Substitute Part Grouping Explanation

Substitution of the SN74ACT00PW is determined by the following criteria:

Functional Equivalence: All substitute parts must maintain identical logic type (NAND Gate), circuit count (4 channels), and input configuration (2-input).

Electrical Compatibility: Supply voltage range (4.5V ~ 5.5V), output current capability (24mA high and low), propagation delay (9ns @ 5V, 50pF), and input logic levels (0.8V low, 2V high) must be matched or exceeded.

Package Compatibility: All parts use the 14-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm width).

Compliance Requirements: All substitute parts maintain ROHS3 compliance and REACH unaffected status.

The substitute parts are grouped into two categories: direct packaging equivalents and manufacturer-recommended alternatives with extended operating temperature ranges.

Engineering Selection Recommendations

SN74ACT00PWR (Texas Instruments): Direct substitute with identical electrical specifications and operating temperature range. Active product status ensures ongoing availability. Tape & Reel packaging is standard for production volume applications.

74ACT00MTCX (Fairchild Semiconductor): Functionally equivalent with matching electrical parameters and operating temperature range. Active product status supports continued sourcing. Suitable for applications requiring alternative manufacturer sourcing.

MC74ACT00DTR2G (onsemi): Manufacturer-recommended alternative with extended operating temperature range (-55°C ~ 125°C) compared to the original specification (-40°C ~ 85°C). Quiescent current is 4 µA versus 2 µA in the main part. Active product status and Tape & Reel packaging support production requirements. Select this part for applications requiring wider temperature operation or when onsemi supply chain preference is established.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with the original SN74ACT00PW.

Frequently Asked Questions (FAQ)

Q: Can SN74ACT00PWR be used as a direct replacement for SN74ACT00PW?

A: Yes. SN74ACT00PWR is a direct electrical and functional equivalent with identical supply voltage, output current, propagation delay, and operating temperature specifications. The difference is packaging format: SN74ACT00PW uses Tube packaging while SN74ACT00PWR uses Tape & Reel (TR) packaging.

Q: What is the difference between the main part and MC74ACT00DTR2G?

A: MC74ACT00DTR2G has an extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C) and higher quiescent current (4 µA versus 2 µA). All other electrical parameters including supply voltage, output current, propagation delay, and input logic levels are identical. Select MC74ACT00DTR2G for applications requiring operation at temperatures below -40°C or above 85°C.

Q: Are all substitute parts in the same package?

A: Yes. All substitute parts use the 14-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm width). PCB layout and footprint compatibility is maintained across all parts.

Q: Which substitute part should I select for new production?

A: SN74ACT00PWR is the recommended choice for new production due to active product status from Texas Instruments and standard Tape & Reel packaging. If extended temperature operation is required, select MC74ACT00DTR2G.

Q: Do all substitute parts meet RoHS and REACH requirements?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, maintaining regulatory compatibility with the original SN74ACT00PW.
