MM74HC4060SJ Equivalent & Substitute Parts

Part Overview

The MM74HC4060SJ is a 14-bit binary counter IC manufactured by onsemi in 16-SOP surface mount packaging. This logic component operates as an up counter with asynchronous reset and negative edge triggering, designed for applications requiring frequency division and counting functions across industrial and commercial temperature ranges (-40°C to 85°C). The part is currently listed as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain functional equivalence in counter architecture, bit width, trigger characteristics, and electrical operating parameters while accommodating available packaging and product status options.

Substitute Part Grouping Explanation

Substitution of the MM74HC4060SJ is determined by the following critical parameters:

Functional Requirements: All substitute parts must be 14-bit binary counters with negative edge triggering and asynchronous reset to maintain circuit compatibility.

Electrical Compatibility: Supply voltage range (2 V ~ 6 V) and operating temperature range (-40°C ~ 85°C minimum) must be met or exceeded.

Package Compatibility: Surface mount 16-pin SOIC packaging is required. Two package width variants exist: 0.209" (5.30mm) and 0.154" (3.90mm). Parts with the 0.154" width variant require PCB layout verification but are electrically compatible.

Product Status Consideration: Active status parts are preferred for new designs. Last Time Buy and obsolete designations indicate limited availability.

Compliance: RoHS3 compliance and REACH unaffected status are maintained across all substitute options.

Engineering Selection Recommendations

Direct Substitutes (14-bit, Same Package Width 5.30mm):

SN74HC4060NSR is the primary direct substitute. It maintains identical package dimensions (16-SOIC 0.209" width), equivalent electrical specifications, and active product status. This part requires no PCB layout modifications and provides the highest compatibility with the original MM74HC4060SJ footprint.

Preferred Substitutes (14-bit, Compact Package 3.90mm):

CD74HC4060M96 is recommended for new designs requiring 14-bit counter functionality. It offers active product status, highest inventory availability (14,215 pcs), extended temperature range (-55°C to 125°C), and superior count rate performance (35 MHz). The narrower 3.90mm package width requires PCB layout verification but provides space optimization benefits. This part is RoHS3 compliant and REACH unaffected.

SN74HC4060DR provides an alternative with active status and 5,353 pcs inventory. It maintains the -40°C to 85°C temperature range and 33 MHz count rate while using the compact 3.90mm package width.

Limited Availability Substitutes (Last Time Buy Status):

CD74HC4060MT, SN74HC4060D, and SN74HC4060DT are designated Last Time Buy. These parts maintain 14-bit functionality and are suitable for applications where extended temperature range (-55°C to 125°C) is beneficial, but procurement should prioritize active status alternatives due to limited future availability.

Functional Alternative (12-bit Counter):

SN74HC4040NSR is a 12-bit binary counter suitable only for applications where reduced bit width is acceptable. This part is not a direct substitute but may serve specific applications requiring fewer counter stages. It maintains the 5.30mm package width and active product status.

Frequently Asked Questions (FAQ)

Q: Can SN74HC4060NSR directly replace MM74HC4060SJ without PCB modifications?

A: Yes. SN74HC4060NSR maintains identical 16-SOIC 0.209" (5.30mm) package dimensions, equivalent electrical specifications, and identical pin configuration. No PCB layout changes are required.

Q: What is the difference between the 5.30mm and 3.90mm package width variants?

A: Both are 16-SOIC packages with identical pin pitch and electrical characteristics. The 3.90mm width variant is a compact form factor. PCB footprints differ in body width; verify your PCB design accommodates the selected package width before assembly.

Q: Why is CD74HC4060M96 recommended despite the package width difference?

A: CD74HC4060M96 offers superior specifications including active product status, highest inventory availability, extended temperature range (-55°C to 125°C), and higher count rate (35 MHz). The 3.90mm package width requires PCB verification but provides space optimization. Select this part for new designs where layout permits.

Q: Is SN74HC4040NSR a suitable substitute?

A: SN74HC4040NSR is a 12-bit counter, not a 14-bit counter. It is not functionally equivalent to MM74HC4060SJ. Use only if your application requires 12-bit counter functionality and can accommodate reduced bit width.

Q: What is the significance of "Last Time Buy" product status?

A: Last Time Buy indicates the manufacturer will discontinue production after a specified date. Parts with this designation have limited future availability. For ongoing production requirements, prioritize Active status parts such as SN74HC4060NSR or CD74HC4060M96.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant and REACH unaffected, maintaining environmental compliance equivalent to the original MM74HC4060SJ.

Q: Can I use parts with extended temperature range (-55°C to 125°C) in applications requiring only -40°C to 85°C?

A: Yes. Extended temperature range parts (CD74HC4060M, CD74HC4060M96, CD74HC4060MT) are fully compatible with applications requiring the standard -40°C to 85°C range. Extended range provides additional design margin and future flexibility.
