Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD4023BPW are determined by strict equivalence across the following critical parameters:

• Logic Type: NAND Gate (3 channels, 3 inputs per channel)
• Voltage - Supply: 3V ~ 18V
• Current - Quiescent (Max): 1 µA
• Current - Output High, Low: 3.4mA, 3.4mA
• Input Logic Level - Low: 1.5V ~ 4V
• Input Logic Level - High: 4.6V ~ 11V
• Max Propagation Delay @ V, Max CL: 90ns @ 15V, 50pF
• Operating Temperature: -55°C ~ 125°C
• Package / Case: 14-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount

The CD4023BPWR meets all electrical and mechanical specifications required for direct substitution. The primary difference is packaging format: the CD4023BPW is supplied in Tube packaging, while the CD4023BPWR is supplied in Tape & Reel (TR) format. Both are manufactured by Texas Instruments and belong to the 4000B series.

Parameter Comparison

Engineering Selection Recommendations

The CD4023BPWR is the direct electrical and mechanical equivalent of the CD4023BPW. Both parts are ROHS3 compliant and carry identical electrical specifications across all functional parameters. The CD4023BPWR maintains active product status with Texas Instruments, ensuring continued availability and supply chain support.

Selection between these parts depends on packaging requirements and procurement volume. The Tube packaging of the CD4023BPW is suitable for lower-volume applications and manual assembly processes. The Tape & Reel (TR) packaging of the CD4023BPWR is optimized for automated assembly and higher-volume production environments.

Both parts carry MSL Level 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control requirements during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can the CD4023BPWR be used as a direct replacement for the CD4023BPW?

A: Yes. Both parts are electrically and mechanically identical. They share the same logic function (3-channel NAND gate with 3 inputs), electrical specifications, operating temperature range, and 14-TSSOP package dimensions. The only difference is the packaging format: Tube versus Tape & Reel.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging supplies components in plastic tubes, typically used for manual assembly and lower-volume applications. Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for automated pick-and-place assembly equipment and higher-volume production. Both formats contain the same component.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the CD4023BPW and CD4023BPWR are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL Level 1). They meet the same regulatory and environmental standards.

Q: Why is the CD4023BPW discontinued while the CD4023BPWR remains active?

A: Product discontinuation decisions are based on market demand and supply chain optimization. The Tape & Reel format (CD4023BPWR) typically supports higher-volume automated manufacturing, while Tube packaging (CD4023BPW) serves lower-volume segments. The active status of the CD4023BPWR ensures continued availability for applications requiring this logic function.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by matching: logic type (NAND gate, 3 channels, 3 inputs), supply voltage range (3V ~ 18V), quiescent current (1 µA max), output current (3.4mA), input logic levels, propagation delay (90ns @ 15V, 50pF), operating temperature range (-55°C ~ 125°C), and package type (14-TSSOP surface mount).
