Key Parameters

Substitute Part Grouping Explanation

Substitution of the MC74ACT04DG is determined by strict equivalence across the following parameters:

• Logic Type: Inverter (6 channels, 1 input per channel)
• Electrical Specifications: Supply voltage 4.5V ~ 5.5V, output current 24mA, propagation delay 8.5ns @ 5V/50pF
• Package Type: 14-SOIC surface mount configuration
• Pin Compatibility: Identical pinout within the 74ACT04 base product family

Substitute parts are grouped into two categories:

Direct Manufacturer Equivalents maintain identical specifications and packaging across all electrical and mechanical parameters.

Parametric Equivalents maintain core electrical functionality and package form factor but may differ in secondary specifications such as quiescent current, operating temperature range, or packaging format (tube vs. cut tape).

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 74ACT04SCX (onsemi)

The 74ACT04SCX is the direct equivalent to the MC74ACT04DG with identical electrical specifications and package dimensions. As an active product from the original manufacturer, it provides the highest compatibility assurance. ROHS3 compliance and MSL 1 rating match the original part specifications.

Secondary Recommendation: SN74ACT04DR (Texas Instruments)

The SN74ACT04DR maintains electrical equivalence with identical propagation delay and package form factor. The lower quiescent current specification (2 µA vs. 4 µA) represents an improvement in power efficiency. Active product status and ROHS3 compliance ensure long-term availability. Cut tape and Digi-Reel packaging supports automated assembly processes.

Alternative Recommendation: SN74ACT04IDREP (Texas Instruments)

The SN74ACT04IDREP provides identical electrical performance to the SN74ACT04DR with tape and reel packaging suitable for high-volume production. Active product status and ROHS3 compliance are maintained.

Consideration: CD74ACT04M96 (Harris Corporation)

The CD74ACT04M96 maintains core electrical equivalence but carries obsolete product status and RoHS non-compliance. The extended operating temperature range (-55°C ~ 125°C) and slightly higher propagation delay (9.3ns) may be acceptable for specific applications but should not be selected for new designs requiring RoHS compliance.

Package Variant: SN74ACT04NSR (Texas Instruments)

The SN74ACT04NSR differs in package width (0.209" vs. 0.154"), which may affect PCB layout compatibility. Verify physical fit before selection.

Frequently Asked Questions (FAQ)

Q: Can I directly replace MC74ACT04DG with 74ACT04SCX?

A: Yes. The 74ACT04SCX is a direct equivalent with identical electrical specifications, package dimensions, and pin configuration. The only difference is packaging format (cut tape/Digi-Reel vs. original format) and active product status.

Q: What is the difference between the onsemi and Texas Instruments versions?

A: Both manufacturers produce 74ACT04 inverter ICs that meet the same electrical specifications. Texas Instruments versions (SN74ACT04DR, SN74ACT04IDREP, SN74ACT04D) feature lower quiescent current (2 µA vs. 4 µA). All versions maintain identical propagation delay, supply voltage range, and output current ratings. Selection depends on packaging format availability and supply chain preferences.

Q: Is the CD74ACT04M96 suitable for new designs?

A: The CD74ACT04M96 is obsolete and RoHS non-compliant. It should not be selected for new designs. Use active, ROHS3-compliant alternatives such as 74ACT04SCX or SN74ACT04DR.

Q: What does the packaging format difference mean?

A: Packaging format refers to how parts are supplied: Cut Tape (CT) & Digi-Reel® for automated pick-and-place assembly, Tape & Reel (TR) for high-volume production, and Tube for manual handling or lower-volume applications. Electrical performance is identical across all formats.

Q: Can I use SN74ACT04NSR if my PCB is designed for the standard 14-SOIC package?

A: The SN74ACT04NSR uses a wider 14-SOIC package (0.209" vs. 0.154" width). Physical fit must be verified against your PCB footprint before use. If your design specifies the narrower package, use 74ACT04SCX, SN74ACT04DR, SN74ACT04IDREP, or SN74ACT04D instead.

Q: Are all substitute parts ROHS3 compliant?

A: No. The CD74ACT04M96 is RoHS non-compliant. All other listed substitutes (74ACT04SCX, 74ACT04SC, SN74ACT04DR, SN74ACT04IDREP, SN74ACT04NSR, SN74ACT04D) are ROHS3 compliant.

Q: What is the MSL rating and why does it matter?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture control requirements. All listed substitutes maintain MSL 1 rating, ensuring consistent handling and storage procedures.
