Substitution Categories:

Category 1: Parametric Equivalents (RL78/G13 Series) Parts R5F100GLAFB#30, R5F100GLDFB#10, and R5F100GLDFB#30 are parametric equivalents of the R5F100GLAFB#10. These parts share identical electrical specifications, memory configurations, I/O count, connectivity options, and peripheral sets. Differences exist only in packaging tape reel designations (suffix #10 versus #30), which indicate different quantity packaging formats for the same device. All three parts maintain the same 48-LFQFP (7x7) package footprint and are functionally interchangeable at the circuit level.

Category 2: Series Variant (RL78/G13A Series) Part R5F140GLAFB#30 represents a series variant from the RL78/G13A product line. This part maintains all critical electrical and functional parameters identical to the R5F100GLAFB#10, including core processor architecture, clock speed, memory configuration, I/O count, and peripheral set. The part number prefix change (R5F140 versus R5F100) and series designation (RL78/G13A versus RL78/G13) indicate an enhanced variant within the RL78 family. All compliance certifications, package specifications, and operating characteristics remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status with Renesas Electronics Corporation, ensuring continued manufacturer support and availability. Selection between R5F100GLAFB#10 and its parametric equivalents (R5F100GLAFB#30, R5F100GLDFB#10, R5F100GLDFB#30) is determined by packaging format requirements. The suffix designations (#10 versus #30) indicate different tape reel quantities; the electrical and functional specifications are identical. These parts are directly interchangeable at the circuit level.

The R5F140GLAFB#30 represents an enhanced variant from the RL78/G13A series. This part maintains complete electrical and functional equivalence to the R5F100GLAFB#10 while offering the benefits of the newer G13A architecture. Selection of the R5F140GLAFB#30 is appropriate when leveraging the latest RL78 family enhancements while maintaining identical system-level performance.

All substitute parts comply with ROHS3 regulations and maintain REACH Unaffected status, ensuring regulatory compliance across global markets. Moisture Sensitivity Level 3 (168 Hours) is consistent across all parts, requiring identical handling and storage protocols. The 48-LFQFP (7x7) package footprint is uniform across all substitutes, enabling direct PCB layout compatibility without redesign.
