Substitute Part Grouping Explanation

Substitution of the 74ACT10MTCX 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), propagation delay (9ns @ 5V, 50pF), and operating temperature range (-40°C ~ 85°C). Package compatibility is evaluated based on the 14-pin surface mount footprint, with both 14-TSSOP and 14-SSOP packages considered mechanically compatible for standard PCB layouts.

Substitute parts are categorized as follows:

Direct Manufacturer Equivalents: Parts with identical electrical specifications and 14-TSSOP packaging from alternative manufacturers.

Similar Equivalents: Parts meeting all electrical specifications with minor package variations (14-SSOP vs. 14-TSSOP).

Parametric Equivalents: Parts with identical electrical performance and packaging.

Automotive Grade Variants: Parts meeting all specifications with extended temperature range and automotive qualification.

Engineering Selection Recommendations

Primary Recommendation: MC74ACT10DTR2G (onsemi) is the direct equivalent from the original manufacturer with active product status and ROHS3 compliance. This part maintains identical electrical specifications and 14-TSSOP packaging, ensuring drop-in compatibility.

Secondary Recommendation: SN74ACT10PWR (Texas Instruments) provides parametric equivalence with active product status, ROHS3 compliance, and identical 14-TSSOP packaging. This part is suitable for applications requiring cross-manufacturer sourcing.

Extended Temperature Applications: SN74ACT10QPWRG4Q1 (Texas Instruments) extends the operating temperature range to -40°C ~ 125°C and includes AEC-Q100 automotive qualification. This variant is appropriate for automotive and high-temperature industrial applications.

Package Variant: SN74ACT10DBR (Texas Instruments) is an active alternative with 14-SSOP packaging. While electrically equivalent, the package footprint differs slightly (0.209" vs. 0.173" width). PCB layout verification is required before substitution.

Frequently Asked Questions (FAQ)

Q: Can I substitute the obsolete 74ACT10MTCX with MC74ACT10DTR2G?

A: Yes. MC74ACT10DTR2G is a direct equivalent from onsemi with identical electrical specifications, supply voltage range, output current capability, propagation delay, and 14-TSSOP packaging. The part is currently active and ROHS3 compliant.

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

A: Both are 14-pin surface mount packages with different body widths. 14-TSSOP measures 0.173" (4.40mm) width, while 14-SSOP measures 0.209" (5.30mm) width. Pin pitch and footprint compatibility must be verified against your PCB design before substitution.

Q: Is SN74ACT10QPWRG4Q1 suitable for my standard industrial application?

A: SN74ACT10QPWRG4Q1 is qualified for automotive applications with an extended operating temperature range of -40°C ~ 125°C. For standard industrial applications operating within -40°C ~ 85°C, SN74ACT10PWR or MC74ACT10DTR2G are appropriate selections.

Q: Are all substitute parts ROHS3 compliant?

A: MC74ACT10DTR2G, SN74ACT10PW, SN74ACT10DBR, SN74ACT10QPWRG4Q1, and SN74ACT10PWR are all ROHS3 compliant. The original 74ACT10MTCX is listed as REACH Unaffected.

Q: What packaging options are available for the 74ACT10 logic gate?

A: Active substitutes are available in 14-TSSOP (Cut Tape, Tube, and Tape & Reel packaging options) and 14-SSOP (Tape & Reel) configurations. Packaging selection depends on procurement volume and assembly requirements.
