74ACTQ10MTCX NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74ACTQ10MTCX is a 3-channel, 3-input NAND gate logic IC manufactured by onsemi in a 14-TSSOP surface mount package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support. The 74ACT10 logic family provides functionally identical alternatives from active product lines, ensuring design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitution of the 74ACTQ10MTCX is determined by the following criteria:

Functional Equivalence: All substitute parts maintain identical logic function (3-channel, 3-input NAND gate), circuit count, input configuration, and voltage supply range (4.5V ~ 5.5V).

Electrical Compatibility: Substitute parts share the same input logic levels (0.8V low, 2V high) and output current specifications (24mA high/low), ensuring direct pin-for-pin compatibility in existing circuit designs.

Package Compatibility: The primary substitutes use 14-TSSOP or 14-SSOP packages, both surface mount configurations with identical pinout and footprint compatibility for standard PCB layouts.

Operating Temperature: All substitutes operate within the -40°C ~ 85°C range, with one option (SN74ACT10QPWRG4Q1) extending to -40°C ~ 125°C for automotive applications.

Product Status: Substitutes are selected from active product lines to ensure long-term availability and supply chain continuity.

Engineering Selection Recommendations

Primary Recommendation: MC74ACT10DTR2G (onsemi) or SN74ACT10PWR (Texas Instruments) are the preferred substitutes for standard applications. Both are active products with ROHS3 compliance and identical package footprints to the original 74ACTQ10MTCX.

For Automotive Applications: SN74ACT10QPWRG4Q1 is qualified to AEC-Q100 standards with extended operating temperature range (-40°C ~ 125°C), suitable for automotive-grade designs requiring higher temperature performance.

For Tape & Reel Packaging: SN74ACT10PWR and SN74ACT10QPWRG4Q1 are supplied in standard Tape & Reel format, optimized for automated assembly processes.

Package Consideration: SN74ACT10DBR uses 14-SSOP package (5.30mm width) versus 14-TSSOP (4.40mm width). Verify PCB footprint compatibility before selection, as package dimensions differ slightly.

Availability: All recommended substitutes maintain active product status with established supply chains, ensuring long-term component availability.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 74ACTQ10MTCX with any of these substitutes?

A: Yes, all listed substitutes are pin-for-pin compatible with identical logic function, voltage supply range, input/output specifications, and operating temperature range. Verify package footprint compatibility for your PCB layout.

Q: What is the difference between 14-TSSOP and 14-SSOP packages?

A: Both are surface mount packages with identical pinout. The primary difference is package width: 14-TSSOP measures 4.40mm width, while 14-SSOP measures 5.30mm width. Confirm your PCB footprint specification before selecting SN74ACT10DBR.

Q: Why does the 74ACTQ10MTCX show lower quiescent current (2 µA) than substitutes (4 µA)?

A: The quiescent current difference reflects manufacturing process variations between onsemi and Texas Instruments. Both values remain within acceptable logic IC specifications and do not affect functional compatibility or circuit operation.

Q: Which substitute should I use for automotive applications?

A: SN74ACT10QPWRG4Q1 is the automotive-qualified option, certified to AEC-Q100 standards with extended operating temperature range (-40°C ~ 125°C). Use this part for automotive-grade designs.

Q: Are all substitutes RoHS compliant?

A: All active substitute parts (MC74ACT10DTR2G, SN74ACT10DBR, SN74ACT10PW, SN74ACT10PWR, SN74ACT10QPWRG4Q1) are ROHS3 compliant. The original 74ACTQ10MTCX does not specify RoHS status.

Q: What packaging format should I select for high-volume production?

A: For automated assembly, select Tape & Reel (TR) packaging: SN74ACT10PWR or SN74ACT10QPWRG4Q1. For manual assembly or lower volumes, Tube packaging (SN74ACT10PW) or Cut Tape (MC74ACT10DTR2G) are suitable alternatives.
