Substitute Part Grouping Explanation

Substitute parts for the R5F51306ADFN#30 are identified based on strict parametric equivalence within the RX130 microcontroller family. The substitution criteria are:

• Identical core processor architecture (RX)
• Identical core size (32-Bit Single-Core)
• Identical operating frequency (32MHz)
• Identical program memory capacity (256KB FLASH)
• Identical EEPROM size (8K x 8)
• Identical RAM size (32K x 8)
• Identical I/O count (68 pins)
• Identical package type (80-LQFP 12x12)
• Identical voltage supply range (1.8V ~ 5.5V)
• Identical data converter specifications (A/D 17x12b, D/A 2x8b)
• Identical operating temperature range (-40°C ~ 85°C)
• Identical compliance certifications (ROHS3, REACH Unaffected)

The R5F51306BDFN#10 and R5F51306BDFN#30 meet all these criteria. The suffix designations (#10 and #30) indicate packaging quantity variations (Tray packaging), while the "B" revision designation reflects product status differences and minor peripheral enhancements (addition of Capacitive Touch peripheral).

Parameter Comparison

Engineering Selection Recommendations

The R5F51306BDFN#10 and R5F51306BDFN#30 are direct parametric equivalents to the discontinued R5F51306ADFN#30. Both substitute parts maintain identical electrical specifications, memory configurations, I/O architecture, and thermal operating ranges. The primary distinction between the substitutes is packaging quantity designation, with both available in Tray packaging format.

Selection between R5F51306BDFN#10 and R5F51306BDFN#30 should be based on inventory availability and procurement requirements. R5F51306BDFN#30 currently maintains significantly higher stock levels (103,601 units) compared to R5F51306BDFN#10 (1,903 units), supporting extended production schedules and supply chain continuity.

Both substitute parts carry Active product status from Renesas Electronics Corporation, ensuring continued manufacturer support, documentation availability, and long-term supply viability. All three parts maintain identical ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and consumer applications.

Frequently Asked Questions (FAQ)

Q: Can R5F51306BDFN#10 or R5F51306BDFN#30 be used as direct replacements for R5F51306ADFN#30?

A: Yes. Both substitute parts are parametrically equivalent across all critical electrical and mechanical specifications. Identical core architecture, memory configuration, I/O count, package type, and operating parameters ensure functional compatibility without design modification.

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

A: The suffix designations indicate packaging quantity variations. Both parts use identical Tray packaging format and are functionally equivalent. The designation reflects supplier packaging configurations for different order quantities.

Q: Are there connectivity or peripheral differences between the main part and substitutes?

A: The substitute parts (R5F51306BDFN series) include an additional Capacitive Touch peripheral not listed in the main part specifications. All other connectivity interfaces (I2C, LINbus, SCI, SPI) and peripherals (DMA, LVD, POR, PWM, WDT) remain identical.

Q: What is the impact of the product status change from Discontinued to Active?

A: Active product status ensures continued manufacturer support, availability of technical documentation, and long-term supply chain reliability. The discontinued status of the original part makes substitution necessary for ongoing production requirements.

Q: Are there any thermal or voltage supply considerations for substitution?

A: No. Both substitute parts maintain identical operating temperature range (-40°C ~ 85°C) and voltage supply specifications (1.8V ~ 5.5V), ensuring compatibility with existing thermal management and power supply designs.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. Both R5F51306BDFN#10 and R5F51306BDFN#30 maintain ROHS3 compliance and REACH unaffected status, identical to the original part. MSL rating remains 3 (168 Hours) for all three parts.
