Substitute Part Grouping Explanation

Substitution of the DSPIC33FJ32MC101-E/SS is determined by strict equivalence across core electrical and mechanical parameters. The substitute part DSPIC33FJ32MC101-I/SS maintains identical specifications in the following critical areas:

Core Architecture: Both parts use the dsPIC core processor with 16-bit architecture and 16 MIPs execution speed.

Memory Configuration: Identical 32KB FLASH program memory (11K x 24) and 1K x 16 RAM capacity.

Peripheral Set: Matching I/O count (15 pins), connectivity interfaces (I2C, IrDA, LINbus, SPI, UART/USART), and peripheral functions (Brown-out Detect/Reset, Motor Control PWM, POR, PWM, WDT).

Package Specification: Both use 20-SSOP surface mount packaging with identical physical dimensions (0.209", 5.30mm Width).

Voltage Supply: Identical 3V ~ 3.6V operating range.

Data Conversion: Matching A/D converter specification (6x10b).

Compliance: Both maintain ROHS3 compliance and identical ECCN/HTSUS classifications.

The primary difference is the operating temperature range and product status, which are addressed in the engineering selection section.

Parameter Comparison

Engineering Selection Recommendations

The DSPIC33FJ32MC101-I/SS is the direct active equivalent for the obsolete DSPIC33FJ32MC101-E/SS. Both parts are manufactured by Microchip Technology and share identical core architecture, memory configuration, peripheral set, and package specifications.

For applications operating within the -40°C ~ 85°C temperature range, the DSPIC33FJ32MC101-I/SS provides full functional equivalence with the advantage of active product status and current manufacturing support. The substitute part maintains ROHS3 compliance and identical electrical specifications across all critical parameters.

For applications requiring operation above 85°C up to 125°C, the temperature derating of the substitute part must be evaluated against specific application requirements. In such cases, alternative dsPIC™ 33F series devices with extended temperature ratings should be considered.

The DSPIC33FJ32MC101-I/SS is supplied in Tube packaging, whereas the original part packaging format is not specified. Packaging format compatibility with existing assembly processes should be confirmed during procurement.

Frequently Asked Questions (FAQ)

Q: Are DSPIC33FJ32MC101-E/SS and DSPIC33FJ32MC101-I/SS pin-compatible?

A: Yes. Both devices use identical 20-SSOP packaging with the same physical dimensions (0.209", 5.30mm Width) and pin configuration. Direct PCB substitution is possible without layout modifications.

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

A: The suffix designates the operating temperature grade. The -E/SS variant operates from -40°C to 125°C, while the -I/SS variant operates from -40°C to 85°C. The -I/SS is the active production equivalent.

Q: Can I use DSPIC33FJ32MC101-I/SS in an application designed for -40°C ~ 125°C operation?

A: Only if your actual operating temperature does not exceed 85°C. If sustained operation above 85°C is required, the substitute part is not suitable. Consult Microchip Technology for extended-temperature alternatives within the dsPIC™ 33F series.

Q: Are the memory specifications identical between these parts?

A: Yes. Both parts contain 32KB FLASH program memory (11K x 24), 1K x 16 RAM, and identical A/D converter configuration (6x10b). Code and data storage capacity is equivalent.

Q: What connectivity interfaces are available on both parts?

A: Both DSPIC33FJ32MC101-E/SS and DSPIC33FJ32MC101-I/SS include I2C, IrDA, LINbus, SPI, and UART/USART interfaces. Peripheral functionality is identical.

Q: Is the DSPIC33FJ32MC101-I/SS still in production?

A: Yes. The DSPIC33FJ32MC101-I/SS is classified as Active product status with current manufacturing availability. The original -E/SS variant is Obsolete.

Q: Do both parts meet automotive qualification standards?

A: The DSPIC33FJ32MC101-E/SS carries AEC-Q100 qualification. Automotive qualification status for the DSPIC33FJ32MC101-I/SS is not specified in the provided data and should be confirmed with Microchip Technology if automotive compliance is required.
