Substitute Part Grouping Explanation

Substitute parts for the CY74FCT16823CTPVC are qualified based on the following critical parameters:

Functional Equivalence: All substitute parts must be dual 9-bit D-type flip-flops with positive edge triggering, tri-state non-inverted outputs, and master reset functionality.

Package Compatibility: All substitutes must use the 56-BSSOP (0.295", 7.50mm Width) surface mount package to ensure PCB footprint compatibility without redesign.

Electrical Characteristics: Substitutes must maintain compatible voltage supply ranges, output drive capabilities, and propagation delay specifications within acceptable operating margins for the target application.

Compliance & Certification: All substitutes must meet ROHS3 compliance and REACH unaffected status to satisfy regulatory requirements.

Two substitute parts meet these criteria:

1. SN74ALVCH16823DLR (Texas Instruments, 74ALVCH series, Active status) — Manufacturer-recommended substitute with enhanced performance characteristics and lower power consumption.

2. 74FCT162823CTPVG8 (Renesas Electronics Corporation, 74FCT series, Active status) — Direct series equivalent with maintained voltage supply range and propagation delay specifications.

Parameter Comparison

Engineering Selection Recommendations

SN74ALVCH16823DLR is the manufacturer-recommended substitute and carries active product status, ensuring long-term availability and supply chain stability. This part is suitable for new designs or redesigns where voltage supply flexibility is acceptable. The 74ALVCH series operates at lower supply voltages (1.65V ~ 3.6V) compared to the original 74FCT series, offering reduced power consumption and improved propagation delay performance. MSL rating of 1 (Unlimited) provides superior moisture handling characteristics.

74FCT162823CTPVG8 maintains the original 74FCT series voltage supply range (4.5V ~ 5.5V) and quiescent current specifications, making it the direct electrical equivalent for applications requiring strict adherence to the original supply voltage parameters. This part is manufactured by Renesas Electronics Corporation and carries active product status. The MSL rating of 3 (168 Hours) requires standard moisture control during storage and handling.

Both substitutes are ROHS3 compliant and REACH unaffected, meeting regulatory compliance requirements equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can SN74ALVCH16823DLR be used as a direct replacement for CY74FCT16823CTPVC without circuit modifications?

A: SN74ALVCH16823DLR is functionally equivalent in logic operation and package footprint. However, it operates at a different voltage supply range (1.65V ~ 3.6V versus 4.5V ~ 5.5V). Circuit modifications to the power supply or voltage regulation may be required depending on the application's power distribution architecture.

Q: What is the primary advantage of 74FCT162823CTPVG8 over SN74ALVCH16823DLR?

A: 74FCT162823CTPVG8 maintains the original 74FCT series voltage supply range and quiescent current specifications, eliminating the need for circuit modifications in systems designed for 5V operation. It is the preferred choice for direct replacement in existing 5V logic systems.

Q: Are both substitute parts available in the same packaging format?

A: Yes. Both SN74ALVCH16823DLR and 74FCT162823CTPVG8 use the 56-BSSOP (0.295", 7.50mm Width) surface mount package, ensuring identical PCB footprint compatibility without layout redesign.

Q: What does MSL rating indicate, and why does it differ between substitutes?

A: Moisture Sensitivity Level (MSL) indicates the maximum time a component can be exposed to ambient conditions (typically 30°C, 85% relative humidity) before soldering. MSL 1 (Unlimited) allows indefinite storage without moisture control. MSL 3 (168 Hours) requires moisture control and baking procedures if storage exceeds 168 hours. Both ratings are acceptable; MSL 3 requires standard moisture management practices.

Q: Can these parts be used interchangeably in the same PCB assembly?

A: Both parts share identical package geometry and pin configuration, allowing PCB-level interchangeability. However, voltage supply compatibility must be verified. SN74ALVCH16823DLR requires 1.65V ~ 3.6V supply, while 74FCT162823CTPVG8 requires 4.5V ~ 5.5V supply. Select the substitute matching your system's power supply voltage.
