Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74HCT4060D,652 is determined by the following critical parameters that must remain constant across all equivalent parts:

• Logic Type: Binary Counter
• Number of Bits per Element: 14 Bit
• Trigger Type: Negative Edge
• Reset: Asynchronous
• Voltage - Supply: 4.5 V ~ 5.5 V
• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Base Product Number: 74HCT4060

The substitute parts identified (CD74HCT4060M, CD74HCT4060M96, and CD74HCT4060MT) maintain all core functional and mechanical parameters. Variations in count rate (30 MHz vs. 88 MHz), operating temperature range, product status, and RoHS compliance are secondary considerations that do not affect functional substitution within the 74HCT4060 family.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring the 74HCT4060D,652, the following selection criteria apply based on product status and compliance requirements:

CD74HCT4060M96 (Texas Instruments) is the preferred substitute for new designs and ongoing procurement. This part maintains active product status, ROHS3 compliance, and unlimited moisture sensitivity level (MSL: 1), ensuring long-term availability and regulatory alignment.

CD74HCT4060MT (Texas Instruments) is suitable for applications where Last Time Buy inventory is acceptable. This part also maintains ROHS3 compliance and unlimited MSL rating, with comparable electrical and mechanical specifications to CD74HCT4060M96.

CD74HCT4060M (Harris Corporation) is available as a functional equivalent but carries RoHS non-compliance status and obsolete product classification. This part should be considered only when supply constraints prevent use of ROHS3-compliant alternatives.

All three substitute parts operate within the same voltage supply range (4.5 V ~ 5.5 V) and maintain identical package geometry (16-SOIC). The reduced count rate specification (30 MHz vs. 88 MHz) in substitute parts does not affect functional compatibility in applications designed for the 74HCT4060 family, as the original 88 MHz specification represents maximum performance capability rather than a functional requirement.

Frequently Asked Questions (FAQ)

Q: Can CD74HCT4060M96 directly replace 74HCT4060D,652 in existing designs?

A: Yes. Both parts share identical logic type (14-bit binary counter), trigger type (negative edge), supply voltage range (4.5 V ~ 5.5 V), and 16-SOIC package geometry. Pin-for-pin compatibility is maintained across the 74HCT4060 family.

Q: What is the significance of the count rate difference (88 MHz vs. 30 MHz)?

A: The 74HCT4060D,652 specifies a maximum count rate of 88 MHz, while substitute parts specify 30 MHz. This represents the maximum operating frequency for each device. Applications designed for the 74HCT4060 family operate within the specified limits of the substitute part. If your application requires operation above 30 MHz, verify that the original 88 MHz specification is a functional requirement rather than a maximum rating.

Q: Are all substitute parts RoHS compliant?

A: CD74HCT4060M96 and CD74HCT4060MT are ROHS3 compliant. CD74HCT4060M is RoHS non-compliant. For applications subject to RoHS regulations, use CD74HCT4060M96 or CD74HCT4060MT.

Q: What is the difference between Tape & Reel and Tube packaging?

A: Tape & Reel (TR) packaging is standard for automated assembly and high-volume production. Tube packaging is used for lower-volume applications and manual assembly. Both packaging formats contain identical die and electrical specifications. Select based on your assembly process requirements.

Q: Why is CD74HCT4060M96 recommended over CD74HCT4060MT?

A: CD74HCT4060M96 maintains active product status, ensuring continued availability and manufacturing support. CD74HCT4060MT is classified as Last Time Buy, indicating limited future availability. For new designs and long-term supply planning, CD74HCT4060M96 is the preferred choice.

Q: Are the operating temperature ranges interchangeable?

A: The 74HCT4060D,652 operates from -40°C to 125°C, while substitute parts operate from -55°C to 125°C. The substitute parts provide an extended lower temperature range. Both ranges cover standard industrial and commercial operating conditions. Select based on your specific application temperature requirements.
