PIC16F871-E/L Equivalent & Substitute Parts

Part Overview

The PIC16F871-E/L is an 8-bit microcontroller from Microchip Technology's PIC® 16F series, featuring 4.6KB FLASH program memory, 128 bytes of RAM, and 64 bytes of EEPROM. This device integrates UART/USART connectivity, PWM, watchdog timer, and brown-out detection in a 44-PLCC surface mount package. The PIC16F871-E/L is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. Direct manufacturer alternatives with identical electrical and mechanical specifications are available to ensure design continuity.

Substitute Part Grouping Explanation

Substitution of the PIC16F871-E/L is determined by strict equivalence across electrical and mechanical parameters. The primary substitute, PIC16F871-I/L, maintains identical specifications for core processor architecture, memory configuration, I/O count, voltage supply range, peripheral set, and physical packaging. Both parts are based on the same base product number (PIC16F871) and share the 44-PLCC surface mount package with identical dimensions (16.59x16.59mm).

The key parameters enabling direct substitution are:

• Core Processor: PIC (8-Bit architecture)
• Program Memory: 4.6KB FLASH (2K x 14)
• RAM: 128 x 8 bytes
• EEPROM: 64 x 8 bytes
• I/O Pins: 33
• Voltage Supply: 4V ~ 5.5V
• Package: 44-PLCC (16.59x16.59)
• Connectivity: UART/USART
• Peripherals: Brown-out Detect/Reset, POR, PWM, WDT

The primary difference between the main part and substitute is the operating temperature range and product status. The PIC16F871-E/L operates from -40°C to 125°C and is obsolete, while the PIC16F871-I/L operates from -40°C to 85°C and maintains active product status.

Parameter Comparison

Engineering Selection Recommendations

The PIC16F871-I/L is a direct electrical and mechanical equivalent to the PIC16F871-E/L for applications operating within the -40°C to 85°C temperature range. Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring equivalent environmental and regulatory compliance.

For applications requiring operation above 85°C, the PIC16F871-E/L extended temperature range (-40°C to 125°C) is necessary. However, given the obsolete status of the PIC16F871-E/L, alternative solutions from the active PIC® 16F product line should be evaluated for new designs or long-term production requirements.

The PIC16F871-I/L is the recommended substitute for standard industrial and commercial temperature range applications, with active product status ensuring ongoing availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can PIC16F871-I/L replace PIC16F871-E/L in all applications?

A: The PIC16F871-I/L is a direct substitute for applications operating within -40°C to 85°C. Applications requiring operation above 85°C must retain the PIC16F871-E/L or identify alternative active products with extended temperature specifications.

Q: Are the physical packages identical?

A: Yes. Both parts use the 44-PLCC surface mount package with identical dimensions (16.59x16.59mm) and 44-LCC J-Lead configuration. PCB layouts and socket compatibility are identical.

Q: What is the difference between the -E/L and -I/L suffixes?

A: The suffix indicates the temperature grade. The -E/L variant operates from -40°C to 125°C (extended industrial), while the -I/L variant operates from -40°C to 85°C (industrial). Both are from Microchip Technology's standard product line.

Q: Are compliance certifications identical?

A: Yes. Both parts are ROHS3 compliant with identical Moisture Sensitivity Level (MSL) ratings of 3 (168 Hours). REACH and ECCN classifications are identical.

Q: Why is PIC16F871-E/L obsolete?

A: The PIC16F871-E/L has been discontinued by Microchip Technology. The PIC16F871-I/L remains in active production and is the recommended source for new inventory.

Q: Are there memory or I/O differences?

A: No. Both parts have identical memory configurations: 4.6KB FLASH program memory, 128 bytes RAM, 64 bytes EEPROM, and 33 I/O pins. All peripheral functions are identical.
