Substitute Part Grouping Explanation

Substitution eligibility for the R5F100JGDFA#X0 is determined by strict equivalence across the following critical parameters: core processor architecture (RL78), core size (16-Bit), clock speed (32MHz), program memory capacity and type (128KB FLASH), EEPROM size (8K x 8), RAM capacity (12K x 8), I/O pin count (38), supply voltage range (1.6V ~ 5.5V), data converter specifications (A/D 12x8/10b), connectivity interfaces (CSI, I2C, LINbus, UART/USART), peripheral feature set (DMA, LVD, POR, PWM, WDT), package type (52-LQFP 10x10), and operating temperature range (-40°C ~ 85°C).

The R5F100JGDFA#50 qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications. The distinction between these parts lies in product status and packaging designation suffix, with the #50 variant maintaining active production status.

Parameter Comparison

Engineering Selection Recommendations

The R5F100JGDFA#50 is the appropriate selection for applications currently specified with the R5F100JGDFA#X0. Both parts maintain identical electrical and mechanical specifications, ensuring functional compatibility at the circuit level. The primary distinction is product lifecycle status: the #X0 variant is obsolete, while the #50 variant is in active production.

Selection of the R5F100JGDFA#50 provides continuity of supply, compliance with current RoHS3 and REACH regulations, and alignment with active component procurement practices. Both variants carry identical MSL ratings and environmental compliance certifications, eliminating compliance-related substitution barriers.

Frequently Asked Questions (FAQ)

Q: Are R5F100JGDFA#X0 and R5F100JGDFA#50 pin-compatible?

A: Yes. Both parts use the 52-LQFP (10x10) package with identical pin assignments, electrical characteristics, and I/O configurations. Direct PCB-level substitution is supported without layout modifications.

Q: What is the significance of the suffix difference (#X0 versus #50)?

A: The suffix designates packaging or distribution variants within the same base product number (R5F100). The #50 variant is currently in active production, while the #X0 variant is obsolete. Electrical and functional specifications remain identical.

Q: Do both parts meet the same environmental compliance standards?

A: Yes. Both R5F100JGDFA#X0 and R5F100JGDFA#50 are ROHS3 compliant, REACH unaffected, and carry MSL rating 3 (168 Hours). No compliance-related substitution restrictions apply.

Q: Can the R5F100JGDFA#50 be used in designs originally specified for the R5F100JGDFA#X0?

A: Yes. Complete parameter equivalence across core processor, memory configuration, I/O count, voltage supply range, connectivity interfaces, and peripheral features supports direct substitution in existing designs without firmware or hardware modifications.

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

A: Both parts operate across -40°C to 85°C (TA), supporting industrial and extended commercial temperature applications without thermal performance differentiation.
