Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the R7F701331AEAFP#KA2 is determined by the following critical parameters:

Manufacturer Alignment: Both the main part and substitute must originate from Renesas Electronics Corporation to ensure design compatibility and firmware consistency.

Base Product Number: The substitute part must share the identical base product number R7F701331, confirming functional equivalence at the core microcontroller level.

Regulatory Compliance: Both parts must maintain ROHS3 compliance and REACH Unaffected status to satisfy environmental and regulatory requirements.

Moisture Sensitivity Level: Both parts must maintain MSL 3 (168 Hours) classification to ensure identical handling, storage, and assembly process requirements.

Category Classification: Both parts must remain classified as Embedded microcontroller ICs to confirm functional category alignment.

The R7F701331AEAFP#KA1 meets all substitution criteria as an active product variant within the same base product family, offering continued availability while maintaining full parameter equivalence.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: The R7F701331AEAFP#KA1 is classified as an active product, whereas the R7F701331AEAFP#KA2 is obsolete. This status difference directly impacts long-term supply chain viability and future component availability.

Compliance Alignment: Both parts maintain identical ROHS3 compliance and REACH Unaffected status, confirming regulatory equivalence for applications subject to environmental standards.

Inventory Status: The substitute part demonstrates superior inventory availability with 1001 pieces in stock compared to 760 pieces for the obsolete variant, providing enhanced procurement reliability.

Functional Equivalence: Both parts share the R7F701331 base product number and identical MSL classification, confirming core functional and handling equivalence.

For new designs or long-term production requirements, the R7F701331AEAFP#KA1 provides sustained availability and active manufacturer support. For existing applications currently utilizing the R7F701331AEAFP#KA2, transition to the active variant ensures continued component sourcing beyond the obsolete part's remaining inventory.

Frequently Asked Questions (FAQ)

Q: Can the R7F701331AEAFP#KA1 directly replace the R7F701331AEAFP#KA2 in existing designs?

A: Yes. Both parts share the identical base product number R7F701331 and maintain equivalent regulatory compliance (ROHS3, REACH Unaffected) and moisture sensitivity specifications (MSL 3, 168 Hours). The functional microcontroller core remains unchanged between variants.

Q: What is the significance of the packaging designation difference (LFQFP versus LQFP)?

A: The packaging designation indicates the specific quad flat pack variant. Both designations represent quad flat pack configurations from Renesas Electronics Corporation. Verify PCB footprint compatibility with your specific board design before component selection.

Q: Why is the R7F701331AEAFP#KA2 classified as obsolete?

A: Obsolete classification indicates that Renesas Electronics Corporation has discontinued production of this specific part variant. The R7F701331AEAFP#KA1 remains in active production, providing continued manufacturer support and availability.

Q: Are there any differences in handling or storage requirements between these parts?

A: No. Both parts maintain identical Moisture Sensitivity Level 3 (168 Hours) classification, requiring identical handling, storage, and assembly process conditions.

Q: What inventory considerations should influence part selection?

A: The R7F701331AEAFP#KA1 offers higher current inventory availability (1001 pieces) compared to the obsolete variant (760 pieces). For applications requiring sustained component supply, the active variant provides superior long-term procurement reliability.
