Key Parameters

Substitute Part Grouping Explanation

Substitution for PIC16C54CT-20E/SS requires equivalence in these key parameters: manufacturer, series, core processor type and size, clock speed, number of I/O pins, program memory size and type, RAM size, supply voltage range, contained peripherals, oscillator type, operating temperature range, mounting type, device package dimensions, RoHS and REACH compliance, ECCN category, and moisture sensitivity level. Only substitute parts meeting these criteria are listed.

Parameter Comparison

Engineering Selection Recommendations

PIC16C54CT-20E/SS is designated obsolete. PIC16C54C-20I/SS is active and meets all listed key parameters apart from a variation in moisture sensitivity level and a reduced maximum operating temperature. Both parts share RoHS and REACH compliance as well as identical ECCN status. The substitute part is suitable for applications within the specified operating temperature and MSL constraints.

Frequently Asked Questions (FAQ)

Q1: What are the essential criteria for substituting PIC16C54CT-20E/SS?
Essential criteria are manufacturer, series, core architecture, speed, I/O count, memory configuration, supply voltage range, peripherals, oscillator type, package, RoHS and REACH status, ECCN, and moisture sensitivity level.

Q2: Are there differences in packaging between the original and substitute parts?
Both main and substitute parts utilize a 20-SSOP (0.209", 5.30mm Width) surface-mount package.

Q3: How does the operating temperature impact substitute selection?
PIC16C54CT-20E/SS supports -40°C ~ 125°C, while PIC16C54C-20I/SS supports -40°C ~ 85°C. Selection depends on application temperature requirements.

Q4: What is the relevance of the moisture sensitivity level (MSL)?
MSL for the main part is 1 (Unlimited), whereas the substitute is MSL 2 (1 Year). This affects handling and storage procedures in manufacturing.

Q5: Are regulatory compliance requirements met by the substitute part?
Both parts are ROHS3 compliant, REACH unaffected, and categorized as ECCN EAR99, satisfying standard electronic component regulatory requirements.
