Substitute Part Grouping Explanation

Substitution of the 74ACT10MTC 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 separately, as mechanical differences may require PCB layout adjustments.

Substitute parts are categorized as follows:

Direct Equivalents (Identical Electrical & Package Specifications): Parts matching all electrical parameters and using the 14-TSSOP package.

Similar Equivalents (Identical Electrical, Different Package): Parts matching all electrical parameters but using alternative surface mount packages (14-SSOP).

Parametric Equivalents (Identical Electrical, Different Status): Parts matching all electrical parameters but with discontinued or limited availability status.

Automotive Grade Variants: Parts meeting automotive qualification standards with extended temperature ranges.

Engineering Selection Recommendations

Primary Recommendation: MC74ACT10DTR2G (onsemi) is the direct replacement for 74ACT10MTC. Both parts are manufactured by onsemi, share identical electrical specifications, use the same 14-TSSOP package, and MC74ACT10DTR2G maintains active product status with ROHS3 compliance.

Alternative from Texas Instruments: SN74ACT10PWR provides direct electrical and package equivalence with active status and ROHS3 compliance. This option is suitable when onsemi supply is constrained.

Package Variant: SN74ACT10DBR offers identical electrical performance but uses the 14-SSOP package (0.209", 5.30mm width versus 0.173", 4.40mm width). This substitution requires PCB layout modification and is suitable only when package footprint constraints permit.

Automotive Grade Option: SN74ACT10QPWRG4Q1 extends the operating temperature range to -40°C ~ 125°C and includes AEC-Q100 automotive qualification. This part is appropriate for applications requiring automotive-grade components or extended temperature operation.

Avoid: SN74ACT10PW is discontinued at DiGi Electronics and should not be selected for new designs despite parametric equivalence.

Frequently Asked Questions (FAQ)

Q: Can MC74ACT10DTR2G directly replace 74ACT10MTC without PCB modifications?

A: Yes. MC74ACT10DTR2G is a direct replacement. Both parts use the 14-TSSOP package with identical pinout, electrical specifications, and supply voltage requirements. No PCB layout changes are required.

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

A: The 14-TSSOP package measures 0.173" (4.40mm) in width, while the 14-SSOP package measures 0.209" (5.30mm) in width. Both are surface mount packages with 14 pins, but the different widths require different PCB footprints. SN74ACT10DBR uses the wider 14-SSOP package and cannot be used as a direct drop-in replacement without PCB redesign.

Q: Why does SN74ACT10QPWRG4Q1 have a higher operating temperature range?

A: SN74ACT10QPWRG4Q1 is qualified to automotive standards (AEC-Q100) and is rated for -40°C ~ 125°C operation, compared to the standard -40°C ~ 85°C range. This extended range is a characteristic of automotive-grade components and does not affect compatibility with standard applications operating within the -40°C ~ 85°C window.

Q: Are all substitute parts ROHS3 compliant?

A: MC74ACT10DTR2G, SN74ACT10PWR, SN74ACT10DBR, SN74ACT10QPWRG4Q1, and SN74ACT10PW are all ROHS3 compliant. The original 74ACT10MTC does not list ROHS status in the provided data.

Q: Which substitute part has the best current availability?

A: SN74ACT10QPWRG4Q1 shows the highest inventory at 3600 pieces. MC74ACT10DTR2G (2632 pieces) and SN74ACT10DBR (2915 pieces) also maintain substantial stock levels. Availability should be confirmed with your component supplier.

Q: Can I use SN74ACT10PW for new production?

A: SN74ACT10PW is discontinued at DiGi Electronics and should not be selected for new designs. Use MC74ACT10DTR2G or SN74ACT10PWR instead.
