Substitute Part Grouping Explanation

Substitution of the CD74HCT670MTE4 is determined by strict equivalence across the following critical parameters:

• Base product number (74HCT670 series)
• Circuit type and configuration (Register File, 1×1:1, 4 independent circuits)
• Electrical specifications (4.5V ~ 5.5V supply, -55°C ~ 125°C operating range)
• Package and pinout (16-SOIC form factor)
• Compliance certifications (ROHS3, REACH Unaffected, EAR99)

The CD74HCT670M qualifies as a direct substitute based on identical electrical characteristics, circuit configuration, and package specifications. The primary distinction is product status: CD74HCT670MTE4 is obsolete, while CD74HCT670M maintains active production status.

Parameter Comparison

Engineering Selection Recommendations

The CD74HCT670M is the appropriate substitute for the obsolete CD74HCT670MTE4. Both components are manufactured by Texas Instruments and share identical electrical specifications, circuit topology, and package geometry. The CD74HCT670M maintains active product status with current manufacturing support, ensuring long-term availability and supply chain continuity.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. The difference in packaging format (Tube versus Tape and Reel) does not affect functional compatibility or electrical performance.

Frequently Asked Questions (FAQ)

Q: Can CD74HCT670M be used as a direct replacement for CD74HCT670MTE4?

A: Yes. Both components share identical electrical specifications, circuit configuration, package type, and pinout. The CD74HCT670M is the active production equivalent.

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

A: The primary difference is product status. CD74HCT670MTE4 is obsolete, while CD74HCT670M is in active production. The packaging format differs (Tape and Reel versus Tube), but this does not affect electrical compatibility or performance.

Q: Are there any compliance or regulatory differences?

A: No. Both parts maintain identical ROHS3 compliance, REACH unaffected status, and EAR99 export classification.

Q: Does the packaging format affect circuit performance?

A: No. Packaging format (Tube or Tape and Reel) is a supply and handling consideration only. Electrical and functional characteristics remain identical.

Q: What operating conditions are supported by the substitute part?

A: The CD74HCT670M operates across the full temperature range of -55°C to 125°C with a supply voltage range of 4.5V to 5.5V, matching the original part specifications.
