Substitute Part Grouping Explanation

Substitute parts are grouped based on alignment of mandatory electrical and mechanical parameters. These include manufacturer part number, logic type, series, direction, number of elements, number of bits per element, timing, trigger type, supply voltage range, operating temperature, mounting type, package/case and supplier device package, RoHS status, MSL rating, REACH status, and certification information. Only parts that match these provided parameters and packaging requirements are listed as equivalents.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute parts must be based solely on product lifecycle status and regulatory compliance. The CY74FCT191CTSOCT is marked obsolete, while CY74FCT191CTSOC is listed as active and shares all provided RoHS, REACH, ECCN, and environmental certifications. The substitute CY74FCT191CTSOC aligns with all documented electrical and mechanical parameters of the original part.

Frequently Asked Questions (FAQ)

Q1: What parameters must match to qualify as a direct substitute for CY74FCT191CTSOCT?
A1: Electrical specifications, package/case dimensions, mounting type, logic type, series, supply voltage, operating temperature, RoHS compliance, MSL rating, and REACH status must match.

Q2: Is the CY74FCT191CTSOC pin-compatible with CY74FCT191CTSOCT?
A2: The package and supplier device package are both 16-SOIC (0.295", 7.50mm Width), supporting direct mechanical and electrical compatibility based on provided parameters.

Q3: Are there differences in packaging between CY74FCT191CTSOCT and CY74FCT191CTSOC?
A3: CY74FCT191CTSOCT is listed as Tape & Reel (TR), while CY74FCT191CTSOC is provided in Tube packaging. This does not affect component compatibility.

Q4: Why must obsolete components be substituted?
A4: Obsolete status indicates limited future availability. For long-term production and maintenance cycles, an active equivalent such as CY74FCT191CTSOC ensures ongoing supply.

Q5: Does environmental compliance differ between the original and substitute parts?
A5: Both parts are ROHS3 Compliant and REACH Unaffected according to provided information, supporting compliance continuity.
