Engineering Selection Recommendations
For new designs and procurement, 74ACT16652DLR is the preferred substitute due to its Active product status and Tape & Reel packaging format, which aligns with modern manufacturing processes and ensures long-term availability.
For applications requiring Tube packaging, 74ACT16651DL is recommended as an alternative, offering Active product status with identical electrical and thermal specifications.
The 74ACT series parts (74ACT16652DL, 74ACT16652DLR, 74ACT16543DL, 74ACT16646DL, 74ACT16651DL) are preferred over 74FCT series equivalents due to their current or Last Time Buy status. The 74FCT series parts (CY74FCT162543CTPVC, CY74FCT162543TPVC, CY74FCT162646ATPVC, CY74FCT162646CTPVC, CY74FCT162652ATPVC, CY74FCT162952BTPVC) are classified as Obsolete and should be used only when existing inventory constraints require their use.
All listed parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly and storage conditions.
Frequently Asked Questions (FAQ)
Q: Can 74ACT16652DLR be used as a direct replacement for 74ACT16652DL?
A: Yes. Both parts are electrically and mechanically identical. The primary difference is packaging format: 74ACT16652DL is supplied in Tube packaging, while 74ACT16652DLR is supplied in Tape & Reel format. The DLR variant is recommended for new designs due to its Active product status.
Q: What is the difference between 74ACT and 74FCT series parts?
A: Both series maintain identical electrical specifications for this product category, including logic type, element count, bit width, output type, current ratings, voltage supply range, and operating temperature. The primary distinction is product lifecycle status: 74ACT parts are either Active or Last Time Buy, while 74FCT parts are Obsolete.
Q: Are the CY74FCT162xxx parts suitable for new production?
A: The CY74FCT162xxx series parts are classified as Obsolete. While they maintain parametric equivalence, they should not be selected for new designs. Use only when existing inventory or legacy system requirements mandate their use.
Q: Does packaging format affect electrical performance?
A: No. Tube and Tape & Reel packaging formats contain identical die and electrical characteristics. Packaging selection is determined by manufacturing process requirements and inventory management practices, not electrical performance.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) rating, ensuring compatibility with standard PCB assembly processes and environmental regulations.
Q: Can I mix packaging formats in the same production run?
A: Yes. Tube and Tape & Reel formats contain identical components and can be used interchangeably within the same assembly process, provided your manufacturing equipment supports both packaging formats.
