CD4053BE-NG Equivalent & Substitute Parts

Part Overview

The CD4053BE-NG is a 3-circuit IC switch with 2:1 multiplexer/demultiplexer functionality manufactured by Texas Instruments. This component operates as a single-pole double-throw (SPDT) analog switch with 240Ohm on-state resistance and supports supply voltages from 3V to 20V. The CD4053BE-NG is classified as Last Time Buy, indicating discontinued production. Identifying equivalent substitute parts is necessary to ensure continued component availability for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution of the CD4053BE-NG is determined by strict equivalence across the following critical parameters:

Functional Parameters: Switch circuit type (SPDT), multiplexer configuration (2:1), and number of circuits (3) must be identical. These define the core switching topology and cannot vary.

Electrical Performance Parameters: On-state resistance (240Ohm maximum), channel-to-channel matching (5Ohm), supply voltage range (3V ~ 20V single supply), bandwidth (30MHz), leakage current (100nA maximum), and crosstalk (-40dB @ 6MHz) establish the electrical operating envelope. Substitute parts must meet or exceed these specifications.

Physical Parameters: Package type (16-DIP), case dimensions (0.300", 7.62mm), and mounting method (Through Hole) ensure mechanical compatibility with existing PCB designs and assembly processes.

Compliance Parameters: RoHS3 compliance is required for regulatory alignment.

The CD4053BE (without the -NG suffix) qualifies as a direct substitute based on identical functional, electrical, and physical parameters while maintaining active product status.

Engineering Selection Recommendations

The CD4053BE serves as the direct substitute for the CD4053BE-NG. Both parts are manufactured by Texas Instruments and share identical electrical specifications, functional configuration, and physical packaging. The primary distinction is product status: the CD4053BE-NG is Last Time Buy, while the CD4053BE maintains Active status with significantly higher inventory availability (50,400 pieces versus 787 pieces).

From a compliance perspective, both parts are ROHS3 compliant, ensuring regulatory alignment for applications subject to hazardous substance restrictions. The CD4053BE additionally provides dual supply voltage capability (±2.5V ~ 9V), which extends application flexibility beyond the single supply range specified for the CD4053BE-NG.

For new designs and ongoing production, the CD4053BE is the appropriate selection due to its active product status and sustained manufacturing support. Existing designs using the CD4053BE-NG can transition to the CD4053BE without circuit modification, as all critical electrical and mechanical parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the CD4053BE directly replace the CD4053BE-NG in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The CD4053BE operates within the same voltage range (3V ~ 20V single supply), maintains identical on-state resistance (240Ohm), and uses the same 16-DIP package. No circuit redesign is required.

Q: What is the significance of the -NG suffix on the CD4053BE-NG?

A: The -NG suffix indicates a specific packaging or distribution variant. The core device functionality remains identical to the CD4053BE. The primary difference is product lifecycle status: CD4053BE-NG is Last Time Buy, while CD4053BE is Active.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts meet identical specifications for on-state resistance (240Ohm maximum), channel-to-channel matching (5Ohm), leakage current (100nA maximum), bandwidth (30MHz), and crosstalk (-40dB @ 6MHz).

Q: Does the CD4053BE support dual supply operation?

A: Yes. The CD4053BE supports dual supply voltage (±2.5V ~ 9V) in addition to single supply operation (3V ~ 20V). This capability extends application flexibility compared to designs limited to single supply operation.

Q: What packaging options are available for these parts?

A: Both the CD4053BE-NG and CD4053BE are supplied in 16-DIP through-hole packages with 0.300" (7.62mm) spacing. The CD4053BE-NG is available in standard packaging, while the CD4053BE is supplied in Tube packaging.

Q: Are both parts RoHS compliant?

A: Yes. Both the CD4053BE-NG and CD4053BE are ROHS3 compliant, meeting regulatory requirements for hazardous substance restrictions.

Q: What is the recommended substitution path for discontinued CD4053BE-NG inventory?

A: Transition to the CD4053BE. This part maintains Active product status with established manufacturing support and higher inventory availability, ensuring long-term supply continuity.
