PIC12F508T-I/MC Equivalent & Substitute Parts

Part Overview

The PIC12F508T-I/MC is an 8-bit microcontroller from Microchip Technology's PIC® 12F series, designed for embedded applications requiring compact form factor and low power consumption. This device features 768B of FLASH program memory, 25 x 8 bytes of RAM, and operates across a wide supply voltage range of 2V to 5.5V. The part is currently in active production status with full RoHS3 compliance and REACH unaffected designation. 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 better suit manufacturing requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PIC12F508T-I/MC is determined by strict equivalence across the following critical parameters: core processor architecture (PIC), core size (8-Bit), operating speed (4MHz), program memory capacity and type (768B FLASH), RAM configuration (25 x 8), supply voltage range (2V ~ 5.5V), I/O count (5 pins), peripheral set (POR, WDT), oscillator type (Internal), operating temperature range (-40°C ~ 85°C), and physical package specification (8-DFN 2x3 with exposed pad). The primary variable distinguishing substitute parts is the distribution packaging format (Tape & Reel versus Tube), which does not affect electrical or functional performance but impacts procurement and assembly workflows. All substitute parts must maintain identical RoHS3 compliance and MSL ratings to ensure manufacturing process compatibility and long-term reliability.

Parameter Comparison

Engineering Selection Recommendations

The PIC12F508-I/MC qualifies as a direct functional equivalent to the PIC12F508T-I/MC based on complete electrical and mechanical parameter alignment. Both parts are manufactured by Microchip Technology, maintain active product status, and carry identical RoHS3 compliance and REACH unaffected certifications. The sole distinction is distribution packaging: the main part is supplied in Tape & Reel format suitable for high-volume automated assembly, while the substitute is supplied in Tube format appropriate for lower-volume or manual assembly workflows. Selection between these parts should be based on procurement requirements, assembly line capabilities, and inventory management practices rather than functional or reliability considerations. Both parts are suitable for applications requiring 8-bit microcontroller functionality within the specified electrical and environmental parameters.

Frequently Asked Questions (FAQ)

Q: Are PIC12F508T-I/MC and PIC12F508-I/MC electrically identical?

A: Yes. Both parts share identical electrical specifications including processor architecture, memory configuration, I/O count, supply voltage range, operating temperature, and peripheral set. They are functionally interchangeable in circuit design and application firmware.

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly equipment. Tube packaging supplies components in plastic tubes, typically used for manual assembly or lower-volume production runs. The physical component itself is identical; only the distribution format differs.

Q: Can I substitute PIC12F508-I/MC for PIC12F508T-I/MC in my design?

A: Yes, provided your assembly process can accommodate Tube packaging format. No circuit design changes, firmware modifications, or PCB layout adjustments are required. The parts are pin-compatible and functionally equivalent.

Q: Do both parts meet the same compliance standards?

A: Yes. Both PIC12F508T-I/MC and PIC12F508-I/MC are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (Unlimited). They meet identical environmental and regulatory requirements.

Q: Which part should I select for high-volume manufacturing?

A: The PIC12F508T-I/MC in Tape & Reel packaging is optimized for high-volume automated assembly. The PIC12F508-I/MC in Tube packaging is more suitable for lower-volume or manual assembly operations.
