Substitute Part Grouping Explanation

Substitution eligibility for the PIC16LC711T-04E/SS is determined by strict alignment of the following critical parameters:

Core processor architecture (PIC)
Core size (8-Bit)
Operating speed (4MHz)
Program memory capacity and type (1.75KB OTP)
RAM configuration (68 x 8)
Supply voltage range (2.5V ~ 6V)
Peripheral feature set (Brown-out Detect/Reset, PWM, WDT)
I/O count (13)
Data converter specification (A/D 4x8b)
Package type and dimensions (20-SSOP)
Compliance certifications (ROHS3, MSL 1)

Substitute parts must maintain identical or compatible specifications across all these parameters to ensure functional and electrical equivalence within the original application circuit.

Engineering Selection Recommendations

PIC16LC711-04E/SS is the primary substitute for the obsolete PIC16LC711T-04E/SS. Both parts maintain identical electrical specifications, memory configuration, peripheral features, and package dimensions. The PIC16LC711-04E/SS carries active product status and is ROHS3 compliant with verified programmability, making it suitable for direct replacement in applications requiring the full -40°C to 125°C operating temperature range.

PIC16LC711-04I/SS is an alternative substitute with identical core specifications and active product status. This part differs in operating temperature range, supporting -40°C to 85°C (TA) instead of the full -40°C to 125°C range. Selection of this part is appropriate only for applications where the reduced upper temperature limit is acceptable. The PIC16LC711-04I/SS is supplied in tube packaging and maintains ROHS3 compliance and verified programmability.

Both substitute parts are manufactured by Microchip Technology and carry identical compliance certifications (ROHS3, MSL 1, REACH Unaffected, ECCN EAR99, HTSUS 8542.31.0001) as the original part.

Frequently Asked Questions (FAQ)

Q: Can PIC16LC711-04E/SS directly replace PIC16LC711T-04E/SS?

A: Yes. The PIC16LC711-04E/SS is electrically and functionally equivalent to the PIC16LC711T-04E/SS across all specified parameters, including core architecture, memory configuration, peripheral features, I/O count, supply voltage range, and package type. Both support the full -40°C to 125°C operating temperature range.

Q: What is the difference between PIC16LC711-04E/SS and PIC16LC711-04I/SS?

A: The primary difference is operating temperature range. PIC16LC711-04E/SS operates from -40°C to 125°C (TA), while PIC16LC711-04I/SS operates from -40°C to 85°C (TA). All other electrical and functional specifications are identical. PIC16LC711-04I/SS is supplied in tube packaging.

Q: Are these parts pin-compatible?

A: Yes. All three parts use the 20-SSOP package with identical pin configuration and dimensions (0.209", 5.30mm Width).

Q: Do the substitute parts have the same memory specifications?

A: Yes. All parts feature 1.75KB (1K x 14) OTP program memory, 68 x 8 bytes of RAM, and identical peripheral configurations including brown-out detection, PWM, and watchdog timer.

Q: What compliance certifications apply to these substitute parts?

A: Both substitute parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, are REACH Unaffected, and share identical ECCN (EAR99) and HTSUS (8542.31.0001) classifications with the original part.

Q: Which substitute should I select for high-temperature applications?

A: PIC16LC711-04E/SS is the appropriate choice for applications requiring operation up to 125°C. PIC16LC711-04I/SS is limited to 85°C maximum operating temperature and is not suitable for high-temperature environments.
