SN74AC00NSR NAND Gate IC Equivalent & Substitute Parts

Part Overview

The SN74AC00NSR is a 4-channel 2-input NAND gate logic IC manufactured by Texas Instruments in a 14-SO surface mount package. This component is an active product with full RoHS3 compliance and unlimited moisture sensitivity rating. Alternative part numbers are necessary when the primary manufacturer part is unavailable or when packaging format requirements differ between procurement sources or assembly operations.

Substitute Part Grouping Explanation

Substitution of the SN74AC00NSR is determined by strict equivalence across the following electrical and mechanical parameters:

Logic function: 4-channel 2-input NAND gate configuration
Electrical specifications: Voltage supply range (2V ~ 6V), quiescent current (2 µA max), output current (24mA/24mA), input logic levels, and propagation delay (8ns @ 5V, 50pF)
Operating temperature range: -40°C ~ 85°C
Mounting type: Surface mount
Package type: 14-SOIC form factor
Compliance: RoHS3 and REACH unaffected status
Series designation: 74AC base product number

The 74AC00SCX from onsemi meets all electrical and functional requirements for direct substitution. The primary difference is packaging format: the SN74AC00NSR is supplied in Tape & Reel (TR) format, while the 74AC00SCX is available in Cut Tape (CT) & Digi-Reel® format. Both use identical 14-SOIC package geometry with minor dimensional variations (5.30mm vs 3.90mm width specification) that do not affect PCB footprint compatibility.

Engineering Selection Recommendations

Both the SN74AC00NSR and 74AC00SCX are active products with identical electrical performance and full regulatory compliance. Selection between these parts is determined by procurement and assembly requirements rather than functional capability.

The SN74AC00NSR is appropriate for high-volume automated assembly operations requiring Tape & Reel packaging. The 74AC00SCX is suitable for applications requiring Cut Tape format or when onsemi supply chain availability is preferred. Both parts carry RoHS3 compliance and REACH unaffected status, meeting environmental and regulatory requirements for industrial and commercial applications.

The minor dimensional difference in package width (5.30mm vs 3.90mm) does not affect PCB footprint compatibility, as both use standard 14-SOIC pinout and land pattern specifications.

Frequently Asked Questions (FAQ)

Q: Can the 74AC00SCX directly replace the SN74AC00NSR on a PCB?

A: Yes. Both parts use identical 14-SOIC pinout and electrical specifications. The dimensional variation in package width does not affect PCB footprint compatibility or circuit performance.

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

A: Tape & Reel (TR) format supplies components on continuous carrier tape wound on reels, optimized for high-speed automated pick-and-place assembly. Cut Tape (CT) format supplies components on cut segments of carrier tape, suitable for lower-volume assembly or manual handling. Digi-Reel® is a proprietary reel format. Both formats contain identical components.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts meet identical electrical specifications: 2V ~ 6V supply voltage, 2 µA quiescent current, 24mA output current, and 8ns propagation delay at 5V with 50pF load.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SN74AC00NSR and 74AC00SCX are RoHS3 compliant, REACH unaffected, and carry unlimited moisture sensitivity rating (MSL 1).

Q: What is the operating temperature range for both parts?

A: Both parts operate across -40°C to 85°C, suitable for industrial and commercial temperature environments.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. Electrical equivalence and identical pinout allow direct substitution without circuit redesign or re-qualification.
