Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD4016BCMX is determined by the following critical parameters:

• Circuit Configuration: 1 x 1:1 bilateral or SPST-NO switch topology with 4 independent circuits
• Package Type: 14-SOIC surface mount package (0.154", 3.90mm width)
• Voltage Supply Range: Minimum 3V operation capability
• Operating Temperature Range: -55°C ~ 125°C
• Mounting Type: Surface mount

Substitute parts are grouped into two categories:

Category A - Direct Functional Equivalents (4000B Series & Compatible Logic Switches) Parts maintaining the same bilateral switch architecture, voltage supply source (dual supply), and full temperature range (-55°C ~ 125°C). These include CD4016BM, CD4016BM96, CD4016BMT, and CD4016BNSR from Texas Instruments, and MC14016BDR2G and MC14016BDG from onsemi.

Category B - Functional Alternatives (CMOS Logic Switches with Enhanced Performance) Parts with SPST-NO switch topology, 4 independent circuits, and 14-SOIC packaging but with different electrical characteristics. These include HEF4016BT,653 from Nexperia and CD74HC4016M96 and CD74HC4016MT from Texas Instruments. These parts operate at different voltage ranges and offer improved performance metrics.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility)

CD4016BM96 and CD4016BMT from Texas Instruments are the preferred substitutes. Both maintain the bilateral FET switch architecture, support the full -55°C ~ 125°C operating temperature range, and are available in the standard 14-SOIC (0.154", 3.90mm) package. CD4016BM96 is currently Active with the highest inventory availability (30,877 pcs), making it the most accessible option for new designs and production requirements.

Secondary Substitutes (Extended Voltage Range)

MC14016BDR2G and MC14016BDG from onsemi provide extended voltage supply range (3V ~ 18V) compared to the original specification (3V ~ 15V), with identical circuit configuration and temperature range. MC14016BDR2G is packaged in Tape & Reel format and maintains Active product status. Both parts are ROHS3 compliant and carry MSL 1 rating.

Alternative Substitutes (Different Architecture)

HEF4016BT,653 from Nexperia operates with SPST-NO switch topology instead of bilateral configuration, with a narrower operating temperature range (-40°C ~ 85°C). This part is suitable only for applications not requiring the full -55°C ~ 125°C temperature specification. CD74HC4016M96 and CD74HC4016MT offer enhanced performance with lower on-state resistance (170Ohm) but operate at reduced voltage range (2V ~ 10V), limiting compatibility with designs requiring 15V operation.

Package Consideration

CD4016BNSR uses a wider 14-SOIC package (0.209", 5.30mm) compared to the standard 14-SOIC (0.154", 3.90mm). This part is suitable only for applications where PCB layout accommodates the larger package footprint.

Frequently Asked Questions (FAQ)

Q: Can MC14016BDR2G replace CD4016BCMX in all applications?

A: MC14016BDR2G is functionally compatible with CD4016BCMX for applications operating within the overlapping voltage range (3V ~ 15V). The extended voltage capability (up to 18V) does not affect compatibility at lower voltages. Both parts maintain identical circuit configuration, temperature range, and package specifications.

Q: What is the difference between CD4016BM96 and CD4016BMT?

A: Both parts are functionally identical bilateral FET switches with the same electrical specifications. The difference is packaging format: CD4016BM96 is supplied in Cut Tape (CT) & Digi-Reel format, while CD4016BMT is supplied in Tape & Reel (TR) format. Selection depends on procurement and assembly requirements.

Q: Why is HEF4016BT,653 listed as an alternative rather than a direct substitute?

A: HEF4016BT,653 uses SPST-NO switch topology instead of bilateral architecture and operates at a reduced temperature range (-40°C ~ 85°C). It is suitable only for applications not requiring bilateral switching capability or full military-grade temperature specifications.

Q: Is CD74HC4016M96 compatible with designs requiring 15V operation?

A: No. CD74HC4016M96 operates at maximum 10V supply voltage, making it incompatible with applications requiring 15V operation. This part is suitable only for low-voltage designs operating within the 2V ~ 10V range.

Q: What is the significance of the package width difference in CD4016BNSR?

A: CD4016BNSR uses a 14-SOIC package with 5.30mm width compared to the standard 3.90mm width. This larger footprint requires verification of PCB layout compatibility before substitution. Pin configuration and electrical specifications remain identical to other 14-SOIC variants.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification. The original CD4016BCMX does not specify RoHS status due to its Obsolete classification, but all active and last-time-buy alternatives meet current environmental compliance requirements.

Q: Which substitute offers the best long-term availability?

A: CD4016BM96 from Texas Instruments is currently Active with the highest inventory (30,877 pcs), providing the best long-term availability for new designs. MC14016BDR2G and MC14016BDG from onsemi are also Active status alternatives with substantial inventory levels.
