Engineering Selection Recommendations

All substitute parts listed maintain Active product status with ROHS3 compliance and REACH unaffected classification, ensuring regulatory alignment with current environmental and hazardous substance directives.

Selection by Package Geometry:

64-LQFP (14x14mm) Package: R5F104LCAFP#10 and R5F104LCAFP#30 are direct footprint equivalents. Selection between these variants depends on packaging quantity requirements (#10 or #30 designations). The R5F104LCAFP#10 maintains the largest package footprint, suitable for applications where PCB real estate is not constrained.

64-LQFP (12x12mm) Package: R5F104LCAFA#10 and R5F104LCAFA#30 provide a reduced footprint variant while maintaining identical electrical specifications. This package geometry accommodates space-constrained PCB layouts without functional compromise.

64-LFQFP (10x10mm) Package: R5F104LCAFB#10 and R5F104LCAFB#30 represent the most compact package option. This variant is suitable for high-density PCB designs requiring minimal component footprint.

Selection by Packaging Quantity:

The suffix designation (#10 or #30) indicates packaging quantity per reel or tray. Selection between these variants is determined by procurement volume requirements and inventory management practices. Electrical and functional characteristics remain identical across all packaging variants.

All substitute parts are manufactured by Renesas Electronics Corporation and maintain identical core specifications, ensuring seamless functional interchangeability within the RL78/G14 microcontroller series.

Frequently Asked Questions (FAQ)

Q: Can R5F104LCAFP#10 be replaced with R5F104LCAFA#10 or R5F104LCAFB#10?

A: Yes. All three parts are functionally equivalent across all electrical parameters, memory specifications, connectivity options, and peripheral features. The differences are limited to physical package dimensions. R5F104LCAFA#10 uses a 64-LQFP (12x12mm) package, and R5F104LCAFB#10 uses a 64-LFQFP (10x10mm) package. PCB layout and footprint compatibility must be verified before substitution.

Q: What is the difference between the #10 and #30 packaging designations?

A: The #10 and #30 suffixes indicate different packaging quantities per reel or tray. Both variants contain identical microcontroller dies with identical electrical specifications. Selection is based on procurement volume and inventory requirements, not functional capability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts, including R5F104LCAFP#10, R5F104LCAFA#10, R5F104LCAFA#30, R5F104LCAFB#10, R5F104LCAFB#30, and R5F104LCAFP#30, are ROHS3 compliant with REACH unaffected status.

Q: Do package geometry differences affect electrical performance?

A: No. Package geometry variations (14x14mm, 12x12mm, or 10x10mm) do not alter electrical performance, processing speed, memory capacity, or peripheral functionality. All variants operate at 32MHz with identical 32KB FLASH, 4KB EEPROM, and 4KB RAM configurations.

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

A: All substitute parts maintain MSL 3 (168 Hours) classification. This indicates the maximum time the component can be exposed to ambient conditions of 30°C and 85% relative humidity before soldering.

Q: Can I use R5F104LCAFB#10 in place of R5F104LCAFP#10 on an existing PCB?

A: Direct PCB substitution is not possible without layout modification. R5F104LCAFB#10 uses a 64-LFQFP (10x10mm) package, while R5F104LCAFP#10 uses a 64-LQFP (14x14mm) package. The footprints are different and require PCB redesign. However, the microcontroller functionality is identical, making it suitable for new PCB designs with space constraints.

Q: Are all substitute parts manufactured by Renesas Electronics Corporation?

A: Yes. All substitute parts listed are manufactured by Renesas Electronics Corporation and are part of the RL78/G14 microcontroller series.

Q: What operating temperature range applies to all substitute parts?

A: All substitute parts operate across the identical temperature range of -40°C to 85°C (TA), ensuring consistent thermal performance across all variants.
