Substitute Part Grouping Explanation

Substitution eligibility for the DSPIC33FJ32GP101-E/SS is determined by strict alignment of the following critical parameters:

• Core Processor: dsPIC
• Core Size: 16-Bit
• Speed: 16 MIPs
• Program Memory Size: 32KB (11K x 24)
• Program Memory Type: FLASH
• RAM Size: 1K x 16
• Voltage - Supply (Vcc/Vdd): 3V ~ 3.6V
• Data Converters: A/D 6x10b
• Number of I/O: 15
• Connectivity: I2C, IrDA, LINbus, SPI, UART/USART
• Peripherals: Brown-out Detect/Reset, POR, PWM, WDT
• Package / Case: 28-SSOP (0.209", 5.30mm Width)

The DSPIC33FJ32GP101-I/SS qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status: the -E/SS variant is Obsolete, while the -I/SS variant is Active.

Parameter Comparison

Engineering Selection Recommendations

The DSPIC33FJ32GP101-I/SS is the direct substitute for the DSPIC33FJ32GP101-E/SS. Both parts maintain identical electrical and functional specifications, with ROHS3 compliance and MSL 1 rating. The -I/SS variant is currently Active in production, whereas the -E/SS is Obsolete.

A critical consideration exists regarding operating temperature range: the -E/SS supports -40°C to 125°C, while the -I/SS supports -40°C to 85°C. For applications requiring operation above 85°C, the -E/SS specification must be retained, and alternative sourcing strategies should be evaluated. For applications within the -40°C to 85°C range, the -I/SS provides full functional equivalence with the advantage of active production status and supply availability.

Both variants carry AEC-Q100 automotive qualification and are suitable for automotive-grade applications.

Frequently Asked Questions (FAQ)

Q: Can DSPIC33FJ32GP101-I/SS directly replace DSPIC33FJ32GP101-E/SS in existing designs?

A: Yes, for applications operating within -40°C to 85°C. The electrical specifications, memory configuration, I/O count, connectivity options, and package are identical. The -I/SS is the active production equivalent.

Q: What is the significance of the -E and -I designations?

A: These designations indicate product status and temperature grade. The -E/SS is Obsolete with an extended temperature range (-40°C to 125°C). The -I/SS is Active with a standard automotive temperature range (-40°C to 85°C).

Q: Are there packaging differences between these parts?

A: No. Both parts use the 28-SSOP package with identical dimensions (0.209", 5.30mm Width). The -I/SS is supplied in Tube packaging, while the -E/SS packaging specification was not provided.

Q: Do both parts meet automotive compliance requirements?

A: Yes. Both DSPIC33FJ32GP101-E/SS and DSPIC33FJ32GP101-I/SS carry AEC-Q100 qualification and are ROHS3 compliant, suitable for automotive applications within their respective temperature ranges.

Q: What should be considered when transitioning from -E/SS to -I/SS?

A: Verify that your application operates within the -40°C to 85°C temperature range. If sustained operation above 85°C is required, alternative solutions must be evaluated. For all other parameters, the transition is direct with no design modifications required.
