PIC24F08KA101T-I/SO Equivalent & Substitute Parts

Part Overview

The PIC24F08KA101T-I/SO is a 16-bit microcontroller from Microchip Technology's PIC® XLP™ 24F series, designed for embedded applications requiring low power operation. This device integrates 8KB of Flash program memory, 1.5KB of RAM, and 512 bytes of EEPROM, operating at 32MHz with a supply voltage range of 1.8V to 3.6V. The microcontroller features integrated connectivity options including I2C, IrDA, SPI, and UART/USART interfaces, along with peripheral functions such as brown-out detection, power-on reset, PWM, and watchdog timer.

The PIC24F08KA101T-I/SO is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production, maintenance, and legacy system support.

Substitute Part Grouping Explanation

Substitution of the PIC24F08KA101T-I/SO is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Identical core processor architecture (PIC 16-Bit)
• Matching clock speed (32MHz)
• Identical program memory capacity (8KB FLASH)
• Identical RAM capacity (1.5K x 8)
• Identical EEPROM capacity (512 x 8)
• Matching supply voltage range (1.8V ~ 3.6V)
• Identical I/O count (18 pins)
• Identical connectivity interfaces (I2C, IrDA, SPI, UART/USART)
• Identical peripheral feature set (Brown-out Detect/Reset, POR, PWM, WDT)
• Identical data converter specification (A/D 9x10b)

Mechanical Equivalence Requirements:

• Identical package type (20-SOIC)
• Identical package dimensions (0.295", 7.50mm Width)
• Surface mount mounting type

Compliance Requirements:

• ROHS3 compliance maintained
• Operating temperature range maintained (-40°C ~ 85°C)

The substitute part PIC24F08KA101-I/SO meets all electrical and mechanical equivalence criteria. The primary difference is packaging format (Tube versus Tape & Reel) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The PIC24F08KA101-I/SO is a direct functional equivalent to the PIC24F08KA101T-I/SO. Both devices share identical electrical specifications, memory configurations, peripheral features, and package geometry. The substitute part is currently in active production status, whereas the original part is obsolete.

Selection of the PIC24F08KA101-I/SO is appropriate for applications requiring component replacement or new production runs. Both parts maintain ROHS3 compliance and operate across the identical temperature range (-40°C ~ 85°C).

The primary distinction between the two parts is packaging format and moisture sensitivity level. The main part (PIC24F08KA101T-I/SO) is supplied in Tape & Reel format with MSL 1 (unlimited moisture exposure tolerance), while the substitute (PIC24F08KA101-I/SO) is supplied in Tube format with MSL 3 (168-hour moisture exposure tolerance). These differences do not affect electrical or functional compatibility and are determined by supply chain and storage requirements rather than device performance.

Frequently Asked Questions (FAQ)

Q: Are the PIC24F08KA101T-I/SO and PIC24F08KA101-I/SO electrically identical?

A: Yes. Both devices are electrically identical with matching core processor architecture, clock speed (32MHz), memory configuration (8KB FLASH, 1.5KB RAM, 512 bytes EEPROM), supply voltage range (1.8V ~ 3.6V), I/O count (18), connectivity interfaces (I2C, IrDA, SPI, UART/USART), and peripheral features (brown-out detection, POR, PWM, WDT).

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

A: The differences are limited to packaging format and product status. The PIC24F08KA101T-I/SO is supplied in Tape & Reel format and is obsolete. The PIC24F08KA101-I/SO is supplied in Tube format and is in active production. Additionally, the moisture sensitivity levels differ (MSL 1 versus MSL 3), reflecting different storage and handling requirements.

Q: Can I use the PIC24F08KA101-I/SO as a direct replacement in existing designs?

A: Yes. The substitute part is mechanically and electrically compatible. Both devices use the 20-SOIC package with identical pin configuration and dimensions (0.295", 7.50mm Width). No circuit modifications are required for substitution.

Q: Does the packaging format affect circuit performance?

A: No. Packaging format (Tape & Reel versus Tube) affects only supply chain logistics and component handling. Electrical and functional performance is identical.

Q: What does MSL 3 (168 Hours) mean for the substitute part?

A: Moisture Sensitivity Level 3 indicates the component can tolerate 168 hours of exposure to moisture at specified humidity and temperature conditions before soldering. This is a handling and storage specification that does not affect device performance after assembly.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the PIC24F08KA101T-I/SO and PIC24F08KA101-I/SO are ROHS3 compliant and meet environmental regulatory requirements.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -40°C to 85°C (TA).
