Substitute Part Grouping Explanation

Substitution eligibility for the R5F109GAJFB#H0 is determined by the following criteria:

Manufacturer Alignment: Both the main part and substitute must be manufactured by Renesas Electronics Corporation to ensure design consistency and technical support continuity.

Base Product Family: Both components must share the R5F109 base product number, confirming membership in the same microcontroller family and ensuring architectural compatibility.

Regulatory Compliance: Substitute parts must maintain ROHS3 compliance, REACH unaffected status, and identical ECCN and HTSUS classifications to satisfy procurement and export requirements.

Packaging Classification: Both components utilize LFQFP packaging technology, ensuring mechanical and thermal compatibility within equivalent form factors.

Moisture Sensitivity: Substitute parts must maintain MSL 3 (168 Hours) rating to ensure equivalent handling, storage, and assembly process requirements.

The R5F109GACJFB#10 meets all substitution criteria and is classified as an active product, providing a viable alternative to the obsolete R5F109GAJFB#H0.

Engineering Selection Recommendations

The R5F109GACJFB#10 is the qualified substitute for the obsolete R5F109GAJFB#H0 based on the following engineering criteria:

Product Status Transition: The substitute part maintains active production status, ensuring long-term availability and supply chain stability compared to the obsolete main part.

Regulatory Compliance Continuity: Both components maintain identical ROHS3 compliance, REACH unaffected status, ECCN classification, and HTSUS coding, eliminating regulatory re-qualification requirements.

Moisture and Environmental Handling: Identical MSL 3 (168 Hours) ratings ensure that existing assembly, storage, and handling procedures remain valid without modification.

Manufacturer Support: Continued manufacturing by Renesas Electronics Corporation ensures access to technical documentation, application notes, and design support resources.

Family Compatibility: Shared R5F109 base product number and 16-bit core architecture provide functional alignment within the microcontroller family.

Selection of the R5F109GACJFB#10 eliminates obsolescence risk while maintaining compliance and operational compatibility with existing system requirements.

Frequently Asked Questions (FAQ)

Q: Why is the R5F109GAJFB#H0 classified as obsolete?

A: The R5F109GAJFB#H0 has been discontinued by Renesas Electronics Corporation and is no longer in active production. Obsolete classification indicates that new inventory from the manufacturer is unavailable, making substitute parts necessary for ongoing procurement.

Q: What determines if a part can substitute for the R5F109GAJFB#H0?

A: Substitution eligibility requires: identical manufacturer (Renesas Electronics Corporation), shared R5F109 base product number, matching LFQFP packaging classification, identical RoHS3 compliance status, matching MSL 3 (168 Hours) rating, and identical ECCN and HTSUS codes.

Q: Is the R5F109GACJFB#10 a direct replacement?

A: The R5F109GACJFB#10 is a qualified substitute that meets all regulatory, environmental, and family-level compatibility criteria. Both components share the R5F109 base product number, 16-bit core architecture, LFQFP packaging, and identical compliance certifications.

Q: Are there packaging differences between these parts?

A: Both components utilize LFQFP packaging technology. The R5F109GACJFB#10 is specified as 48-LQFP (7x7), providing mechanical and thermal compatibility within equivalent form factors.

Q: What is the significance of the MSL 3 (168 Hours) rating?

A: MSL 3 (168 Hours) indicates moisture sensitivity level 3 with a floor life of 168 hours after moisture exposure. Identical ratings between the main part and substitute ensure that existing assembly, storage, and handling procedures remain valid without modification.

Q: Does the substitute part require design re-qualification?

A: The R5F109GACJFB#10 maintains identical ROHS3 compliance, REACH unaffected status, ECCN classification, and HTSUS coding as the main part. Regulatory re-qualification is not required based on these compliance parameters.

Q: What is the inventory status of the substitute part?

A: The R5F109GACJFB#10 is currently in active production with 963 pieces available in new original stock, providing reliable supply chain access compared to the obsolete main part.
