Substitute Part Grouping Explanation

Substitution eligibility for the CY74FCT573CTSOCT is determined by strict equivalence across the following critical parameters:

• Logic Type: D-Type Transparent Latch
• Circuit Configuration: 8:8
• Output Type: Tri-State
• Voltage Supply Range: 4.75V ~ 5.25V
• Independent Circuits: 1
• Propagation Delay Time: 2ns
• Output Current Ratings: 32mA (High) / 64mA (Low)
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 20-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts maintain identical electrical specifications and mechanical compatibility. Variations in product status, packaging format (Tube vs. Tape & Reel), and inventory availability do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

For applications currently utilizing the CY74FCT573CTSOCT, the following selection criteria apply based on product status and compliance:

Primary Recommendation: CY74FCT573ATSOCT or CY74FCT573CTSOC. Both parts maintain active product status with Texas Instruments, ensuring long-term availability and supply chain stability. CY74FCT573ATSOCT is available in Tape & Reel packaging suitable for automated assembly processes, while CY74FCT573CTSOC is supplied in Tube packaging. Both are ROHS3 compliant and carry identical electrical and mechanical specifications to the main part.

Secondary Options: CY74FCT373ATSOCT and CY74FCT573TSOCT are functionally equivalent but carry discontinued status at DiGi Electronics, which may impact future procurement availability. These parts remain suitable for immediate replacement applications where existing inventory is available.

All substitute parts are REACH unaffected and classified under ECCN EAR99, maintaining regulatory compliance equivalent to the original component.

Frequently Asked Questions (FAQ)

Q: Can CY74FCT373ATSOCT be used as a direct replacement for CY74FCT573CTSOCT?

A: Yes. CY74FCT373ATSOCT maintains identical electrical specifications, circuit configuration, output characteristics, and package type. The part number variation reflects internal design differences that do not affect functional interchangeability in 74FCT logic applications.

Q: What is the difference between Tape & Reel and Tube packaging options?

A: Tape & Reel packaging (CY74FCT573ATSOCT) is optimized for automated pick-and-place assembly processes. Tube packaging (CY74FCT573CTSOC) is suitable for manual assembly or lower-volume applications. Both formats contain identical components with equivalent electrical performance.

Q: Are all substitute parts RoHS compliant?

A: Yes. All identified substitute parts are ROHS3 compliant, meeting environmental and hazardous substance restrictions equivalent to the original CY74FCT573CTSOCT component.

Q: Does product status affect electrical performance?

A: No. Product status (Active, Discontinued, or Obsolete) indicates manufacturing and supply availability only. Electrical specifications, performance characteristics, and functional behavior remain identical across all substitute parts regardless of status designation.

Q: Can I mix packaging formats in the same assembly?

A: Yes. Tape & Reel and Tube packaging formats contain identical components. Mixing formats within a single assembly does not affect circuit performance or reliability, though it may complicate inventory management and procurement workflows.

Q: What is Moisture Sensitivity Level 1?

A: MSL 1 indicates unlimited shelf life without moisture control requirements. Components rated MSL 1 do not require special storage conditions or baking procedures prior to assembly, simplifying handling and inventory management.
