74F86SJX XOR Logic IC - Equivalent & Substitute Parts

Part Overview

The 74F86SJX is a 4-channel, 2-input XOR (Exclusive OR) logic integrated circuit 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 74F86 series provides standard logic gating functionality with TTL-compatible voltage levels and propagation characteristics suitable for digital logic applications requiring XOR gate functionality.

Substitute Part Grouping Explanation

Substitution of the 74F86SJX is determined by strict equivalence across the following parameters:

• Logic Function: All substitutes must provide 4-channel, 2-input XOR gate functionality
• Electrical Specifications: Supply voltage (4.5V ~ 5.5V), output current (1mA/20mA), input logic levels (0.8V low, 2V high), and propagation delay (7ns @ 5V, 50pF) must be identical
• Operating Temperature Range: 0°C ~ 70°C
• Series Classification: 74F logic family
• Mounting Type: Surface mount configuration

The substitute parts identified—SN74F86NSR, SN74F86D, and SN74F86DR—all meet these electrical and functional requirements. Differences exist only in packaging format (14-SOIC vs. 14-SO) and product status, which do not affect electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

SN74F86DR (Texas Instruments) is the primary substitute for the 74F86SJX. This part carries Active product status, ensuring long-term availability and supply chain stability. It is ROHS3 compliant and available in Tape & Reel packaging, which is standard for high-volume production environments. Current inventory of 3800 units supports immediate procurement.

SN74F86NSR (Texas Instruments) serves as a secondary equivalent option. This part also maintains Active status and ROHS3 compliance. The primary distinction is the 14-SO package format (0.209" width) compared to the 14-SOIC format of SN74F86DR (0.154" width). This packaging difference may require PCB layout verification to confirm footprint compatibility. Inventory of 3980 units is available.

SN74F86D (Texas Instruments) is available as a tertiary option with Last Time Buy status, indicating limited future availability. While electrically equivalent, this part should be selected only when SN74F86DR or SN74F86NSR are unavailable. Inventory of 1609 units is currently in stock.

All three substitutes are electrically and functionally identical to the 74F86SJX and require no circuit modifications for direct replacement.

Frequently Asked Questions (FAQ)

Q: Can SN74F86DR be used as a direct replacement for 74F86SJX? A: Yes. The SN74F86DR is electrically and functionally equivalent. All electrical parameters, logic specifications, and operating characteristics are identical. The only differences are manufacturer (Texas Instruments vs. onsemi) and packaging format, neither of which affects circuit performance.

Q: What is the difference between SN74F86DR and SN74F86NSR? A: Both parts are electrically identical and carry Active product status. The primary difference is the package case: SN74F86DR uses 14-SOIC (0.154" width) while SN74F86NSR uses 14-SOIC (0.209" width). PCB footprint compatibility must be confirmed before selection, as the physical dimensions differ.

Q: Why is the 74F86SJX listed as obsolete? A: The 74F86SJX is an onsemi product that has reached end-of-life status. Texas Instruments continues to manufacture equivalent 74F86 variants in Active status, making substitution straightforward for design continuity.

Q: Are there any compliance differences between the main part and substitutes? A: The 74F86SJX carries REACH Unaffected status. All Texas Instruments substitutes (SN74F86D, SN74F86DR, SN74F86NSR) are ROHS3 compliant, which represents a higher environmental compliance standard and is preferred for new designs.

Q: Can I use SN74F86D if SN74F86DR is unavailable? A: Yes, SN74F86D is electrically equivalent. However, it carries Last Time Buy status, indicating limited future availability. For new production designs, SN74F86DR or SN74F86NSR are recommended to ensure long-term supply chain stability.

Q: Do I need to modify my circuit board to use these substitutes? A: No circuit modifications are required for electrical functionality. However, if switching between SN74F86DR (0.154" width) and SN74F86NSR (0.209" width), PCB footprint compatibility must be verified to ensure the component fits the existing land pattern.
