MC74ACT10N NAND Gate IC Equivalent & Substitute Parts

Part Overview

The MC74ACT10N is a triple 3-input NAND gate logic IC manufactured by onsemi in a 14-PDIP package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The part operates within the 74ACT logic family standard, which defines compatible electrical and mechanical parameters across multiple manufacturers.

Substitute Part Grouping Explanation

Substitution for the MC74ACT10N is determined by strict adherence to the 74ACT logic family standard. All substitute parts must maintain identical functional specifications: triple 3-input NAND gate configuration, 14-PDIP package, through-hole mounting, and electrical parameters within the defined ranges. The key parameters that govern substitution are:

• Logic family and base product number (74ACT10)
• Number of circuits (3) and inputs per circuit (3)
• Supply voltage range (4.5V ~ 5.5V)
• Output current capability (24mA high and low)
• Input logic thresholds (0.8V low, 2V high)
• Package type and physical dimensions (14-DIP)
• Mounting configuration (Through Hole)

Substitute parts are classified as either direct equivalents (matching all primary electrical and mechanical parameters) or similar alternatives (meeting functional requirements with acceptable parameter variations within engineering tolerances).

Engineering Selection Recommendations

SN74ACT10N (Texas Instruments) is the primary direct equivalent for MC74ACT10N replacement. This part maintains active product status, ensuring long-term availability and supply chain stability. It meets all electrical and mechanical specifications identically to the original part and carries ROHS3 compliance certification, supporting modern manufacturing and environmental standards.

CD74ACT10E (Harris Corporation) functions as a compatible alternative with extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C) and slightly increased propagation delay (14.6ns versus 9ns). This part is suitable for applications requiring broader temperature operation, though its obsolete status may limit future availability. The extended temperature range and acceptable delay variance make it viable for specific design requirements where thermal performance is prioritized.

Selection between these substitutes depends on product lifecycle requirements, compliance mandates, and thermal operating conditions of the target application.

Frequently Asked Questions (FAQ)

Q: Can SN74ACT10N directly replace MC74ACT10N without circuit modification?

A: Yes. SN74ACT10N is a direct equivalent meeting all electrical parameters, logic configuration, and package specifications. No circuit modifications are required for pin-compatible substitution in 14-DIP through-hole applications.

Q: What is the primary difference between SN74ACT10N and CD74ACT10E?

A: SN74ACT10N maintains identical propagation delay (9ns) and operating temperature range (-40°C ~ 85°C) as the original MC74ACT10N. CD74ACT10E offers extended temperature operation (-55°C ~ 125°C) but exhibits increased propagation delay (14.6ns). Both are functionally compatible within the 74ACT logic family.

Q: Does RoHS compliance affect substitution decisions?

A: RoHS compliance is a regulatory and supply chain consideration. SN74ACT10N carries ROHS3 certification, supporting compliance with modern environmental standards. MC74ACT10N and CD74ACT10E are RoHS non-compliant. Selection depends on manufacturing location, customer requirements, and regulatory jurisdiction.

Q: Are all three parts physically interchangeable?

A: Yes. All three parts use identical 14-DIP (0.300", 7.62mm) packaging with through-hole mounting. Physical board layout and footprint design require no modification for substitution.

Q: Which substitute should be selected for new designs?

A: SN74ACT10N is recommended for new designs due to active product status, ROHS3 compliance, and guaranteed long-term availability from Texas Instruments.
