Substitute Part Grouping Explanation

Substitution eligibility for the PIC24F08KM202-E/SS is determined by strict equivalence across the following critical parameters:

• Core Architecture: PIC 16-Bit processor
• Memory Configuration: 8KB FLASH program memory, 2KB RAM, 512 bytes EEPROM
• Clock Speed: 32MHz maximum operating frequency
• I/O Count: 24 I/O pins
• Communication Interfaces: I2C, IrDA, LINbus, SPI, UART/USART
• Peripheral Set: Brown-out Detect/Reset, LVD, POR, PWM, WDT
• Data Conversion: A/D 19x10b/12b; D/A 2x8b
• Package Format: 28-SSOP surface mount
• Supply Voltage Range: 1.8V ~ 3.6V
• Compliance: ROHS3 Compliant, MSL 1

The PIC24F08KM202-I/SS qualifies as a direct substitute based on identical electrical specifications, memory architecture, peripheral configuration, and package format. The primary distinction is product status and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The PIC24F08KM202-I/SS is the direct manufacturer-recommended substitute for the obsolete PIC24F08KM202-E/SS. Both devices maintain identical electrical specifications, memory architecture, peripheral configuration, and 28-SSOP package format, ensuring pin-for-pin and functional compatibility.

The primary distinction is operating temperature range: the -E/SS variant supports -40°C to 125°C, while the -I/SS variant operates from -40°C to 85°C. For applications operating exclusively within the -40°C to 85°C range, the PIC24F08KM202-I/SS provides full functional equivalence with the advantage of Active product status, ensuring continued availability, technical support, and long-term supply chain stability.

Both devices carry ROHS3 compliance and MSL 1 rating, meeting modern environmental and reliability standards. Selection between these variants depends solely on the maximum operating temperature requirement of the target application.

Frequently Asked Questions (FAQ)

Q: Are the PIC24F08KM202-E/SS and PIC24F08KM202-I/SS pin-compatible?

A: Yes. Both devices use the 28-SSOP package with identical pin assignments, memory architecture, and peripheral configuration. Direct substitution is possible without PCB redesign.

Q: What is the key difference between these two part numbers?

A: The primary difference is operating temperature range. The -E/SS supports -40°C to 125°C, while the -I/SS supports -40°C to 85°C. The -E/SS is Obsolete; the -I/SS is Active.

Q: Can I use the PIC24F08KM202-I/SS in an application designed for the -E/SS?

A: Yes, provided your application does not require operation above 85°C. If your design operates exclusively within -40°C to 85°C, the -I/SS is a direct functional equivalent.

Q: Why is the -E/SS marked as Obsolete?

A: Microchip Technology has discontinued the -E/SS variant. The -I/SS remains in active production and is the recommended replacement for new designs and ongoing procurement.

Q: Are there any firmware or software compatibility issues between these variants?

A: No. Both devices share identical core architecture, instruction set, memory organization, and peripheral functionality. Firmware compiled for the -E/SS executes identically on the -I/SS.

Q: What certifications and compliance standards apply to both parts?

A: Both the PIC24F08KM202-E/SS and PIC24F08KM202-I/SS are ROHS3 Compliant, carry MSL 1 rating (Unlimited moisture sensitivity), and are REACH Unaffected.
