KMPC8347ECVRAGDB Equivalent & Substitute Parts

Part Overview

The KMPC8347ECVRAGDB is a PowerPC e300 microprocessor IC from the MPC83xx series manufactured by NXP USA Inc. This embedded processor operates at 266MHz with a single 32-bit core and integrates dual Gigabit Ethernet ports, dual USB 2.0 interfaces, and security co-processors. The device is housed in a 620-HBGA (29x29) package with exposed pad and operates across the industrial temperature range of -40°C to 105°C.

The KMPC8347ECVRAGDB is classified as obsolete. Identifying equivalent and substitute parts is necessary to support legacy system maintenance, design updates, and supply chain continuity when original inventory becomes unavailable.

Substitute Part Grouping Explanation

Substitution eligibility for the KMPC8347ECVRAGDB is determined by the following critical parameters:

Core processor architecture (PowerPC e300)
Package type and pin configuration (620-HBGA 29x29)
I/O voltage compatibility (2.5V, 3.3V)
Operating temperature range (-40°C ~ 105°C)
Interface set (Ethernet, USB, DUART, I2C, PCI, SPI)
Security co-processor availability
RoHS and environmental compliance status

The MPC8347ECVRAGDB qualifies as a direct substitute. While this part operates at 400MHz compared to the 266MHz of the main part, it maintains identical core architecture, package footprint, voltage specifications, interface configuration, and compliance certifications. The higher operating frequency does not preclude substitution in applications designed for the KMPC8347ECVRAGDB, as the substitute operates within the same electrical and thermal envelope.

Engineering Selection Recommendations

The MPC8347ECVRAGDB is suitable for direct substitution of the KMPC8347ECVRAGDB based on the following factors:

Both parts maintain identical pin configuration and package footprint (620-HBGA 29x29), ensuring mechanical and electrical compatibility without PCB redesign.
Voltage specifications and I/O characteristics are identical, eliminating the need for power supply or signal conditioning modifications.
The complete interface set—including dual Gigabit Ethernet, dual USB 2.0, DUART, I2C, PCI, and SPI—is preserved across both parts.
Security co-processor functionality (cryptography and random number generator) is maintained.
Both parts comply with ROHS3 and maintain identical moisture sensitivity levels.
The substitute part carries Active product status, ensuring continued availability and support from the manufacturer.

The higher operating frequency of the MPC8347ECVRAGDB (400MHz versus 266MHz) represents a performance enhancement that does not introduce compatibility issues in applications designed for the original part.

Frequently Asked Questions (FAQ)

Q: Can the MPC8347ECVRAGDB be used as a direct replacement for the KMPC8347ECVRAGDB without PCB modifications?

A: Yes. Both parts use the identical 620-HBGA (29x29) package with exposed pad. Pin configuration, spacing, and footprint are identical, eliminating the need for PCB redesign or layout changes.

Q: What is the primary difference between these two parts?

A: The operating frequency differs: the KMPC8347ECVRAGDB operates at 266MHz, while the MPC8347ECVRAGDB operates at 400MHz. All other electrical, mechanical, and functional parameters are identical.

Q: Are the voltage requirements the same?

A: Yes. Both parts operate with identical I/O voltage specifications of 2.5V and 3.3V and maintain the same operating temperature range of -40°C to 105°C.

Q: Do both parts support the same interfaces?

A: Yes. Both parts include dual 10/100/1000Mbps Ethernet ports, dual USB 2.0 interfaces with PHY, DUART, I2C, PCI, and SPI interfaces. Security co-processors with cryptography and random number generator functions are present in both.

Q: What is the product status difference?

A: The KMPC8347ECVRAGDB is classified as obsolete, while the MPC8347ECVRAGDB is active. This makes the substitute part the recommended choice for new designs and ongoing supply requirements.
