CD4060BCMX Equivalent & Substitute Parts

Part Overview

The CD4060BCMX is a 14-bit binary counter IC manufactured by onsemi in the 4000B logic series. This component functions as a negative edge-triggered counter with a maximum count rate of 12 MHz, operating across a supply voltage range of 3 V to 15 V and temperature range of -55°C to 125°C. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. Substitute parts maintain the core binary counter functionality while offering improved availability, extended voltage ratings, or enhanced performance characteristics within the same logic family.

Number of Elements: 1
Trigger Type: Negative Edge
Package / Case: 16-SOIC form factor (0.154", 3.90mm Width)
Mounting Type: Surface Mount
Series: 4000B

Allowable Variations:

Count Rate: Substitute parts may equal or exceed 12 MHz
Voltage - Supply: Substitute parts may equal or exceed the 3 V ~ 15 V range (extended to 18 V is acceptable)
Operating Temperature: Substitute parts may equal or exceed the -55°C ~ 125°C range
Reset Type: Asynchronous reset is preferred but not mandatory for substitution
Product Status: Active status is preferred over obsolete

Substitute parts are grouped into two categories: direct substitutes (identical electrical specifications with improved availability) and parametric equivalents (enhanced performance or extended ratings within compatible parameters).

Engineering Selection Recommendations

Primary Substitutes (Recommended for Direct Replacement):

CD4060BM, CD4060BM96, and CD4060BMT from Texas Instruments are the preferred substitutes. These parts maintain identical count rate (12 MHz), asynchronous reset functionality, and temperature range (-55°C ~ 125°C) as the CD4060BCMX while offering extended voltage supply range (3 V ~ 18 V) and active product status. CD4060BM96 provides the highest inventory availability (97,700 pcs) and is supplied in Cut Tape & Digi-Reel packaging for production volumes.

Alternative Substitutes (Extended Performance):

MC14060BDG and MC14060BDR2G from onsemi provide enhanced count rate (17 MHz) and extended voltage range (3 V ~ 18 V) while maintaining the full temperature range (-55°C ~ 125°C). These parts are suitable for applications where higher clock frequencies are beneficial.

Performance-Enhanced Alternatives (Conditional Use):

HEC4060BT,112, HEC4060BT,118 from NXP USA Inc., and HEF4060BT,653 from Nexperia USA Inc. offer significantly higher count rates (30 MHz) and maintain asynchronous reset. However, these parts operate within a narrower temperature range (-40°C ~ 85°C) and voltage supply range (3 V ~ 15 V). Selection of these parts is appropriate only when the application does not require the extended temperature range of the original CD4060BCMX.

Packaging Consideration:

CD4060BNSR from Texas Instruments uses a 16-SOIC package with 0.209" width, differing from the standard 0.154" width of the CD4060BCMX. This part is suitable only if PCB layout accommodates the wider package footprint.

All recommended substitutes comply with RoHS3 and maintain REACH Unaffected status, consistent with the original part's compliance profile.

Frequently Asked Questions (FAQ)

Q: Can MC14060BDG replace CD4060BCMX directly?

A: MC14060BDG is functionally compatible as a 14-bit binary counter in the 4000B series with identical package and mounting type. The higher count rate (17 MHz vs. 12 MHz) and extended voltage range (3 V ~ 18 V) are backward compatible. However, the reset type is not specified for MC14060BDG, whereas CD4060BCMX specifies asynchronous reset. Verify reset behavior requirements in your application before substitution.

Q: What is the difference between CD4060BM and CD4060BM96?

A: Both parts are electrically identical CD4060 binary counters from Texas Instruments with 12 MHz count rate, asynchronous reset, and -55°C ~ 125°C operating range. The primary difference is packaging: CD4060BM is supplied in Tube packaging, while CD4060BM96 is supplied in Cut Tape & Digi-Reel format. CD4060BM96 is preferred for production environments requiring reel-based component handling.

Q: Why do HEC4060BT and HEF4060BT parts have different temperature ranges?

A: HEC4060BT (NXP USA Inc.) and HEF4060BT (Nexperia USA Inc.) are optimized for commercial and industrial temperature ranges (-40°C ~ 85°C) rather than the extended military-grade range (-55°C ~ 125°C) of the CD4060BCMX. These parts are suitable only for applications operating within the narrower temperature window. If your design requires operation at -55°C or above 85°C, select CD4060BM, CD4060BM96, or MC14060BDR2G instead.

Q: Is CD4060BNSR compatible with CD4060BCMX?

A: CD4060BNSR maintains identical electrical specifications and asynchronous reset functionality. However, the package width differs: CD4060BNSR uses 16-SOIC (0.209", 5.30mm) versus CD4060BCMX at 16-SOIC (0.154", 3.90mm). Direct PCB substitution is not possible without layout modification. Use this part only if your PCB design accommodates the wider package footprint.

Q: Which substitute offers the best availability?

A: CD4060BM96 from Texas Instruments provides the highest inventory (97,700 pcs) and is actively produced in Cut Tape & Digi-Reel packaging. HEF4060BT,653 from Nexperia USA Inc. also offers substantial availability (20,828 pcs) in Tape & Reel format. Both are suitable for high-volume production requirements.

Q: Can I use HEF4060BT,653 in a design requiring -55°C operation?

A: No. HEF4060BT,653 operates within -40°C ~ 85°C range and is not rated for -55°C operation. For applications requiring extended low-temperature performance, use CD4060BM, CD4060BM96, MC14060BDG, or MC14060BDR2G, all of which support -55°C minimum operating temperature.
