SN74F30D NAND Gate IC Equivalent & Substitute Parts

Part Overview

The SN74F30D is a NAND Gate IC manufactured by Texas Instruments, featuring 1 channel with 8 inputs in a 14-SOIC surface mount package. This component is classified as Last Time Buy, indicating discontinued production with limited availability. The SN74F30D remains functional and compliant with current standards, but sourcing alternatives is necessary due to inventory constraints and product lifecycle status. Substitute parts maintain identical electrical and mechanical specifications while offering improved availability through active product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN74F30D is determined by strict equivalence across the following critical parameters:

• Logic Type: NAND Gate (1 channel, 8 inputs)
• Voltage Supply Range: 4.5V ~ 5.5V
• Operating Temperature Range: 0°C ~ 70°C
• Package Type: 14-SOIC surface mount
• Electrical Characteristics: Propagation delay, quiescent current, input/output levels
• Compliance Standards: RoHS3, REACH, ECCN classification

The SN74F30DR qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is packaging format (Tube vs. Tape & Reel) and product status (Last Time Buy vs. Active).

Parameter Comparison

Engineering Selection Recommendations

The SN74F30DR is the direct substitute for the SN74F30D. Both components are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications. The SN74F30DR is preferred for new designs and replenishment orders due to its Active product status, ensuring long-term availability and supply chain stability. Both parts meet ROHS3 compliance and REACH requirements, making them suitable for regulated applications. The packaging format difference (Tube vs. Tape & Reel) does not affect functional compatibility and is determined by procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can the SN74F30DR replace the SN74F30D in existing designs?

A: Yes. The SN74F30DR is electrically and mechanically equivalent to the SN74F30D. All electrical parameters, including supply voltage, propagation delay, input/output levels, and operating temperature range are identical. The 14-SOIC package dimensions are the same, ensuring PCB footprint compatibility.

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

A: Tube packaging (SN74F30D) is used for manual handling and smaller quantity orders. Tape & Reel packaging (SN74F30DR) is designed for automated assembly equipment and high-volume production. The components themselves are identical; the packaging format affects only handling and assembly processes.

Q: Why is the SN74F30D marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part number. Existing inventory is available for a limited time, but no new manufacturing runs are planned. The SN74F30DR, with Active status, represents the current production equivalent and should be used for ongoing projects.

Q: Are there any compliance differences between the two parts?

A: No. Both the SN74F30D and SN74F30DR are ROHS3 compliant, REACH unaffected, and carry the same ECCN and HTSUS classifications. They are functionally equivalent for regulatory and compliance purposes.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: Logic type (NAND Gate, 1 channel, 8 inputs), supply voltage range (4.5V ~ 5.5V), operating temperature (0°C ~ 70°C), package type (14-SOIC), and electrical characteristics (propagation delay, quiescent current, input/output levels). All these parameters are identical between the SN74F30D and SN74F30DR.
