Substitute Part Grouping Explanation

Substitution eligibility for the MPC8248ZQMIBA is determined by strict equivalence across the following critical parameters:

• Processor Core & Architecture: PowerPC G2_LE, 1 Core, 32-Bit configuration
• Clock Frequency: 266MHz operation
• Package Specification: 516-PBGA (27x27) form factor
• I/O Voltage Standard: 3.3V compatibility
• Operating Temperature Range: 0°C ~ 105°C (TA)
• Peripheral Feature Set: Dual Ethernet (10/100Mbps), USB 2.0, security coprocessors, DRAM/SDRAM controllers, and standard serial interfaces (I2C, SPI, UART, USART, SCC, SMC)

The MPC8248VRMIBA qualifies as a direct substitute based on identical electrical specifications, package geometry, and functional feature parity across all listed parameters.

Parameter Comparison

Engineering Selection Recommendations

The MPC8248VRMIBA is the qualified substitute for the obsolete MPC8248ZQMIBA. Both parts maintain identical electrical and functional specifications across all critical parameters: processor architecture, clock frequency, package geometry, voltage standards, temperature range, and peripheral feature integration.

The primary distinction is product lifecycle status: MPC8248ZQMIBA is obsolete with limited availability, while MPC8248VRMIBA is active production with established supply channels. Additionally, MPC8248VRMIBA achieves ROHS3 compliance, whereas MPC8248ZQMIBA is RoHS non-compliant. Both parts carry identical REACH and ECCN classifications.

For new designs or system refresh cycles, MPC8248VRMIBA is the appropriate selection. For legacy system maintenance requiring exact part matching, MPC8248VRMIBA provides functional and electrical equivalence with improved regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Are MPC8248ZQMIBA and MPC8248VRMIBA pin-for-pin compatible?

A: Yes. Both parts use the 516-PBGA (27x27) package with identical pinout, voltage levels (3.3V I/O), and signal definitions. Direct PCB substitution is supported without layout modification.

Q: What is the difference between the two part numbers?

A: The primary differences are product status (obsolete vs. active production) and RoHS compliance (non-compliant vs. ROHS3 compliant). Electrical specifications, processor core, clock speed, and all peripheral features are identical.

Q: Can MPC8248VRMIBA replace MPC8248ZQMIBA in existing systems?

A: Yes. Functional and electrical equivalence is complete across all specified parameters. The substitute part operates within the same temperature range, voltage specifications, and provides identical peripheral integration.

Q: Are there any package or thermal considerations for substitution?

A: No. Both parts use the same 516-PBGA (27x27) package with identical MSL rating (3, 168 Hours). Thermal and mechanical characteristics are equivalent.

Q: What certifications apply to both parts?

A: Both parts share identical REACH (Unaffected) and ECCN (5A002A1 FRE) classifications. MPC8248VRMIBA additionally achieves ROHS3 compliance, providing enhanced regulatory alignment for new applications.
