Substitute Part Grouping Explanation

The MSP430F5528IRGCT qualifies as a direct substitute for the MSP430F5528IRGC based on identical electrical and functional specifications. Both parts share the same base product number (MSP430F5528), core processor architecture (MSP430 CPUXV2), memory configuration (128KB FLASH, 10KB RAM), clock speed (25MHz), supply voltage range (1.8V ~ 3.6V), I/O count (47), connectivity interfaces, and peripheral set. The substitution is valid across all functional and electrical parameters.

The primary distinction between these parts is packaging format and product status. The MSP430F5528IRGC is supplied in tube packaging and carries obsolete status, while the MSP430F5528IRGCT is supplied in Cut Tape (CT) and Digi-Reel® packaging and maintains active product status. Both parts are RoHS3 compliant and REACH unaffected.

Engineering Selection Recommendations

The MSP430F5528IRGCT is the appropriate selection for new designs and ongoing production requirements. This part maintains active product status with Texas Instruments, ensuring long-term availability and supply chain stability. Both parts are functionally and electrically identical, with no differences in core processor architecture, memory configuration, clock speed, voltage specifications, or peripheral functionality.

The MSP430F5528IRGC, classified as obsolete, should be replaced with the MSP430F5528IRGCT in production environments. The transition involves no circuit redesign or firmware modification, as electrical and functional compatibility is complete. The only consideration is packaging format: the MSP430F5528IRGCT is supplied in Cut Tape and Digi-Reel® formats, which may require adjustment to component handling and placement procedures if transitioning from tube packaging.

Both parts maintain RoHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications.
