74F00SJX NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74F00SJX is a 4-channel 2-input NAND gate logic IC manufactured by onsemi in a 14-SOP surface mount package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity. The 74F00 series represents a standard logic function with consistent electrical characteristics across qualified manufacturers, enabling direct substitution based on matching electrical parameters and package compatibility.

Substitute Part Grouping Explanation

Substitution of the 74F00SJX is determined by strict equivalence across the following parameters: logic type (NAND Gate), number of circuits (4), number of inputs (2), supply voltage range (4.5V ~ 5.5V), output current specifications (1mA high, 20mA low), input logic levels (0.8V low, 2V high), propagation delay (5ns @ 5V, 50pF), and operating temperature range (0°C ~ 70°C). All qualified substitutes maintain these electrical characteristics. Package form factor variations (14-SOP, 14-SOIC, 14-SO) are permitted where mechanical constraints allow, as these represent equivalent surface mount configurations for the same die functionality. Substitutes are categorized by product status and packaging format to support procurement flexibility.

Engineering Selection Recommendations

SN74F00DR (Texas Instruments) is the primary substitute for new designs and production. This part maintains active product status with full RoHS3 compliance and is available in Tape & Reel packaging suitable for automated assembly. The 14-SOIC (0.154", 3.90mm Width) package represents a compact form factor compatible with standard PCB layouts.

SN74F00NSR (Texas Instruments) serves as an alternative substitute with active product status and RoHS3 compliance. This part is packaged in Tape & Reel format and features a 14-SOIC (0.209", 5.30mm Width) package matching the original 74F00SJX physical dimensions, providing direct mechanical compatibility for board redesigns.

SN74F00D (Texas Instruments) is available as a secondary option with Last Time Buy status. This part is supplied in Tube packaging and maintains RoHS3 compliance. Selection of this part should account for its transitional product status.

All three substitutes meet the electrical and environmental requirements of the 74F00SJX and are qualified for direct functional replacement in 74F series logic applications.

Frequently Asked Questions (FAQ)

Q: Can SN74F00DR replace 74F00SJX directly? A: Yes. SN74F00DR is electrically equivalent across all specified parameters: logic type, circuit count, input count, supply voltage, output current, input logic levels, propagation delay, and operating temperature. The 14-SOIC package is mechanically compatible with standard surface mount assembly processes.

Q: What is the difference between SN74F00D and SN74F00DR? A: Both parts are electrically identical. The primary difference is packaging format: SN74F00D is supplied in Tube packaging, while SN74F00DR is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated pick-and-place assembly. SN74F00DR also maintains active product status, whereas SN74F00D is Last Time Buy.

Q: Are there package size differences between the substitutes? A: Yes. SN74F00D and SN74F00DR use 14-SOIC (0.154", 3.90mm Width), while SN74F00NSR uses 14-SOIC (0.209", 5.30mm Width), matching the original 74F00SJX dimensions. Both package sizes are standard 14-pin SOIC configurations. PCB layout compatibility depends on the specific footprint used in your design.

Q: Do all substitutes meet RoHS compliance? A: SN74F00D, SN74F00DR, and SN74F00NSR are all RoHS3 compliant. The original 74F00SJX is REACH Unaffected. All parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements.

Q: Which substitute should I select for new production? A: SN74F00DR is recommended for new designs due to its active product status, RoHS3 compliance, and Tape & Reel packaging optimized for automated assembly. If your PCB footprint requires the larger 14-SOIC (0.209", 5.30mm Width) package, select SN74F00NSR.
