Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4016BPW is determined by the following critical parameters:

• Circuit Configuration: 1 x 1:1 multiplexer/demultiplexer topology with 4 independent circuits
• Voltage Supply Range: 3V to 18V dual supply operation
• Operating Temperature Range: -55°C to 125°C minimum
• Package Type: 14-TSSOP surface mount form factor
• Functional Classification: Bilateral FET switch or equivalent SPST switch topology
• Compliance: ROHS3 and REACH compliance status

Substitute parts must maintain compatibility across all these parameters. Parts are grouped by manufacturer origin and product status to facilitate selection based on availability and long-term support requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Texas Instruments, Active Status)

CD4066BPWR is the manufacturer-recommended substitute, offering active product status with identical voltage supply range (3V ~ 18V), operating temperature range (-55°C ~ 125°C), and 14-TSSOP packaging. This part provides superior long-term availability and supply chain continuity. On-state resistance specification of 240Ohm and -3dB bandwidth of 40MHz are documented parameters supporting high-frequency switching applications.

Secondary Substitute (Texas Instruments, Last Time Buy)

CD4066BPW maintains parametric equivalence to CD4016BPW with identical electrical specifications and packaging. However, Last Time Buy status indicates limited future availability. This part is suitable for immediate replacement but should not be selected for new long-term designs.

Cross-Manufacturer Alternatives

MC14066BDTR2G (onsemi) and BU4066BCFV-E2 (Rohm Semiconductor) provide functional equivalence with active product status. Both maintain the 4-circuit configuration and 3V ~ 18V supply range. MC14066BDTR2G preserves the full -55°C ~ 125°C temperature range. BU4066BCFV-E2 operates within -40°C ~ 85°C, suitable for commercial and industrial applications but not for extended military temperature specifications. BU4066BCFV-E2 specifies 280Ohm on-state resistance and 10pF channel capacitance, representing acceptable parameter variance within the bilateral switch category.

Compliance Verification

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original CD4016BPW specification.

Frequently Asked Questions (FAQ)

Q: Can CD4066BPWR directly replace CD4016BPW in existing designs?

A: Yes. Both parts share identical voltage supply range (3V ~ 18V), operating temperature range (-55°C ~ 125°C), and 14-TSSOP package footprint. The CD4066 variant is the manufacturer-recommended equivalent with active product status.

Q: What is the difference between CD4016BPW and CD4066BPW?

A: Both are Texas Instruments 4000B series bilateral switches with identical electrical specifications and packaging. The primary distinction is product status: CD4016BPW is Last Time Buy, while CD4066BPW is also Last Time Buy. For new designs, CD4066BPWR (active status) is preferred.

Q: Is BU4066BCFV-E2 suitable for military temperature applications?

A: No. BU4066BCFV-E2 operates within -40°C ~ 85°C, which does not meet the -55°C ~ 125°C specification of CD4016BPW. This part is limited to commercial and industrial temperature ranges.

Q: Are there packaging differences between substitute parts?

A: CD4016BPW, CD4066BPWR, CD4066BPW, and MC14066BDTR2G all use 14-TSSOP packaging with identical 0.173" width (4.40mm). BU4066BCFV-E2 uses 14-LSSOP packaging, which maintains the same pin count and footprint compatibility but with different lead configuration. Verify PCB layout compatibility before selection.

Q: What on-state resistance should I expect from substitute parts?

A: CD4066BPWR and CD4066BPW specify 240Ohm maximum on-state resistance. BU4066BCFV-E2 specifies 280Ohm maximum. CD4016BPW and MC14066BDTR2G do not provide on-state resistance specifications in the datasheet. For applications requiring specific resistance characteristics, CD4066 variants are recommended.

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

A: MC14066BDTR2G (onsemi) and BU4066BCFV-E2 (Rohm Semiconductor) both carry Active product status, indicating ongoing manufacturing and supply. CD4066BPWR also maintains Active status. Parts with Last Time Buy designation should be avoided for new designs requiring extended component lifecycle.
