Substitute Part Grouping Explanation

Substitute parts for the SN74HCS7002QDRQ1 are identified based on strict equivalence across the following critical parameters:

• Logic type and circuit configuration (4-channel NOR gate with 2 inputs per channel)
• Schmitt trigger input feature
• Supply voltage range (2V ~ 6V)
• Quiescent current specification (2 µA maximum)
• Output current capability (7.8mA high and low)
• Propagation delay performance (12ns @ 6V, 50pF)
• Operating temperature range (-40°C ~ 125°C)
• Package type and dimensions (14-SOIC, 0.154" width)
• Automotive grade and AEC-Q100 qualification
• RoHS3 compliance and MSL rating

The SN74HCS02QDRQ1 meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical performance, thermal specifications, and automotive qualification status, making them directly interchangeable in applications requiring NOR gate logic with Schmitt trigger inputs.
