Substitute Part Grouping Explanation

Substitution of the PIC18LF44J10T-I/ML with PIC18LF44J10-I/ML is based on strict equivalence across all critical electrical and mechanical parameters. Both parts share identical specifications in the following determinative categories:

Core architecture and processing capability (8-bit PIC processor at 40MHz), memory configuration (16KB FLASH, 1KB RAM), I/O count (32 pins), voltage supply range (2V ~ 3.6V), peripheral feature set (I2C, SPI, UART/USART, Brown-out Detect/Reset, POR, PWM, WDT), analog conversion capability (13-channel 10-bit A/D), operating temperature range (-40°C ~ 85°C), and physical packaging (44-QFN 8x8 with exposed pad).

The primary distinction is product status: the main part is obsolete while the substitute is active, enabling continued sourcing and support.

Parameter Comparison

Engineering Selection Recommendations

The PIC18LF44J10-I/ML is the direct active equivalent for the obsolete PIC18LF44J10T-I/ML. Both parts maintain identical electrical specifications, memory architecture, peripheral configuration, and physical packaging. Selection of the active part ensures compliance with current supply chain requirements and manufacturer support continuity.

Both parts carry ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The MSL rating of 1 (unlimited) indicates no moisture sensitivity constraints during storage and handling.
