Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPC850VR50BU is based on the following critical parameters that must remain constant:

• Core Processor Architecture: MPC8xx series
• Bus Width: 32-Bit
• Operating Frequency: 50MHz
• Package Type: 256-PBGA (23x23)
• I/O Voltage: 3.3V
• Operating Temperature Range: 0°C ~ 95°C (TA)
• Mounting Configuration: Surface Mount
• Compliance Standards: ROHS3 Compliant, REACH Unaffected

The MPC852TVR50A qualifies as a manufacturer-recommended substitute, maintaining identical core specifications, processor architecture, clock speed, package geometry, and electrical characteristics. Both components share the same MPC8xx processor family designation and operate within the same thermal and voltage parameters.

Parameter Comparison

Engineering Selection Recommendations

The MPC852TVR50A is the manufacturer-recommended substitute for the MPC850VR50BU. Both components are classified as obsolete products and maintain full electrical, mechanical, and thermal compatibility.

Selection between these components is determined by packaging availability. The MPC850VR50BU is supplied in standard packaging, while the MPC852TVR50A is supplied in tray packaging. Both components meet ROHS3 compliance requirements and REACH regulatory status. Moisture sensitivity levels are identical at MSL 3 (168 Hours), requiring equivalent handling and storage protocols.

Frequently Asked Questions (FAQ)
