Substitute Part Grouping Explanation

Substitution of the SN74ACT00N-NG is determined by strict equivalence across the following critical parameters:

Functional Parameters (Must Match Exactly):

• Logic Type: NAND Gate
• Number of Circuits: 4
• Number of Inputs: 2 per circuit
• Voltage - Supply: 4.5V ~ 5.5V
• Current - Quiescent (Max): 2 µA
• Current - Output High, Low: 24mA, 24mA
• Input Logic Level - Low: 0.8V
• Input Logic Level - High: 2V
• Max Propagation Delay @ V, Max CL: 9ns @ 5V, 50pF
• Operating Temperature: -40°C ~ 85°C

Substitution Categories:

1. Parametric Equivalent (Same Package Type): SN74ACT00N maintains identical electrical specifications and through-hole 14-DIP packaging. This substitute is suitable for direct replacement in existing PCB designs without layout modification.

2. Manufacturer Recommended Equivalent (Different Package Type): SN74ACT00PWR provides identical electrical specifications but uses surface-mount 14-TSSOP packaging. This substitute requires PCB redesign and is suitable for new designs prioritizing compact form factor and automated assembly.

Parameter Comparison

Engineering Selection Recommendations

For Through-Hole PCB Designs: Select SN74ACT00N as the primary substitute for SN74ACT00N-NG. Both components share identical electrical specifications and 14-DIP through-hole packaging, enabling direct socket replacement without PCB modification. SN74ACT00N maintains active product status, ensuring long-term availability and supply chain continuity. Both components are ROHS3 compliant.

For Surface-Mount PCB Designs or New Designs: Select SN74ACT00PWR as the manufacturer-recommended equivalent. This component provides identical electrical performance within the 14-TSSOP surface-mount package format. SN74ACT00PWR is actively manufactured and distributed, with higher inventory availability. Surface-mount packaging enables automated assembly and reduced PCB footprint. SN74ACT00PWR is ROHS3 compliant with MSL rating of 1 (Unlimited).

Compliance Considerations: All three components (SN74ACT00N-NG, SN74ACT00N, SN74ACT00PWR) are ROHS3 compliant. SN74ACT00N and SN74ACT00PWR carry REACH Unaffected status and EAR99 ECCN classification, consistent with standard logic IC export regulations.

Frequently Asked Questions (FAQ)

Q: Can SN74ACT00N be used as a direct replacement for SN74ACT00N-NG in existing designs?

A: Yes. SN74ACT00N is a parametric equivalent with identical electrical specifications and 14-DIP through-hole packaging. No circuit modifications or PCB redesign are required. The primary difference is product status: SN74ACT00N-NG is obsolete while SN74ACT00N is active.

Q: What is the difference between SN74ACT00N and SN74ACT00PWR?

A: Both components are electrically identical with matching logic specifications, supply voltage, propagation delay, and operating temperature range. The primary difference is packaging: SN74ACT00N uses 14-DIP through-hole mounting, while SN74ACT00PWR uses 14-TSSOP surface-mount packaging. SN74ACT00PWR requires PCB redesign and automated assembly equipment.

Q: Why is SN74ACT00N-NG classified as obsolete?

A: The SN74ACT00N-NG is marked obsolete by the manufacturer. Active equivalents (SN74ACT00N and SN74ACT00PWR) are available to support ongoing production and design requirements.

Q: Are all three parts RoHS compliant?

A: Yes. SN74ACT00N-NG, SN74ACT00N, and SN74ACT00PWR are all ROHS3 compliant, meeting environmental and hazardous substance restrictions.

Q: Which substitute should be selected for new PCB designs?

A: For new designs, SN74ACT00PWR is recommended due to active product status, higher inventory availability, and surface-mount packaging advantages. For designs requiring through-hole components, SN74ACT00N is the appropriate selection.

Q: Do the substitutes maintain the same propagation delay specifications?

A: Yes. All three components (SN74ACT00N-NG, SN74ACT00N, SN74ACT00PWR) specify maximum propagation delay of 9ns at 5V with 50pF load, ensuring timing-critical circuit compatibility.

Q: What is the moisture sensitivity level (MSL) for each part?

A: SN74ACT00N-NG and SN74ACT00N have MSL listed as Not Applicable. SN74ACT00PWR has MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
