Engineering Selection Recommendations

The R5F104BFDFP#V0 is classified as obsolete. Direct substitution is available through R5F104BFDFP#30, which maintains identical electrical and mechanical specifications while offering active product status and improved availability. This part is recommended as the primary replacement for new designs and production continuity.

Parametric equivalents R5F104BFAFP#10 and R5F104BFAFP#30 provide identical functional and electrical characteristics with active product status. These alternatives differ only in packaging designation (Tray) and are suitable for applications where the original packaging specification is not a constraint. Both parametric equivalents are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Selection between R5F104BFDFP#30 and the parametric equivalents should be based on packaging requirements and supply chain availability. All three substitute parts are functionally interchangeable with the obsolete R5F104BFDFP#V0 for applications requiring RL78/G14 microcontroller functionality.

Frequently Asked Questions (FAQ)

Q: Can R5F104BFDFP#30 be used as a direct replacement for R5F104BFDFP#V0?

A: Yes. R5F104BFDFP#30 is a direct substitute with identical electrical specifications, memory configuration, I/O count, peripheral set, and 32-LQFP package. The primary difference is product status: R5F104BFDFP#30 is active while R5F104BFDFP#V0 is obsolete.

Q: What is the difference between R5F104BFDFP#30 and R5F104BFAFP#10/R5F104BFAFP#30?

A: All three parts are parametrically equivalent with identical core specifications. The difference lies in the packaging designation suffix. R5F104BFDFP#30 and R5F104BFAFP variants differ in their original packaging format, but all are supplied in 32-LQFP (7x7) surface mount packages. Selection depends on packaging availability and supply chain requirements.

Q: Are the substitute parts ROHS3 compliant?

A: Yes. R5F104BFDFP#30, R5F104BFAFP#10, and R5F104BFAFP#30 are all ROHS3 compliant with Moisture Sensitivity Level 3 (168 Hours).

Q: Can these parts be used in the same PCB layout as the original R5F104BFDFP#V0?

A: Yes. All substitute parts use the identical 32-LQFP (7x7) package with the same pin configuration, footprint, and mounting requirements. No PCB redesign is necessary.

Q: What is the operating temperature range for substitute parts?

A: All substitute parts operate across -40°C to 85°C (TA), matching the original R5F104BFDFP#V0 specification.

Q: Are there any differences in memory configuration between the main part and substitutes?

A: No. All parts feature 96KB FLASH program memory, 8KB EEPROM, and 12KB RAM with identical memory architecture and access specifications.
