Substitute Part Grouping Explanation

The PIC16F722A-I/SO qualifies as a direct substitute for the PIC16F722AT-I/SO based on the following criteria:

Identical Electrical Specifications:

• Core processor architecture (PIC 8-bit)
• Operating frequency (20MHz)
• Program memory capacity and type (4.6KB FLASH)
• RAM configuration (128 x 8)
• Supply voltage range (1.8V ~ 5.5V)
• Peripheral set (I2C, SPI, UART/USART, Brown-out Detect/Reset, POR, PWM, WDT)
• I/O count (25 pins)
• Data converter specifications (A/D 11x8b)

Identical Physical Specifications:

• Package format (28-SOIC)
• Package dimensions (0.295", 7.50mm Width)
• Mounting type (Surface Mount)

Compliance Alignment:

• RoHS3 Compliant status maintained
• REACH Unaffected classification
• Same HTSUS code (8542.31.0001)

The substitution is based on manufacturing revision differences (A-variant) and packaging format variation (Tube vs. Cut Tape), not functional or electrical divergence.

Parameter Comparison

Engineering Selection Recommendations

Both the PIC16F722AT-I/SO and PIC16F722A-I/SO are active production devices from Microchip Technology with identical electrical and functional specifications. Selection between these parts should be based on the following factors:

Packaging and Logistics: The PIC16F722AT-I/SO is supplied in Cut Tape (CT) and Digi-Reel® format, suitable for high-volume automated assembly operations. The PIC16F722A-I/SO is supplied in Tube packaging, appropriate for lower-volume applications or manual assembly workflows.

Moisture Sensitivity: The PIC16F722A-I/SO features MSL 1 (Unlimited shelf life), providing superior moisture tolerance compared to the PIC16F722AT-I/SO with MSL 3 (168-hour limit). This distinction is relevant for long-term storage or applications in high-humidity environments.

Compliance and Regulatory: Both parts maintain identical RoHS3 and REACH compliance status, ensuring regulatory alignment across supply chain alternatives.

Inventory Availability: The PIC16F722AT-I/SO has 61,100 units in stock, while the PIC16F722A-I/SO has 16,200 units available. Procurement decisions should account for lead time and volume requirements.

Frequently Asked Questions (FAQ)

Q: Are the PIC16F722AT-I/SO and PIC16F722A-I/SO functionally identical?

A: Yes. Both devices share identical core processor architecture, memory configuration, operating frequency, peripheral set, and I/O specifications. The differences are limited to manufacturing revision designation and packaging format.

Q: Can I use PIC16F722A-I/SO in place of PIC16F722AT-I/SO in my circuit design?

A: Yes. The electrical specifications, pin configuration, and functional behavior are identical. No circuit modifications are required for direct substitution.

Q: What is the significance of the MSL rating difference?

A: MSL 3 (PIC16F722AT-I/SO) allows 168 hours of exposure to 85°C and 85% relative humidity before baking is required. MSL 1 (PIC16F722A-I/SO) has unlimited shelf life without moisture sensitivity constraints. For applications with extended storage periods or high-humidity environments, the MSL 1 variant is advantageous.

Q: Which packaging format should I select?

A: Cut Tape (CT) and Digi-Reel® packaging is optimized for automated pick-and-place assembly at high volumes. Tube packaging is suitable for manual assembly or lower-volume production runs. Selection depends on your manufacturing process and volume requirements.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the PIC16F722AT-I/SO and PIC16F722A-I/SO are RoHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic components.

Q: What is the base product number for these parts?

A: Both parts are based on the PIC16F722 core design. The "A" designation in PIC16F722A indicates a manufacturing revision, while the suffix (-I/SO) specifies the temperature grade and package type.
