Substitute Part Grouping Explanation
Substitution eligibility for the CD4067BPW is determined by the following critical parameters: 16:1 multiplexer/demultiplexer configuration, single-circuit topology, 24-TSSOP package compatibility, and surface mount mounting type. The on-state resistance, supply voltage range, bandwidth, and operating temperature range define functional equivalence boundaries.
CD4067BPWR qualifies as a direct equivalent manufactured by Texas Instruments with identical electrical specifications and package footprint, differentiated only by packaging format (Tape & Reel versus Tube).
74HC4067PW,118 and 74HCT4067PW,118 manufactured by Nexperia USA Inc. provide functional substitution with modified electrical characteristics: reduced on-state resistance (120Ohm), altered supply voltage ranges, and enhanced bandwidth performance. These parts maintain the 16:1 multiplexer configuration and 24-TSSOP package but operate within different voltage and temperature parameters.

Engineering Selection Recommendations
CD4067BPWR is the primary recommended substitute for CD4067BPW. Both parts are manufactured by Texas Instruments with identical electrical specifications and operating parameters. The substitution involves only packaging format differentiation: CD4067BPWR is supplied in Tape & Reel format with Active product status, ensuring continued availability and supply chain stability compared to the Last Time Buy status of CD4067BPW.
74HC4067PW,118 and 74HCT4067PW,118 provide functional alternatives when supply constraints necessitate cross-manufacturer substitution. Both Nexperia parts maintain ROHS3 compliance and MSL 1 rating. Selection between these alternatives depends on supply voltage requirements: 74HC4067PW,118 operates across 2V ~ 10V, while 74HCT4067PW,118 is constrained to 4.5V ~ 5.5V. The Nexperia alternatives feature reduced on-state resistance (120Ohm versus 240Ohm) and enhanced bandwidth (100MHz versus 14MHz), which may require circuit validation in applications sensitive to impedance characteristics.
Frequently Asked Questions (FAQ)
Q: Can CD4067BPWR directly replace CD4067BPW without circuit modification?
A: Yes. CD4067BPWR is electrically and functionally identical to CD4067BPW. Both parts share the same on-state resistance (240Ohm), supply voltage range (3V ~ 18V), bandwidth (14MHz), and operating temperature range (-55°C ~ 125°C). The substitution involves only packaging format change from Tube to Tape & Reel.
Q: What are the key differences between CD4067BPWR and the Nexperia 74HC4067PW,118?
A: The primary differences are manufacturer, on-state resistance, and supply voltage range. CD4067BPWR maintains 240Ohm on-state resistance and 3V ~ 18V supply range. 74HC4067PW,118 reduces on-state resistance to 120Ohm and limits supply voltage to 2V ~ 10V. Both maintain 24-TSSOP package compatibility and ROHS3 compliance.
Q: Is 74HCT4067PW,118 suitable for applications requiring the full 3V ~ 18V supply range of CD4067BPW?
A: No. 74HCT4067PW,118 operates only within 4.5V ~ 5.5V supply range, making it unsuitable for applications requiring the extended 3V ~ 18V range of CD4067BPW. 74HC4067PW,118 supports 2V ~ 10V and is the appropriate Nexperia alternative for wider supply voltage applications.
Q: Are all substitute parts available in 24-TSSOP surface mount package?
A: Yes. CD4067BPWR, 74HC4067PW,118, and 74HCT4067PW,118 are all supplied in 24-TSSOP (0.173", 4.40mm Width) surface mount package, ensuring PCB footprint compatibility with CD4067BPW designs.
Q: What is the impact of reduced on-state resistance in Nexperia alternatives on circuit performance?
A: Nexperia parts feature 120Ohm on-state resistance compared to 240Ohm in Texas Instruments CD4067 variants. Lower on-state resistance reduces signal attenuation and voltage drop across the switch, potentially improving signal integrity in low-impedance applications. Circuit validation is necessary to confirm compatibility with existing impedance-sensitive designs.
Q: Do all substitute parts maintain the same leakage current specifications?
A: CD4067BPW, CD4067BPWR, and 74HC4067PW,118 specify 100nA maximum leakage current. 74HCT4067PW,118 specifies 800nA maximum leakage current, representing an 8x increase. Applications with strict leakage current requirements should prioritize CD4067BPWR or 74HC4067PW,118.
Q: What is the operating temperature range difference between CD4067BPW and Nexperia alternatives?
A: CD4067BPW and CD4067BPWR operate across -55°C ~ 125°C. Both Nexperia parts (74HC4067PW,118 and 74HCT4067PW,118) operate across -40°C ~ 125°C, providing a narrower low-temperature range. Applications requiring operation below -40°C must use Texas Instruments CD4067 variants.
