Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XRT75R12IB is determined by the following critical parameters:

• Manufacturer and Base Product: Parts must originate from MaxLinear, Inc., and share the XRT75 base product number to ensure functional compatibility
• Function and Interface Type: The component must perform Line Interface Unit (LIU) functionality with identical interface specifications
• Circuit Count: 12 circuits must be maintained
• Voltage Supply Range: 3.135V ~ 3.465V compatibility is required
• Operating Temperature Range: -40°C ~ 85°C specification must be met
• Package and Mounting: 420-LBGA package with 420-TBGA (35x35) supplier device package and surface mount configuration must be identical
• Moisture Sensitivity: MSL 4 (72 Hours) rating must be maintained

The XRT75R12IB-L meets all substitution criteria and is classified as a direct manufacturer equivalent.

Parameter Comparison

Engineering Selection Recommendations

The XRT75R12IB-L is the direct substitute for the XRT75R12IB. Both components share identical electrical and mechanical specifications, including voltage supply range, operating temperature range, circuit count, and package configuration.

The primary distinction is product status: the XRT75R12IB is obsolete, while the XRT75R12IB-L is active. The XRT75R12IB-L is RoHS Compliant, providing additional regulatory compliance for new designs and long-term availability assurance.

For applications currently using the XRT75R12IB, transition to the XRT75R12IB-L is supported by full parameter equivalence and identical package specifications.
