Key Parameters

Substitute Part Grouping Explanation

Substitution of the PIC16F876AT-E/SS is determined by strict equivalence in the following critical parameters:

• Core processor architecture (PIC 8-bit)
• Program memory capacity (14KB FLASH)
• EEPROM and RAM sizes (256 x 8 and 368 x 8 respectively)
• Operating speed (20MHz)
• Package form factor (28-SSOP)
• Supply voltage compatibility (minimum 4V requirement)
• Surface mount capability
• Temperature range (-40°C to 125°C)
• Compliance certifications (ROHS3, REACH Unaffected, EAR99)

The PIC16F886-E/SS qualifies as a substitute based on these core parameters. Variations in I/O count, analog converter channels, oscillator type, and packaging format (Tube vs. Tape & Reel) do not preclude substitution when the primary functional and electrical specifications align.

Parameter Comparison

Engineering Selection Recommendations

Both the PIC16F876AT-E/SS and PIC16F886-E/SS are active production devices with identical ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Selection between these parts should be based on application-specific requirements:

The PIC16F876AT-E/SS is supplied in Tape & Reel packaging, suitable for high-volume automated assembly operations. The PIC16F886-E/SS is supplied in Tube packaging and offers extended supply voltage range (2V minimum vs. 4V minimum), providing flexibility for low-power applications. Both devices maintain identical core memory specifications and operating temperature range, ensuring functional compatibility in designs where the primary constraints are program memory capacity, EEPROM storage, and processing speed.

Frequently Asked Questions (FAQ)

Q: Can the PIC16F886-E/SS directly replace the PIC16F876AT-E/SS in existing designs?

A: Yes, within the electrical constraints of your application. Both devices share identical program memory (14KB FLASH), EEPROM (256 x 8), RAM (368 x 8), and operating speed (20MHz). The 28-SSOP package form factor is identical. Verify that your circuit's minimum supply voltage requirement does not fall below 4V, as the PIC16F876AT-E/SS specifies a 4V minimum while the PIC16F886-E/SS operates down to 2V.

Q: What are the differences between these two parts?

A: The primary differences are supply voltage range (PIC16F876AT-E/SS: 4V–5.5V; PIC16F886-E/SS: 2V–5.5V), I/O pin count (22 vs. 24), analog converter channels (5 vs. 11), oscillator type (external vs. internal), and packaging format (Tape & Reel vs. Tube). Core memory and processing specifications are identical.

Q: Are there any compatibility concerns with packaging format?

A: Packaging format (Tape & Reel vs. Tube) affects supply chain and assembly logistics but does not impact electrical or mechanical compatibility. Both formats contain the same 28-SSOP component in identical form factor.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PIC16F876AT-E/SS and PIC16F886-E/SS are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes.
