Substitute Part Grouping Explanation

Substitute parts for the 74FCT162373ATPVCG4 are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents maintain identical electrical specifications including supply voltage (4.5V ~ 5.5V), propagation delay (2ns), and output current (24mA). These parts are functionally interchangeable within the same circuit design without modification. Parametric equivalents include CY74FCT162373ATPVC and CY74FCT162373CTPVC, both from the 74FCT series.

Manufacturer Recommended Substitute (SN74ALVCH162373LR) operates within a different supply voltage range (1.65V ~ 3.6V) and exhibits improved performance characteristics including 1ns propagation delay and reduced output current (12mA). This part requires circuit evaluation for voltage compatibility but offers enhanced speed and lower power consumption.

All substitute parts maintain the same package configuration (48-BSSOP), dual 8:8 channel architecture, tri-state output topology, and operating temperature range (-40°C ~ 85°C).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents): CY74FCT162373ATPVC and CY74FCT162373CTPVC are direct electrical substitutes with identical supply voltage, propagation delay, and output current specifications. CY74FCT162373ATPVC is preferred as it maintains active product status and ROHS3 compliance. Both parts are pin-compatible and require no circuit modification.

For Performance Enhancement: SN74ALVCH162373LR is the manufacturer-recommended substitute offering improved speed (1ns vs. 2ns propagation delay) and reduced power consumption (12mA vs. 24mA output current). This part requires circuit evaluation for voltage compatibility, as it operates within 1.65V ~ 3.6V supply range. Selection of this part is appropriate for designs requiring lower voltage operation or enhanced performance margins.

Compliance Considerations: All recommended substitutes maintain ROHS3 compliance and the same operating temperature range. CY74FCT162373ATPVC and SN74ALVCH162373LR are active products with ongoing manufacturer support, providing superior long-term availability compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can CY74FCT162373ATPVC be used as a direct replacement for 74FCT162373ATPVCG4? A: Yes. CY74FCT162373ATPVC is a parametric equivalent with identical supply voltage (4.5V ~ 5.5V), propagation delay (2ns), output current (24mA), and package configuration (48-BSSOP). No circuit modification is required.

Q: What is the primary difference between the 74FCT and 74ALVCH series substitutes? A: The 74ALVCH series (SN74ALVCH162373LR) operates at lower supply voltages (1.65V ~ 3.6V) compared to the 74FCT series (4.5V ~ 5.5V). The 74ALVCH variant also provides faster propagation delay (1ns vs. 2ns) and lower output current (12mA vs. 24mA). Circuit voltage compatibility must be verified before selection.

Q: Are all substitute parts available in the same package? A: Yes. All substitute parts are available in the 48-BSSOP surface mount package with identical physical dimensions (0.295", 7.50mm Width), ensuring mechanical compatibility with existing PCB layouts.

Q: Which substitute part has the best long-term availability? A: SN74ALVCH162373LR and CY74FCT162373ATPVC both maintain active product status with ongoing manufacturer support. CY74FCT162373CTPVC is classified as obsolete and should not be selected for new designs requiring long-term component availability.

Q: Do all parts meet RoHS3 compliance requirements? A: CY74FCT162373ATPVC, CY74FCT162373CTPVC, and SN74ALVCH162373LR are all ROHS3 compliant, matching the compliance status of the main part 74FCT162373ATPVCG4.
