Substitute Part Grouping Explanation

Substitution for the 74HCT2G02GD,125 is determined by strict equivalence across the following critical parameters:

• Logic Type: NOR Gate (2 channels, 2 inputs per channel)
• Voltage - Supply: 4.5V ~ 5.5V
• Current - Quiescent (Max): 20 µA
• Current - Output High, Low: 4mA, 4mA
• Input Logic Level - Low: 0.8V
• Input Logic Level - High: 2V
• Max Propagation Delay @ V, Max CL: 12ns @ 4.5V, 50pF
• Operating Temperature: -40°C ~ 125°C
• Mounting Type: Surface Mount
• Base Product Number: 74HCT2G02
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The 74HCT2G02DC,125 qualifies as a direct substitute based on identical electrical specifications and compliance certifications. The primary difference is the package type: 8-VSSOP versus 8-XFDFN. Both packages are surface mount configurations with compatible pinouts for the 74HCT2G02 base product number.

Parameter Comparison

Engineering Selection Recommendations

The 74HCT2G02DC,125 is the qualified substitute for the obsolete 74HCT2G02GD,125. Both parts maintain identical electrical performance specifications and comply with ROHS3 and REACH requirements. The substitute part carries Active product status, ensuring continued availability and supply chain support.

The primary design consideration is package compatibility. The main part uses 8-XFDFN packaging, while the substitute uses 8-VFSOP packaging. PCB layout modifications are required to accommodate the different package footprints. Both packages are surface mount configurations with equivalent pinout functionality for the 74HCT2G02 logic gate.

Selection of the substitute part is appropriate for applications where package footprint changes can be accommodated in the PCB design. The electrical performance remains unchanged across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can the 74HCT2G02DC,125 be used as a direct pin-for-pin replacement?

A: The 74HCT2G02DC,125 is functionally equivalent with identical electrical specifications. However, the package types differ (8-VFSOP versus 8-XFDFN), requiring PCB footprint modifications. Pin functionality is equivalent across both packages for the 74HCT2G02 base product.

Q: What is the primary reason for substitution?

A: The 74HCT2G02GD,125 is classified as obsolete. The 74HCT2G02DC,125 maintains active product status, providing continued manufacturing availability and supply chain reliability.

Q: Are the electrical specifications identical between the main part and substitute?

A: Yes. Both parts share identical voltage supply ranges (4.5V ~ 5.5V), quiescent current (20 µA), output current (4mA, 4mA), input logic levels, propagation delay (12ns @ 4.5V, 50pF), and operating temperature range (-40°C ~ 125°C).

Q: What compliance certifications apply to both parts?

A: Both the 74HCT2G02GD,125 and 74HCT2G02DC,125 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: What packaging differences exist between these parts?

A: The main part uses 8-XFDFN (2x3) packaging, while the substitute uses 8-VFSOP (0.091", 2.30mm Width) packaging. Both are surface mount configurations. PCB layout redesign is necessary to accommodate the different footprints.
