Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PIC17LC44T-08I/PT is determined by the following critical parameters:

• Core processor architecture (PIC)
• Core size (8-Bit)
• Program memory capacity (16KB OTP)
• RAM capacity (454 x 8)
• I/O pin count (33)
• Operating voltage range (2.5V ~ 6V)
• Package type (44-TQFP)
• Peripheral set (UART/USART, POR, PWM, WDT)
• Operating temperature range (-40°C ~ 85°C)

The substitute part PIC17LC44-08I/PT maintains identical electrical and mechanical specifications across all critical parameters, with the primary distinction being packaging configuration and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The PIC17LC44-08I/PT serves as a direct functional equivalent to the PIC17LC44T-08I/PT. Both components are manufactured by Microchip Technology and maintain identical electrical specifications, memory architecture, I/O configuration, and peripheral functionality. The substitute part is currently in active production status, whereas the main part is classified as obsolete.

Selection between these parts should be based on:

• Availability requirements: The substitute part maintains higher inventory levels (2300 Pcs vs. 1117 Pcs)
• Product lifecycle considerations: Active status of the substitute part ensures continued manufacturer support
• Packaging requirements: Tray packaging (substitute) versus tube packaging (main part) may influence procurement and assembly processes
• Compliance requirements: Both parts maintain ROHS3 compliance and REACH unaffected status

Frequently Asked Questions (FAQ)

Q: Are PIC17LC44T-08I/PT and PIC17LC44-08I/PT pin-compatible?

A: Yes. Both components utilize the 44-TQFP package with identical pin assignments, I/O configuration (33 pins), and electrical characteristics.

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

A: The primary differences are packaging configuration (tube versus tray) and product status (obsolete versus active). All electrical and functional specifications remain identical.

Q: Can I use PIC17LC44-08I/PT as a direct replacement in existing designs?

A: Yes. The substitute part maintains identical core specifications, memory capacity, operating voltage range, temperature range, and peripheral functionality, enabling direct substitution in PCB layouts and firmware implementations.

Q: Why is the main part classified as obsolete?

A: Product status reflects Microchip Technology's manufacturing and support lifecycle. The substitute part's active status indicates ongoing availability and manufacturer support.

Q: Are there any compliance differences between the parts?

A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels (MSL 3, 168 Hours).

Q: What packaging options are available?

A: The main part is supplied in tube packaging, while the substitute part is supplied in tray packaging. Both utilize the same 44-TQFP (10x10) case.
