SN74ACT86D Equivalent & Substitute Parts

Part Overview

The SN74ACT86D is a 4-channel XOR (Exclusive OR) logic gate IC manufactured by Texas Instruments in a 14-SOIC surface mount package. This component is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design requirements and production needs. The part operates within a 4.5V to 5.5V supply voltage range and is suitable for digital logic applications requiring exclusive OR functionality.

Parameter Comparison

Engineering Selection Recommendations

SN74ACT86DR (Texas Instruments): This part is the preferred direct substitute. It is manufactured by Texas Instruments, the original manufacturer of the SN74ACT86D, and maintains active product status. All electrical and mechanical parameters are identical. The packaging format differs (Cut Tape and Digi-Reel® versus Tube), which may affect procurement and handling but does not impact functional compatibility. ROHS3 compliance and unlimited MSL rating are maintained.

MC74ACT86DG (onsemi): This part is a parametric equivalent manufactured by onsemi. All electrical specifications and package dimensions match the SN74ACT86D exactly. However, the product status is listed as Obsolete, which may affect long-term availability and supply chain reliability. This part is suitable for applications where onsemi sourcing is preferred or where Texas Instruments parts are unavailable, but availability should be confirmed before design commitment.

Frequently Asked Questions (FAQ)

Q: Can SN74ACT86DR be used as a direct replacement for SN74ACT86D?

A: Yes. The SN74ACT86DR is a direct substitute. All electrical parameters, logic functionality, operating temperature range, and 14-SOIC package dimensions are identical. The only difference is packaging format (Cut Tape/Digi-Reel® versus Tube) and active product status.

Q: What is the difference between the packaging formats (Tube vs. Cut Tape)?

A: Tube packaging is used for manual handling and smaller quantity orders. Cut Tape and Digi-Reel® packaging is used for automated assembly and higher volume production. The actual component and its electrical performance are identical; the difference is in how the parts are supplied and handled during manufacturing.

Q: Is MC74ACT86DG suitable for new designs?

A: MC74ACT86DG meets all electrical and mechanical specifications of the SN74ACT86D. However, its Obsolete product status indicates limited availability. For new designs, SN74ACT86DR is recommended due to its Active status and assured supply chain continuity.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 14-SOIC package with identical pin assignments and functionality. They are mechanically and electrically interchangeable at the board level.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Yes. Both SN74ACT86DR and MC74ACT86DG are ROHS3 compliant with unlimited Moisture Sensitivity Level (MSL 1), matching the compliance profile of the original SN74ACT86D.
