Substitute Part Grouping Explanation

Substitution of the PIC24F08KM101-E/P is determined by strict equivalence across the following critical parameters:

• Core Architecture: PIC 16-Bit processor
• Memory Configuration: 8KB FLASH program memory, 1KB RAM, 512 bytes EEPROM
• Operating Frequency: 32MHz
• Supply Voltage Range: 1.8V ~ 3.6V
• I/O Count: 18 pins
• Communication Interfaces: I2C, IrDA, LINbus, SPI, UART/USART
• Peripheral Set: Brown-out Detect/Reset, LVD, POR, PWM, WDT
• Package Format: 20-DIP (0.300", 7.62mm)
• Mounting Technology: Through Hole

The substitute part PIC24F08KM101-I/P maintains identical electrical specifications and pinout compatibility. The primary distinction lies in product status and operating temperature range, which are documented in the parameter comparison table below.

Engineering Selection Recommendations

The PIC24F08KM101-I/P serves as the direct substitute for the obsolete PIC24F08KM101-E/P. Both devices are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The substitute part maintains active product status with Microchip Technology, ensuring continued availability and technical support.

The primary consideration for selection is the operating temperature range. The main part (PIC24F08KM101-E/P) operates across -40°C to 125°C, while the substitute (PIC24F08KM101-I/P) operates across -40°C to 85°C. Applications requiring operation above 85°C must retain the original part specification or identify alternative solutions outside this product family.

All other electrical, functional, and mechanical parameters are identical, including pinout, memory configuration, communication interfaces, and peripheral functionality. Pin-for-pin compatibility is confirmed across both variants.

Frequently Asked Questions (FAQ)

Q: Are PIC24F08KM101-E/P and PIC24F08KM101-I/P pin-compatible?

A: Yes. Both devices use the 20-DIP (0.300", 7.62mm) package with identical pinout and electrical characteristics. Direct socket substitution is possible without circuit modification.

Q: What is the key difference between these two parts?

A: The primary difference is operating temperature range. The PIC24F08KM101-E/P operates from -40°C to 125°C, while the PIC24F08KM101-I/P operates from -40°C to 85°C. The substitute part is currently in active production status, whereas the original is obsolete.

Q: Can I use PIC24F08KM101-I/P in applications designed for PIC24F08KM101-E/P?

A: Yes, provided your application does not require operation above 85°C. If your system operates within the -40°C to 85°C range, the substitute part is functionally and electrically equivalent.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 1 - Unlimited). Regulatory and environmental certifications are equivalent.

Q: What packaging options are available?

A: The main part (PIC24F08KM101-E/P) is supplied in standard packaging. The substitute part (PIC24F08KM101-I/P) is supplied in tube packaging. Both use the same 20-PDIP physical format suitable for through-hole assembly.

Q: Why is the original part listed as obsolete?

A: Product obsolescence is determined by the manufacturer. The substitute part (PIC24F08KM101-I/P) remains in active production and is the recommended source for new inventory and ongoing system support.
