Engineering Selection Recommendations

Direct Substitutes (Same Package Footprint 14x20):

R5F100PFDFA#50 and R5F100PFDFA#30 are direct substitutes for R5F100PFDFA#X0. Both maintain identical electrical specifications and the same 100-LQFP (14x20) package footprint. These parts carry Active product status and ROHS3 compliance with REACH Unaffected designation, providing superior lifecycle support compared to the obsolete original part.

R5F100PFAFA#10 and R5F100PFAFA#30 are parametric equivalents with identical functional specifications and 100-LQFP (14x20) footprint. These parts are supplied in Tray packaging and maintain Active status with full compliance certifications (ROHS3, REACH Unaffected).

Footprint-Compatible Substitutes (100-LQFP 14x14):

R5F100PFAFB#10, R5F100PFAFB#30, and R5F100PFDFB#10 are parametric equivalents with identical electrical and functional specifications but feature a smaller 100-LQFP (14x14) package footprint. These parts are suitable for applications where PCB space constraints permit the reduced package dimensions. All three maintain Active product status and full compliance certifications.

Product Status Consideration:

All substitute parts listed carry Active product status, ensuring long-term availability and manufacturing support. The original R5F100PFDFA#X0 is classified as Obsolete, making transition to an Active equivalent part essential for sustained production and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can R5F100PFDFA#50 directly replace R5F100PFDFA#X0 in existing designs?

A: Yes. R5F100PFDFA#50 is a direct substitute with identical electrical specifications, core functionality, and 100-LQFP (14x20) package footprint. The suffix change (#X0 to #50) reflects product lifecycle status transition from Obsolete to Active, with no functional impact.

Q: What is the difference between the 14x20 and 14x14 package variants?

A: Both are 100-LQFP packages with identical pin counts and electrical specifications. The difference is physical footprint size: 14x20mm versus 14x14mm. The 14x14 variant (R5F100PFAFB and R5F100PFDFB series) is suitable for space-constrained applications. Pin assignment and electrical function remain identical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 Compliant status. The original R5F100PFDFA#X0 also meets ROHS3 requirements. Active substitute parts additionally carry REACH Unaffected designation, providing enhanced regulatory compliance documentation.

Q: Why does the original part show Obsolete status?

A: R5F100PFDFA#X0 is classified as Obsolete by Renesas Electronics Corporation. Active equivalent parts (R5F100PFDFA#50, R5F100PFDFA#30, R5F100PFAFA#10, R5F100PFAFA#30, R5F100PFAFB#10, R5F100PFAFB#30, R5F100PFDFB#10) are available for new designs and ongoing production support.

Q: What packaging formats are available?

A: Substitute parts are supplied in two packaging formats: Tray (R5F100PFAFA and R5F100PFAFB series) and unspecified standard packaging (R5F100PFDFA and R5F100PFDFB series). Packaging format does not affect electrical or functional specifications.

Q: Are the connectivity and peripheral features identical across all substitute parts?

A: Yes. All substitute parts maintain identical connectivity (CSI, I2C, LINbus, UART/USART) and peripheral integration (DMA, LVD, POR, PWM, WDT). Core processor architecture, memory configuration, and I/O count are functionally equivalent across all listed substitutes.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All parts, including the original and all substitutes, carry MSL 3 rating with 168-hour floor life. Standard moisture control procedures during storage and handling apply uniformly across the entire part family.
