Substitute Part Grouping Explanation

Substitution of the PIC16LF819T-E/SS is determined by strict equivalence across the following critical parameters:

• Core Architecture: PIC 8-bit processor
• Memory Configuration: 4.6KB FLASH, 256 x 8 EEPROM, 256 x 8 RAM
• Operating Frequency: 10MHz
• Supply Voltage Range: 2V ~ 5.5V
• I/O Count: 16 pins
• Peripheral Set: I2C, SPI, PWM, WDT, brown-out detection
• Package Type: 20-SSOP surface mount
• Data Conversion: 5-channel 10-bit A/D converter

The PIC16LF819-I/SS meets all these criteria and qualifies as a direct substitute. Differences in product status (obsolete vs. active), operating temperature range, and packaging format (tube vs. unspecified) do not affect functional equivalence for component selection purposes.

Parameter Comparison

Engineering Selection Recommendations

The PIC16LF819-I/SS is the qualified substitute for the PIC16LF819T-E/SS based on functional and electrical equivalence. Both devices share identical core architecture, memory configuration, I/O capability, and peripheral functionality. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The primary difference is the operating temperature range: the main part supports -40°C to 125°C, while the substitute supports -40°C to 85°C. Applications requiring operation above 85°C must retain the original part specification. For standard industrial and commercial temperature ranges, the substitute provides equivalent performance.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with modern manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can PIC16LF819-I/SS replace PIC16LF819T-E/SS in all applications?

A: Functional replacement is possible for applications operating within the -40°C to 85°C temperature range. Applications requiring operation above 85°C must use the original part or identify an alternative with extended temperature rating.

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

A: No. Both parts use the 20-SSOP package with identical pin count and I/O configuration. PCB layout and schematic connections remain unchanged.

Q: What is the significance of the product status difference?

A: The main part (PIC16LF819T-E/SS) is obsolete, meaning Microchip no longer manufactures it. The substitute (PIC16LF819-I/SS) is in active production, providing reliable long-term availability for new designs and production runs.

Q: Do memory specifications differ between these parts?

A: No. Both parts contain identical FLASH program memory (4.6KB), EEPROM (256 x 8), and RAM (256 x 8) configurations.

Q: Are there compliance or certification differences?

A: Both parts are ROHS3 compliant with MSL rating 1 (unlimited). No compliance differences exist between the two parts.

Q: What packaging formats are available for the substitute?

A: The PIC16LF819-I/SS is supplied in tube packaging. Confirm packaging requirements with your procurement specification before ordering.
