Engineering Selection Recommendations

SN74ACT10DR (Texas Instruments): This part is the direct equivalent to the SN74ACT10DRE4 from the same manufacturer. It maintains active product status and is available in higher inventory quantities (3230 pcs). The primary difference is packaging format (Tape & Reel vs. the original specification), which does not affect electrical or mechanical compatibility. This part is recommended for applications requiring Texas Instruments sourcing continuity.

MC74ACT10DR2G (onsemi): This part provides cross-manufacturer equivalence with identical electrical and mechanical specifications. It maintains active product status with 973 pcs in inventory. Selection of this part introduces a secondary manufacturer source, which may be beneficial for supply chain diversification and long-term availability assurance. RoHS3 compliance and REACH unaffected status are maintained.

Both substitute parts are suitable for direct replacement in applications currently using the SN74ACT10DRE4, with no circuit modifications required.

Frequently Asked Questions (FAQ)

Q: Can SN74ACT10DR be used as a direct replacement for SN74ACT10DRE4?

A: Yes. Both parts share identical electrical parameters (logic type, supply voltage, current ratings, input/output levels, propagation delay) and mechanical specifications (14-SOIC package, surface mount). The packaging format difference (Tape & Reel vs. tube) does not affect functional compatibility.

Q: What is the difference between SN74ACT10DR and MC74ACT10DR2G?

A: The primary difference is manufacturer: SN74ACT10DR is manufactured by Texas Instruments, while MC74ACT10DR2G is manufactured by onsemi. All electrical and mechanical parameters are identical. Selection depends on sourcing preferences and supply chain requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (SN74ACT10DR and MC74ACT10DR2G) are ROHS3 compliant with MSL rating of 1 (Unlimited) and REACH unaffected status, matching the original SN74ACT10DRE4 specifications.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All substitute parts use the identical 14-SOIC package with 0.154" width and 3.90mm dimensions. Pin configuration and footprint requirements are identical, allowing direct PCB substitution without layout modifications.

Q: Why is the original SN74ACT10DRE4 discontinued?

A: Product discontinuation at DiGi Electronics does not indicate functional obsolescence. The base product number 74ACT10 remains in production through active equivalent parts. Substitute parts SN74ACT10DR and MC74ACT10DR2G provide continued access to this logic function.
