PIC16LF628AT-I/ML Equivalent & Substitute Parts

Part Overview

The PIC16LF628AT-I/ML is an 8-bit microcontroller from Microchip Technology's PIC® 16F series, designed for embedded applications requiring low-power operation and compact form factor. This device features 4.6KB of FLASH program memory, 224 bytes of RAM, and 128 bytes of EEPROM, with integrated peripherals including UART/USART connectivity, PWM, watchdog timer, and brown-out detection. The part is currently in active production status with full RoHS3 compliance and REACH unaffected designation. 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.

Substitute Part Grouping Explanation

Substitution of the PIC16LF628AT-I/ML is determined by strict equivalence across the following critical parameters:

• Manufacturer and Series: Both parts must originate from Microchip Technology and belong to the PIC® 16F series
• Core Architecture: 8-bit PIC core processor with identical instruction set compatibility
• Memory Configuration: Identical program memory (4.6KB FLASH), RAM (224 x 8), and EEPROM (128 x 8) capacity
• Electrical Specifications: Matching voltage supply range (2V ~ 5.5V) and operating temperature range (-40°C ~ 85°C)
• Peripheral Set: Identical connectivity (UART/USART) and integrated peripherals (Brown-out Detect/Reset, POR, PWM, WDT)
• I/O Count: 16 I/O pins
• Package Compatibility: 28-VQFN Exposed Pad (6x6mm) surface mount package
• Compliance: RoHS3 compliance and REACH unaffected status maintained

The PIC16LF628A-I/ML qualifies as a direct substitute based on complete parameter alignment across all electrical, functional, and physical specifications. The only difference is the packaging format (Tube versus Tape & Reel), which does not affect electrical or functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The PIC16LF628A-I/ML is a direct functional and electrical equivalent to the PIC16LF628AT-I/ML. Both devices maintain active product status with identical compliance certifications (RoHS3 compliant, REACH unaffected). The substitution is valid for all applications where the original part is specified, with no functional or electrical limitations introduced by the change.

The only distinction between these parts is the packaging format: the original part is supplied in Tape & Reel format, while the substitute is supplied in Tube format. This difference affects only the procurement and handling process, not the component's electrical characteristics, performance, or reliability. Both packaging formats maintain identical moisture sensitivity levels (MSL 1 - Unlimited) and are suitable for automated assembly processes.

Selection between these parts should be based on packaging availability, supply chain requirements, and procurement preferences rather than technical performance criteria.

Frequently Asked Questions (FAQ)

Q: Are PIC16LF628AT-I/ML and PIC16LF628A-I/ML pin-compatible?

A: Yes. Both devices use the 28-VQFN Exposed Pad package with identical pinout, electrical characteristics, and functional behavior. Direct PCB-level substitution is possible without design modifications.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape suitable for high-volume automated pick-and-place assembly. Tube packaging supplies components in a plastic tube, typically used for lower-volume orders or manual assembly. Both formats contain identical components with no electrical or functional differences.

Q: Can I use PIC16LF628A-I/ML in place of PIC16LF628AT-I/ML in production?

A: Yes. The parts are electrically and functionally identical. Production substitution is valid provided your assembly process can accommodate the Tube packaging format. Verify that your pick-and-place equipment supports tube-fed components if required.

Q: Are the memory specifications identical between these parts?

A: Yes. Both parts feature 4.6KB FLASH program memory (2K x 14), 224 bytes of RAM, and 128 bytes of EEPROM. Memory organization, access timing, and functionality are identical.

Q: Do both parts support the same operating voltage and temperature range?

A: Yes. Both parts operate across 2V to 5.5V supply voltage and -40°C to 85°C ambient temperature range. Electrical performance and reliability specifications are identical across these operating conditions.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance and REACH unaffected status. Moisture sensitivity level (MSL 1 - Unlimited) is identical for both packaging formats.
