Substitute Part Grouping Explanation

Substitute parts for the PIC16F876AT-I/ML are identified based on strict equivalence of core functional parameters: 8-bit core processor, 20MHz speed, 14KB FLASH program memory, 256 x 8 EEPROM, 368 x 8 RAM, and 28-VQFN surface mount packaging. The substitution logic recognizes two categories:

Direct Equivalent (PIC16F876A-I/ML): Maintains identical electrical specifications, memory configuration, and I/O count (22 pins). Differs only in packaging format (Tube vs. unspecified in main part).

Manufacturer Recommended Substitute (PIC16F886-I/ML): Shares core memory architecture and package form factor but introduces controlled parameter variations: expanded I/O capability (24 pins vs. 22), extended voltage supply range (2V ~ 5.5V vs. 4V ~ 5.5V), increased analog input channels (11x10b vs. 5x10b), and internal oscillator support. These enhancements provide functional superset capability within the same physical package.

Parameter Comparison

Engineering Selection Recommendations

PIC16F876A-I/ML is selected as the direct equivalent when inventory or packaging format (Tube) is the primary consideration. This part maintains 100% electrical and functional parity with the PIC16F876AT-I/ML, differing only in packaging specification. Both parts carry identical active product status, ROHS3 compliance, and REACH unaffected designation, making this substitution transparent for applications already qualified to the PIC16F876 base product number.

PIC16F886-I/ML is the manufacturer-recommended substitute when design flexibility permits utilization of enhanced capabilities. This part expands the I/O pin count from 22 to 24, extends the minimum supply voltage to 2V, and provides 11 analog input channels versus 5, while maintaining the identical 28-VQFN package footprint and core memory architecture. The addition of internal oscillator support reduces external component requirements. All three parts share identical active product status, compliance certifications, and thermal operating range, supporting direct substitution in applications where the additional I/O and analog resources do not create design conflicts.

Frequently Asked Questions (FAQ)

Q: Can PIC16F876A-I/ML be used as a direct replacement for PIC16F876AT-I/ML?

A: Yes. The PIC16F876A-I/ML maintains identical electrical specifications, memory configuration, I/O count, and package form factor. The only difference is packaging format (Tube). Both parts are based on the same PIC16F876 base product number and carry active product status.

Q: What are the key differences between PIC16F876AT-I/ML and PIC16F886-I/ML?

A: The PIC16F886-I/ML provides four additional I/O pins (24 vs. 22), supports lower minimum supply voltage (2V vs. 4V), includes six additional analog input channels (11 vs. 5), and features internal oscillator capability. Core memory (14KB FLASH, 256B EEPROM, 368B RAM) and package form factor remain identical.

Q: Is the 28-VQFN package identical across all three parts?

A: Yes. All three parts use the 28-VQFN Exposed Pad surface mount package with 6x6mm dimensions, ensuring PCB layout compatibility.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. PIC16F876AT-I/ML, PIC16F876A-I/ML, and PIC16F886-I/ML are all ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can PIC16F886-I/ML be used in applications designed for PIC16F876AT-I/ML?

A: The PIC16F886-I/ML provides a functional superset with additional I/O and analog resources. Substitution is valid when the application design does not conflict with the expanded pin count or lower minimum voltage specification. Firmware compatibility depends on application-specific code requirements.

Q: What is the operating temperature range for all substitute parts?

A: All three parts operate across -40°C to 85°C (TA), supporting identical thermal specifications.
