Substitute Part Grouping Explanation

Substitution of the R5F571MLGDFB#30 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Identical processor core (RXv2)
• Identical series designation (RX71M)
• Identical operating frequency (240MHz)
• Identical memory configuration (4MB FLASH, 512K RAM, 64K EEPROM)
• Identical I/O count (111 pins)
• Identical voltage supply range (2.7V ~ 3.6V)
• Identical peripheral set (CANbus, EBI/EMI, Ethernet, I2C, MMC/SD, QSPI, SCI, SPI, SSI, USB OTG)
• Identical data converter specifications (A/D 8x12b, 21x12b; D/A 2x12b)

Mechanical Equivalence Criteria:

• Identical package type (144-LQFP)
• Identical package dimensions (20x20)
• Identical mounting type (Surface Mount)
• Identical thermal and environmental specifications

Compliance Equivalence Criteria:

• ROHS3 compliance
• Identical MSL rating (3)
• Identical REACH status (REACH Unaffected)

The substitute parts R5F571MLDDFB#30 and R5F571MLHDFB#30 meet all electrical, mechanical, and compliance criteria for direct substitution. Differentiation between parts is limited to packaging format (Tray) and product status.
