Frequently Asked Questions (FAQ)

Q: Can the M30873FHBGP#35 be used as a direct replacement for the M30873FHBGP#U5?

A: Yes. Both parts are functionally and electrically identical across all specified parameters. The substitute maintains the same core processor, memory configuration, operating frequency, voltage supply range, I/O count, connectivity interfaces, and peripheral set. The primary difference is product status: the original is obsolete while the substitute is in active production.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 100-LQFP package with identical pinout and mechanical dimensions. Surface mount assembly processes require no modification.

Q: What is the significance of the product status difference?

A: The M30873FHBGP#U5 is marked as obsolete, indicating Renesas Electronics Corporation has discontinued active production and support. The M30873FHBGP#35 maintains active status, ensuring continued availability, manufacturer technical support, and supply chain reliability for new designs and production runs.

Q: Are compliance certifications equivalent between the two parts?

A: Both parts share identical REACH status (REACH Unaffected) and export control classification (ECCN 3A991A2, HTSUS 8542.31.0001). The original part specifies ROHS3 compliance; equivalent compliance status for the substitute should be confirmed with Renesas Electronics Corporation documentation.

Q: What parameters determine substitution eligibility for this microcontroller?

A: Substitution is based on equivalence across core processor architecture, memory size and type, operating frequency, voltage supply range, I/O count, connectivity interfaces, peripheral feature set, data conversion specifications, package type, and operating temperature range. Any deviation in these parameters disqualifies a part as a direct substitute.
