Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74F02D is determined by strict equivalence across the following critical parameters:

• Logic function: 4-channel 2-input NOR gate
• Electrical specifications: 4.5V ~ 5.5V supply voltage, 1mA/20mA output current, 0.8V/2V input logic levels, 5.5ns propagation delay
• Package format: 14-SOIC surface mount
• Compliance certifications: ROHS3, MSL Level 1

The SN74F02DR qualifies as a direct substitute based on identical electrical and functional specifications. The primary distinction is packaging format: SN74F02D is supplied in Tube packaging, while SN74F02DR is supplied in Tape & Reel (TR) format. Both share the same base product number (74F02) and maintain full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SN74F02DR is the direct substitute for the SN74F02D. Both parts maintain identical electrical performance, functional specifications, and compliance certifications. The SN74F02DR carries Active product status, ensuring continued availability and manufacturing support, whereas the SN74F02D is Last Time Buy with limited inventory. For new designs or production continuity, the SN74F02DR is the appropriate selection. Both parts are ROHS3 compliant and carry MSL Level 1 rating, meeting current environmental and reliability standards.

Frequently Asked Questions (FAQ)

Q: Can SN74F02DR replace SN74F02D in existing designs? A: Yes. The SN74F02DR is electrically and functionally identical to the SN74F02D. Both parts operate within the same voltage range (4.5V ~ 5.5V), deliver identical output current specifications (1mA/20mA), and maintain the same propagation delay (5.5ns). The 14-SOIC package dimensions are identical, allowing direct PCB compatibility.

Q: What is the difference between Tube and Tape & Reel packaging? A: Tube packaging (SN74F02D) is used for lower-volume orders and manual assembly processes. Tape & Reel packaging (SN74F02DR) is designed for automated pick-and-place assembly and higher-volume production runs. The electrical and mechanical specifications of the die and package remain identical.

Q: Why is SN74F02D 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 purchase, but no future manufacturing runs are planned. The SN74F02DR, supplied in Tape & Reel format, remains in active production and is the recommended long-term alternative.

Q: Are there any compliance or certification differences between these parts? A: No. Both SN74F02D and SN74F02DR carry identical ROHS3 compliance and MSL Level 1 ratings. Both are REACH Unaffected and classified under ECCN EAR99.

Q: Can I use SN74F02DR in high-volume automated assembly? A: Yes. The Tape & Reel format of the SN74F02DR is specifically designed for automated pick-and-place assembly systems, making it the preferred choice for high-volume production environments.
