Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD40106BPW is determined by the following criteria:

Core Functional Requirements:

• Logic Type: Inverter with 6 channels and Schmitt trigger inputs
• Package: 14-TSSOP surface mount form factor
• Supply Voltage Range: Minimum 3V to 18V compatibility
• Operating Temperature: -55°C to 125°C range

Electrical Compatibility Parameters:

• Input Logic Levels (Low and High thresholds)
• Output Current capabilities (High and Low)
• Quiescent Current consumption
• Propagation Delay characteristics
• Maximum voltage supply specification

All substitute parts listed maintain the same logic architecture, pin configuration, and package dimensions. Variations in quiescent current, output drive capability, and propagation delay do not prevent functional substitution when the application requirements fall within the specified ranges of the substitute part.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - CD40106BPWR (Texas Instruments): CD40106BPWR is the direct equivalent from the original manufacturer with identical electrical specifications and active product status. This part maintains the same quiescent current (4 µA), output drive capability (3.4mA), and propagation delay (120ns) as the discontinued CD40106BPW. The only difference is packaging format (Cut Tape & Digi-Reel versus Tube), which does not affect electrical performance. This is the recommended choice for designs requiring exact parameter matching and manufacturer continuity.

High-Performance Alternatives - MC14106BDTR2G, NLV14106BDTR2G, MC14584BDTR2G, NLV14584BDTR2G (onsemi): These onsemi parts offer improved performance characteristics with reduced quiescent current (1 µA versus 4 µA) and faster propagation delay (80ns versus 120ns). MC14106BDTR2G and NLV14106BDTR2G maintain identical input logic thresholds to the original part. NLV14106BDTR2G and NLV14584BDTR2G carry automotive-grade qualification (AEC-Q100) for applications requiring automotive reliability standards. The MC14584BDTR2G and NLV14584BDTR2G variants feature slightly different input logic level specifications (1.6V ~ 4.6V low threshold, 3.4V ~ 10.5V high threshold) and are suitable when these thresholds align with application requirements.

Alternative - HEF40106BTT,118 (Nexperia): HEF40106BTT,118 provides equivalent functionality with faster propagation delay (60ns) and maintains the same output drive capability (3.4mA) as the original part. The maximum supply voltage is limited to 15V (versus 18V for other alternatives) and the minimum operating temperature is -40°C (versus -55°C). This part is suitable for applications operating within these constraints and where faster switching speed is beneficial.

Selection Criteria:

• For exact parameter replacement: CD40106BPWR
• For improved performance with lower power consumption: MC14106BDTR2G or NLV14106BDTR2G
• For automotive applications: NLV14106BDTR2G or NLV14584BDTR2G
• For fastest propagation delay: HEF40106BTT,118
• For applications with different input thresholds: MC14584BDTR2G or NLV14584BDTR2G

All substitute parts are ROHS3 compliant and maintain the same 14-TSSOP package form factor, ensuring PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can CD40106BPWR be used as a direct replacement for CD40106BPW? A: Yes. CD40106BPWR is the active equivalent from Texas Instruments with identical electrical specifications. The only difference is packaging format (Cut Tape & Digi-Reel versus Tube), which does not affect circuit performance or pin configuration.

Q: What are the main differences between the onsemi and Nexperia alternatives? A: onsemi parts (MC14106BDTR2G, NLV14106BDTR2G, MC14584BDTR2G, NLV14584BDTR2G) offer lower quiescent current (1 µA) and faster propagation delay (80ns). Nexperia's HEF40106BTT,118 provides the fastest propagation delay (60ns) but limits maximum supply voltage to 15V and minimum operating temperature to -40°C. Input logic thresholds vary between manufacturers; verify compatibility with your specific application requirements.

Q: Are automotive-grade parts (NLV14106BDTR2G, NLV14584BDTR2G) required for non-automotive applications? A: No. Automotive-grade parts carry AEC-Q100 qualification but function identically to standard-grade equivalents in non-automotive circuits. Selection depends on application requirements and supply chain availability rather than functional necessity.

Q: What is the significance of the MC14584 and NLV14584 variants? A: MC14584BDTR2G and NLV14584BDTR2G are functionally equivalent inverter ICs with different input logic level specifications (1.6V ~ 4.6V low threshold, 3.4V ~ 10.5V high threshold) compared to the standard CD40106 variants. These parts are suitable when application input signal levels align with these thresholds.

Q: Can all substitute parts be used interchangeably on the same PCB? A: All listed parts share the same 14-TSSOP package and pin configuration, enabling direct PCB substitution without layout changes. However, verify that the specific part's electrical specifications (supply voltage range, input thresholds, output current, operating temperature) match your application requirements before selection.

Q: What is the impact of propagation delay differences between parts? A: Propagation delay ranges from 60ns (HEF40106BTT,118) to 120ns (CD40106BPW/CD40106BPWR). For most logic applications, these differences are negligible. Applications with strict timing requirements or high-frequency operation should verify that the selected part's propagation delay meets circuit timing constraints.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance, meeting environmental and regulatory requirements for commercial and industrial applications.
