Substitute Part Grouping Explanation

Substitution eligibility for the PIC18F23K22T-I/ML is determined by strict equivalence across the following critical parameters:

• Manufacturer and Series: Both parts must originate from Microchip Technology and belong to the PIC® XLP™ 18K series
• Core Architecture: 8-bit PIC processor with identical instruction set compatibility
• Memory Configuration: Identical program memory (8KB FLASH), EEPROM (256 x 8), and RAM (512 x 8) specifications
• Operating Frequency: 64MHz clock speed
• Electrical Specifications: Voltage supply range 2.3V ~ 5.5V, operating temperature -40°C ~ 85°C
• Peripheral Set: Identical connectivity (I2C, SPI, UART/USART) and integrated peripherals (Brown-out Detect/Reset, HLVD, POR, PWM, WDT)
• Pin Configuration: 24 I/O pins, 28-pin QFN package with exposed pad
• Compliance: RoHS3 compliant, REACH unaffected status

The primary distinction between the main part and its substitute lies in packaging format: the main part (PIC18F23K22T-I/ML) is supplied in Tape & Reel (TR) format, while the substitute part (PIC18F23K22-I/ML) is supplied in Tube packaging. Both parts are functionally and electrically identical.

Parameter Comparison

Engineering Selection Recommendations

Both the PIC18F23K22T-I/ML and PIC18F23K22-I/ML are active production parts with identical electrical and functional specifications. Selection between these parts should be based on procurement and assembly requirements:

• Tape & Reel (TR) Format: The PIC18F23K22T-I/ML is suitable for high-volume automated assembly operations where reel-fed component handling is standard practice.
• Tube Format: The PIC18F23K22-I/ML is appropriate for lower-volume production runs, manual assembly processes, or applications where tube packaging is preferred for handling and storage.

Both parts maintain full RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment across all applications. The identical MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for either packaging format.

Frequently Asked Questions (FAQ)

Q: Are PIC18F23K22T-I/ML and PIC18F23K22-I/ML functionally interchangeable?

A: Yes. Both parts are electrically and functionally identical. They contain the same processor core, memory configuration, operating frequency, and peripheral set. The only difference is the packaging format: Tape & Reel versus Tube.

Q: What is the significance of the "T" designation in PIC18F23K22T-I/ML?

A: The "T" in the part number indicates Tape & Reel packaging format, which is optimized for automated pick-and-place assembly. The substitute part without the "T" designation uses Tube packaging.

Q: Can I use the Tube-packaged part in place of the Tape & Reel part in my assembly process?

A: Substitution depends on your assembly equipment and process requirements. If your production line is configured for reel-fed components, the Tube-packaged part requires manual feeding or reeling. Conversely, if your process uses manual component placement, the Tube format may be more practical.

Q: Are there any electrical or performance differences between these two parts?

A: No. Both parts share identical electrical specifications, including voltage supply range (2.3V ~ 5.5V), operating temperature range (-40°C ~ 85°C), clock speed (64MHz), and all integrated peripherals.

Q: Do both parts have the same compliance certifications?

A: Yes. Both the PIC18F23K22T-I/ML and PIC18F23K22-I/ML are RoHS3 compliant and REACH unaffected, with identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited).

Q: Which part should I specify for a new design?

A: Selection should be based on your manufacturing process. For automated assembly with reel-fed components, specify the PIC18F23K22T-I/ML. For manual assembly or lower-volume production, the PIC18F23K22-I/ML in Tube format may be more cost-effective.
