Engineering Selection Recommendations

The M30879FLGP#U5 is classified as obsolete. Both substitute parts—M30879FLGP#35 and M30879FLAGP#35—are active products from Renesas Electronics Corporation and maintain full electrical and mechanical equivalence to the original part.

M30879FLGP#35 is designated as the manufacturer-recommended substitute. This part carries active product status and is available in higher inventory (871 units), making it the primary choice for replacement applications.

M30879FLAGP#35 is a parametric equivalent with identical electrical specifications and package configuration. This part is also active and maintains robust inventory availability (1,093 units).

Both substitute parts comply with ROHS3 requirements and maintain REACH unaffected status, ensuring regulatory compliance for new designs and production updates. Selection between the two substitutes should be based on availability, lead time, and procurement channel preferences, as all electrical and mechanical parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can M30879FLGP#35 or M30879FLAGP#35 be used as direct replacements for M30879FLGP#U5?

A: Yes. Both parts are functionally equivalent. They share identical core processor architecture, memory configuration, operating frequency, I/O count, package type, and peripheral feature set. No design modifications are required for substitution.

Q: What is the difference between M30879FLGP#35 and M30879FLAGP#35?

A: Both parts are parametrically equivalent with identical electrical specifications. The difference lies in the part number suffix, which may indicate different manufacturing batches or internal Renesas product line designations. Both are active products suitable for production use.

Q: Are there any compatibility concerns with the 100-LQFP package?

A: No. All three parts use the same 100-LQFP (14x14mm) surface mount package. PCB footprints, pin assignments, and mechanical mounting requirements are identical.

Q: Why is the original M30879FLGP#U5 marked as obsolete?
