Substitute Part Grouping Explanation

Substitution of the PIC24F16KM102-E/SS is determined by strict equivalence across the following critical parameters:

• Core Architecture: PIC 16-bit processor
• Memory Configuration: 16KB FLASH, 1KB RAM, 512 bytes EEPROM
• Operating Frequency: 32MHz
• Supply Voltage Range: 1.8V ~ 3.6V
• I/O Count: 24 pins
• Package Type: 28-SSOP form factor
• Peripheral Set: I2C, IrDA, LINbus, SPI, UART/USART, PWM, WDT, Brown-out Detect/Reset, LVD, POR
• Data Converter Specification: A/D 19x10b/12b

The PIC24F16KM102-I/SS qualifies as a direct substitute based on identical electrical specifications and package compatibility. The primary distinction is the operating temperature range and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The PIC24F16KM102-I/SS is the direct substitute for the obsolete PIC24F16KM102-E/SS. Both devices maintain identical electrical and functional specifications across all critical parameters including memory configuration, processing speed, I/O count, and peripheral integration.

The primary consideration for selection is the operating temperature range. The PIC24F16KM102-E/SS supports -40°C to 125°C operation, while the PIC24F16KM102-I/SS operates from -40°C to 85°C. Applications requiring the extended upper temperature limit of 125°C must evaluate whether the reduced range of the substitute part meets thermal requirements.

The PIC24F16KM102-I/SS carries Active product status with higher inventory availability, providing supply chain advantages for new designs and production continuity. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can the PIC24F16KM102-I/SS be used as a direct replacement for the PIC24F16KM102-E/SS?

A: Yes, the PIC24F16KM102-I/SS is electrically and functionally equivalent. Both devices share identical core architecture, memory configuration, processing speed, I/O count, and peripheral set. The substitute part is pin-compatible and package-compatible in 28-SSOP form factor.

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

A: The suffix designations indicate temperature grade classification. The -E/SS variant supports extended temperature operation from -40°C to 125°C, while the -I/SS variant operates from -40°C to 85°C. The -I/SS designation also reflects the part's current Active product status versus the Obsolete status of the -E/SS variant.

Q: Are there any compatibility concerns when substituting the PIC24F16KM102-I/SS?

A: No compatibility concerns exist for applications operating within the -40°C to 85°C temperature range. The substitute part maintains identical pinout, package dimensions, electrical characteristics, and functional behavior. Applications requiring operation above 85°C must evaluate alternative solutions.

Q: What is the inventory status of each part?

A: The PIC24F16KM102-E/SS (Obsolete) has 718 units in stock. The PIC24F16KM102-I/SS (Active) has 2102 units in stock, providing greater availability for production requirements.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. Both the PIC24F16KM102-E/SS and PIC24F16KM102-I/SS are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
