PIC18F4585T-I/PT Equivalent & Substitute Parts

Part Overview

The PIC18F4585T-I/PT is an 8-bit microcontroller from Microchip Technology's PIC® 18F series, designed for embedded applications requiring moderate processing capability and integrated connectivity. This device features 48KB of FLASH program memory, 3.25KB of RAM, and 1KB of EEPROM, operating at 40MHz with a 44-pin TQFP package. The part is currently in active production status and is ROHS3 compliant. Identifying equivalent substitute parts is necessary when the primary packaging format (Tape & Reel) is unavailable or when alternative sourcing is required while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the PIC18F4585T-I/PT is determined by strict equivalence across all electrical and mechanical parameters. The primary differentiator between the main part and its substitute is the packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute part PIC18F4585-I/PT is supplied in Tray packaging. Both parts share identical core specifications including processor architecture, memory configuration, I/O count, voltage supply range, connectivity options, and thermal operating range. The 44-TQFP (10x10) package footprint remains constant across both variants, ensuring mechanical compatibility in PCB assembly. Substitution is valid when packaging format flexibility is acceptable and electrical performance requirements remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

Both the PIC18F4585T-I/PT and PIC18F4585-I/PT are active production parts from Microchip Technology with identical ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on packaging and supply chain requirements. The Tape & Reel format of the main part is optimized for high-volume automated assembly operations, while the Tray packaging of the substitute part accommodates manual assembly or lower-volume production runs. Both parts maintain equivalent electrical performance, thermal characteristics, and functional capabilities. The choice between these variants does not impact circuit design, firmware compatibility, or system performance.

Frequently Asked Questions (FAQ)

Q: Are the PIC18F4585T-I/PT and PIC18F4585-I/PT electrically identical?

A: Yes. Both parts are manufactured by Microchip Technology and share identical electrical specifications, including processor architecture, memory configuration, I/O count, voltage supply range, operating temperature range, and peripheral functionality.

Q: What is the difference between Tape & Reel and Tray packaging?

A: Tape & Reel packaging supplies components on a continuous carrier tape wound on a reel, optimized for automated pick-and-place assembly. Tray packaging supplies components in static-dissipative trays, suitable for manual handling or lower-volume assembly processes. Both formats contain the same component with identical electrical properties.

Q: Can I use PIC18F4585-I/PT as a direct replacement for PIC18F4585T-I/PT in my design?

A: Yes, provided your assembly process can accommodate Tray packaging. The 44-TQFP (10x10) footprint is identical, and all electrical specifications match. No circuit design changes are required.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 3 (168 Hours) ratings.

Q: What should I consider when selecting between these two packaging formats?

A: Consider your production volume, assembly equipment capabilities, and supply chain logistics. Tape & Reel is standard for high-volume automated assembly. Tray packaging is appropriate for manual assembly, prototyping, or lower-volume production runs.
