PIC16F819-I/PTSL Equivalent & Substitute Parts

Part Overview

The PIC16F819-I/PTSL is an 8-bit microcontroller from Microchip Technology's PIC® 16F series, designed for embedded applications requiring moderate program memory and I/O capability. This device features 4.6KB of FLASH program memory, 256 bytes of EEPROM, and 16 I/O pins, operating at up to 20MHz with an internal oscillator. The part is actively produced and widely used in industrial control, consumer electronics, and IoT applications. Identifying equivalent substitute parts is essential for supply chain continuity, design flexibility, and cost optimization when the primary part becomes unavailable or when alternative packaging options are required.

Substitute Part Grouping Explanation

Substitution of the PIC16F819-I/PTSL is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following areas:

Core Architecture & Memory: The substitute must be a PIC 8-bit microcontroller with 4.6KB FLASH program memory (2K x 14 organization), 256 x 8 EEPROM, and 256 x 8 RAM.

Performance Characteristics: Operating speed must be 20MHz with internal oscillator capability.

I/O & Connectivity: The substitute must provide 16 I/O pins, I2C and SPI connectivity, and identical peripheral support (Brown-out Detect/Reset, POR, PWM, WDT).

Electrical Specifications: Supply voltage range must be 4V ~ 5.5V with A/D converter configuration of 5x10-bit.

Physical & Environmental: The substitute must be rated for -40°C ~ 85°C operating temperature and comply with ROHS3 standards.

Packaging Distinction: The primary difference between the main part and its substitute lies in the packaging designation suffix. The PIC16F819-I/PTSL uses tube packaging, while the PIC16F819-I/P also uses tube packaging but represents a different supplier device package configuration. Both maintain the 18-PDIP physical form factor.

Parameter Comparison

Engineering Selection Recommendations

Both the PIC16F819-I/PTSL and PIC16F819-I/P are active products from Microchip Technology with identical electrical and functional specifications. Selection between these parts should be based on the following factors:

Product Status & Availability: Both parts maintain active production status, ensuring long-term availability and supply chain stability.

Compliance & Certification: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial and consumer applications.

Inventory Considerations: The PIC16F819-I/P maintains significantly higher inventory levels (80,300 pieces) compared to the PIC16F819-I/PTSL (841 pieces), making it the preferred choice for applications requiring immediate availability or high-volume procurement.

Programmability Verification: The PIC16F819-I/P is verified as programmable through DiGi-Electronics, while the PIC16F819-I/PTSL programmability status is not verified. This distinction may be relevant for applications requiring third-party programming services.

Packaging & Handling: Both parts use identical 18-PDIP through-hole packaging with 0.300" (7.62mm) pitch. The tube packaging format is suitable for automated assembly processes and manual handling.

For new designs or high-volume applications, the PIC16F819-I/P is the recommended selection due to superior availability and verified programmability status. For existing designs already qualified with the PIC16F819-I/PTSL, direct substitution with the PIC16F819-I/P presents no functional or compatibility risks.

Frequently Asked Questions (FAQ)

Q: Are the PIC16F819-I/PTSL and PIC16F819-I/P pin-compatible?

A: Yes. Both parts use the 18-PDIP package with identical pin assignments, electrical characteristics, and functional behavior. Direct substitution on PCBs is possible without design modifications.

Q: What is the difference between the "-I/PTSL" and "-I/P" suffixes?

A: The suffix designates the supplier device package and distribution channel. Both represent the same 18-PDIP physical form factor and electrical specifications. The difference is primarily in packaging format and supplier inventory management.

Q: Can I use the PIC16F819-I/P as a drop-in replacement for the PIC16F819-I/PTSL?

A: Yes. All electrical parameters, memory configurations, I/O counts, and operating characteristics are identical. No firmware, PCB layout, or schematic modifications are required.

Q: Are both parts suitable for industrial temperature applications?

A: Yes. Both parts are rated for -40°C ~ 85°C operating temperature, meeting industrial and extended commercial temperature requirements.

Q: Do both parts support the same communication protocols?

A: Yes. Both parts include I2C and SPI connectivity with identical peripheral support including Brown-out Detect/Reset, POR, PWM, and WDT functions.

Q: Which part should I specify for new designs?

A: The PIC16F819-I/P is recommended for new designs due to higher inventory availability and verified programmability status. Both parts are functionally equivalent and will perform identically in your application.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes.
