Substitute Part Grouping Explanation

Substitution eligibility for the PIC24F16KM202-E/SS is determined by strict equivalence across the following critical parameters:

• Core processor architecture (PIC 16-bit)
• Program memory capacity (16KB FLASH)
• RAM and EEPROM sizes (2K x 8 and 512 x 8 respectively)
• Operating frequency (32MHz)
• Supply voltage range (1.8V ~ 3.6V)
• I/O pin count (24)
• Peripheral feature set (I2C, IrDA, LINbus, SPI, UART/USART)
• Data converter specifications (A/D 19x10b/12b; D/A 2x8b)
• Physical package (28-SSOP)

The PIC24F16KM202-I/SS qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction is product status and operating temperature range, which do not affect functional compatibility in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The PIC24F16KM202-I/SS is the direct substitute for the obsolete PIC24F16KM202-E/SS. Both parts maintain identical electrical specifications, memory configurations, and peripheral integration. The substitute part carries Active product status, ensuring continued availability and manufacturing support from Microchip Technology.

The operating temperature range difference (-40°C ~ 85°C for the I/SS variant versus -40°C ~ 125°C for the E/SS variant) must be evaluated against application requirements. Applications operating within the -40°C to 85°C envelope will experience no functional impact. Applications requiring operation above 85°C require thermal analysis and potential design modification.

Both parts are ROHS3 compliant and carry identical REACH and ECCN classifications, supporting equivalent regulatory and export compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can PIC24F16KM202-I/SS directly replace PIC24F16KM202-E/SS in existing designs?

A: Yes, for applications operating within -40°C to 85°C. The electrical specifications, memory architecture, peripheral set, and package are identical. Designs requiring operation above 85°C require thermal evaluation.

Q: What is the significance of the E/SS and I/SS suffixes?

A: The suffix denotes the temperature grade and packaging specification. E/SS indicates the extended temperature variant (to 125°C), while I/SS indicates the industrial temperature variant (to 85°C). Both use 28-SSOP surface mount packaging.

Q: Are there any pin compatibility concerns?

A: No. Both parts use the 28-SSOP package with identical pinout and electrical characteristics. PCB layout and schematic connections require no modification.

Q: What is the inventory status for these parts?

A: PIC24F16KM202-E/SS is obsolete with limited availability. PIC24F16KM202-I/SS is in active production with higher inventory levels, making it the recommended selection for new designs and production continuity.

Q: Do both parts require identical firmware?

A: Yes. The instruction set, memory organization, and peripheral registers are identical. Firmware compiled for one part executes without modification on the other.

Q: Are there compliance or certification differences?

A: No. Both parts carry identical RoHS3, REACH, and ECCN classifications.
