Substitute Part Grouping Explanation
Substitution for the CY74FCT162652ATPVC is determined by strict equivalence across the following critical parameters: logic type (non-inverting transceiver), element configuration (2 elements, 8 bits per element), output architecture (3-state), electrical performance (24mA output current capability), supply voltage range (4.5V to 5.5V), operating temperature range (-40°C to 85°C), package form factor (56-BSSOP), and compliance certifications (ROHS3, REACH Unaffected, EAR99).
All identified substitute parts maintain identical specifications across these parameters. Substitutes are grouped into two categories: 74ACT series parts (74ACT16652DL, 74ACT16543DL, 74ACT16646DL, 74ACT16651DL) representing active or last-time-buy status alternatives, and 74FCT series parts (CY74FCT162543CTPVC, CY74FCT162543TPVC, CY74FCT162646ATPVC, CY74FCT162646CTPVC, CY74FCT162952BTPVC) representing obsolete-status equivalents with identical electrical and mechanical characteristics.

Engineering Selection Recommendations
For new designs and ongoing system support, 74ACT16651DL is the preferred substitute due to its active product status and full compliance with ROHS3 and REACH requirements. This part maintains complete electrical and mechanical equivalence to the CY74FCT162652ATPVC while offering extended availability and manufacturer support.
For applications requiring last-time-buy inventory, 74ACT16652DL, 74ACT16543DL, and 74ACT16646DL provide equivalent functionality with confirmed ROHS3 compliance and established supply channels. These parts are suitable for production environments where component continuity is established.
Obsolete 74FCT series alternatives (CY74FCT162543CTPVC, CY74FCT162543TPVC, CY74FCT162646ATPVC, CY74FCT162646CTPVC, CY74FCT162952BTPVC) maintain full parametric equivalence and ROHS3 compliance but carry obsolete status designation. These parts are appropriate for legacy system maintenance where existing inventory exists or for applications where supply chain continuity has been pre-established.
All substitute parts carry identical REACH Unaffected and EAR99 export classification status, ensuring regulatory compliance across international applications.
Frequently Asked Questions (FAQ)
Q: Can 74ACT16651DL directly replace CY74FCT162652ATPVC in existing designs?
A: Yes. The 74ACT16651DL maintains identical electrical specifications (24mA output current, 4.5V to 5.5V supply, -40°C to 85°C operating range), functional architecture (2-element, 8-bit non-inverting transceiver with 3-state output), and package form factor (56-BSSOP). No circuit modifications are required.
Q: What is the difference between 74ACT and 74FCT series parts in this list?
A: Both series provide identical electrical and mechanical performance for these part numbers. The primary distinction is product lifecycle status: 74ACT series parts carry active or last-time-buy designations, while 74FCT series parts are classified as obsolete. Series designation does not affect functional compatibility.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All listed substitute parts carry ROHS3 Compliant certification and REACH Unaffected status, meeting environmental and regulatory requirements for industrial and commercial applications.
Q: Does packaging type affect substitution eligibility?
A: All substitute parts use the 56-BSSOP (0.295", 7.50mm Width) surface mount package. Packaging designation variations (Tube vs. unspecified) reflect supplier packaging format only and do not affect electrical or mechanical compatibility. PCB footprint and mounting procedures remain identical.
Q: Which substitute offers the best long-term availability?
A: 74ACT16651DL carries active product status, indicating ongoing manufacturer support and availability. This part is recommended for new designs requiring extended component lifecycle assurance.
