Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KMPC8358CVRAGDDA is determined by the following critical parameters:

• Processor Architecture: PowerPC e300 core with 32-bit bus width
• Performance: 400MHz clock speed
• Integrated Peripherals: QUICC Engine, DDR/DDR2 memory controllers, Gigabit Ethernet, USB 1.x
• Interface Protocols: DUART, HDLC, I2C, PCI, SPI, UART support
• Package Compatibility: 668-PBGA-PGE (29x29) ball grid array form factor
• Electrical Specifications: I/O voltage levels (1.8V, 2.5V, 3.3V) and operating temperature range (-40°C to 105°C)
• Regulatory Compliance: RoHS3 compliance and REACH status

The substitute part MPC8358CVRAGDDA maintains functional equivalence through identical processor core architecture, clock speed, integrated communications engine, memory controller support, and peripheral interface set. Both parts operate within the same electrical and thermal specifications and share the same package footprint.

Parameter Comparison

Engineering Selection Recommendations

The MPC8358CVRAGDDA from Freescale Semiconductor is a direct functional equivalent to the obsolete KMPC8358CVRAGDDA. Both parts share identical processor architecture, clock frequency, integrated peripheral set, and package specifications. The substitute part maintains full RoHS3 compliance and REACH compliance status, ensuring regulatory alignment with the original design.

The primary distinction is product status: the original part is obsolete while the substitute remains active, providing supply chain availability. The substitute part carries a higher Moisture Sensitivity Level (MSL 3 versus MSL 1), requiring adherence to 168-hour moisture exposure limits during storage and handling. This difference necessitates implementation of appropriate moisture control procedures during component procurement, storage, and assembly operations.

Both parts are suitable for direct pin-for-pin replacement in existing PCB designs without circuit modification, provided that moisture handling protocols are observed for the substitute part.

Frequently Asked Questions (FAQ)

Q: Can MPC8358CVRAGDDA directly replace KMPC8358CVRAGDDA in existing designs?

A: Yes. Both parts feature identical PowerPC e300 core architecture, 400MHz clock speed, 32-bit bus width, QUICC Engine integration, DDR/DDR2 memory controller support, and 668-PBGA-PGE (29x29) package footprint. Pin-for-pin replacement is supported without circuit redesign.

Q: What is the significance of the different Moisture Sensitivity Levels?

A: The original part (MSL 1) has unlimited moisture exposure tolerance, while the substitute (MSL 3) is limited to 168 hours of exposure above 30% relative humidity. Organizations must implement moisture control procedures including dry storage, desiccant packaging, and bake-out procedures prior to assembly to maintain component reliability.

Q: Are there differences in electrical specifications between the two parts?

A: No. Both parts operate at identical I/O voltage levels (1.8V, 2.5V, 3.3V) and the same operating temperature range (-40°C to 105°C). Electrical performance and thermal characteristics are equivalent.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the original and substitute parts are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: What is the primary reason to select the substitute part?

A: The original KMPC8358CVRAGDDA is classified as obsolete, creating supply chain risk. The MPC8358CVRAGDDA substitute maintains active product status, ensuring component availability for new production runs and legacy system support.
