74ACT10SCX NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74ACT10SCX is a NAND Gate IC featuring 3 channels with 3 inputs per channel in a 14-SOIC surface mount package, manufactured by onsemi. This logic component operates within the 4.5V to 5.5V supply voltage range and is designed for standard TTL-compatible digital applications. The part is currently listed as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74ACT10SCX is determined by strict equivalence across the following critical parameters: logic type (NAND Gate), circuit count (3 channels), input count (3 inputs per channel), supply voltage range (4.5V ~ 5.5V), output current capability (24mA high and low), input logic thresholds (0.8V low, 2V high), propagation delay (9ns @ 5V, 50pF), operating temperature range (-40°C ~ 85°C), and package type (14-SOIC surface mount).

Substitute parts are categorized as follows:

Direct Manufacturer Equivalents: Parts meeting all electrical and mechanical specifications with identical propagation delay and operating temperature range.

Similar Manufacturer Parts: Parts meeting all electrical and mechanical specifications but with extended operating temperature range (-55°C ~ 125°C) and increased propagation delay (14.6ns @ 5V, 50pF), which remain functionally compatible within the original design envelope.

Parametric Equivalents: Parts meeting all electrical specifications with identical propagation delay and operating temperature range, differing only in packaging format.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: MC74ACT10DR2G (onsemi) is the direct equivalent with active product status, identical electrical specifications, and ROHS3 compliance. This part maintains the same manufacturer lineage as the original 74ACT10SCX.

Secondary Recommendation: SN74ACT10DR (Texas Instruments) provides identical electrical performance with active product status and ROHS3 compliance. This part is available in Tape & Reel packaging suitable for automated assembly.

Alternative Selection: CD74ACT10M96 (Texas Instruments) is an active product with ROHS3 compliance and extended operating temperature range (-55°C ~ 125°C). The increased propagation delay (14.6ns vs. 9ns) remains within acceptable margins for most standard logic applications but should be evaluated against timing-critical circuit requirements.

Not Recommended for New Designs: SN74ACT10D (Last Time Buy status) and CD74ACT10M (Obsolete status) should not be selected for new production designs due to product lifecycle constraints.

Frequently Asked Questions (FAQ)

Q: Can I use CD74ACT10M96 as a direct replacement for 74ACT10SCX?

A: Yes. CD74ACT10M96 meets all electrical specifications and package requirements. The extended operating temperature range (-55°C ~ 125°C) and increased propagation delay (14.6ns vs. 9ns) are compatible with standard 74ACT10 applications. Verify timing margins in designs with propagation delay-sensitive circuits.

Q: What is the difference between MC74ACT10DR2G and SN74ACT10DR?

A: Both parts are parametric equivalents with identical electrical specifications, operating temperature range, and propagation delay. The primary differences are manufacturer (onsemi vs. Texas Instruments) and packaging format (Tape & Reel for both). Selection depends on supply chain availability and procurement preferences.

Q: Why does CD74ACT10M have different propagation delay specifications?

A: CD74ACT10M specifies 14.6ns propagation delay compared to 9ns for other variants. This difference reflects manufacturing process variations between Harris Corporation and other manufacturers. The part remains functionally compatible within the 74ACT10 logic family for standard applications.

Q: Is RoHS compliance required for my application?

A: RoHS compliance status is provided for regulatory and environmental considerations. MC74ACT10DR2G, SN74ACT10D, CD74ACT10M96, and SN74ACT10DR are ROHS3 compliant. CD74ACT10M is RoHS non-compliant. Verify compliance requirements with your procurement and regulatory departments.

Q: What packaging formats are available?

A: All substitute parts are available in 14-SOIC surface mount package. Packaging options include Tube (SN74ACT10D, CD74ACT10M) and Tape & Reel (MC74ACT10DR2G, CD74ACT10M96, SN74ACT10DR). Select based on assembly process requirements and order quantities.

Q: Can I mix different manufacturers in the same design?

A: Yes. All listed parts meet identical electrical specifications and package requirements. Cross-manufacturer substitution is standard practice in logic IC applications. Ensure consistent sourcing within production batches to maintain supply chain continuity.
