Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped strictly based on matching the following technical and compliance parameters: microcontroller series, core type and size, speed, program memory size and type, RAM size, supply voltage, connectivity, peripherals, data converter specification, package type and dimensions, mounting type, RoHS and REACH compliance, MSL rating, and ECCN/HTSUS codes. Only substitutes meeting all specified criteria are included.

Parameter Comparison

Engineering Selection Recommendations

The main part, PIC16C72AT-20E/SS, is obsolete, while the substitute PIC16C72A-20I/SS is active. Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL level 1. ECCN and HTSUS codes are consistent between models. For applications requiring ongoing regulatory conformity and uninterrupted part status, selection of an active and compliant substitute part such as PIC16C72A-20I/SS aligns with the status and certification requirements.

Frequently Asked Questions (FAQ)

Q1: What are the key parameters used for substituting PIC16C72AT-20E/SS?
A1: Substitution is based strictly on series, core processor and size, speed, program memory size and type, RAM size, supply voltage, connectivity, peripherals, data converter specification, package dimensions and type, mounting type, compliance status, and classification codes.

Q2: Are there significant differences in package or mounting between PIC16C72AT-20E/SS and PIC16C72A-20I/SS?
A2: Both models use the 28-SSOP surface mount package with identical dimensions.

Q3: Is there any impact on operating temperature when substituting with PIC16C72A-20I/SS?
