The identified substitutes maintain full electrical and mechanical compatibility with the original part number while offering improved availability and active product status.

Parameter Comparison

Engineering Selection Recommendations

PIC16LC771-E/SS is the primary substitute for the obsolete PIC16LC771T-E/SS. This part maintains identical electrical specifications and operating temperature range (-40°C ~ 125°C), ensuring direct functional equivalence. The device carries active product status from Microchip Technology, supporting long-term availability and technical support. Full RoHS3 compliance and REACH unaffected status confirm regulatory alignment with current manufacturing standards.

PIC16LC771-I/SS is an alternative substitute with identical core functionality and electrical parameters. The operating temperature range is restricted to -40°C ~ 85°C, making it suitable for applications not requiring the extended upper temperature specification of 125°C. This part also maintains active product status and full regulatory compliance.

Selection between PIC16LC771-E/SS and PIC16LC771-I/SS depends on application temperature requirements. For systems operating within -40°C to 85°C, either part is acceptable. For applications requiring operation up to 125°C, PIC16LC771-E/SS is the appropriate choice.

Frequently Asked Questions (FAQ)

Q: Can PIC16LC771-E/SS and PIC16LC771-I/SS be used interchangeably with PIC16LC771T-E/SS?

A: Both substitute parts are electrically and mechanically equivalent to the original part. The primary difference is operating temperature range. PIC16LC771-E/SS supports -40°C to 125°C, matching the original specification. PIC16LC771-I/SS operates from -40°C to 85°C. Selection depends on your application's temperature requirements.

Q: What is the difference between the part numbers PIC16LC771T-E/SS and PIC16LC771-E/SS?

A: The "T" designation in PIC16LC771T-E/SS indicates a specific product variant. Both parts share identical electrical specifications, memory configuration, and peripheral functionality. The substitute PIC16LC771-E/SS provides the same core functionality with active product status.

Q: Are the substitute parts available in the same package?

A: Yes. All three parts use the 20-SSOP surface mount package with identical dimensions (0.209" width, 5.30mm). PCB footprints and assembly processes remain unchanged.

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

A: Yes. Both PIC16LC771-E/SS and PIC16LC771-I/SS are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's regulatory status.

Q: Which substitute should I choose for a new design?

A: For new designs, PIC16LC771-E/SS is recommended due to its extended operating temperature range (-40°C to 125°C) and active product status, ensuring long-term support and availability from Microchip Technology.
