Substitute Part Grouping Explanation

Substitute parts for the 74LVC373APW/AUJ are identified based on strict parametric equivalence across the following critical criteria:

• Logic Type: D-Type Transparent Latch configuration
• Circuit Configuration: 8:8 channel architecture
• Output Type: Tri-State capability
• Voltage Supply Range: 1.2V ~ 3.6V
• Propagation Delay: 3.3ns
• Output Current Ratings: 24mA (High and Low)
• Operating Temperature Range: -40°C ~ 125°C
• Package Type: 20-TSSOP surface mount
• Compliance Standards: ROHS3, REACH Unaffected, EAR99 classification

The 74LVC373APW-Q100J qualifies as a parametric equivalent substitute, maintaining identical electrical specifications and package configuration while incorporating automotive-grade qualification (AEC-Q100) and Nexperia USA Inc. manufacturing.

Parameter Comparison

Engineering Selection Recommendations

Both the 74LVC373APW/AUJ and 74LVC373APW-Q100J maintain Active product status and are ROHS3 compliant with REACH Unaffected classification. The primary distinction is the automotive-grade qualification (AEC-Q100) of the substitute part, which indicates enhanced reliability testing and qualification for automotive applications. Selection between these parts should be based on application requirements: the main part is suitable for general industrial and consumer applications, while the substitute part is qualified for automotive environments where AEC-Q100 certification is required or preferred. Both parts are electrically and mechanically interchangeable within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Are the 74LVC373APW/AUJ and 74LVC373APW-Q100J pin-compatible?

A: Yes. Both parts use the identical 20-TSSOP package with matching pin configurations, enabling direct substitution on PCB layouts without modification.

Q: What is the significance of the AEC-Q100 qualification on the substitute part?

A: AEC-Q100 qualification indicates the part has undergone automotive-grade reliability testing and stress screening. This certification is required for automotive applications but does not alter the electrical or mechanical specifications for non-automotive use.

Q: Can the 74LVC373APW-Q100J be used in place of the 74LVC373APW/AUJ in all applications?

A: Yes. The substitute part maintains identical electrical specifications, voltage supply range, propagation delay, output current ratings, and operating temperature range. It is a direct functional equivalent.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in 20-TSSOP surface mount packages with identical physical dimensions (0.173" width, 4.40mm). Packaging format may differ (Tape & Reel for the substitute), but the component itself is mechanically identical.

Q: What compliance standards apply to both parts?

A: Both parts are ROHS3 compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Both carry MSL Level 1 (Unlimited) moisture sensitivity rating.
