The PIC24F08KA102-I/SP qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and operating temperature range, which do not affect functional equivalence in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The PIC24F08KA102-I/SP is a direct functional equivalent to the PIC24F08KA102-E/SP. Both devices are ROHS3 compliant and carry identical MSL ratings, ensuring compatibility with standard manufacturing and assembly processes.

The primary distinction is product status: the -E/SP variant is obsolete, while the -I/SP variant maintains active status with current manufacturer support. The -I/SP also features a reduced operating temperature range (-40°C to 85°C versus -40°C to 125°C), which is suitable for standard industrial and commercial applications but may require evaluation for high-temperature environments.

For new designs or production continuity, the PIC24F08KA102-I/SP is the appropriate selection due to its active product status and ongoing availability. Existing designs using the -E/SP variant can transition to the -I/SP without modification, provided the operating temperature range of -40°C to 85°C is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can the PIC24F08KA102-I/SP be used as a direct replacement for the PIC24F08KA102-E/SP?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters, including memory configuration, I/O count, connectivity interfaces, and peripheral features. The -I/SP variant is the active production equivalent.

Q: What is the difference between the -E/SP and -I/SP designations?

A: The suffix designates the temperature grade and product status. The -E/SP is an obsolete variant rated for -40°C to 125°C operation. The -I/SP is the active equivalent rated for -40°C to 85°C operation. Both use identical 28-DIP packaging and core architecture.

Q: Are there any compatibility concerns when switching from PIC24F08KA102-E/SP to PIC24F08KA102-I/SP?

A: No compatibility concerns exist for applications operating within the -40°C to 85°C temperature range. Applications requiring operation above 85°C must evaluate the reduced temperature specification of the -I/SP variant.

Q: What packaging options are available for this microcontroller?

A: Both the -E/SP and -I/SP variants are supplied in 28-DIP (0.300", 7.62mm) through-hole packaging. The -I/SP is available in tube packaging format.

Q: Are both parts RoHS compliant?

A: Yes. Both the PIC24F08KA102-E/SP and PIC24F08KA102-I/SP are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity level).
