Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC4075MT is determined by the following critical parameters:

• Logic Function: All substitute parts must implement 3-channel, 3-input OR gate logic
• Electrical Specifications: Supply voltage range (2V–6V), propagation delay (17ns @ 6V, 50pF), and output current ratings must match
• Package Compatibility: 14-SOIC package footprint is required for direct PCB replacement
• Thermal Range: Operating temperature range must support the application requirements
• Compliance: RoHS3 compliance and MSL rating (1 – Unlimited) must be maintained

Substitute parts are grouped by packaging format (Cut Tape, Tape & Reel, Bulk) and manufacturer, all meeting the core electrical and functional requirements of the 74HC4075 base product number.

Parameter Comparison

Engineering Selection Recommendations

CD74HC4075M96 (Texas Instruments) is the primary parametric equivalent. It maintains identical electrical specifications and thermal range as the original CD74HC4075MT while offering active product status. The difference in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) does not affect functional compatibility on the PCB.

74HC4075D,653 (Nexperia USA Inc.) is a manufacturer-recommended substitute with full electrical equivalence and active status. The operating temperature range is -40°C to 125°C, which is narrower than the original part's -55°C to 125°C. This substitute is suitable for applications not requiring operation below -40°C.

74HC4075D,652 (NXP Semiconductors) is a manufacturer-recommended substitute available in bulk packaging. Complete electrical parameter specifications are not provided in the datasheet reference; verification of full compatibility with application requirements is necessary before selection.

All three substitute parts maintain ROHS3 compliance and MSL rating (1 – Unlimited), ensuring regulatory and environmental compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can CD74HC4075M96 replace CD74HC4075MT directly on the PCB?

A: Yes. Both parts use the 14-SOIC package with identical pinout and electrical specifications. The packaging format difference (Cut Tape & Digi-Reel® versus Tape & Reel) affects procurement and handling only, not PCB assembly or functionality.

Q: What is the key difference between 74HC4075D,653 and the original CD74HC4075MT?

A: The operating temperature range differs. The 74HC4075D,653 operates from -40°C to 125°C, while the CD74HC4075MT operates from -55°C to 125°C. For applications requiring operation below -40°C, the CD74HC4075M96 is recommended.

Q: Are all substitute parts RoHS3 compliant?

A: CD74HC4075M96 and 74HC4075D,653 are confirmed ROHS3 compliant. RoHS status for 74HC4075D,652 is not specified in the provided data; verification with the supplier is recommended.

Q: What does MSL rating 1 (Unlimited) mean?

A: MSL 1 indicates the part has unlimited shelf life and requires no special moisture control during storage or handling, simplifying inventory management and logistics.

Q: Can I use 74HC4075D,652 in bulk packaging for production?

A: Yes, bulk packaging is suitable for high-volume production. However, complete electrical parameter specifications should be verified with NXP Semiconductors before design release.

Q: Do all substitute parts have the same propagation delay?

A: CD74HC4075M96 and 74HC4075D,653 both specify 17ns propagation delay @ 6V, 50pF. The 74HC4075D,652 datasheet does not provide this specification; confirmation is required if timing-critical applications are involved.
