Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XRT83SL216IB-F is determined by the following critical parameters:

• Base Product Series: XRT83 (common base designation)
• Function: Line Interface Unit (LIU) with 16-circuit configuration
• Interface Type: LIU
• Supply Voltage Range: Compatible with 3.1V to 4.6V nominal operation
• Operating Temperature Range: -40°C to 85°C
• Mounting Technology: Surface Mount
• Moisture Sensitivity Level: MSL 4 (72 Hours)
• Regulatory Classification: EAR99 / HTSUS 8542.39.0001

The XRT83VSH316IB-F qualifies as a substitute based on matching the XRT83 base product family, identical functional specification (16-circuit LIU), overlapping supply voltage parameters, identical operating temperature range, and equivalent moisture sensitivity classification. The primary distinction is the package form factor: 316-STBGA (21x21) versus 289-STBGA (15x15).

Parameter Comparison

Engineering Selection Recommendations

The XRT83VSH316IB-F is the designated manufacturer substitute for the obsolete XRT83SL216IB-F. Both components share identical functional specifications, electrical operating parameters, and regulatory classifications. The substitute maintains Active product status, ensuring ongoing availability and supply chain continuity.

The primary design consideration is the package footprint transition from 289-STBGA (15x15mm) to 316-STBGA (21x21mm). This larger package format requires PCB layout modification to accommodate the increased die size. Supply voltage specifications remain compatible within the specified operating ranges. Thermal and environmental operating conditions are identical.

Both components carry RoHS compliance status and equivalent moisture sensitivity ratings, supporting deployment in standard manufacturing environments with MSL 4 handling protocols.

Frequently Asked Questions (FAQ)

Q: Can the XRT83VSH316IB-F directly replace the XRT83SL216IB-F without design changes?

A: Functional and electrical compatibility is confirmed. However, the package footprint differs: 289-STBGA (15x15mm) versus 316-STBGA (21x21mm). PCB layout and land pattern modifications are required.

Q: Are the supply voltage specifications compatible?

A: Yes. The XRT83SL216IB-F operates at 3.135V ~ 3.465V, while the XRT83VSH316IB-F operates at 3.14V ~ 3.47V. These ranges overlap sufficiently for standard 3.3V supply applications.

Q: What is the significance of the product status change from Obsolete to Active?

A: The substitute part maintains Active status, indicating current manufacturing and availability. This ensures long-term supply chain support and eliminates obsolescence risk associated with the original component.

Q: Are moisture sensitivity requirements identical?

A: Yes. Both components carry MSL 4 (72 Hours) classification, requiring identical handling and storage protocols during manufacturing and assembly.

Q: Do both parts share the same regulatory classifications?

A: Yes. Both components are classified as EAR99 and HTSUS 8542.39.0001, maintaining identical export control and tariff status.
