Substitute Part Grouping Explanation

Substitution for the 74FCT2373CTQG8 is determined by strict equivalence across the following critical parameters:

• Logic Type: D-Type Transparent Latch
• Circuit Configuration: 8:8
• Output Type: Tri-State
• Voltage Supply Range: 4.75V ~ 5.25V
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 20-SSOP form factor
• Propagation Delay Time: 2ns
• Independent Circuits: 1 channel

Substitute parts must maintain identical functional specifications and package compatibility to ensure direct replacement capability without circuit redesign. Output current ratings may vary within acceptable engineering tolerances for the application.

Parameter Comparison

Engineering Selection Recommendations

The 74FCT2373ATQG8 serves as the primary parametric equivalent to the 74FCT2373CTQG8. Both parts are manufactured by Renesas Electronics Corporation with identical electrical specifications and package configuration. The 74FCT2373ATQG8 maintains Active product status, ensuring continued availability and supply chain support compared to the Last Time Buy status of the original part.

The CY74FCT373ATQCT, manufactured by Texas Instruments, provides an alternative substitute with enhanced output current capability (32mA high, 64mA low versus 15mA/12mA). This part maintains all critical functional parameters including logic type, circuit configuration, voltage supply range, propagation delay, and operating temperature range. The CY74FCT373ATQCT carries Moisture Sensitivity Level 2 with a 1-year shelf life requirement, compared to MSL 1 (Unlimited) for the Renesas alternatives. All three parts maintain ROHS3 compliance and REACH Unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the 74FCT2373ATQG8 be used as a direct replacement for the 74FCT2373CTQG8?

A: Yes. The 74FCT2373ATQG8 is a parametric equivalent with identical electrical specifications, circuit configuration, and package type. The primary difference is product status: the ATQG8 variant is Active while the CTQG8 is Last Time Buy.

Q: What are the differences between the Renesas and Texas Instruments alternatives?

A: The CY74FCT373ATQCT (Texas Instruments) provides higher output current ratings (32mA/64mA versus 15mA/12mA) and operates under Moisture Sensitivity Level 2 with a 1-year shelf life requirement, compared to MSL 1 (Unlimited) for Renesas parts. All other electrical and functional parameters remain equivalent.

Q: Are there packaging format differences between these substitutes?

A: The 74FCT2373CTQG8 and 74FCT2373ATQG8 are supplied in Tape & Reel format. The CY74FCT373ATQCT is supplied in Cut Tape format. All three use the same 20-SSOP package type suitable for surface mount assembly.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant and REACH Unaffected. The primary compliance difference is Moisture Sensitivity Level: Renesas parts are MSL 1 (Unlimited storage), while the Texas Instruments part is MSL 2 (1-year shelf life).

Q: Which substitute should be selected for new designs?

A: For new designs requiring standard output current levels, the 74FCT2373ATQG8 is recommended due to Active product status and unlimited moisture sensitivity. For applications requiring higher output current capability, the CY74FCT373ATQCT provides enhanced drive capability with equivalent functional performance.
