexibility for space-constrained applications

Frequently Asked Questions (FAQ)

Q: Can the XRT83VSH316IB-F directly replace the XRT83SL314IB in existing designs?

A: Direct replacement is functionally supported due to identical interface type, overlapping voltage ranges, and matching temperature specifications. PCB layout modifications are required due to different package dimensions (304-TBGA 31x31 versus 316-STBGA 21x21).

Q: What is the significance of the different circuit counts (14 versus 16)?

A: The XRT83VSH316IB-F provides two additional circuits within a smaller package footprint. System designs must verify that all 16 circuits are utilized or that unused circuits are properly terminated according to MaxLinear design guidelines.

Q: How does the Moisture Sensitivity Level difference affect handling?

A: The XRT83SL314IB (MSL 1) has unlimited shelf life under standard conditions. The XRT83VSH316IB-F (MSL 4) requires controlled storage and has a 72-hour floor life after moisture exposure. Standard ESD and moisture control procedures apply during assembly.

Q: Are there compatibility concerns with the package change from 304-TBGA to 316-STBGA?

A: Both packages use identical ball grid array technology and surface mount assembly processes. The primary difference is physical footprint and ball count. PCB redesign is necessary to accommodate the new package geometry.

Q: What certifications apply to the substitute part?

A: The XRT83VSH316IB-F carries RoHS compliance certification and maintains the same ECCN (EAR99) and HTSUS (8542.39.0001) classifications as the original part.
