Key Parameters

Substitute Part Grouping Explanation

Substitution of the PIC16LF818T-E/SS is determined by strict equivalence across core electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical areas:

• Core processor architecture (PIC)
• Core size (8-Bit)
• Operating frequency (10MHz)
• Memory configuration (1.75KB FLASH, 128 x 8 EEPROM, 128 x 8 RAM)
• I/O count (16 pins)
• Peripheral feature set (PWM, WDT, brown-out detection, POR)
• Connectivity protocols (I2C, SPI)
• Analog capability (A/D 5x10b)
• Supply voltage range (2V ~ 5.5V)
• Package form factor (20-SSOP)
• Compliance certifications (ROHS3, REACH Unaffected)

The PIC16LF818-I/SS meets all these criteria and qualifies as a direct substitute. Differences in product status (obsolete vs. active) and operating temperature range do not affect functional substitution capability.

Parameter Comparison

Engineering Selection Recommendations

The PIC16LF818-I/SS is the direct substitute for the PIC16LF818T-E/SS. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The substitute part carries active product status, ensuring ongoing availability and manufacturer support compared to the obsolete main part number.

The operating temperature range difference (-40°C ~ 125°C vs. -40°C ~ 85°C) should be evaluated against specific application requirements. If the design operates within the -40°C ~ 85°C window, the substitute part is fully compatible. For applications requiring operation above 85°C, the temperature specification must be confirmed with the system design parameters.

Frequently Asked Questions (FAQ)

Q: Can the PIC16LF818-I/SS replace the PIC16LF818T-E/SS in existing designs?

A: Yes. Both parts share identical core processor architecture, memory configuration, I/O count, peripheral features, and package form factor. The electrical and mechanical specifications are equivalent, enabling direct substitution at the component level.

Q: What is the significance of the different suffixes (-E vs. -I)?

A: The suffix designates the temperature grade. The -E variant supports -40°C ~ 125°C operation, while the -I variant supports -40°C ~ 85°C. Both are valid PIC16LF818 microcontrollers with identical functionality within their respective temperature ranges.

Q: Are there packaging differences between these parts?

A: The main part (PIC16LF818T-E/SS) is supplied in tape format, while the substitute (PIC16LF818-I/SS) is supplied in tube packaging. Both use the 20-SSOP package form factor with identical pin configuration and mechanical dimensions.

Q: Does the obsolete status of the main part affect substitution?

A: No. Product status does not alter electrical or mechanical compatibility. The obsolete designation indicates that the main part is no longer manufactured. The active status of the substitute part ensures continued availability for procurement and support.

Q: Are both parts compliant with current environmental standards?

A: Yes. Both the PIC16LF818T-E/SS and PIC16LF818-I/SS are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
