MPC8313VRAFFB Equivalent & Substitute Parts

Part Overview

The MPC8313VRAFFB is a PowerPC e300c3 microprocessor IC from the MPC83xx series, featuring a single 32-bit core operating at 333MHz. This embedded processor integrates dual Gigabit Ethernet controllers, DDR/DDR2 memory support, USB 2.0 with PHY, and multiple serial interfaces including DUART, HSSI, I2C, PCI, and SPI. The device is housed in a 516-TEPBGA (27x27) package with exposed pad and operates across the industrial temperature range of 0°C to 105°C.

The MPC8313VRAFFB is classified as obsolete. Locating equivalent or substitute components becomes necessary when original stock is depleted or when design flexibility permits component selection from active product lines. The MPC8313VRAFFC serves as the primary substitute, maintaining identical electrical and mechanical specifications while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPC8313VRAFFB is determined by strict equivalence across the following critical parameters:

Core Architecture & Performance: The substitute must employ the identical PowerPC e300c3 core, maintain single-core configuration, preserve 32-bit bus width, and operate at 333MHz clock speed.

Memory & Interface Support: The substitute must support DDR and DDR2 memory controllers, provide dual Gigabit Ethernet (10/100/1000Mbps), include USB 2.0 with integrated PHY, and maintain all serial interfaces (DUART, HSSI, I2C, PCI, SPI).

Electrical Specifications: The substitute must support identical I/O voltage levels (1.8V, 2.5V, 3.3V) and operate within the same temperature range (0°C to 105°C).

Physical & Environmental Compliance: The substitute must use the 516-TEPBGA (27x27) package with exposed pad, maintain surface mount mounting type, comply with ROHS3 standards, and match MSL rating of 3 (168 Hours).

The MPC8313VRAFFC meets all substitution criteria, with the primary distinction being product status (Active vs. Obsolete) and packaging format (Tray vs. unspecified for the main part).

Parameter Comparison

Engineering Selection Recommendations

The MPC8313VRAFFC is a direct functional equivalent to the MPC8313VRAFFB. Both devices are manufactured by NXP USA Inc. and share identical electrical, mechanical, and interface specifications. The MPC8313VRAFFC maintains ROHS3 compliance and identical MSL rating, ensuring compatibility with existing environmental and regulatory requirements.

The primary distinction is product lifecycle status: the MPC8313VRAFFB is classified as obsolete, while the MPC8313VRAFFC maintains active product status. This status difference reflects manufacturing availability and long-term supply chain considerations rather than technical capability differences.

Selection of the MPC8313VRAFFC is appropriate for new designs, production restocking, or replacement scenarios where component availability is a consideration. Both parts are suitable for applications requiring PowerPC e300c3 architecture with integrated Gigabit Ethernet, DDR memory support, and embedded serial interfaces within the specified temperature and voltage operating ranges.

Frequently Asked Questions (FAQ)

Q: Are the MPC8313VRAFFB and MPC8313VRAFFC pin-compatible?

A: Yes. Both devices use the 516-TEPBGA (27x27) package with exposed pad. Pin assignments, signal definitions, and electrical characteristics are identical, enabling direct substitution at the PCB level.

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

A: The MPC8313VRAFFB and MPC8313VRAFFC are functionally equivalent. The difference in the final characters (FB vs. FC) reflects packaging or distribution channel designation. The MPC8313VRAFFC is the active product offering from NXP USA Inc., while the MPC8313VRAFFB is classified as obsolete.

Q: Can I use the MPC8313VRAFFC as a drop-in replacement for the MPC8313VRAFFB?

A: Yes. All electrical specifications, interface configurations, operating temperature ranges, voltage requirements, and package dimensions are identical. No circuit modifications or firmware changes are required for substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both the MPC8313VRAFFB and MPC8313VRAFFC are ROHS3 compliant and carry identical Moisture Sensitivity Level (MSL) ratings of 3 (168 Hours).

Q: Which part should I specify for new designs?

A: The MPC8313VRAFFC should be specified for new designs due to its active product status, ensuring long-term availability and manufacturing support from NXP USA Inc.

Q: Are there any differences in memory controller support?

A: No. Both parts support identical DDR and DDR2 memory controllers with no functional or performance differences.

Q: Do both parts support the same Ethernet and USB configurations?

A: Yes. Both devices integrate dual Gigabit Ethernet controllers (10/100/1000Mbps) and single USB 2.0 with integrated PHY. Serial interface support (DUART, HSSI, I2C, PCI, SPI) is identical across both parts.
