Engineering Selection Recommendations

R5F64179DFD#2B: This substitute part maintains complete electrical and mechanical compatibility with the R5F64189DFD#2B across all specified parameters. The primary distinction is series designation (M16C/R32C/100/117 versus M16C/R32C/100/118) and product status. R5F64179DFD#2B carries Active product status, ensuring ongoing availability and support. Both parts are ROHS3 compliant and REACH unaffected. This part is suitable for direct substitution in applications requiring the specified electrical and mechanical characteristics.

R5F64189PFD#UB: This substitute part shares the identical base product number (R5F64189) and series designation (M16C/R32C/100/118) as the main part, maintaining complete electrical and mechanical compatibility. The primary distinction is the package suffix designation (PFD#UB versus DFD#2B) and moisture sensitivity level (MSL 1 Unlimited versus MSL 3 168 Hours). R5F64189PFD#UB carries Active product status with superior moisture handling characteristics. This part is suitable for direct substitution and offers enhanced reliability in moisture-sensitive environments.

Both substitute parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements equivalent to the main part.

Frequently Asked Questions (FAQ)

Q: Can R5F64179DFD#2B be used as a direct replacement for R5F64189DFD#2B?

A: Yes. R5F64179DFD#2B maintains identical electrical specifications and package form factor. The series designation differs (117 versus 118), but all functional parameters including processor core, memory configuration, speed, voltage range, I/O count, connectivity, and peripherals are equivalent.

Q: What is the difference between R5F64189DFD#2B and R5F64189PFD#UB?

A: Both parts share the same base product number and series designation. The primary differences are the package suffix designation and moisture sensitivity level. R5F64189PFD#UB has MSL 1 (Unlimited) compared to MSL 3 (168 Hours) for the main part, providing superior moisture protection. Both are electrically and mechanically identical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both R5F64179DFD#2B and R5F64189PFD#UB are ROHS3 compliant and REACH unaffected, matching the regulatory status of the main part R5F64189DFD#2B.

Q: What is the significance of product status (Obsolete versus Active)?

A: Product status indicates lifecycle phase. The main part R5F64189DFD#2B is Obsolete, meaning it is no longer in production. Both substitute parts carry Active status, indicating current production and ongoing availability. Active status ensures continued supply and technical support.

Q: Are the 144-LFQFP packages identical across all three parts?

A: Yes. All three parts use the 144-LFQFP (20x20) surface mount package with identical pin count and physical dimensions. They are mechanically interchangeable on PCB layouts designed for this package form factor.

Q: Can I use these parts interchangeably in the same circuit board design?

A: Yes. All three parts maintain identical electrical specifications, pin configurations, and package dimensions. They are suitable for direct substitution in circuit designs originally specified for the R5F64189DFD#2B.

Q: What is the difference in moisture sensitivity between the substitute parts?

A: R5F64189PFD#UB has MSL 1 (Unlimited moisture exposure), while R5F64189DFD#2B and R5F64179DFD#2B have MSL 3 (168 hours maximum). MSL 1 provides superior protection in high-humidity storage and handling environments.
