Substitute Part Grouping Explanation

Substitute parts for the R7F701A303AFP#KA2 are identified based on the following critical parameters that determine functional and physical compatibility:

Core Compatibility Criteria:

• Identical base product number (R7F701A303) ensuring core microcontroller architecture and instruction set compatibility
• Matching manufacturer (Renesas Electronics Corporation) for consistent design integration and support
• Identical category classification (Embedded) and component type (Microcontroller IC)
• Matching bit width specification (32-bit)
• Equivalent or superior RoHS compliance status (ROHS3 Compliant)
• Matching or equivalent Moisture Sensitivity Level (MSL 3)
• Identical REACH compliance status (REACH Unaffected)

The primary distinction between the main part and substitute relates to packaging configuration and product lifecycle status. Substitute parts maintain electrical and functional equivalence while offering active product status and improved procurement availability.

Parameter Comparison

Engineering Selection Recommendations

For Obsolescence Mitigation: The R7F701A303AFP-C#KA2 serves as the active equivalent to the obsolete R7F701A303AFP#KA2. Both components share identical base product architecture, electrical specifications, and compliance certifications. The substitute part maintains ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original design.

For New Designs: The R7F701A303AFP-C#KA2 is the appropriate selection for new development efforts, as it maintains active product status with Renesas Electronics Corporation and demonstrates superior procurement availability (1087 units in stock versus 931 units for the obsolete variant).

For Existing Inventory Management: Current stock of the R7F701A303AFP#KA2 remains available for immediate deployment. Transition planning to the active substitute should be coordinated with production schedules to optimize inventory utilization while ensuring long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Are the R7F701A303AFP#KA2 and R7F701A303AFP-C#KA2 electrically equivalent?

A: Yes. Both components share the identical base product number (R7F701A303) and are manufactured by Renesas Electronics Corporation. They maintain matching 32-bit microcontroller architecture, RoHS3 compliance, MSL 3 rating, and REACH unaffected status.

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

A: The primary difference is packaging configuration. The R7F701A303AFP#KA2 uses LFQFP packaging, while the R7F701A303AFP-C#KA2 uses 144-LQFP packaging. Additionally, the substitute part maintains active product status, whereas the main part is classified as obsolete.

Q: Can I use the R7F701A303AFP-C#KA2 as a direct replacement in existing PCB designs?

A: Packaging compatibility must be verified against your PCB layout and footprint specifications. While both components are electrically equivalent, the different package types (LFQFP versus 144-LQFP) require confirmation of physical fit and pin compatibility with your existing design.

Q: What is the Moisture Sensitivity Level (MSL) for these components?

A: Both the R7F701A303AFP#KA2 and R7F701A303AFP-C#KA2 carry an MSL rating of 3 with a 168-hour floor life. This specification governs handling, storage, and reflow soldering procedures during assembly operations.

Q: Are both parts RoHS compliant?

A: Yes. Both the R7F701A303AFP#KA2 and R7F701A303AFP-C#KA2 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Why is the main part listed as obsolete?

A: Product obsolescence is determined by the manufacturer based on lifecycle management and market demand. The active substitute part (R7F701A303AFP-C#KA2) provides continuity for designs requiring this microcontroller architecture while ensuring ongoing manufacturer support and supply availability.
