Engineering Selection Recommendations

SN74ACT00DR (Texas Instruments) is the primary direct substitute. It maintains identical electrical specifications and quiescent current characteristics as the original SN74ACT00D while offering active product status and significantly higher inventory availability. The packaging format differs (Cut Tape & Digi-Reel versus Tube), but the component itself is electrically equivalent.

74ACT00SCX (Fairchild Semiconductor) provides an alternative from a different manufacturer with matching electrical performance and quiescent current. Product status is active with substantial inventory. Packaging details are not specified in available data.

MC74ACT00DG and MC74ACT00DR2G (onsemi) are manufacturer-recommended alternatives with extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C) and slightly elevated quiescent current (4 µA versus 2 µA). These parts are suitable for applications requiring wider temperature operation. MC74ACT00DG is supplied in Tube packaging; MC74ACT00DR2G is supplied in Tape & Reel format.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical 14-SOIC package dimensions, ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can SN74ACT00DR be used as a direct replacement for SN74ACT00D?

A: Yes. SN74ACT00DR is electrically and functionally equivalent to SN74ACT00D. Both maintain 2 µA quiescent current, identical propagation delay, and matching input/output specifications. The primary difference is packaging format (Cut Tape & Digi-Reel versus Tube) and product status (Active versus Discontinued).

Q: What is the difference between the Texas Instruments and onsemi substitutes?

A: Texas Instruments substitutes (SN74ACT00DR, 74ACT00SCX) maintain the original -40°C ~ 85°C operating temperature range and 2 µA quiescent current. onsemi parts (MC74ACT00DG, MC74ACT00DR2G) extend the operating temperature to -55°C ~ 125°C and increase quiescent current to 4 µA. Select onsemi parts only if extended temperature operation is required.

Q: Are all substitute parts in the same 14-SOIC package?

A: Yes. All listed substitutes use the 14-SOIC (0.154", 3.90mm Width) surface mount package, ensuring identical PCB footprint and mounting compatibility.

Q: What packaging options are available for substitutes?

A: SN74ACT00DR is available in Cut Tape & Digi-Reel format. MC74ACT00DG is supplied in Tube packaging. MC74ACT00DR2G is supplied in Tape & Reel format. Packaging selection depends on production volume and assembly process requirements.

Q: Do all substitutes meet RoHS and MSL requirements?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original SN74ACT00D specifications.
