SN74ACT10D Equivalent & Substitute Parts

Part Overview

The SN74ACT10D is a NAND Gate IC featuring 3 channels with 3 inputs per channel in a 14-SOIC surface mount package, manufactured by Texas Instruments. This component is classified as Last Time Buy, indicating limited availability of the tube packaging variant. The SN74ACT10D operates within the 74ACT logic family and is fully RoHS3 compliant with MSL Level 1 rating. Substitute parts are necessary due to product status transitions and packaging availability constraints while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74ACT10D is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part SN74ACT10DR maintains identical specifications for logic configuration, voltage supply range, quiescent current, output current ratings, input logic levels, propagation delay, operating temperature range, and package dimensions. The primary difference is packaging format: the main part is supplied in Tube packaging with Last Time Buy status, while the substitute is supplied in Tape & Reel (TR) format with Active product status. Both parts share the same base product number (74ACT10), manufacturer (Texas Instruments), and comply with identical regulatory standards (RoHS3, REACH Unaffected, EAR99 ECCN classification).

Parameter Comparison

Engineering Selection Recommendations

The SN74ACT10DR is the direct functional equivalent of the SN74ACT10D. Selection between these parts should be based on packaging and supply chain requirements. The SN74ACT10D in Tube packaging is designated Last Time Buy, indicating that future availability is limited and existing inventory will not be replenished. The SN74ACT10DR in Tape & Reel format maintains Active product status with higher current inventory levels (3230 pcs vs. 2260 pcs), ensuring long-term supply continuity. Both parts satisfy identical electrical performance requirements, thermal specifications, and regulatory compliance standards. For new designs or long-term production requirements, the SN74ACT10DR is the appropriate selection due to its Active status and standard tape & reel packaging format used in automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Are SN74ACT10D and SN74ACT10DR electrically identical? A: Yes. Both parts are manufactured by Texas Instruments within the 74ACT logic family and share identical electrical specifications including supply voltage (4.5V ~ 5.5V), quiescent current (4 µA max), output current (24mA), input logic levels, propagation delay (9ns @ 5V, 50pF), and operating temperature range (-40°C ~ 85°C).

Q: What is the difference between these parts? A: The primary difference is packaging format and product status. The SN74ACT10D is supplied in Tube packaging with Last Time Buy status, while the SN74ACT10DR is supplied in Tape & Reel (TR) format with Active product status. Both use the same 14-SOIC package dimensions (0.154", 3.90mm Width).

Q: Can I use SN74ACT10DR as a direct replacement for SN74ACT10D? A: Yes. The SN74ACT10DR is a direct substitute with identical electrical and mechanical specifications. The only consideration is packaging format compatibility with your assembly process.

Q: Why is SN74ACT10D marked as Last Time Buy? A: Last Time Buy designation indicates that the manufacturer will not continue production of this part in its current packaging format. Existing inventory will be sold until depletion, after which the part will no longer be available.

Q: Are both parts RoHS compliant? A: Yes. Both SN74ACT10D and SN74ACT10DR are RoHS3 compliant with MSL Level 1 rating and REACH Unaffected status.

Q: Which part should I specify for new designs? A: For new designs, specify SN74ACT10DR due to its Active product status and standard Tape & Reel packaging format, which ensures long-term availability and compatibility with automated assembly processes.
