Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74AC175ME4 is determined by strict equivalence across the following critical parameters:

• Base product number (74AC175 series)
• Functional classification (D-type flip-flop, 1 element, 4 bits)
• Output configuration (complementary)
• Electrical specifications (clock frequency, propagation delay, voltage supply, output current)
• Trigger mechanism (positive edge)
• Package type (16-SOIC with identical dimensions)
• Compliance certifications (RoHS3, REACH status)

The primary distinction between the main part and substitute parts is packaging format and product status. The CD74AC175ME4 uses tube packaging and is discontinued, while substitute parts may use alternative packaging formats such as tape and reel while maintaining identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The CD74AC175M96 is a direct functional equivalent to the CD74AC175ME4. Both parts share identical electrical specifications, thermal operating range, and physical package dimensions. The primary difference is product status and packaging format.

The CD74AC175M96 is currently active in production, making it the appropriate selection for new designs or inventory replenishment. The tape and reel packaging format is standard for high-volume manufacturing and automated assembly processes.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across global markets. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for storage or handling.

Frequently Asked Questions (FAQ)

Q: Can the CD74AC175M96 be used as a direct replacement for the CD74AC175ME4?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, operating parameters, and 16-SOIC package dimensions. The only difference is packaging format (tape and reel versus tube) and product status (active versus discontinued).

Q: Are there any differences in electrical performance between these parts?

A: No. Both parts have identical clock frequency (100 MHz), propagation delay (12.2ns at 5V, 50pF), voltage supply range (1.5V to 5.5V), output current (24mA), and quiescent current (8 µA) specifications.

Q: Does the packaging format affect circuit performance?

A: No. Packaging format (tape and reel versus tube) does not affect electrical performance or functionality. The difference is in handling, storage, and assembly process compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the CD74AC175ME4 and CD74AC175M96 are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements.

Q: What is the MSL rating for these parts?

A: Both parts have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints for storage or handling procedures.

Q: Can these parts be used in the same PCB assembly process?

A: Yes. Both parts use identical 16-SOIC surface mount packages with the same pin configuration and footprint. The CD74AC175M96 in tape and reel format is optimized for automated pick-and-place assembly.
