Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the R5F64189DFD#UB are identified based on strict parametric equivalence across the following critical criteria:

Core Electrical Parameters: Core processor (R32C/100), core size (16/32-Bit), operating speed (50MHz), program memory capacity (1MB FLASH), EEPROM size (8K x 8), and RAM size (63K x 8) must remain identical.

Connectivity & Peripherals: All substitute parts must maintain identical connectivity interfaces (CANbus, EBI/EMI, I2C, IEBus, UART/USART) and peripheral sets (DMA, LVD, PWM, WDT).

Physical & Environmental Specifications: Voltage supply range (3V ~ 5.5V), operating temperature range (-40°C ~ 85°C), I/O count (120), and package type (144-LQFP) must match exactly.

Compliance & Certifications: RoHS3 compliance and REACH unaffected status are maintained across all substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both R5F64179DFD#2B and R5F64189PFD#UB are parametrically equivalent to the R5F64189DFD#UB across all critical electrical, functional, and physical specifications. The primary distinction lies in product status and moisture sensitivity characteristics.

R5F64179DFD#2B: This substitute maintains active product status within the M16C/R32C/100/117 series variant. It provides full parametric equivalence with identical core processor, memory configuration, connectivity, and peripheral integration. MSL rating of 3 (168 Hours) matches the original part.

R5F64189PFD#UB: This substitute shares the same base product number (R5F64189) and series designation (M16C/R32C/100/118) as the original part, indicating closest functional alignment. It maintains active product status and offers superior moisture sensitivity characteristics with MSL rating of 1 (Unlimited), providing extended shelf life and reduced handling constraints compared to the original obsolete part.

Selection between substitutes depends on procurement availability, supply chain requirements, and handling environment specifications. Both parts satisfy identical electrical and functional requirements for direct replacement applications.

Frequently Asked Questions (FAQ)

Q: Can R5F64179DFD#2B replace R5F64189DFD#UB in existing designs?

A: Yes. The R5F64179DFD#2B maintains identical core processor architecture (R32C/100), memory configuration (1MB FLASH, 63K RAM, 8K EEPROM), operating speed (50MHz), voltage supply range (3V ~ 5.5V), I/O count (120), connectivity interfaces, and peripheral sets. The series designation difference (100/117 versus 100/118) reflects internal variant classification but does not affect parametric equivalence for substitution purposes.

Q: What is the difference between R5F64189PFD#UB and the original R5F64189DFD#UB?

A: Both parts share identical base product number (R5F64189) and series designation (M16C/R32C/100/118), indicating they are variants within the same product line. The primary differences are product status (original is obsolete; substitute is active) and moisture sensitivity level (original MSL 3 at 168 Hours; substitute MSL 1 with unlimited shelf life). All electrical and functional parameters remain identical.

Q: Are all three parts compatible with the same PCB layout and footprint?

A: Yes. All three parts utilize the 144-LQFP (20x20mm) package with identical pin configuration, I/O count (120), and surface mount mounting type. PCB layout, footprint, and assembly processes require no modification for substitution.

Q: What compliance certifications apply to these substitute parts?

A: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original part's regulatory classification. No additional compliance verification is required for substitution in applications where the original part met regulatory requirements.

Q: Does the MSL difference between R5F64189PFD#UB (MSL 1) and the original part (MSL 3) affect functionality?

A: No. Moisture sensitivity level (MSL) classification affects component handling, storage, and shelf life requirements, not electrical performance or functional operation. MSL 1 (unlimited shelf life) provides more favorable storage conditions compared to MSL 3 (168 hours), but both parts deliver identical in-circuit performance.
