Substitute Part Grouping Explanation

Substitution of the 74FCT163374APVG is determined by the following critical parameters:

• Package Compatibility: 48-BSSOP (0.295", 7.50mm Width) surface mount package
• Logic Function: D-Type register or flip-flop with dual 8-bit elements
• Output Configuration: Tri-state output capability
• Operating Temperature Range: -40°C ~ 85°C minimum
• Compliance Standards: ROHS3 compliance and EAR99 classification

The identified substitute part 74FCT162374CTPVCT from Texas Instruments shares the same package footprint, element count, bit configuration, and operating temperature range. Both components are classified as obsolete products within the 74FCT logic series, ensuring functional and mechanical compatibility for legacy system applications.

Parameter Comparison

Engineering Selection Recommendations

Selection between the 74FCT163374APVG and 74FCT162374CTPVCT is based on supply voltage requirements and product availability:

The 74FCT163374APVG operates at 2.7V ~ 3.6V and is suitable for 3.3V logic systems. The 74FCT162374CTPVCT operates at 4.5V ~ 5.5V, requiring 5V logic system compatibility. Both components maintain ROHS3 compliance and EAR99 classification, meeting regulatory requirements for industrial and commercial applications. The substitute part is available in Tape & Reel packaging, whereas the main part is supplied in bulk format. Both components share identical operating temperature ranges and package footprints, ensuring mechanical and thermal compatibility in legacy system designs.

Frequently Asked Questions (FAQ)

Q: Can the 74FCT162374CTPVCT directly replace the 74FCT163374APVG in a 3.3V system?

A: No. The 74FCT162374CTPVCT requires 4.5V ~ 5.5V supply voltage, while the 74FCT163374APVG operates at 2.7V ~ 3.6V. Direct substitution in a 3.3V system would require voltage level conversion or system redesign.

Q: Are the package footprints identical?

A: Yes. Both components use the 48-BSSOP (0.295", 7.50mm Width) surface mount package, ensuring identical PCB layout compatibility.

Q: What is the difference between a shift register and a flip-flop in this context?

A: The 74FCT163374APVG is classified as a shift register with D-type elements, while the 74FCT162374CTPVCT is classified as a flip-flop with D-type elements. Both contain dual 8-bit elements with tri-state outputs and share the same package and pin count.

Q: Are both components still in production?

A: No. Both the 74FCT163374APVG and 74FCT162374CTPVCT are obsolete products. Substitution decisions should account for available inventory and long-term supply chain considerations.

Q: What does ROHS3 compliance mean for these components?

A: ROHS3 compliance indicates that both components meet Restriction of Hazardous Substances Directive requirements, restricting the use of specific hazardous materials in electrical and electronic equipment.

Q: Does the Tape & Reel packaging of the substitute affect compatibility?

A: No. Tape & Reel is a packaging and delivery format only. The component itself is identical to bulk-packaged versions and functions identically when mounted on a PCB.
