Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74FCT162373ATPVG are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Compatibility Criteria:

• Logic Type: D-Type Transparent Latch
• Circuit Configuration: 2 Channel 8:8
• Output Type: Tri-State
• Voltage Supply Range: 4.5V ~ 5.5V
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 48-BSSOP surface mount
• Independent Circuits: 2

Secondary Compatibility Considerations:

• Propagation Delay Time (1.5ns to 2ns acceptable range)
• Output Current Ratings (24mA minimum per channel)
• RoHS and REACH compliance status
• Moisture Sensitivity Level

The substitute parts listed maintain electrical equivalence within the specified parameter ranges while offering improved product status or availability compared to the obsolete original part.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

The 74FCT162373ATPVCT and CY74FCT162373ATPVC represent the preferred substitutes for the obsolete 74FCT162373ATPVG. Both parts maintain active product status with Cypress Semiconductor, ensuring long-term availability and supply chain stability. These parts are electrically equivalent with identical circuit configurations, voltage specifications, and operating temperature ranges. The propagation delay increases from 1.5ns to 2ns, which remains within acceptable timing margins for most applications. Both parts feature improved moisture sensitivity levels (MSL 1 vs. MSL 3), reducing handling and storage requirements. REACH compliance is confirmed for both alternatives.

Secondary Substitutes (Obsolete Status with Enhanced Current Ratings):

The CY74FCT16373 series parts (CY74FCT16373ATPVC, CY74FCT16373ATPVCT, CY74FCT16373CTPVC) offer higher output current capabilities (32mA high, 64mA low) compared to the original specification (24mA both directions). These parts maintain full electrical compatibility across all critical parameters including logic type, circuit configuration, voltage range, and operating temperature. The increased current ratings provide design margin for applications requiring higher drive capability. All three variants carry ROHS3 compliance and MSL 1 moisture sensitivity ratings. These parts are classified as obsolete but remain available in inventory.

Compliance Considerations:

All substitute parts maintain REACH unaffected status and EAR99 export classification consistent with the original part. RoHS3 compliance is confirmed for all recommended substitutes. The improved moisture sensitivity levels across all alternatives reduce handling complexity during manufacturing and storage operations.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 74FCT162373ATPVG with 74FCT162373ATPVCT or CY74FCT162373ATPVC?

A: Yes. Both parts are direct electrical equivalents with identical logic type, circuit configuration, output type, voltage supply range, and operating temperature specifications. The 48-BSSOP package dimensions are identical, enabling direct PCB footprint compatibility. The propagation delay increase from 1.5ns to 2ns is within acceptable timing margins for standard applications.

Q: What is the difference between the 74FCT162373 and 74FCT16373 series?

A: The primary difference is output current capability. The 74FCT162373 series provides 24mA output current (both high and low), while the 74FCT16373 series provides 32mA high and 64mA low output current. Both maintain identical logic type, circuit configuration, and package specifications. The 74FCT16373 variants are suitable for applications requiring higher drive capability.

Q: Why do some substitutes have different propagation delay times?

A: The original 74FCT162373ATPVG specifies 1.5ns propagation delay, while substitute parts specify 2ns. This 0.5ns difference reflects manufacturing process variations between manufacturers. For most digital logic applications, this timing difference is negligible and does not affect system functionality.

Q: Are all substitute parts available in the same packaging?

A: Yes. All recommended substitute parts use the 48-BSSOP surface mount package with identical dimensions (0.295" width, 7.50mm). This ensures mechanical compatibility with existing PCB designs without layout modifications.

Q: What does MSL 1 (Unlimited) mean compared to MSL 3 (168 Hours)?

A: Moisture Sensitivity Level (MSL) indicates the maximum time a component can be exposed to ambient conditions before soldering. MSL 3 (168 Hours) limits exposure to 7 days, while MSL 1 (Unlimited) has no time restriction. Substitute parts with MSL 1 provide greater flexibility in manufacturing and storage operations.

Q: Should I choose an active product or obsolete substitute?

A: Active products (74FCT162373ATPVCT and CY74FCT162373ATPVC) are recommended for new designs and long-term production due to guaranteed availability and supply continuity. Obsolete substitutes may be used for legacy system maintenance where existing inventory is available, but long-term sourcing cannot be guaranteed.

Q: Are all substitutes RoHS3 compliant?

A: All recommended substitutes maintain ROHS3 compliance consistent with the original part, ensuring compatibility with environmental regulations and customer requirements.
