Substitute Part Grouping Explanation

Substitution for the CD74ACT86M96G4 is determined by strict equivalence across the following critical parameters:

Logic Type: XOR (Exclusive OR) with 4 channels and 2 inputs per channel
Voltage Supply Range: 4.5V ~ 5.5V
Output Drive Capability: 24mA high and low
Input Logic Levels: 0.8V low threshold, 2V high threshold
Package: 14-SOIC surface mount form factor
Base Product Number: 74ACT86 series

Substitute parts must maintain identical functional specifications and pinout compatibility. Propagation delay and operating temperature range variations are acceptable within the 74ACT86 product family, provided all other electrical parameters remain within specification.

Engineering Selection Recommendations

MC74ACT86DR2G (onsemi) is the primary substitute for new designs and production. This part is currently active in the market, ROHS3 compliant, and available in Tape & Reel packaging for automated assembly. The faster propagation delay (9.5ns vs. 14.6ns) provides improved performance margins. Operating temperature range is -40°C ~ 85°C, which is suitable for standard industrial and commercial applications.

MC74ACT86DG (onsemi) serves as an alternative substitute with identical electrical specifications to MC74ACT86DR2G but is marked as obsolete. This part is available in Tube packaging and may be considered only if MC74ACT86DR2G is unavailable.

CD74ACT86M96 (Harris Corporation) is a parametric equivalent but is RoHS non-compliant and marked obsolete. This part should not be selected for new designs requiring RoHS compliance.

For applications requiring the extended operating temperature range of -55°C ~ 125°C, no direct substitute maintains this specification within the 74ACT86 family. Design review is necessary to determine if the -40°C ~ 85°C range of onsemi parts is acceptable.

Frequently Asked Questions (FAQ)

Q: Can MC74ACT86DR2G replace CD74ACT86M96G4 directly?

A: Yes. Both parts share identical logic functionality, pinout, voltage supply range, input/output levels, and 14-SOIC package. The faster propagation delay of MC74ACT86DR2G (9.5ns vs. 14.6ns) is a performance improvement. Operating temperature range differs (-40°C ~ 85°C vs. -55°C ~ 125°C); verify this is acceptable for your application.

Q: What is the difference between MC74ACT86DG and MC74ACT86DR2G?

A: Both parts are manufactured by onsemi with identical electrical specifications and performance. The primary difference is packaging: MC74ACT86DG is supplied in Tube format, while MC74ACT86DR2G is supplied in Tape & Reel format. MC74ACT86DR2G is currently active; MC74ACT86DG is obsolete.

Q: Why is CD74ACT86M96 not recommended as a substitute?

A: CD74ACT86M96 is RoHS non-compliant and marked obsolete. While electrically equivalent, it does not meet current environmental and regulatory requirements for new production.

Q: Are there any pinout differences between these parts?

A: No. All substitute parts maintain the same 14-SOIC pinout and are functionally interchangeable at the circuit level.

Q: What should I do if my application requires the -55°C ~ 125°C operating temperature range?

A: The onsemi substitutes operate only to -40°C ~ 85°C. Evaluate whether this narrower range meets your system requirements. If extended temperature operation is mandatory, alternative logic gate families or custom sourcing may be necessary.
