CD74HCT08MDRDL Equivalent & Substitute Parts

Part Overview

The CD74HCT08MDRDL is a 4-channel AND gate logic integrated circuit manufactured by Texas Instruments in the 74HCT series. This component functions as a digital logic gate with four independent 2-input AND circuits integrated into a single 14-pin SOIC package. The device operates within the standard TTL voltage range of 4.5V to 5.5V and is designed for surface mount applications.

The CD74HCT08MDRDL maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when inventory constraints necessitate sourcing from alternative distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HCT08MDRDL is determined by strict equivalence across the following critical parameters:

Functional Equivalence: Logic type (AND Gate), number of circuits (4), and number of inputs per circuit (2) must remain identical.

Electrical Equivalence: Supply voltage range (4.5V ~ 5.5V) and operating temperature range (-55°C ~ 125°C) must match exactly.

Package Equivalence: Physical package type must be 14-SOIC with identical dimensions (0.154", 3.90mm Width) to ensure mechanical compatibility with printed circuit board layouts and assembly equipment.

Compliance Equivalence: RoHS3 compliance and Moisture Sensitivity Level 1 status must be maintained.

Series Equivalence: Both parts belong to the 74HCT logic series, ensuring TTL-compatible input and output characteristics.

The CD74HCT08M96 qualifies as a substitute part because it maintains identical functional, electrical, package, and compliance specifications. The primary distinction is packaging format: the CD74HCT08MDRDL is supplied in Digi-Reel format, while the CD74HCT08M96 is available in Cut Tape (CT) and Digi-Reel packaging options.

Parameter Comparison

Engineering Selection Recommendations

Both the CD74HCT08MDRDL and CD74HCT08M96 are Active products manufactured by Texas Instruments with identical functional and electrical specifications. Selection between these parts should be based on the following criteria:

Packaging Format Requirements: The CD74HCT08MDRDL is specified for Digi-Reel packaging, while the CD74HCT08M96 offers both Cut Tape and Digi-Reel options. Choose based on your assembly process requirements and tape feeder compatibility.

Inventory Availability: The CD74HCT08M96 maintains significantly higher inventory levels (27,700 pieces) compared to the CD74HCT08MDRDL (1,015 pieces), making it preferable for high-volume production or when supply chain continuity is critical.

Compliance Certification: Both parts maintain ROHS3 compliance and are suitable for applications requiring environmental and regulatory adherence. The CD74HCT08M96 includes additional REACH Unaffected status and ECCN/HTSUS classifications for international trade documentation.

Functional Interchangeability: Direct substitution is permissible in all circuit applications where the CD74HCT08MDRDL was originally specified, provided the physical package footprint and tape format are compatible with manufacturing equipment.

Frequently Asked Questions (FAQ)

Q: Can the CD74HCT08M96 be used as a direct replacement for the CD74HCT08MDRDL?

A: Yes. Both parts are functionally and electrically identical 4-channel AND gate ICs in 14-SOIC packages with matching supply voltage ranges, operating temperatures, and logic specifications. Substitution is valid provided your assembly equipment supports the packaging format of the substitute part.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. The CD74HCT08MDRDL is supplied in Digi-Reel format, while the CD74HCT08M96 is available in both Cut Tape and Digi-Reel formats. All electrical and functional characteristics are identical.

Q: Are there any performance differences between these parts?

A: No performance differences exist. Both parts operate within the same voltage range (4.5V ~ 5.5V), temperature range (-55°C ~ 125°C), and quiescent current specifications (2 µA maximum). Logic function and package dimensions are identical.

Q: Which part should I select for new designs?

A: For new designs, either part is acceptable. However, the CD74HCT08M96 is recommended due to higher inventory availability and flexible packaging options, which provide greater supply chain flexibility and manufacturing process compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the CD74HCT08MDRDL and CD74HCT08M96 are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting environmental and regulatory requirements for commercial and industrial applications.

Q: Can I mix these parts in the same production batch?

A: Yes. Since both parts are functionally and electrically identical with the same 14-SOIC package dimensions, they can be used interchangeably within the same circuit design and production batch, provided your assembly equipment supports both packaging formats.
