Substitute Part Grouping Explanation

Substitute parts for the PIC18F8628T-I/PT are identified based on strict equivalence of the following critical parameters:

• Core processor architecture (PIC)
• Core size (8-Bit)
• Operating frequency (40MHz)
• Program memory capacity and type (96KB FLASH)
• EEPROM and RAM configuration (1K x 8 EEPROM, 3.8K x 8 RAM)
• Voltage supply range (4.2V ~ 5.5V)
• I/O pin count (70)
• Package type and dimensions (80-TQFP 12x12)
• Operating temperature range (-40°C ~ 85°C)

The primary difference between the main part and its substitute lies in packaging format: the PIC18F8628T-I/PT is supplied in Tape & Reel (TR) format, while the substitute PIC18F8628-I/PT is supplied in Tray format. Both parts are functionally identical and interchangeable at the component level.

Parameter Comparison

Engineering Selection Recommendations

Both the PIC18F8628T-I/PT and PIC18F8628-I/PT are active production parts from Microchip Technology with identical electrical and functional specifications. Selection between these parts is determined by packaging and supply chain requirements rather than technical performance.

The PIC18F8628T-I/PT in Tape & Reel format is suitable for high-volume automated assembly operations where continuous reel feeding is required. The PIC18F8628-I/PT in Tray format is appropriate for lower-volume production, manual assembly, or applications where reel handling infrastructure is not available.

Both parts maintain RoHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. The identical MSL rating of 3 (168 hours) applies to both variants, requiring equivalent moisture control during storage and handling.

Frequently Asked Questions (FAQ)

Q: Are the PIC18F8628T-I/PT and PIC18F8628-I/PT functionally identical?

A: Yes. Both parts are identical in all electrical, memory, and peripheral specifications. The only difference is the packaging format: Tape & Reel versus Tray.

Q: Can I substitute PIC18F8628-I/PT (Tray) for PIC18F8628T-I/PT (Tape & Reel) in my design?

A: Yes, from a functional and electrical standpoint. The component itself is identical. Substitution feasibility depends on your assembly process capabilities. If your production line supports tray-fed components, the substitution is valid.

Q: What does the "T" in PIC18F8628T-I/PT indicate?

A: The "T" designates Tape & Reel packaging format. The absence of "T" in PIC18F8628-I/PT indicates Tray packaging.

Q: Are there any differences in pin configuration or pinout between these parts?

A: No. Both parts use the identical 80-TQFP (12x12) package with 70 I/O pins in the same configuration.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have an MSL rating of 3, which allows 168 hours of exposure to 85°C and 85% relative humidity before baking is required.

Q: Can I use either part interchangeably on the same PCB?

A: Yes. The PCB footprint, pin assignments, and electrical characteristics are identical. Component selection depends only on your supply chain and assembly process requirements.
