PIC16F57T-E/SS Equivalent & Substitute Parts

Part Overview

The PIC16F57T-E/SS is an 8-bit microcontroller from Microchip Technology's PIC® 16F series, designed for embedded applications requiring compact flash memory and low-power operation. This device features 3KB of FLASH program memory, 72 bytes of RAM, and 20 I/O pins, operating across a wide voltage range of 2V to 5.5V. The part is currently in active production status with verified programmability through DiGi-Electronics. Identifying equivalent substitute parts is necessary when the original packaging format (Tape & Reel) is unavailable or when alternative sourcing is required to maintain supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PIC16F57T-E/SS is determined by strict alignment of the following critical parameters:

• Core Processor Architecture: Must be PIC processor family
• Core Size: Must be 8-Bit
• Program Memory: Must be 3KB (2K x 12) FLASH
• RAM Configuration: Must be 72 x 8
• I/O Count: Must be 20 pins
• Operating Voltage Range: Must support 2V ~ 5.5V
• Temperature Range: Must support -40°C ~ 125°C
• Package Type: Must be 28-SSOP form factor
• Mounting Technology: Must be Surface Mount

The primary distinction between the main part and substitute parts lies in packaging format (Tape & Reel versus Tube). All electrical and functional specifications remain identical across the substitute group.

Parameter Comparison

Engineering Selection Recommendations

Both the PIC16F57T-E/SS and PIC16F57-E/SS are active production parts from Microchip Technology with identical electrical specifications and functional capabilities. Selection between these parts should be based on packaging and supply requirements:

• PIC16F57T-E/SS is supplied in Tape & Reel format, suitable for high-volume automated assembly operations
• PIC16F57-E/SS is supplied in Tube packaging, suitable for lower-volume applications or manual assembly processes

Both parts maintain full compliance with ROHS3 and REACH regulations, carry MSL Level 1 (Unlimited moisture sensitivity), and are classified under ECCN EAR99 with HTSUS code 8542.31.0001. Programmability has been verified through DiGi-Electronics for both variants. The choice between these parts does not affect circuit design, firmware compatibility, or functional performance.

Frequently Asked Questions (FAQ)

Q: Are PIC16F57T-E/SS and PIC16F57-E/SS electrically identical?

A: Yes. Both parts share identical core specifications including processor architecture, memory configuration, I/O count, voltage range, temperature range, and peripheral features. The only difference is the packaging format (Tape & Reel versus Tube).

Q: Can I substitute PIC16F57-E/SS for PIC16F57T-E/SS in my design?

A: Yes. Since both parts are identical in electrical and functional specifications and use the same 28-SSOP package form factor, they are direct substitutes. Packaging format does not affect circuit performance or PCB layout.

Q: What is the significance of the packaging difference?

A: Tape & Reel packaging is optimized for high-speed automated pick-and-place assembly, while Tube packaging is typically used for lower-volume manual assembly or component storage. The choice depends on manufacturing process requirements, not circuit functionality.

Q: Are both parts currently available?

A: Both parts maintain active production status. Inventory availability may vary by supplier and time period. Current stock levels should be verified with your component distributor.

Q: Do compliance certifications differ between these parts?

A: No. Both parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, MSL Level 1 (Unlimited), and ECCN EAR99 classification.
