Substitute Part Grouping Explanation

Substitution eligibility for the KMPC8343EVRAGDB is determined by strict equivalence across the following critical parameters:

Core Architecture: PowerPC e300 single-core 32-bit processor at 400MHz Memory Support: DDR and DDR2 RAM controllers Networking: Triple Gigabit Ethernet (10/100/1000Mbps) Peripheral Interfaces: USB 2.0 with PHY (2 ports), DUART, I2C, PCI, SPI Security Co-Processor: Cryptography and Random Number Generator Electrical Specifications: I/O voltage support (1.8V, 2.5V, 3.3V), operating temperature range (0°C ~ 105°C) Package Specification: 620-HBGA (29x29) with exposed pad Compliance: ROHS3 Compliant, REACH Unaffected

The substitute part MPC8343EVRAGDB maintains identical electrical, functional, and mechanical specifications while offering active product status and improved inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The MPC8343EVRAGDB serves as a direct functional equivalent to the KMPC8343EVRAGDB. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The primary distinction is product status: the main part is classified as obsolete while the substitute maintains active status with significantly higher inventory availability (2055 units versus 795 units).

For new designs, procurement of legacy systems, or component replacement in existing applications, the MPC8343EVRAGDB is the appropriate selection. The identical electrical specifications, core architecture, peripheral integration, security features, and package footprint ensure direct compatibility without design modification or functional compromise.

Frequently Asked Questions (FAQ)

Q: Are KMPC8343EVRAGDB and MPC8343EVRAGDB pin-compatible? A: Yes. Both parts use the 620-HBGA (29x29) package with exposed pad configuration. Pin assignments, signal definitions, and mechanical footprint are identical.

Q: Can MPC8343EVRAGDB replace KMPC8343EVRAGDB in existing PCB assemblies? A: Yes. The substitute part maintains identical electrical characteristics, operating temperature range, voltage specifications, and interface protocols. No PCB redesign or firmware modification is required.

Q: What is the difference between the two part numbers? A: The part numbers differ only in the prefix (K versus no prefix). Both designate the same MPC83xx series processor with identical core specifications. The difference reflects manufacturer designation changes; the substitute represents the current active part number.

Q: Are the security features identical between both parts? A: Yes. Both parts include cryptography and random number generator co-processors with identical functional capabilities.

Q: What is the significance of the 620-HBGA package designation? A: The 620-HBGA (29x29) is a high-density ball grid array package with 620 solder balls. This package type is required for the thermal and electrical performance of the MPC83xx processor. Both parts use this identical package specification.

Q: Are there any compliance or certification differences? A: No. Both parts are ROHS3 compliant with MSL 3 (168 hours) moisture sensitivity rating and REACH unaffected status.
