SN74F00D NAND Gate IC Equivalent & Substitute Parts

Part Overview

The SN74F00D is a 4-channel 2-input NAND gate logic IC manufactured by Texas Instruments in 14-SOIC surface mount packaging. This component is classified as Last Time Buy, indicating discontinued production with limited availability. The SN74F00D operates within the 74F logic family and is designed for digital logic applications requiring NAND gate functionality. Due to its Last Time Buy status and limited inventory, identifying equivalent substitute parts is essential for design continuity and long-term supply chain planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74F00D is determined by strict equivalence across the following critical parameters:

• Logic Function: NAND gate with 4 circuits and 2 inputs per circuit
• Electrical Specifications: Supply voltage range (4.5V ~ 5.5V), output current ratings (1mA high, 20mA low), input logic levels (0.8V low, 2V high), and propagation delay (5ns @ 5V, 50pF)
• Package Compatibility: 14-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm width)
• Environmental & Compliance: Operating temperature range (0°C ~ 70°C), RoHS3 compliance, MSL Level 1, and REACH unaffected status

The SN74F00DR qualifies as a direct substitute based on identical electrical characteristics, package specifications, and compliance certifications. The primary distinction is packaging format: SN74F00D is supplied in Tube packaging, while SN74F00DR is supplied in Tape & Reel (TR) format. Both maintain Active or Last Time Buy product status within the 74F series.

Parameter Comparison

Engineering Selection Recommendations

The SN74F00DR is the direct equivalent substitute for the SN74F00D. Both parts are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications. The SN74F00DR carries Active product status, ensuring continued availability and supply chain stability compared to the Last Time Buy status of the SN74F00D.

Selection between these parts should be based on packaging requirements and procurement logistics. The SN74F00D in Tube packaging is suitable for lower-volume applications or manual assembly processes. The SN74F00DR in Tape & Reel format is optimized for automated pick-and-place assembly and higher-volume production environments.

Both parts satisfy RoHS3 compliance and MSL Level 1 requirements, making them suitable for standard PCB assembly and storage conditions without moisture sensitivity constraints.

Frequently Asked Questions (FAQ)

Q: Can the SN74F00DR be used as a direct replacement for the SN74F00D in existing designs?

A: Yes. The SN74F00DR is electrically and mechanically identical to the SN74F00D. Both parts feature the same 14-SOIC package, identical pin configuration, and equivalent electrical performance. The only difference is the packaging format (Tube versus Tape & Reel).

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging supplies individual components in a plastic tube, typically used for manual assembly or low-volume applications. Tape & Reel packaging supplies components on a continuous reel in embossed tape, optimized for automated assembly equipment. Both formats contain the same component with identical specifications.

Q: Why is the SN74F00D marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part number. Existing inventory may be available, but no new production runs are planned. The SN74F00DR, with Active status, represents the recommended long-term alternative.

Q: Are there any electrical performance differences between SN74F00D and SN74F00DR?

A: No. Both parts operate at identical supply voltages (4.5V ~ 5.5V), output current ratings (1mA high, 20mA low), input logic levels (0.8V low, 2V high), and propagation delay (5ns @ 5V, 50pF). They are functionally equivalent.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SN74F00D and SN74F00DR are ROHS3 compliant, REACH unaffected, and classified as MSL Level 1 (Unlimited moisture sensitivity). They meet identical environmental and regulatory requirements.

Q: Which part should be selected for new designs?

A: The SN74F00DR should be selected for new designs due to its Active product status and assured long-term availability. It is functionally identical to the SN74F00D and suitable for both manual and automated assembly processes depending on packaging format requirements.
