Package Compatibility: Both parts utilize identical 80-LFQFP (12x12) surface mount packaging, enabling direct PCB layout compatibility without redesign.

Supply Chain Continuity: Current inventory of the substitute part (859 units) provides immediate availability compared to the obsolete original part, supporting production schedules and project timelines.

Frequently Asked Questions (FAQ)

Q: Can the R7F7010164AFP-C#KA4 be used as a direct replacement for the R7F7010164AFP#KA4 in existing designs?

A: Yes. Both parts share identical core processor architecture, memory specifications, operating voltage ranges, temperature ratings, and package dimensions. No PCB modifications or firmware changes are required for substitution.

Q: Are there differences in the part numbering between the original and substitute?

A: The part numbers differ only in the suffix designation: the original uses AFP#KA4 while the substitute uses AFP-C#KA4. This suffix change reflects the product status transition from obsolete to active production. The base product number R7F7010164 remains identical.

Q: What is the significance of the 80-LFQFP (12x12) package specification?

A: This designation indicates a 80-pin Low-Profile Quad Flat Package with 12mm x 12mm dimensions. Both the original and substitute parts use this identical package, ensuring mechanical and electrical compatibility on PCBs designed for either part.

Q: Do both parts support the same connectivity protocols?

A: Yes. Both the R7F7010164AFP#KA4 and R7F7010164AFP-C#KA4 support identical connectivity options: CANbus, CSI, I2C, LINbus, SPI, and UART/USART. Peripheral support including DMA, I2S, LCD, LVD, POR, PWM, and WDT is also identical.

Q: What is the Moisture Sensitivity Level (MSL) for the substitute part?

A: The R7F7010164AFP-C#KA4 has an MSL rating of 3 (168 Hours), indicating standard moisture sensitivity handling requirements for surface mount components.

Q: Are there any differences in operating temperature ranges?

A: No. Both parts operate across the identical temperature range of -40°C to 125°C (TA), supporting applications in industrial and automotive environments.

Q: Why is the original part classified as obsolete?

A: The R7F7010164AFP#KA4 has reached end-of-life status with Renesas Electronics Corporation. The manufacturer has transitioned production to the R7F7010164AFP-C#KA4, which provides equivalent functionality with active manufacturing support.
