CD4023BE-NG Equivalent & Substitute Parts

Part Overview

The CD4023BE-NG is a NAND Gate IC featuring 3 channels with 3 inputs per channel, manufactured by Texas Instruments in the 4000B logic series. This component is classified as obsolete, which necessitates identification of active equivalent parts for new designs and ongoing production requirements. The CD4023BE-NG operates across a wide supply voltage range of 3V to 18V and is packaged in a 14-DIP through-hole configuration suitable for breadboard and PCB prototyping applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4023BE-NG is determined by strict equivalence across the following electrical and mechanical parameters:

Functional Equivalence Criteria:

• Logic Type: NAND Gate (3 channels, 3 inputs per channel)
• Voltage Supply Range: 3V ~ 18V
• Input Logic Levels: Low 1.5V ~ 4V, High 3.5V ~ 11V
• Max Propagation Delay: 90ns @ 15V, 50pF
• Operating Temperature Range: -55°C ~ 125°C
• RoHS3 Compliance

Mechanical Compatibility Considerations:

• Package type determines mounting method (through-hole vs. surface mount)
• Pin count and pinout must remain identical (14-pin configuration)
• Physical dimensions affect PCB layout and assembly process

The CD4023BPWR is identified as the manufacturer-recommended substitute. While both parts maintain identical electrical specifications and functional performance, they differ in packaging format and product status, with CD4023BPWR being an active product in surface-mount configuration.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Product Replacement: The CD4023BE-NG is classified as obsolete. The CD4023BPWR is the active equivalent from Texas Instruments and maintains full electrical compatibility with identical logic performance, supply voltage range, input/output specifications, and propagation delay characteristics.

Compliance Status: Both parts are ROHS3 compliant, meeting environmental regulatory requirements for new designs and manufacturing operations.

Packaging Considerations: Selection between these parts depends on assembly methodology:

• CD4023BE-NG (14-DIP through-hole): Suitable for through-hole PCB assembly, breadboard prototyping, and legacy systems
• CD4023BPWR (14-TSSOP surface-mount): Required for modern surface-mount PCB assembly and high-density layouts

Performance Characteristics: The CD4023BPWR demonstrates improved power efficiency with reduced quiescent current (1 µA vs. 5 µA) and lower output current (3.4mA vs. 6.8mA), while maintaining identical propagation delay and logic thresholds.

Frequently Asked Questions (FAQ)

Q: Can CD4023BPWR directly replace CD4023BE-NG in existing through-hole PCB designs?

A: No. CD4023BPWR uses 14-TSSOP surface-mount packaging, while CD4023BE-NG uses 14-DIP through-hole packaging. Direct PCB substitution requires either design modification to accommodate surface-mount footprint or use of an adapter carrier. For new designs, CD4023BPWR is the recommended active product.

Q: Are the electrical specifications identical between CD4023BE-NG and CD4023BPWR?

A: The core logic specifications are identical: 3-channel NAND gate, 3 inputs per channel, 3V-18V supply voltage, -55°C to 125°C operating range, and 90ns propagation delay at 15V with 50pF load. Quiescent and output currents differ, with CD4023BPWR showing lower power consumption.

Q: What is the significance of the obsolete status of CD4023BE-NG?

A: Obsolete status indicates the part is no longer manufactured or supported by Texas Instruments. Existing inventory may be limited. CD4023BPWR is the active replacement for new production and long-term availability.

Q: Do both parts meet RoHS3 compliance requirements?

A: Yes. Both CD4023BE-NG and CD4023BPWR are ROHS3 compliant, suitable for applications requiring environmental regulatory adherence.

Q: What is the difference in moisture sensitivity between these parts?

A: CD4023BE-NG has no applicable moisture sensitivity level (through-hole packaging). CD4023BPWR is rated MSL 1 (Unlimited), indicating minimal moisture sensitivity for surface-mount handling and storage.
