Substitute Part Grouping Explanation

Substitution of the CY74FCT823CTSOCT is determined by strict equivalence across the following critical parameters:

• Functional type: D-Type flip-flop with 1 element, 9-bit configuration
• Output characteristics: Tri-state, non-inverted output
• Trigger mechanism: Positive edge triggering
• Package specification: 24-SOIC (0.295", 7.50mm Width) surface mount
• Electrical supply range: 4.75V ~ 5.25V
• Operating temperature range: -40°C ~ 85°C (TA)
• Compliance certifications: ROHS3 Compliant, REACH Unaffected

The CY74FCT823ATSOC meets all substitution criteria as an active product within the same 74FCT series, maintaining identical package, functional configuration, and electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The CY74FCT823ATSOC is the direct substitute for the obsolete CY74FCT823CTSOCT. Both parts maintain identical functional specifications, electrical characteristics, and package geometry. The substitute part carries active product status, ensuring ongoing availability and supply chain continuity. Both components satisfy ROHS3 compliance and REACH regulatory requirements, making them suitable for applications requiring environmental and regulatory adherence. The propagation delay differential (12.5ns versus 20ns) reflects manufacturing variance within the 74FCT series and does not affect functional equivalence for standard logic applications within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can CY74FCT823ATSOC be used as a direct replacement for CY74FCT823CTSOCT?

A: Yes. Both parts are functionally equivalent D-Type flip-flops with identical 9-bit configuration, tri-state non-inverted output, positive edge triggering, 24-SOIC package geometry, and electrical supply specifications. The substitute part is active and available.

Q: What is the significance of the propagation delay difference between the two parts?

A: The main part specifies 12.5ns maximum propagation delay at 5V with 300pF load, while the substitute specifies 20ns under identical conditions. This variance is within normal manufacturing tolerance for the 74FCT series and does not affect functional compatibility in standard logic applications.

Q: Are there packaging differences between these parts?

A: No. Both parts use identical 24-SOIC (0.295", 7.50mm Width) surface mount packaging. PCB layout and assembly processes require no modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CY74FCT823CTSOCT and CY74FCT823ATSOC are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity classification.

Q: Why is the main part listed as obsolete?

A: Product obsolescence reflects end-of-life status from the manufacturer. The CY74FCT823ATSOC maintains active status and provides functional continuity for applications requiring this logic configuration.
