Engineering Selection Recommendations

R5F100GFGNA#40 (MFR Recommended Substitute)

The R5F100GFGNA#40 is designated as the manufacturer-recommended substitute for the obsolete R5F100GFDNA#W0. This part maintains complete functional and electrical equivalence across all core parameters including processor architecture, memory configuration, I/O count, connectivity interfaces, and peripheral functions. The R5F100GFGNA#40 carries Active product status with ROHS3 compliance certification and is available in Tape & Reel packaging. The operating temperature range extends to -40°C ~ 105°C, providing enhanced thermal capability. The minimum supply voltage is specified at 2.4V, which represents a narrower lower bound compared to the original part's 1.6V specification. Applications operating below 2.4V require evaluation against actual circuit requirements.

R5F100GFANA#40 (Parametric Equivalent Substitute)

The R5F100GFANA#40 provides parametric equivalence to the R5F100GFDNA#W0 with identical core architecture, memory capacity, I/O configuration, and operating temperature range (-40°C ~ 85°C). This part maintains the original supply voltage specification of 1.6V ~ 5.5V, ensuring compatibility with designs requiring operation at lower voltage thresholds. The R5F100GFANA#40 carries Active product status with ROHS3 compliance certification and is available in Tape & Reel packaging. This part is suitable for applications requiring strict voltage range compatibility with the original design specification.

Both substitute parts are manufactured by Renesas Electronics Corporation and maintain identical physical packaging (48-HWQFN 7x7) and moisture sensitivity characteristics (MSL 3, 168 Hours).
