CD4011BNS NAND Gate IC Equivalent & Substitute Parts

Part Overview

The CD4011BNS is a NAND Gate IC featuring 4 channels with 2 inputs per channel in a 14-SO surface mount package. Manufactured by Texas Instruments, this logic component operates across a wide supply voltage range of 3V to 18V and is designed for general-purpose digital logic applications. The CD4011BNS is currently discontinued at DiGi Electronics, making identification of compatible substitute parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4011BNS is determined by strict equivalence across the following critical parameters:

Functional Parameters:

• Logic Type: NAND Gate (4-channel, 2-input configuration)
• Number of Circuits: 4
• Number of Inputs: 2 per circuit

Electrical Parameters:

• Voltage - Supply: 3V ~ 18V
• Operating Temperature: -55°C ~ 125°C
• Input Logic Levels: Low 1.5V ~ 4V, High 3.5V ~ 11V

Physical Parameters:

• Package / Case: 14-SOIC (0.209", 5.30mm Width)
• Mounting Type: Surface Mount

Compliance Parameters:

• RoHS Status: ROHS3 Compliant

The CD4011BNSR meets all these criteria and qualifies as a direct substitute. Differences in quiescent current, output current, and packaging format (Tape & Reel versus bulk) do not affect functional substitutability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The CD4011BNSR is a direct functional equivalent to the CD4011BNS and is suitable for substitution in applications requiring NAND gate logic with the specified electrical and thermal characteristics. The CD4011BNSR maintains active product status with Texas Instruments, ensuring continued availability and supply chain reliability.

Key advantages of the CD4011BNSR include reduced quiescent current consumption (1 µA versus 5 µA) and lower output current requirements (3.4mA versus 6.8mA), which may provide benefits in power-constrained applications. Both parts maintain identical propagation delay specifications and operate across the same supply voltage and temperature ranges.

Both parts are ROHS3 compliant and carry the same ECCN and HTSUS classifications, confirming regulatory equivalence. The CD4011BNSR is available in Tape & Reel packaging format, which is standard for high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Can the CD4011BNSR replace the CD4011BNS in existing designs?

A: Yes. The CD4011BNSR is functionally equivalent across all critical parameters: logic type, circuit count, input configuration, supply voltage range, operating temperature range, propagation delay, and package dimensions. Direct substitution is supported without circuit modification.

Q: What are the differences between CD4011BNS and CD4011BNSR?

A: The primary differences are product status and packaging format. The CD4011BNS is discontinued; the CD4011BNSR is active. The CD4011BNSR is supplied in Tape & Reel format, while the CD4011BNS was supplied in bulk packaging. Additionally, the CD4011BNSR exhibits lower quiescent current (1 µA) and output current (3.4mA) compared to the CD4011BNS (5 µA and 6.8mA respectively).

Q: Are there any compatibility concerns with the 14-SOIC package?

A: No. Both parts use identical 14-SOIC (0.209", 5.30mm Width) packaging. PCB footprints, solder reflow profiles, and assembly processes are fully compatible.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the CD4011BNS and CD4011BNSR are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: Which part should be selected for new designs?

A: The CD4011BNSR should be selected for new designs due to its active product status, ensuring long-term availability and supply chain continuity. The improved power efficiency characteristics (lower quiescent and output currents) provide additional design benefits.
