PIC16F628AT-E/SO Equivalent & Substitute Parts

Part Overview

The PIC16F628AT-E/SO is an 8-bit microcontroller from Microchip Technology's PIC® 16F series, designed for embedded applications requiring compact flash memory and integrated peripherals. This device features 4.6KB of FLASH program memory, 224 bytes of RAM, and 128 bytes of EEPROM, operating across a wide voltage range of 3V to 5.5V. The part is currently in active production status with verified programmability through DiGi-Electronics. Identifying equivalent substitute parts is essential for supply chain continuity, inventory optimization, and design flexibility when the primary part number becomes unavailable or when alternative packaging formats are required.

Substitute Part Grouping Explanation

Substitution eligibility for the PIC16F628AT-E/SO is determined by strict equivalence across the following critical parameters: core processor architecture (PIC), core size (8-Bit), execution speed (20MHz), program memory capacity (4.6KB FLASH), EEPROM size (128 x 8), RAM allocation (224 x 8), I/O pin count (16), supply voltage range (3V ~ 5.5V), operating temperature range (-40°C ~ 125°C), package type (18-SOIC), and peripheral feature set (UART/USART, Brown-out Detect/Reset, POR, PWM, WDT).

The PIC16F628A-E/SO qualifies as a direct substitute because it maintains identical electrical specifications, memory configuration, I/O architecture, and peripheral functionality. The only variance is the packaging format (Tube versus Tape & Reel), which does not affect electrical or functional compatibility. Both parts share the same base product number (PIC16F628) and are manufactured by Microchip Technology under active product status.

Parameter Comparison

Engineering Selection Recommendations

Both the PIC16F628AT-E/SO and PIC16F628A-E/SO are active production devices manufactured by Microchip Technology with identical ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Selection between these parts should be based on packaging requirements and supply chain availability. The main part (PIC16F628AT-E/SO) is supplied in Tape & Reel format, suitable for high-volume automated assembly operations. The substitute part (PIC16F628A-E/SO) is supplied in Tube packaging, appropriate for lower-volume applications or manual assembly processes. Both parts carry MSL Level 1 (Unlimited) moisture sensitivity rating, indicating no special storage or handling precautions are required. Electrical and functional compatibility is complete, with no design modifications necessary when transitioning between these part numbers.

Frequently Asked Questions (FAQ)

Q: Can PIC16F628A-E/SO be used as a direct replacement for PIC16F628AT-E/SO in production designs?

A: Yes. Both parts are electrically and functionally identical. The only difference is packaging format (Tube versus Tape & Reel). If your assembly process accommodates tube packaging, this substitute is fully compatible without design changes.

Q: Are there any firmware or software compatibility issues between these two part numbers?

A: No. Both parts share identical core processor architecture, memory configuration, and peripheral feature sets. Firmware compiled for one part executes identically on the other.

Q: What is the significance of the packaging difference between Tape & Reel and Tube formats?

A: Tape & Reel packaging is optimized for high-speed automated pick-and-place assembly equipment. Tube packaging is used for manual assembly, lower-volume production, or component distribution. The electrical specifications and component functionality remain unchanged.

Q: Do both parts meet the same compliance and certification standards?

A: Yes. Both PIC16F628AT-E/SO and PIC16F628A-E/SO are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both carry identical moisture sensitivity levels and export classifications.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -40°C to 125°C (TA), supporting industrial and extended temperature applications without derating.

Q: Are there any supply voltage or power consumption differences?

A: No. Both parts operate across the identical 3V to 5.5V supply range with no variations in power characteristics or voltage regulation requirements.
