Substitute Part Grouping Explanation

Substitution of the PIC17C762-16E/PT is determined by strict equivalence across core functional parameters: processor architecture (PIC), memory configuration (16KB OTP program memory, 678 bytes RAM), clock speed (16MHz), I/O count (66 pins), connectivity interfaces (I2C, SPI, UART/USART), peripheral set (Brown-out Detect/Reset, POR, PWM, WDT), and package form factor (80-TQFP 12x12).

The primary substitute identified is the PIC17C762-16I/PT, which maintains identical specifications across all functional parameters. The distinction between these parts lies in temperature rating and product status: the -16E variant operates across -40°C to 125°C and is obsolete, while the -16I variant operates across -40°C to 85°C and maintains active product status.

Parameter Comparison

Engineering Selection Recommendations

The PIC17C762-16I/PT serves as the direct functional equivalent to the PIC17C762-16E/PT. Both devices are ROHS3 compliant and carry identical MSL ratings, ensuring compatibility with modern manufacturing and environmental standards.

Selection between these parts depends on application temperature requirements. The -16E variant supports extended operation to 125°C, while the -16I variant operates to 85°C. For applications requiring the full -40°C to 125°C range, the -16E specification must be maintained. For applications operating within -40°C to 85°C, the -16I variant is available with active product status and current supply chain support.

Frequently Asked Questions (FAQ)

Q: Can the PIC17C762-16I/PT replace the PIC17C762-16E/PT in all applications?

A: Functional replacement is possible when the application operating temperature does not exceed 85°C. The -16I variant maintains identical core specifications, memory configuration, I/O count, and peripheral set. Applications requiring operation above 85°C require the -16E specification.

Q: What is the significance of the temperature rating difference?

A: The -16E variant (-40°C to 125°C) supports extended high-temperature operation, while the -16I variant (-40°C to 85°C) operates within a narrower range. This difference affects device reliability and performance in thermal environments. Selection must align with actual application temperature requirements.

Q: Are both parts pin-compatible?

A: Yes. Both the PIC17C762-16E/PT and PIC17C762-16I/PT use the 80-TQFP (12x12) package with 66 I/O pins. Pin assignments, signal definitions, and electrical characteristics remain identical, enabling direct board-level substitution.

Q: What is the product status difference, and why does it matter?

A: The -16E is classified as obsolete, indicating Microchip has discontinued active production and support. The -16I maintains active status, ensuring ongoing availability, technical support, and supply chain reliability. For new designs or long-term production, the -16I variant is preferred.

Q: Are there compliance or certification differences?

A: Both parts carry identical ROHS3 compliance and MSL 3 ratings. No compliance or certification differences exist between the variants.
